AIM Bio-active constituents were expected to be obtained from Dendrobium fimbriatum Hook. METHODS It was extracted with 95% alcohol, distributed by petrol, isolated via column chromatography on silica gel and purified by crystallization. RESULTS Nine compounds were isolated from the stems of Dendrobium fimbriatum Hook., On the basis of spectral analyses, six compounds of them were identified as chrysophanol(3), n-dotriacodtanoic acid(5), defuscin(6), n-triacontyl cis-p-coumarate(7), β-sitosterol(8) and chrysotobibenzyl(9). CONCLUSION Chrysophanol(3) was firstly isolated from Genus dendrobium and chrysotobibenzyl(9) was found from this species for the first time.
