Abstract
|
|
|
|
Four known triterpenoids and one sterol glycoside were isolated from Viburnum opulus var. clavescens for. sterile flowers. By the spectral data analysis, we determined to be the structures of isolated compounds as a-amyrin (1), ursolic aldehyde (2), maslinic acid (3), ursolic acid (4) and b-sitosterol-3-O-glucoside (5). Among the isolated compounds, we revised 13C-NMR chemical shifts of ursolic aldehyde (2) using DEPT and HMBC spectra analysis. a-Amyrin (1), ursolic aldehyde (2), maslinic acid (3) and b-sitosterol-3-O-glucoside (5) were isolated for the first time from this plant.
