ABSTRACT
Objective:
To study the chemical constituents from the roots and rhizomes of Rhodiola crenulata.Methods:
The chemical constituents were isolated by repeated silica gel chromatography and medium pressure column chromatography. Their structures were identified by various spectroscopic data including ESI-MS, 1H-NMR, and 13C-NMR data.Results:
Fourteen compounds were isolated from the ethyl acetate fractions of R. crenulata including 3,5-dihydroxy-3',4',7-trimethoxyflavone (1), 3,5,7,3'-tetrahydroxyflavone (2), 5,4'-dihydroxy-7,3'-dimethoxyflavone (3), kaemnpferol (4), kaemnpferol-3-O-β-D-glucopyranoside (5), kaemnpferol-3-O-α-L- rhamnopyranoside (6), tricin (7), tricin-7-O-β-D-glucopyranoside (8), quercetin (9), quercetin-3-O-β-D-glucopyranoside (10), quercetin-3-O-α-L-rhamnopyranoside (11), herbacetin-3-O-β-D-glucopyranoside (12), herbacetin-7-O-β-D-glucopyranoside (13), and herbacetin-7-O-α-L-rhamnoside (14).Conclusion:
Compounds 1-3 are isolated from the plants in Rhodiola L. for the first time, compounds 5-6, 8, 10-13 are obtained from this plant for the first time.
