Ginkgo biloba (Ginkgoaceae), well-known as the oldest living plant species and often referred to as a “living fossil,” is a famous medicinal plant that has been used in multiple countries to improve numerous illnesses, including anxiety, dementia, peripheral artery disease, and eye problems. We conducted a phytochemical exploration of G. biloba fruit, commonly consumed as a functional food as part of an ongoing natural product chemical research for the discovery of bioactive phytochemicals with novel structures. The natural product chemical analysis of the methanol extract of G. biloba fruit using column chromatography and high-performance liquid chromatography separation under the guidance of a liquid chromatography–mass spectrometry (LC/MS)-based analysis identified six phenylpropanoid glycosides (1–6), including one new compound, ginkgopanoside (1). The structures of the isolated compounds were elucidated by nuclear magnetic resonance spectroscopic data and LC/MS analysis, and the absolute configuration of compound 1 was established by chemical reactions followed by the application of Snatzke’s method. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activities of the isolated compounds 1–6 and the aglycone 1a of 1 were evaluated, and we found that compounds 1–5 exhibited antioxidant activities with IC50 values in the range 32.75–48.20 μM, while the aglycone 1a exhibited greater radical scavenging activity (IC50 = 5.23 μM) comparable to that of ascorbic acid (IC50 = 2.54 μM), a positive control, implying that the present of glucose may decrease the DPPH scavenging activity. These findings provide experimental information that the active phenylpropanoid glycosides could represent natural antioxidants for use in pharmaceuticals and functional foods.

The aim of this research was to investigate the phytochemistry of two species Sanicula europaea and Teucrium davaeanum which are traditionally used in treatment of wounds. Four compounds were isolated from the 80% methanolic extract of S. europaea; bis-(2-ethylhexyl) phthalate (1), palmitic acid (2), rosmarinic acid (3), saniculoside N (4). Compounds 1 and 2 were isolated for the first time from this species. The structure elucidation of the isolated compounds was on the basis of 1D, 2D NMR spectroscopy and mass spectrometry measurements. Two compounds were isolated from the crude glycosides extract of T.davaeanum; 6 is a phenylethanoid glycoside and 8 is an iridoid glycoside, from the data available these may be new compounds for which the names davaeanuside A and davaeanuside B are proposed respectively." The total polyphenol content of S. europaea L, T. davaeanum leaves-flowers and T. davaeanum stem were found to be 5.0, 1.20 and 0.65 mg per 100 mg dried plant material respectively. A study of the antioxidant activity of the 50 % ethanol extracts of S. europaea and T. davaeanum showed that on a mg/mg basis S. europaea and T. davaeanum have approximately 5%, 8 % antioxidant capacity of Trolox respectively. A study of the cytotoxic activity of davaeanuside A (6), iridoid glycoside (7), davaeanuside B (8) and saponin compound (10) isolated from the crude glycosides extract of T. davaeanum revealed that saponin compound (10) inhibited the growth of Hela cells by 50 % at 50 μg/ml, P< 0.001, but the other compounds did not show activities against the tested cell lines at 100 μg/ml. The results of this work provide some basis for the traditional use of these species in the treatment of wounds.

L’identificazione di antiossidanti naturali per un’efficace fotoprotezione e per la soppressione di reazioni infiammatorie nella pelle è oggi uno dei principali interessi dell’indagine dermatologica. I presenti risultati suggeriscono fortemente che i fenilpropanoidi glicosidi (PPGs), forsythoside B, echinacoside, verbascoside e parzialmente anche campneoside I, possano rappresentare sostanze naturali di particolare interesse per la dermatologia per la protezione della pelle contro lo stress ossidativo indotto dall’ambiente e contro gli insulti infiammatori. Infatti, mediante PCR real time, è emerso che, in una linea cellulare di cheratinociti umani (HaCaT), questi composti inducono l’espressione di un importante gene detossificante di fase II, l’eme ossigenasi-1 (HO-1), in maniera dose e tempo dipendente. Per aumentare l’espressione del gene HO-1 erano necessarie 24 ore di trattamento con i PPGs. Una singola somministrazione di verbascoside, forsythoside B ed echinacoside (200 µM) alle colture cellulari causava un ulteriore aumento nella quantità di trascritto per l’HO-1 dopo 48 e 72 ore, mostrando che questi PPGs presentavano effetti con un inizio tardivo ma che perduravano a lungo. Inoltre, abbiamo dimostrato, mediante analisi di western blot, che l’aumento dell’mRNA per l’HO-1 da parte dei PPGs potrebbe dipendere dall’aumento dei livelli proteici nucleari dell’attivatore trascrizionale Nrf2 e dalla riduzione di quelli del repressore Bach1. In più, evidenze sperimentali suggeriscono che l’idrossitirosolo potrebbe essere il pricipale gruppo bioattivo dei PPGs dal momento che abbiamo dimostrato che l’idrossitirosolo, aggiunto da solo alle colture cellulari in quantità equimolari ai PPGs, era in grado sia di aumentare l’espressione genica dell’HO-1 sia di influire sui livelli proteici nucleari di Nrf2 e Bach1. La comprensione dei loro meccanismi molecolari sull’espressione dell’HO-1 potrebbe promuovere l’uso innovativo di questi composti in dermatologia per rallentare l’invecchiamento della pelle o alleviare malattie in cui lo stress ossidativo è una causa primaria.
The identification of natural antioxidants for effective photoprotection and suppression of inflammatory reactions in the skin is now a major concern for investigative dermatology. The present results strongly suggest that the phenylpropanoid glycosides (PPGs), forsythoside B, echinacoside, verbascoside and partially campneoside I, may represent natural substances of special dermatological interest for the protection of the skin from environmental induced oxidative stress and inflammatory insults. Indeed, using real time PCR, we found that, in a human keratinocytes cell line (HaCaT), these compounds induce the expression of an important detoxifying phase II gene, heme oxygenase-1 (HO-1), in a dose- and time-dependent manner. 24 hours of treatment with PPGs was required to increase HO-1 gene expression. A single administration of verbascoside, forsythoside B and echinacoside (200 µM) to cell cultures caused a further increase in the amount of HO-1 mRNA after 48 and 72 hours, showing that these PPGs had late onset but long lasting effects. Furthermore, we demonstrated, by western blot analyses, that the increase of HO-1 mRNA by PPGs might be dependent on the increase of Nrf2 transcription activator and the reduction of nuclear protein levels of Bach1 repressor. Moreover, experimental evidences suggest that hydroxytyrosol could be the major bioactive moiety of PPGs since we demonstrated that hydroxytyrosol, added alone to cell cultures in equimolar amounts to PPGs, was able to both increase HO-1 gene expression and affect Nrf2 and Bach1 nuclear protein levels. The understanding of their molecular mechanism on HO-1 expression could promote the innovative use of these compounds in dermatology to slow down aging or alleviate diseases in which oxidative stress is a primary cause.

This introductory chapter defines natural products as conditional metabolites, small molecules from secondary rather than primary metabolic pathways, noting how a few primary metabolites serve as building blocks for specific classes of up to hundreds of downstream conditional metabolites. The major classes of natural products, whose modes of biosynthesis are examined, include polyketides, ribosomal and nonribosomal peptides, isoprenoid scaffolds, purines and pyrimidines, phenylpropanoids, glycosides, and alkaloids. Three major categories of enzymes involved in complexity generation of natural product frameworks are oxygenases, S-adenosylmethionine (SAM)-dependent transferases that fragment SAM by two-electron and one-electron reaction manifolds, and pericyclases that catalyze concerted pericyclic transition states without any reaction intermediates.
