Pedicularis L. Genus. Systematics, botany, phytochemistry, chemotaxonomy, ethnopharmacology, and other

In this review, the relevance of the plant species belonging to the Pedicularis L. genus has been considered from different points of view. Particular emphasis was given to phytochemistry and ethnopharmacology, since several classes of natural compounds have been reported within this genus and many of its species are well known to be employed in the traditional medicines of many Asian countries. Some important conclusions on the chemotaxonomic and chemosystematic aspects of the genus have also been provided for the first time. Actually, this work represents the first total comprehensive review on this genus

Nor-lignans. Occurrence in plants and biological activities. A review

In this review article, the occurrence of nor-lignans and their biological activities are explored and described. Nor-lignans have proven to be present in several different families also belonging to chemosystematically distant orders as well as to have many different beneficial pharmacological activities. This review article represents the first one on this argument and is thought to give a first overview on these compounds with the hope that their study may continue and increase, after this

Highlights in oleuropein aglycone structure

Oleuropein hydrolysis products, obtained both by endogenous beta-glucosidase and almond commercial one, were investigated by classic methodologies and by (HNMR)-H-1 experiments. We found that both presence and relative amount of the different compounds in the reaction mixture are strictly related to the used enzyme

Total synthesis of anthocyanidins via Heck reaction

Anthocyanidin moiety was obtained by cyclization of a 2-hydroxychalcone prepared by the Heck approach to the synthesis of flavonoids. 1-(3,4-dimethoxyphenyl)-prop-2-en-1-one has been used as a coupling partner along with o-acetoxyiodobenzene in the Heck reaction

A new efficient resveratrol synthesis

The (E)-3,4',5-trihydroxystilbene (resveratrol) was synthesised via Heck reaction in few steps and with an overall 70% yield. (C) 2002 Elsevier Science Ltd. All rights reserved
