posted on 2020-06-05, 08:25 authored by Qiang-Qiang Shi, Ya Gao, Jing Lu, Lin Zhou, Ming-Hua QiuTwo new triterpenoid-chromone hybrids, cimitriteromones H (1) and I (2), along with two known analogues (3, 4) were isolated from the phytochemical research on the n-butyl alcohol extracts of Actaea cimicifuga rhizomes. The new compounds were elucidated by spectroscopic experiments and chemical method. The cytotoxic activities of the isolated compounds were tested on A-549/Taxol cell line. Cimitriteromone I (2) showed cytotoxicity with IC50 value of 27.14 ± 1.38 μM comparable to positive control group cisplatin (IC50 value of 25.80 ± 1.15 μM).
