A panel of lipases was screened for the selective acetylation and alcoholysis of silychristin and silychristin peracetate, respectively. Acetylation at primary alcoholic group (C-22) of silychristin was accomplished by lipase PS (Pseudomonas cepacia)

Phenylpropanoid glucosides (PPGs) are naturally occurring and bioactive phenolic derivatives, largely distributed in plants. In this work different PPGs have been chemically or enzymatically synthesized from the lignols coniferyl and p -coumaryl alco

The laccase-catalyzed oxidation of piceid, the 3-beta-D-glucopyranosyl derivative of the stilbenic phytoalexin resveratrol, allowed isolation of the corresponding beta-5 like trans-dehydrodimer in good yield (45%) avoiding chromatography. This compou

Resveratrol is widely known as an antioxidant and anti-inflammatory molecule. The present study first reports the effects of trans-δ-viniferin (TVN), a dimer of resveratrol, on human erythrocytes. The antioxidant activity of TVN was tested using in

Dimerization of phenolic compounds can potentially enhance their biological (antioxidant) activity. We present here the selective oxidative dimerization of several flavonolignans from Silybum marianum seed extract, namely, silybin A (1a), silybin B (
