Stilbene glycoside gallates and proanthocyanidins from Polygonum multiflorum
TLDR
Two new stilbene glycoside gallates proanthocyanidins have been isolated from Polygonum multiflorum as discussed by the authors and were shown to be 2″-3″-O-monogalloyl esters of 2,3,5,4′-tetrahydroxystilbinene 2-Oβ-β-d -glucopyranoside.About:

A Review of Macromolecular Organic Compounds That Comprise Living Organisms and Their Role in Kerogen, Coal, and Petroleum Formation
J.W. de Leeuw,Claude Largeau +1 more
TL;DR: It is generally accepted that the formation of kerogens is the result of the so-called depolymerization-recondensation pathway (Tissot and Welte, 1984; Durand, 1980) as discussed by the authors.

Traditional usages, botany, phytochemistry, pharmacology and toxicology of Polygonum multiflorum Thunb.: A review
TL;DR: A systematic review of the literature on Polygonum multiflorum was performed using several resources, including classic books on Chinese herbal medicine and various scientific databases, to provide comprehensive information on the botany, traditional uses, phytochemistry, pharmacological research and toxicology of this plant.
Book ChapterDOI
Flavans and proanthocyanidins
TL;DR: Haslam as discussed by the authors summarized the historical developments in the chemistry and biochemistry of this important and complex group of plant phenolics and discussed their relationship with condensed tannins and aspects of their characteristic chemical and spectroscopic properties.

Natural products as photoprotection
Nisakorn Saewan,Ampa Jimtaisong +1 more
TL;DR: A number of natural products derived from propolis, plants, algae, and lichens that have shown potential photoprotection properties against UV radiation exposure‐induced skin damage are summarized.
Journal ArticleDOI
Structure and antiherpetic activity among the Tannins
TL;DR: The results indicate that the activities of hydrolysable tannins were dependent on the number of galloyl or hexahydroxydiphenoyl groups and those of condensed ones on the degree of condensation.

Plant proanthocyanidins. Part I. Introduction; the isolation, structure, and distribution in nature of plant procyanidins
TL;DR: In this paper, the isolation and determination of structure of some plant procyanidins in their free phenolic forms are described, and the distribution of procyclanidin in the tissues of twentynine plant species has been examined and the biogenetic implications of this study are briefly discussed.

Phytochemistry of proanthocyanidins
TL;DR: Procyanidin A from Aesculus hippocastanum differs from the B type procyanin in that it is difficultly soluble in water, gives a higher yield of cyanidin when heated in butanolic HCl and the production of cyanide continues beyond the 2-hour period sufficient for maximum production in the case of B-type procyaneidin this paper.
