title: Saponins from the flower buds of Buddleja officinalis.
abstract: Five new saponins, mimengosides C-G (1-5), were isolated from the flower buds of Buddleja officinalis along with five known compounds, namely, songaroside A, acteoside, phenylethyl 2-glucoside, echinacoside, and phenylethyl alcohol 8-O-beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranoside. The structures of 1-5 were elucidated using spectroscopic and chemical methods, and these compounds were evaluated for their inhibitory effects against HL-60 leukemia cells.
