Academic literature on the topic 'Boswellia Serrata Extract'

This study is aimed at investigating the cytotoxicity, anti-inflammatory, and angiogenic activities of two Boswellia serrata extracts on primary culture of porcine aortic endothelial cells (pAECs). Chemical characterization of a dry extract (extract A) and a hydroenzymatic extract (extract G) of B. serrata was performed by HPLC using pure boswellic acids (BAs) as standard. In cultured pAECs, extract G improved cell viability, following LPS challenge, in a dose-dependent manner and did not show any toxic effect. On the other hand, extract A was toxic at higher doses and restored pAEC viability after LPS challenge only at lower doses. Pure BAs, used at the same concentrations as those determined in the phytoextracts, did not contrast LPS-induced cytotoxicity. Extract A showed proangiogenic properties at the lowest dose, and the same result was observed using pure AKBA at the corresponding concentration, whereas extract G did not show any effect on the migration capacity of endothelial cells. In conclusion, an anti-inflammatory activity of B. serrata extracts on endothelial cells was reported, though cytotoxicity or proliferative stimulation can occur instead of a protective effect, depending on the dose and the formulation.

Abstract Objectives The anti-inflammatory activity of Boswellia serrata extracts (BSE) is well known. BSE comprises boswellic acids (BA) such as 3-O-acetyl-11-keto-beta-boswellic acid (AKBA) and 11-keto-boswellic acid (KBA) as major constituents. One of the limitations of BAs is their poor oral bioavailability. The aim of the study was to prepare solid lipid particles of Boswellia serrata extract (SLBSP) to enhance the bioavailability of BAs. Methods The pharmacokinetic profile of BAs was studied in 10 healthy human volunteers following a single oral dose of 333 mg of SLBSP. Pharmacokinetic blood samples were collected at 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 12 h post drug administration. Plasma KBA and AKBA levels were measured using a validated LC-MS/MS method. Pharmacokinetics parameters were estimated using Pheonix WinNonlin (Build 6.4.0.768) software. Results Ten healthy human volunteers were included and peak plasma concentration was achieved in 1.5 and 2.3 h for AKBA and KBA respectively. Maximum plasma concentration (C max) was 8.04 ± 1.67 ng/mL for AKBA and 23.83 ± 4.41 ng/mL for KBA whereas the corresponding area under the concentration-time curve (AUC) was 136.7 ± 56.77 ng/mL*h and 165.7 ± 24.5 ng/mL*h respectively. The elimination half-life (t 1/2) of AKBA and KBA was 6.8 ± 3.0 h and 2.45 ± 0.3 h respectively. Conclusions The SLBSP formulation of BSE showed enhanced oral bioavailability of BAs compared with historically reported data of unformulated BSE.

In continuation of our search for leads from medicinal plants against protozoal pathogens, we detected antileishmanial activity in polar fractions of a dichloromethane extract from Boswellia serrata resin. 11-keto-β-boswellic acid (KBA) could be isolated from these fractions and was tested in vitro against Leishmania donovani axenic amastigotes along with five further boswellic acid derivatives. 3-O-acetyl-11-keto-β-boswellic acid (AKBA) showed the strongest activity with an IC50 value of 0.88 µM against axenic amastigotes but was inactive against intracellular amastigotes in murine macrophages

Background: Osteoarthritis (OA) is a chronic disease that causes joint pain, stiffness, and swelling. The knee is the most affected joint in osteoarthritis. A common therapy that often used for osteoarthritis patients is NSAIDs, but previous study showed that satisfactory pain control cannot be achieved with NSAIDs alone so that additional analgesic therapy is needed. Some previous studies showed the extracts of Curcuma longa and Boswellia serrata were promising in reducing pain and do not cause serious side effects in osteoarthritis patients. Obejctive: to measure the effect of additional therapy Curcuma longa and Boswellia serrata to NSAIDs on functional activities in knee osteoarthritis patients. Methods: The type of this research is cross-sectional involving 71 patients. This study uses secondary data taken from previous RCT studies by completing questionnaires to determine the WOMAC score of osteoarthritis patients at Bethesda Hospital and Panti Rapih Hospital in Yogyakarta. The treatment used were CB extract (350 mg Curcuma longa and 150 mg Boswellia serrata) and NSAIDs (400 mg Ibuprofen or 50 mg sodium diclofenac). Data were analyzed statistically using the licensed SPSS program with the Wilcoxon test and the Mann-Whitney test. Results: The reduction of WOMAC scores was superior in the NSAIDs group with Curcuma longa and Boswellia serrata after being given therapy for 4 weeks but not significant (p=0.372). Conclusion: The giving of additional therapy Curcuma longa and Boswellia serrata to NSAIDs had the same effect as NSAIDs in increasing functional activities in osteoarthritis patients.

AbstractBoswellic acids constitute a group of unique pentacyclic triterpene acids from Boswellia serrata with multiple pharmacological activities that confer them anti-inflammatory and anti-tumoral properties. A subgroup of boswellic acids, characterized by an 11-keto group, elevates intracellular Ca2+ concentrations [Ca2+]i and causes moderate aggregation of human platelets. How different BAs and their mixtures in pharmacological preparations affect these parameters in activated platelets has not been addressed, so far. Here, we show that boswellic acids either antagonize or induce Ca2+ mobilization and platelet aggregation depending on defined structural determinants with inductive effects predominating for a B. serrata gum resin extract. 3-O-Acetyl-11-keto-β-boswellic acid potently suppressed Ca2+ mobilization (IC50 = 6 µM) and aggregation (IC50 = 1 µM) when platelets were activated by collagen or the thromboxane A2 receptor agonist U-46619, but not upon thrombin. In contrast, β-boswellic acid and 3-O-acetyl-β-boswellic acid, which lack the 11-keto moiety, were weak inhibitors of agonist-induced platelet responses, but instead they elicited elevation of [Ca2+]i and aggregation of platelets (≥ 3 µM). 11-Keto-β-boswellic acid, the structural intermediate between 3-O-acetyl-11-keto-β-boswellic acid and β-boswellic acid, was essentially inactive independent of the experimental conditions. Together, our study unravels the complex agonizing and antagonizing properties of boswellic acids on human platelets in pharmacologically relevant preparations of B. serrata gum extracts and prompts for careful evaluation of the safety of such extracts as herbal medicine in cardiovascular risk patients.

AbstractThe aim of the present study was to evaluate the wound healing potential and possible mechanism of action of the standardized extract of Boswellia serrata against the experimental model of diabetic foot ulcer. α-Boswellic acid was isolated from the standardized extract of B. serrata and characterized (HPLC, 1H-NMR, 13C-NMR, ESI-MS). Diabetes was induced in Sprague-Dawley rats by streptozotocin (55 mg/kg, i. p.), and wounds were created on the dorsal surface of the hind paw. B. serrata (100, 200, and 400 mg/kg, p. o.) was administered to the rats for 16 days. The HPLC analysis showed a single peak with a retention time of 12.51 min. The compound was identified with ESI-MS [M + Na]+ = 455.37 as α-boswellic acid. Treatment with B. serrata (200 and 400 mg/kg) significantly increased the rate of wound contraction via modulation of oxido-nitrosative stress and elevated the hydroxyproline level at the wound area. reverse transcription-PCR analysis revealed that streptozotocin-induced increases in TNF-α, interleukin-1β, interleukin-6, nuclear factor-kappa-light-chain-enhancer of activated B cells, and Bcl-2-associated X protein, and decreases in angiopoietin-1, Tie2, transforming growth factor beta 1, vascular endothelial growth factor, and collagen-1 mRNA expression were significantly inhibited by B. serrata. It also significantly reduced wound cellular necrosis as evaluated by flow cytometry using propidium iodide fluorescence intensity. Streptozotocin-induced histopathological alterations were also significantly ameliorated by B. serrata. In conclusion, standardized extracts of B. serrata exert its wound healing potential via orchestrating mechanisms, which include the inhibition of oxido-inflammatory markers (oxido-nitrosative stress, TNF-α, interleukins, and nuclear factor-kappa-light-chain-enhancer of activated B cells), increased collagen synthesis (hydroxyproline and collagen-1) and angiogenesis (Ang-1/Tie2), promoting growth factors (transforming growth factor beta 1 and vascular endothelial growth factor), and inhibition of apoptosis (Bcl-2-associated X protein) to accelerate wound healing in experimental delayed diabetic foot ulcer.

Background:The need for safe, effective pain management for osteoarthritis (OA) is important as the number of australian people with OA is expected to grow by 30% from year 2015 to year 2030. Extracts from Boswellia serrata and Curcuma longa are described to have anti-inflammatory and analgesic properties. Clinical studies have also reported efficacy for improving joint pain and stiffness and tolerability. A combination of Boswellia serrata and Curcuma longa formulated extracts might provide benefits in OA pain management.Objectives:To review the literature describing the efficacy, safety and bioavailability of a formulated Boswellia serrata extract enriched with boswellic acids and a Curcuma longa extract formulated with piperine for OA pain management.Methods:PubMed searches for studies reporting efficacy, safety, and/or bioavailability data for Boswellia and Curcumin formulations were conducted on 4 December 2020 with no publication date limitations.Results:For the enriched Boswellia formulation, two clinical studies in OA assessing efficacy and one preclinical bioavailability study were identified1,2,3. For the curcumin formulation, 2 clinical studies were identified4,5. Two double-blind, randomized, parallel, placebo-controlled studies (each N=60) demonstrated significant improvement in Western Ontario and McMaster Universities OA index (WOMAC) pain and stiffness subscale scores in patients with knee OA receiving the enriched Boswellia formulation (100mg/d): In the first study1, a 30-day treatment with enriched Boswellia, compared with placebo, significantly reduced WOMAC pain (−23.6; placebo, −5.6; P<0.0001) and stiffness (−18.8; placebo, −3.4; P=0.0014) scores. Improvement in pain visual analog scale (VAS) score was significant versus placebo at day 5 (P<0.05). In the second study2, A 90-day treatment with enriched Boswellia also significantly improved WOMAC pain (−31.1; placebo, −8.4; P<0.0001) and stiffness (−27.7; placebo, −9.9; P<0.0001) scores versus placebo; Of note, a significant reduction in pain score and functional ability was observed as early as day 7. For the curcumin/piperine formulation, piperine was added to increase the bioavailability of curcumin in humans as established in a comparative bioavailability and pharmacokinetic study4. The results obtained in his study demonstrates that piperine enhances the oral bioavailability of curcumin without side effects. Curcumin/piperine monotherapy (350-400mg curcumin TID) was also shown to significantly reduce WOMAC, VAS and Lequesne’s pain functional index (LPFI) compared to placebo in a randomized double-blind placebo-controlled parallel-group study (N=40)5. In a sub-study that measured inflammatory biomarkers (N=40), there is no significant difference in the magnitude of changes in the inflammatory biomarkers (IL-4, IL-6, hs-CRP, TNF-α, TGF-β and mean ESR between the curcuminoid treatment group and the placebo group (p>0.05)6.Conclusion:Enriched boswellic acid and curcumin/piperine formulations demonstrate efficacy and safety for suitable treatment option: both ingredients, often cited as natural alternatives to address OA pain and stiffness could be evaluated to explore the potential benefit as a formulated combination.References:[1]Vishal et al.

ABSTRACT Traditional herbal formulas used to treat inflammatory arthritis in China and India include Boswellia carterii or Boswellia serrata. They both contain boswellic acids (BAs) which have been shown to exhibit anti-inflammatory and antiarthritic properties. This study tests the hypothesis that mixtures of BAs derived from B. carterii have immunomodulatory properties. B. carterii plant resin obtained from China was prepared as an ethanol extract, and the presence of seven BAs was confirmed by column chromatography, high-performance liquid chromatography, and UV laser desorption/ionization tandem mass spectroscopy. The extract was then tested for its ability to alter in vitro production of TH1 cytokines (interleukin-2 [IL-2] and gamma interferon) and TH2 cytokines (IL-4 and IL-10) by murine splenocytes. Delivery of the resin extract using ethanol as a solvent resulted in significant cellular toxicity not seen with the addition of ethanol alone. By contrast, delivery of the resin extract using a sesame oil solvent resulted in a dose-dependent inhibition of TH1 cytokines coupled with a dose-dependent potentiation of TH2 cytokines. These results indicate that a purified mixture of BAs from B. carterii plant resin exhibits carrier-dependent immunomodulatory properties in vitro.

The paper discusses the results and substantiates the effectiveness of pharmacotherapy for osteoarthritis of the knee joints using a dietary supplement Cartilox, which includes five active substances (type II collagen peptide, Boswellia serrata extract, curcuminoids, piperine and hyaluronic acid).

As science and technology has developed, the manner by which drugs can be delivered has grown. This research explores an alternative method for the delivery of therapeutic compounds to the body. The basis of the study involves the application of traditional medicines on textiles. Boswellia Serrata Extract (B.S.E.) is a common traditional medicine used for curing body pains. The most common form of B.S.E. based products are creams that are applied directly to the skin. Experiments show that these creams were not suitable as a basis for applying to textile materials because the creams contain highly volatile compounds, which on drying the treated textile, post application, cause almost total loss of the B.S.E. The approach used was the application on textiles of a 'commercial' topical medicine applied as a cream for, where B.S.E. is a major constituent. Cotton woven fabric was padded with this cream and tested for washing and rubbing fastness. The presence of highly volatile substances in the topical cream resulted in a negligible amount of the medicine on the dried treated fabric. Another approach was used for the application of B.S.E. onto the textile substrate. A commercially available B.S.E. powder was applied to woven fabric using a pad mangle. Tests were carried out to validate the

Colorectal cancer (CRC) become a worldwide public health problem. In the previous studies, inflammation-linked carcinogenesis is well accepted concept and is often observed. Boswellia serrata resin has been used in India traditional medicine to treat a variety of inflammatory-related diseases. The most significant components of its supercritical CO2 extraction analysis by LC-MS/MS are boswellic acids including β-boswellic acid, acetyl-β-boswellic acid, 11-keto-β-boswellic acid and acetyl-11-keto-β-boswellic acid. Although boswellic acids have been shown to be potential anti-tumorigenesis phytochemicals, but their mechanisms involved are not clear. In the present study, we investigated the chemopreventive effects of a Boswellia serrata (BS) extract on azoxymethane/dextran sulfate sodium (AOM/DSS)-induced colon tumorigenesis in ICR mice. We found that the treatment with BS extract can restore the shortening of the colon length, enhance the survival rate and reduce the colonic tumor growth. Western blot and histological analysis revealed that dietary BS extract could markedly reduce the protein levels of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), mitogen-activated protein kinases (MAPKs) and nuclear expression of NF-κB. Furthermore, BS extract reduced cell proliferation via inhibiting phosphorylation level of Akt, GSK3β and downregulation of cyclin D1. In addition, we also observed the changes on colonic microbiota after fed with BS extract that enhanced the ratio of Clostridiales and decreased abundance of Bacteroidales in AOM/DSS-treated mice. These results suggest that dietary administration of BS extract may alleviate colonic tumorigenesis.
