Two new flavonol glycosides from Sarcopyramis bodinieri var. delicate.
Detailed chemical investigation of the herb Sarcopyramis bodinieri var. delicate resulted in the isolation of two new flavonol glycosides, namely, isorhamnetin-3-O-(6''-OE-feruloyl)-beta-D-glucopyranoside (1) and isorhamnetin-3-O-(6''-O-E-feruloyl)-beta-Dgalactopyranoside (2). In addition, four known compounds, quercetin-3-O-(6''-acetyl)-beta-Dglucopyranoside (3), isorhamnetin-3-O-(6''-acetyl)-beta-D-glucopyranoside (4), quercetin-3-O-(6''-O-E-p-coumaroyl)-beta-D-glucopyranoside (5), and isorhamnetin-3-O-(6''-O-E-pcoumaroyl)-beta-D-glucopyranoside (6) were obtained. The structures of the new isolates were determined by extensive spectroscopic analysis.
