摘要: A new limonoid, 17-(5-methoxy-2-oxofuran-3-yl)-28-deoxonimbolide(1), and a new C21 steroidal saponin, 2α, 4α-dihydroxy-pregn-5-en-16-one-3α-O-D-glucopyranoside(2), together with 11 known compounds were isolated from the methanol extract of the leaves of Azadirachta indica. The structures were elucidated by means of spectroscopic analysis and putative biosynthetic origins. All the compounds were evaluated for their antibacterial activities against six bacterial strains.
