ABSTRACT


Phytochemical investigation of Lycium shawii Roem. & Schult provided fourteen compounds, including lyciumate (1), dehydrocostus lactone (2), costunolide (3), catechin(4), lyciumaside (5), emodin (6), emodin-8-O-β- D -glucoside (7), aloe-emodin (8), aloe-emodin-8-O-β- D -glucoside (9), aloe emodin-11- O -rhamnoside (10 ) , chrysophanol - 8 - O - D - glucoside (11), nonacosane-10-ol (12), betulinic acid (13) and β -sitosterol glucopyranoside (14). The compounds may be classified as three sesquiterpene lactones (1-3), two phenolic compounds (4 and 5), six anthraquinones (6-11), one long chain alcohol (12), one lupane-type triterpenoid (13) and a steroid (14). Compounds 237 and 9-12 are reported here for the first time as isolated from any species of Lycium as well as from the Solanaceae family while compounds 813 and 14 are reported to be found for the first time in the genus Lycium. All structural assignments were made by comparing the NMR spectral data of the pure isolates with that published in the quoted literature.
