Abstract
Twenty-two compounds were isolated from the flowers of Scabiosa tschilliensis. Their structures were identified by spectroscopic methods as octacosanol (1), stearic acid (2), β-sitosterol (3), oleanolic acid (4), apigenin (5), luteolin (6), daucosterol (7), kaempferol-3-O-β-D-6-O-(p-hydroxycinnamoyl) -glucopyranoside (8), kaempferol-3-O-β-D- (3, 6-di-p-(hydroxycinnamoyl) -glucopyranoside (9), apigenin-7-O-β-D-glucopyranoside (10), luteolin-4'-O-β-D-glucopyranoside (11), apigenin-7-O-rutinoside (12), luteolin-7-O-β-D-glucopyranoside (13), apigenin-4'-O-β-D-glucopyranoside (14), caffeic acid methyl ester (15), loganin (16), adenosine (17), luteolin-6-C-β-D-glycopyranosyl (18), sweroside (19), sylvestrosides I (20), sylvestrosides II (21), urceolide (22). Among them, compounds 1, 2, 7-9, 12, 15, 17-18, 20-22 were isolated from the genus Scabiosa for the first time, and compounds 1-4, 6-9, 11-12, 14-22 were isolated from this plant for the first time. 13C-NMR data of 22 were reported for the first time.
