title: New flavonoids from the aerial parts of Aconitum chiisanense.
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-beta-glucopyranoside-7- O-(6-trans-caffeoyl)-beta-glucopyranosyl-(1-->2)-alpha-rhamnopyranoside (I), quercetin 3- O-beta-glucopyranoside-7- O-(6-trans-caffeoyl)-beta-glucopyranosyl-(1-->2)-alpha-rhamnopyranoside (II), kaempferol 3- O-beta-glucopyranoside-7- O-(6-trans-feruloyl)-beta-glucopyranosyl-(1-->2)-alpha-rhamnopyranoside (III), kaempferol 3- O-beta-glucopyranoside-7- O-(6-benzoyl)-beta-glucopyranosyl-(1-->2)-alpha-rhamnopyranoside (IV), kaempferol 7- O-(6-trans)-caffeoyl)-beta-glucopyranosyl-(1-->2)-alpha-rhamnopyranoside (V), and kaempferol 7- O-beta-glucopyranosyl-(1-->2)-alpha-rhamnopyranoside (VI) were isolated and identified on the basis of their physicochemical and spectroscopic evidence (UV, IR, FAB(-)MS, (1)H-NMR, (13)C-NMR, (1)H- (1)H COSY, HMQC and HMBC). New compounds I-VI were named chiisanin (I), chiiribanin (II), chiiribaconin (III), chiirin (IV), chiiricanin (V), and chiirirhamnin (VI), respectively.
