“…From the methanol extract of S. staminea, we isolated the new triterpenoid, 3b,11a,21a-trihydroxyurs-12-ene (1), together with three flavones apigenin (2), luteolin (3), apigenin 7-O-glucoside (4), and sitosterol 3b-D-glucoside (5). The acetone extract yielded the two sesquiterpenes spathulenol (6) [4], and caryophyllene oxide (7) [5], the two steroids b-sitosterol (8) and stigmast-4-en-3-one (9) [6], the triterpenoid oleanolic acid 3b-acetate (10) [7], and the six diterpenes, ferruginol (11), taxodione (12) [8], microstegiol (13) [9], manoyloxide (14) [10],1-oxo-salvibretol (15) [9], cryptojaponol (16) [11] and the flavone apigenin 7,4¢-methyl ether (17).…”
