Abstract:In order to understand the chemical constituents from Lentopodium lenotopodioides (Asteraceae), eight phenylpropanoids were obtained from its whole herbs by multiple chromatographic separation techniques. On the basis of spectral data, their structures were identified as dihydrodehydrodiconiferyl alcohol 4-O-β-d-glucoside (1), dihydrodehydrodiconiferyl alcohol 9'-O-β-d-glucoside (2), dehydrodiconiferyl alcohol 9'-O-β-d-glucoside (3), dehydrodiconiferyl alcohol 9'-methyl ether-4-O-β-d-glucoside (4), (-)-pinoresinol 4-O-β-d-glucoside (5), (-)-medioresinol 4-O-β-d-glucoside (6), citrusin C (7), and caffeic acid (8). Compounds 2-7 were obtained from this species for the first time. The inhibitory rates of these compounds toward α-glucosidase were less than 50% at the concentration of 500 μmol L-1.
