OBJECTIVE
To study the chemical constituents from Corallodiscus kingianus.
METHODS
The column chromatographic techniques were applied to isolate constituents. A combination of ESI-MS and NMR spectroscopy was used to identify structures.
RESULTS
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).
CONCLUSIONS
Compounds 1-6 were isolated for the first time from Gesneriaceae.
