Secondary metabolites from Corispermum mongolicum Iljin and their chemotaxonomic significance

摘要

A phytochemical investigation of the whole plant of Corispermum mongolicum Iljin (Chenopodiaceae) led to the isolation of thirty-eight compounds, including thirteen phenylpropanoids (1-13), six megastigmane-type norsesquiterpenoids (14-19), eight sterols (20-27), two flavonoid glycosides (28, 29), one alkaloid (30), two aromatic glycosides (31, 32), one aliphatic glycoside (33), one triterpenoid (34), one diterpenoid (35), two cerebrosides (36, 37) and one monogalactosyldiacyl glycerol (38). The chemical structures of these compounds were elucidated on the basis of spectral data and by comparisons of spectroscopic data with reported values in the literature. Twenty-eight compounds (1, 2, 4-16, 19, 20, 23-27, 30, 32-35, 37) were first found in the family Chenopodiaceae. The chemotaxonomic significance of these compounds is discussed.
