Abstract:
The chemical constituents of the ethanol extracts of an artificial planted herb, Rhodiola Crenulata.H were studied. The chemical constituents were isolated and purified by column chromatography and structurally elucidated by spectrum analysis. Results showed that four compounds were obtained and identified as 3,5,7,8-tetrahydroxyl flavone 4′-O-α-L–rhamnopyranoside(1), rhodiosin(2), tyrosol(3), and Salidroside(4), among which compounds 1 was firstly isolated from this kind of plant. We may conclude that the main chemical constituents and the quality of the artificial planted Rhodiola Crenulata.H were similar to those of the wild.
