Objective:
To study the chemical constituents of Dendobium crystallinum.
Method:
Compounds were isolated and purified by silica gel and Sephadex LH-20 column chromatography. Their structures were identified by physicochemical properties and spectral analyses.
Result:
Nine compounds were obtained and identified as: 4, 4'-dihydroxy-3, 5-dimethoxybi-benzyl (1), gigantol (2), naringenin (3) , p-hydroxybenzoic acid (4), n-tetracosyl trans-p-cou-marate (5), n-octacosy trans-p-coumarate (6), n-hexacosyl trans-ferulate (7), stigmasterol (8), daucosterol (9).
Conclusion:
All these compounds were obtained from this plant for the first time, compounds 1 and 4 were isolated firstly from the genus.
