New steroidal glycoside ester and aliphatic acid from the fruits of Lycium chinense

J Asian Nat Prod Res. 2012;14(4):301-7. doi: 10.1080/10286020.2011.653346.

Abstract

Two new compounds stigmast-5-en-3β-ol-3-O-β-D-(2'-n-triacontanoyl) glucopyranoside (1) and 19,21-dimethyl triacont-17,22,24,26,28-pentaene-1-oic acid (2), along with the three known compounds n-tetracosanyl octadec-9-enoate (3), β-sitosterol, and β-sitosterol-3-O-β-D-glucoside, have been isolated from the methanol extract of Lycium chinense fruits. The structures of these phytoconstituents have been established on the basis of spectral data analysis and chemical reactions.
