A New Ursane-Type Triterpene Fatty Acid Ester from the Whole Plants of Isodon serra
摘要
A new ursane-type triterpene fatty acid ester named 3β-O-hexacosanoyl-28-hydroxy-urs-12-ene (1) and two known triterpenes were obtained from the whole plants of Isodon serra (Maxim.) Kudo (Lamiaceae). The structure of the new compound was elucidated by extensive spectroscopic analysis. Compound 1 was evaluated for its antioxidant activity in vitro using the DPPH method.
