Abstract

The studies were carried out to evaluate the constituents in the aerial part of Aconitum chiisanense (Ranunculaceae). From the butanol fraction of the methanol extract, kaempferol 3-O-β-glucopyranoside-7-O-(6-trans-caffeoyl)-β-glucopyranosyl-(1→2)-α-rhamnopyranoside (I), quercetin 3-O-β-glucopyranoside-7-O-(6-trans-caffeoyl)-β-glucopyranosyl-(1→2)-α-rhamnopyranoside (II), kaempferol 3-O-β-glucopyranoside-7-O-(6-trans-feruloyl)-β-glucopyranosyl-(1→2)-α-rhamnopyranoside (III), kaempferol 3-O-β-glucopyranoside-7-O-(6-benzoyl)-β-glucopyranosyl-(1→2)-α-rhamnopyranoside (IV), kaempferol 7-O-(6-trans)-caffeoyl)-β-glucopyranosyl-(1→2)-α -rhamnopyranoside (V), and kaempferol 7-O-β-glucopyranosyl-(1→2)-α-rhamnopyranoside (VI) were isolated and identified on the basis of their physicochemical and spectroscopic evidence (UV, IR, FAB(-)MS, 1H-NMR, 13C-NMR, 1H-1H COSY, HMQC and HMBC). New compounds I-VI were named chiisanin (I), chiiribanin (II), chiiribaconin (III), chiirin (IV), chiiricanin (V), and chiirirhamnin (VI), respectively.
