New phenolic compounds of Acmella ciliata.

The phytochemical analysis of a butanolic fraction of Acmella ciliata Kunth. afforded a total of 15 hydrophilic compounds. Seven flavonol 3-O-glycosides were isolated, including two new natural products, quercetin-3-O-(3-O-acetyl-beta-D-glucuronopyranoside) and quercetin-3-O-(2- O-acetyl-alpha-L-rhamnopyranosyl-(1--> 6)-beta-D-glucopyranoside). Furthermore, a variety of caffeoylquinic acid derivatives could be identified using ESI-MS and NMR-spectroscopy. Georg Thieme Verlag KG Stuttgart.New York.
