“…The EtOAc layer was subjected to vari- ous column chromatographies to yield a new tirucallane-type triterpenoid, sweitenitol (1). In addition, 15 known compounds were identified to be agladupol D (2), [7] 21α-meliandiol (3), 21α-methylmeliandiol (4), [8] protoxylocarpins F (5), [ 9 ] methyl 1α-acetoxy-6,8α,14β,30β-tetrahydroxy-3-oxo-[3.3.1 10,2 .1 1,4 ]-tricyclomeliac-7-oate (6), [10] seneganolide (7), [11] methyl 1α-acetoxy-2β,3α,6,8α,14β-pentahydroxy-[4.2.1 10,30 .1 1,4 ]-tricyclomeliac-7-oate (8), [10] methyl 1α-acetoxy-3β,6,8α,-trihydroxy-2α-methoxy-2β,14β-epoxy-[4.2.1 10,30 .1 1,4 ]-tricyclomeliac-7-oate (9), [12] 1-acetylkhayanolide B (10), [13] (+)-catechin (11), aromadendrin (12), [14] ivorenolide A (13), [15] 24-methylenecycloartanol (14), [16] β-sitosterol (15), and daucosterol (16) by comparison of their spectroscopic data and physicochemical properties with data reported in the literatures.…”
