OBJECTIVE
To study the chemical constituents of ethnical drug Cissus pteroclada.
METHODS
Silica gel column chromatography was employed to separate the constituents from EtOAc extraction of Cissus pteroclada and their structures were identified by physicochemical properties as well as spectrum analysis.
RESULTS
Five steroidal compounds and 2 triterpenoid constituents were obtained. Their structures were identified as: stigmasterol (1), stigmasterol acetate (2), stigmasta-5, 22-dien-3-O-beta-D-glucopyranoside (3), beta-sitosterol (4), daucousterol (5), taraxerone (6), oleanolic acid (7).
CONCLUSION
All the compounds are isolated from this plant for the first time except for compound 4 and 5. Compounds 1 - 3 are obtained from this genus for the first time.
