Abstract

A new phenylpropanoid allopyranoside (1) and a new indolinone alkaloid (2) were isolated from the rhizomes of Actaea dahurica (syn. Cimicifuga dahurica). The structures of those two compounds were deduced as cimicifugaside F (1) and 3E,11E-(3-methyl-2-butenylidene acid)-2-indolinone-1-O-β-d-glucopyranoside (2) by detailed analysis of their MS, 1D and 2D NMR data and comparison with literatures. Additionally, the isolates were evaluated for their inhibitory effects on the production of NO by LPS-stimulated RAW 264.7 macrophages. © 2020 Informa UK Limited, trading as Taylor & Francis Group.
