talatisamine and gamma-sitosterol

To investigate the chemical constituents of the processed products of Aconitum Vilmorinian Radix.. The constituents were isolated by repeated column chromatography over silica gel, alumina and RP-C18 as well as recrystallization. The structures were elucidated on the basis of spectral analysis and physicochemical properties.. Ten compounds were obtained from the methanol extract, and they were identified as yunaconitine (1), 8-deacetyl-yunaconitine (2), geniculatine C (3), vilmorrianine B (4), vilmorrianine C(5), vilmorrianine D (6), talatisamine (7), β-sitosterol (8), β-daucosterol (9) and β-sitosterol acetate (10).. All compounds are obtained from the processed products of Aconitum Vilmoriniani Radix for the first time.
