Abstract
OBJECTIVE
To study the chemical constituents of the leaves from Rhododendron delavayi.
METHODS
The compounds were isolated and purified using column chromatography with silical gel and Sephadex LH-20, and their structures wer identified by their physical and spectral data.
RESULTS
Eight compounds were isolated and elucidated as 3',4',7-trihydroxy-3,5-dimethoxyflavone (1), 3',4',5,7-tetrahydroxy-3-methoxyflavone(2), quercetin-3-O-beta-D-arabinopyranoxide(3), catechin(4), epicatechin (5), epicatechin-(2beta-->O-->7,4beta-->8)-ent-epicatechin(6), (2S)-4-(3,4-dihydroxyphenyl) -2-butanol(7), (3,4-dihydroxyphenyl)-2-ethanol(8).
CONCLUSION
Compounds 2,3,6,7,8 are isolated from this plant for the first time.
