[Study on chemical constituents of Cardiospermum halicacabum].

OBJECTIVE: To study the chemical constituents of Cardiospermum halicacabum. METHODS: The constituents were isolated and purified by silica gel and polyamide, their chemical structures were identified by physicochemcial properties and spectral methods. RESULTS: Eight compounds were separated and identified as: pentadecanoie acid (1), apigenin (2), protocatechuic acid (3), protocatechualdehyde (4), hentriacontanol (5), calycosin (6), rutin (7), quercetin (8). CONCLUSION: All compounds are isolated from this plant for the first time.
