Over the past 27 years numerous clinical studies have found a linkages with the ANTIOXIDANTS in particular, the POLYPHENOLS, RESVERATROL, CATECHINS, QUERCERTIN and ANTHOCYANDINS in red wine and reduced incidences of cardiovascular disease. However, the alcohol in wine limits the benefits of wine. Studies have shown that zero alcohol red wine and red wine extract which contain the same ANTIOXIDANTS including POLYPHENOLS, RESVERATROL, CATECHINS, QUERCERTIN and ANTHOCYANDINS has the same is not more positive health benefits. The following literature review details some of the most recent positive health benefits derived from the ANTIOXIDANTS found in red wine POLYPHENOLS: RESVERATROL, CATECHINS, QUERCERTIN and ANTHOCYANDINS. The positive polyphenolic antioxidant effects of the polyphenols in red wine include: • Cardio Vascular Health Benefits • Increase antioxidants in the cardiovascular system • Assisting blood glucose control • Skin health • Bone Health • Memory • Liking blood and brain health • Benefits -
Molecular Cloning and Functional Characterization of an O-Methyltransferase Catalyzing 4 -O-Methylation of Resveratrol in Acorus

Although the biosynthetic pathway of resveratrol has been fully elucidated, the characterization of resveratrol-specific O-methyltransferases remains elusive. In this study, we used RNA-seq analysis to identify a putative aromatic O-methyltransferase gene, AcOMT1,inAcorus calamus. Recombinant AcOMT1 expressed in Escherichia coli showed high 40-O-methylation activity toward resveratrol and its derivative, isorhapontigenin. We purified a reaction product enzymatically formed from resveratrol by AcOMT1 and confirmed it as 40-O-methylresveratrol (deoxyrhapontigenin). Resveratrol and isorhapontigenin were the most preferred substrates with apparent Km values of 1.8 mM and 4.2 mM, respectively. Recombinant AcOMT1 exhibited reduced activity toward other resveratrol derivatives, piceatannol, oxyresveratrol, and pinostilbene. In contrast, re- combinant AcOMT1 exhibited no activity toward pterostilbene or pinosylvin. These results indicate that AcOMT1 showed high 40-O-methylation activity toward stilbenes with non-methylated phloroglucinol rings. -

Kiselev * Laboratory of Biotechnology, Federal Scientific Center of the East Asia Terrestrial Biodiversity, FEB RAS, 690022 Vladivostok, Russia; [email protected] (A.R.S.); [email protected] (A.S.D.); [email protected] (A.P.T.) * Correspondence: [email protected]; Fax: +7-4232-310193 Abstract: Grapes and wines represent the most important source of edible stilbenes and other phenolic metabolites, which demonstrate a wide range of valuable biological activities. However, there is no information about the profile and content of phenolic compounds in Russian wines. We firstly analyzed phenolics (stilbenes, phenolic acids, and flavonols) in some representatives of Russian wines, including eleven red and seven white Russian wines from Fanagoria, Krasnodarsky Territory. The Russian red wines contained six stilbenes (trans-resveratrol, cis-resveratrol, trans-, cis-piceid, trans-piceatannol, d-viniferin), while the white wines contained only five stilbenes (cis- resveratrol, trans-, cis-piceid, trans-piceatannol, trans-resveratrol). More than a half of the total stilbenes in the wines (65% of all stilbenes) were presented by trans-piceid and cis-piceid, while trans-resveratrol reached 16% of all the stilbenes. The red wines also contained six phenolic acids and six flavonols, while the white wines contained six phenolic acids and only three flavonols.

Abstract: Stilbenes or stilbenoids, major polyphenolic compounds of the bark of Norway spruce (Picea abies L. Karst), have potential future applications as drugs, preservatives and other functional ingredients due to their antioxidative, antibacterial and antifungal properties. Stilbenes are photosen- sitive and UV and fluorescent light induce trans to cis isomerisation via intramolecular cyclization. So far, the characterizations of possible new compounds derived from trans-stilbenes under UV light exposure have been mainly tentative based only on UV or MS spectra without utilizing more detailed structural spectroscopy techniques such as NMR. The objective of this work was to study the stability Citation: Latva-Mäenpää, H.; Wufu, of biologically interesting and readily available stilbenes such as astringin and isorhapontin and R.; Mulat, D.; Sarjala, T.; Saranpää, P.; their aglucones piceatannol and isorhapontigenin, which have not been studied previously. -
Resveratrol: Twenty Years of Growth, Development and Controversy
Invited Review Biomol Ther 27(1), 1-14 (2019) Resveratrol: Twenty Years of Growth, Development and Controversy John M. Pezzuto* Arnold & Marie Schwartz College of Pharmacy and Health Sciences, Long Island University, Brooklyn, NY 11201, USA Abstract Resveratrol was first isolated in 1939 by Takaoka fromVeratrum grandiflorum O. Loes. Following this discovery, sporadic descrip- tive reports appeared in the literature. However, spurred by our seminal paper published nearly 60 years later, resveratrol became a household word and the subject of extensive investigation. Now, in addition to appearing in over 20,000 research papers, resveratrol has inspired monographs, conferences, symposia, patents, chemical derivatives, etc. In addition, dietary supple- ments are marketed under various tradenames. Once resveratrol was brought to the limelight, early research tended to focus on pharmacological activities related to the cardiovascular system, inflammation, and cancer but, over the years, the horizon greatly expanded. Around 130 human clinical trials have been (or are being) conducted with varying results. This may be due to factors such as disparate doses (ca. 5 to 5,000 mg/day) and variable experimental settings. Further, molecular targets are numerous and a dominant mechanism is elusive or nonexistent. In this context, the compound is overtly promiscuous. Nonetheless, since the safety profile is pristine, and use as a dietary supplement is prevalent, these features are not viewed as detrimental. Given the ongoing history of resveratrol, it is reasonable to advocate for additional development and further clinical investigation. Topical preparations seem especially promising, as do conditions that can respond to anti-inflammatory action and/or direct exposure, such as colon cancer prevention.
