Abstract

Based on an NMR-guided method, one new monoterpenoid glycoside (1) was isolated from Anhua dark tea, together with five known compounds (26). The structure of the new compound was determined as 3-(5,5-dimethyltetrahydrofuranyl)-1-buten-3-ol primeveroside, and trivially named anhuaterpenoside A (1), on the basis of detailed spectroscopic analyses, and acidic hydrolysis. Compound 1 exhibits cytotoxic activity against MDA-MB-231 and SH-SY5Y cell lines with IC50 value of 23.26 μM and 18.57 μM, respectively.
