Background: Cinnamomum porrectum (C. porrectum) is an aromatic medicinal plant from southern Thailand. While many Cinnamomum species demonstrate medicinal properties such as anti-inflammatory effects, some species are known to contain safrole, a group 2B carcinogen. Although the leaves of C. porrectum are used to produce herbal tea, there is no scientific data to support its properties as a functional food or any guarantee of its safety.Objective: To determine the effect of blanching before drying of C. porrectum leaves on their safrole content, phenolic profile, total phenolic content (TPC), and total flavonoid content (TFC), antioxidant and anti-inflammatory activities were compared to leaves dried with hot air.Methods: In the first part of the study, the leaves were dried in three conditions: freeze dried (F), hot air dried at 60 oC (C), and blanched for 60 seconds at 100 oC (B) before being dried at 60 oC until the moisture content reached 5-7% and then were ground and sieved to make powders. The F, C, and B were extracted by methanol and redefined as FM, CM, and BM, for the determination of their chemical constituents by GC-MS using C. porrectum wood oil (CWO) as the safrole standard. In the second part of the study, the C and B powders were analyzed for their proximate composition and were also used to make herbal tea infusions (CT and BT respectively) which were analyzed for their phenolic profile, TPC, TFC, antioxidant activities, cytotoxicity, and anti-inflammatory activity in RAW 264.7 cells.Results: Significantly decreased safrole contents of 89% and 82% were found in the BM sample when compared with CM and FM respectively. The CT and BT had similar phenolic profiles but different contents. The TPC, TFC, ABTS, and FRAP activities, in addition to cell viability and the nitric oxide inhibition of BT were higher than that of CT.Conclusion: The results demonstrate how blanching C. porrectum leaves before drying can decrease the safrole content when compared to freeze dried and hot air-dried leaves, thereby leading to a decrease of cytotoxicity in RAW 264.7 cells. Additionally, BT demonstrated a more intense phenolic profile, TPC, ABTS, and FRAP compared with the un-blanched control sample.Keywords: C. porrectum, freeze drying, hot air drying, blanching before drying, safrole, RAW 264.7 cells.

Leaves of C. porrectum are rich in essential oils containing monoterpenes, sesquiterpenes and aromatic compounds, but the molecular mechanism of terpenoid biosynthesis in C. porrectum is still unclear. In this paper, the differences in the contents and compositions of terpenoids among three chemotypes were analyzed using gas chromatography mass spectrometry (GC/MS). Furthermore, the differential expression of gene transcripts in the leaf tissues of the three C. porrectum chemotypes were analyzed through a comparison of full-length transcriptomes and expression profiles. The essential oil of the three C. porrectum chemotypes leaves was mainly composed of monoterpenes. In the full-length transcriptome of C. porrectum, 104,062 transcripts with 306,337,921 total bp, an average length of 2944 bp, and an N50 length of 5449 bp, were obtained and 94025 transcripts were annotated. In the eucalyptol and linalool chemotype, the camphor and eucalyptol chemotype, and the camphor and linalool chemotype comparison groups, 21, 22 and 18 terpene synthase (TPS) unigenes were identified respectively. Three monoterpene synthase genes, CpTPS3, CpTPS5 and CpTPS9, were upregulated in the eucalyptol chemotype compared to the linalool chemotype and camphor chemotype. CpTPS1 was upregulated in the camphor chemotype compared to the linalool chemotype and the eucalyptol chemotype. CpTPS4 was upregulated in the linalool chemotype compared to the camphor chemotype and the eucalyptol chemotype. Different unigenes had different expression levels among the three chemotypes, but the unigene expression levels of the 2-C-methyl-D-erythritol 4phosphate (MEP) pathway were generally higher than those of the mevalonate acid (MVA) pathway. Quantitative reverse transcription PCR(qRT-PCR) further validated these expression levels. The present study provides new clues for the functional exploration of the terpenoid synthesis mechanism and key genes in different chemotypes of C. porrectum.

Background: C. porrectum leaves, one kind of Cinnamomum family, has recently been used to produce a locally herbal tea. Although C. porrectum essential oil and aqueous extract have been reported to have some biological activities, including antioxidant, antimicrobial, and anti-inflammatory activities, there is no scientific data using the blanching process for the production of herbal tea. Therefore, this experiment aimed to study the effect of hot water blanching before drying process on microstructure, nutrition content of the tea powder, TPC, TFC, antioxidant activities of infusion, as well as the phenolic profile of the extract.Objective: To determine effect of hot water blanching process on nutritional value, microstructure, phenolic profile, and antioxidant activity of the C. porrectum herbal tea.Methods: The C. porrectum leaves were divided into 2 groups; control (un-treated) and blanched before dried for herbal tea processing. The fresh leaves and the powders of control and blanched leaves were checked for proximate composition and chlorophyll contents, in addition to color value. The powders were determined microstructure by SEM. The infusions were determined to have color value and total extractable phenolic and flavonoid contents, as well as antioxidant activities. The hydrolyzed extracts of freeze dried infusion were subjected to identify phenolic profile by HPLC. Results: The blanched tea powder yielded a percentage of fat and protein contents higher than un-treated due to easier extraction because of the bigger pore size found in microstructure. Chlorophyll content of blanched was decreased compared with the control sample. However, it was found that blanching could greater maintain green color of both powder and infusion. Additionally, blanching helped increased TPC, TFC extractability, and antioxidant activities in all assays except metal chelating property. Based on retention time and peak profile determined by using HPLC, it was found that both control and treated extracts consisted of similar main phenolic and flavonoid compounds however, only kaempferol was found in un-treated. Moreover, hydrolyzed blanched extract showed a higher intensity of 2 unknown compounds than un-treated. Though un-treated provided a higher intensity of pyrogallol, gallic acid, and cinnamic acid, the blanched exhibited a higher intensity of caffeic acid, protocatechuic acid, p-coumaric acid, and rutin. Conclusion: Blanching before drying expanded pore size of dried leaves, increased yield extractability, maintained color value, chlorophylls and increased TPC and TFC which related to antioxidant activities. Blanched extract provided higher intensity of some phenolic compounds than un-treated.Keywords: Cinnamomum porrectum, blanching process, SEM, HPLC

Maximum assimilation rate under saturating light level, leaf nitrogen and chlorophyll content and specific leaf mass were measured in forest plants grown under a range of canopy openness. Seedlings from three tree species co-occurring in damar agroforest (Sumatra) were examined: Shorea javanica, Lansium domesticum and Cinnamomum porrectum. A shrub species, Piper hispidum, growing in a different location was also investigated. All species showed pronounced differences in maximum photosynthetic potential when grown under different canopy openness. All tree seedlings showed an increase in maximum assimilation rate (Amax) with canopy openness (CO) until a certain threshold was reached. This saturation threshold varied between species. A steady increase in the maximum assimilation rate over the entire range of canopy openness explored was found only for Piper. Correlation between leaf nitrogen content and Amax was usually highest when expressed on a per unit area basis. However the overall correlation was poor whether expressed per unit mass or per unit area when all species were pooled together questioning the universality of the relationship between both quantities. Potential photosynthetic nitrogen use efficiency, defined as the amount of CO2 uptake per unit leaf nitrogen under saturating light level, was highest in Cinnamomum, supposedly the most light-demanding species, and lowest in Lansium, the understorey specialist.

This study aimed to document (1) the Batak people’s knowledge of the use of medicinal plants for steam-bathing, (2) the preparation and operation of steam-bathing, and (3) the benefits of steam-bathing. To attain these objectives, data were collected by using ethnobotanical survey and interview methods. The survey was conducted in Kabanjahe and Berastagi traditional markets, in Kaban Tua village, and in Tanjung Julu village. The participants for the interview were nine medicinal plants traders, nine midwives, and 32 mothers. The basic principle of steam-bathing by the Batak people is based on thermotherapy and aromatherapy. A total of 59 species (belonging to 37 genera and to 25 families) have been documented as medicinal plants for their use as steam-bathing materials by the Batak people. The traders, midwives and mothers are all aware of the benefits of steam-bathing. Gaultheria leucocarpa Blume and Cinnamomum porrectum (Roxb.), the species that produce distinctive aromas and reduce pain, would be interesting to study for their phytochemical and pharmacological properties.

Diabetic neuropathy is a nerve damaging microvascular complication which is a result of long term diabetes contracted by more than 50% of diabetic individuals. It is responsible for pain, infection, numbness, foot ulceration and limb amputations. The cases of diabetes have risen exponentially in all income countries across the globe. As per the current treatment options available, pain management by physical therapy, diet control and certain drugs have been approved. But these drugs come with certain side effects such as blurry vision, headaches, sleep deprivation, nausea, hot flushes etc. along with display of certain mental side effects. To avoid these, certain natural compounds can be used to inhibit multiple pathways involved in diabetic neuropathy progression and do not show excessive side effects. Thus, with the help of in-silico methods, pharmacophore models of FDA approved drugs were generated and a list of natural compounds were curated which was then validated by docking and 2D visualization was done. 2,3-Dimethylbenzoic acid obtained from Cinnamomum porrectum was found out to be the best docked phytochemical against calcium channel as compared to FDA approved drugs. Cinnamomum porrectum is currently being used in Indian medicinal practices as antirheumatic agent. Thus, it can be used as a substitute for attenuating neuropathic pain.
