Abstract
Phytochemical investigation of the ethyl acetate extracts from root barks of Dictamnus dasycarpus led to the isolation of three new compounds, named as dasycarpusenester A (1), dasycarpusester B (2), dasycarpusacid (3). Their structures were elucidated as (2S)-4-(2,2-dimethyl-5-oxotetrahydrofuran-3-yl)-2-hydroxypent-3-enoic acid methyl ester (1), (2R)-4-(2,2-dimethyl-5-oxotetrahydrofuran-3-yl)-2-hydroxypent-3-anoic acid methyl ester (2), and (2S)-4-(2,2-dimethyl-5-oxotetrahydrofuran-3-yl)-2-hydroxypent-3-anoic acid (3), respectively, on the basis of modern spectroscopic methods and chemical analysis.
