Laccase‐Catalyzed Dimerization of Piceid, a Resveratrol Glucoside, and its Further Enzymatic Elaboration

Advanced Synthesis & Catalysis, 2015
AbstractThe laccase‐catalyzed oxidation of piceid, the 3‐β‐D‐glucopyranosyl derivative of the stilbenic phytoalexin resveratrol, allowed isolation of the corresponding β‐5 like trans‐dehydrodimer in good yield (45%) avoiding chromatography. This compound was then submitted to the action of a small library of commercially available hydrolases. While the

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2003
To improve a RP-HPLC method of determining piceid in commercial Rhizoma Polygoni Cuspidati.HPLC method was used, with C18 column (250 mm x 4.6 mm), a mixture of CH3CN-H2O (20:80) as the mobile phase, and detecting wavelength 303 nm.The linear range was 0.0066-0.0792 microgram.microL-1, r = 0.9999 (n = 5). The average recovery rate was 98.5% and RSD was

Biotrasformation of piceid to resveratrol by a beta-glucosidase from Rhodotorula spp.

2009
Resveratrol (3,4?,5-trihydroxystilbene) is a phenolic compound produced by many spermatophytes, including grapevines. Resveratrol possesses a wide range of pharmacological properties that may account for its possible cardioprotective action, including the inhibition of low-density lipoprotein oxidation, inhibition of smooth muscle cell proliferation ...
