Abstract
Gymnopusin, the first naturally occurring phenanthrene derivative having a hydroxyl group at C-9, was isolated from the orchid Bulbophyllum gymnopus. It was shown to be 7,9-dihydroxy-2,3,4-trimethoxyphenanthrene (1a) mainly from the spectral data of the compound and those of its diacetyl (1b) and dimethyl ether (1c) derivatives. © 1988.
