Abstract

OBJECTIVE: To study the chemical constituents from Corallodiscus kingianus. METHOD: The column chromatographic techniques were applied to isolate constituents. A combination of ESI-MS and NMR spectroscopy was used to identify structures. RESULT: Six compounds were isolated from the acetone extract of this plant, and the structures of them have been identified as castanopsol (1) , 3beta-hydroxy-9 (11), 12-oleanadien-28-oic acid (2), 2,3,7-trihydroxy-6-oxo-1,3,5 (10), 7-tetraene-24-nor-frie-delane-29-oic acid methylester (3), 3-epicyclomusalenol (4), palmitinic acid (5) and stearic acid (6). CONCLUSION: Compounds 1-6 were isolated for the first time from Gesneriaceae.
