New fluorenone and phenanthrene derivatives from Dendrobium chrysanthum.
Two new fluorenone derivatives denchrysans A (1) and B (2) and one new phenanthrenediglycoside denchryside A (3) were isolated from the herbs of Dendrobium chrysanthum (Orchidaceae). Their structures were established on the basis of spectral evidence.
