Abstract:
In order to investigate the chemical constituents of glycosides in
Aconitum tanguticum (Maxim.) Stapf, column chromatographic techniques such as silica gel, ODS, Sephadex LH-20, and semi-preparative high performance liquid chromatography were used to afford eight glycosides from the
n-butanol fraction of the 85% ethanol extract of
Aconitum tanguticum. Based on the physicochemical properties and spectral data, these compounds were identified as
N-4-
O-(
β-D-glucopyranosyl)-phenethylbenzamide (
1),
N-(2'-
β-D-glucopyranosyl-5'-methoxysalicyl)-4-hydroxy-3-methoxyanthranilic acid methyl ester (
2),
N-(2'-
β-D-glucopyranosyl-5'-hydroxysalicyl)-4-hydroxy-3-methoxyanthranilic acid methyl ester (
3), salidroside (
4), benzyl primeveroside (
5), phenethanol-
β-D-xylose-(1''→6')-
β-D-glucopyranoside (
6), 4-dihydroxyphenethoxy-8-
O-
β-D-6-
O-(4-
O-
β-D-glucopyranosyl)-feruloyl-glucopyranoside (
7), phenethanol-
α-L-arabinopyranosyl-(1''→6')-
β-D-glucopyranoside (
8). Among them, compounds
1 and
2 were new compounds, and compounds
5,
6,
8 were isolated from
Aconitum tanguticum for the first time.
