Resveratrol and piceid isomers concentrations in grapevine shoots, leaves, and tendrils [PDF]

open access: yesHorticultural Science, 2016
The objective of this study was to evaluate the levels of cis- and trans-isomers of resveratrol and piceid contained in the shoots, leaves and tendrils of six grapevine varieties and three locations processed under two different drying conditions.

Optimized Ultrasound-Assisted Extraction of Phenolic Compounds from Polygonum cuspidatum [PDF]

open access: yesMolecules, 2013
In this study the phenolic compounds piceid, resveratrol and emodin were extracted from P. cuspidatum roots using ultrasound-assisted extraction. Multiple response surface methodology was used to optimize the extraction conditions of these phenolic ...

Inhibitory Effects of Resveratrol and Piceid against Pathogens of Rice Plant, and Disease Resistance Assay of Transgenic Rice Plant Transformed with Stilbene Synthase Gene [PDF]

open access: yesResearch in Plant Disease, 2013
Resvestrol has been known to inhibit bacterial and fungal growth in vitro, and can be accumulated in plant to concentrations necessary to inhibit microbial pathogens. Hence, stilbene synthase gene has been used to transform to synthesize resveratrol in

Chocolate and cocoa: New sources of trans-resveratrol and trans-piceid [PDF]

open access: yesFood Chemistry, 2006
trans-Resveratrol and trans-piceid were found for the first time in dark chocolate (at least 0.4 ppm trans-resveratrol and 1 ppm trans-piceid) and cocoa liquor (at least 0.5 ppm trans-resveratrol and 1.2 ppm trans-piceid). Because these compounds are highly sensitive to light, a specific extraction procedure was required to recover them, involving ...

Antioxidant properties of resveratrol and piceid on lipid peroxidation in micelles and monolamellar liposomes [PDF]

open access: yesBiophysical Chemistry, 2008
The antioxidant activities of trans-resveratrol (trans-3,5,4'-trihydroxystilbene) and trans-piceid (trans-5,4'-dihydroxystilbene-3-O-beta-D-glucopyranoside), its more widespread glycosilate derivative, have been compared measuring their inhibitory action on peroxidation of linoleic acid (LA) and the radical scavenging ability towards different free ...

Constitutive Accumulation of cis -piceid in Transgenic Arabidopsis Overexpressing a Sorghum Stilbene Synthase Gene [PDF]

open access: yesPlant and Cell Physiology, 2006
Sorghum SbSTS1 was the first example of a stilbene synthase gene in monocots. Previously, we demonstrated that the gene was involved in defense responses. To examine its biochemical function in planta, SbSTS1 was overexpressed in transgenic Arabidopsis.
