[Chemical constituents of Aconitum tanguticum].
OBJECTIVE
To study the chemical constituents isolated from the whole plant of Aconitum tanguticum.


METHODS
Chemical constituents were isolated and purified from the title plant by using a combination of various chromatographic techniques including column chromatography over silica gel, Sephadex LH-20, ODS and preparative HPLC. Their structures were elucidated by spectroscopic techniques including 1H-NMR, 13C-NMR, 2D-NMR, and ESI-MS.


RESULTS
Seven compounds were isolated from this plant and their structures were identified as kaempferol-3-O-[alpha-L-rhamnopyranosyl-(1-->6)-beta-D-galactopyranoside]-7-O-alpha-L-rhamnopyrano-side (1), kaempferol-3-O-[alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside]-7-O-alpha-L-rhamnopyranoside (2), kaempferol 7-O-alpha-L-rhamnopyranoside (3), gentiopieroside (4), vomifoliol-9-O-beta-D-glucopyranoside (5), dihydrovomifoliol-9-O-beta-D-glucopyranoside (6) and 3,4-dihydroxyphenyl alcohol-beta-D-glucopyranoside (7).


CONCLUSIONS
All the compounds were isolated from this plant for the first time.
