Abstract

Three new stigmastane-type steroid glucosides, vernonioside A4, B2 and B3, as well as the aglycone of A4 were isolated from Vernonia amygdalina, a possible medicinal plant used by wild chimpanzees. Vernonioside A4 and its aglycone were bitter but others were not.

    The biogenetically related compounds 2–12 were determined to be the same as that of 1, 5 and 6 due to their identical ECD curves. The structures of known compounds, Vernonioside B2 aglycone (13) [25], VE-2 (14) [26], vernoamyoside E (15) [27], VE-1 (16) [28] and vernoniacum B (17) [29] were elucidated by comparing their NMR data to the reported literatures. Except for compound 1 and 3, the tautomerism phenomenon were also occurred in compounds 4–6, 12–17 on account of the hemiacetal fragments presented at C-21 or C-28.

    The 1H NMR spectrum showed the characteristic signal of an anomeric proton as a doublet at δH 4.41 (H-1′). The large coupling constant (J = 7.8 Hz) between H-1′ and H-2′ supported the beta-linkage of the sugar moiety [15]. The typical carbon signal δC 100.7 has a correlation of δH 4.41 (1H, d, H-1′), and the HMBC correlation from H-1′ (δH 4.23) to C-3 (δC 76.2) indicated that the β-D glucosyl group was connected to C-3.
