[Studies on the chemical constituents of Blumea laciniata].

OBJECTIVE
To study the chemical constituents of Blumea laciniata.


METHODS
The chemical constituents of the ethyl acetate fraction of ethanol extract from Blumea laciniata were isolated with column chromatographic techniques. The structures of the isolated compounds were elucidated by spectroscopic analysis and comparison with their published datas.


RESULTS
Five compounds were isolated and identified as: protocatechuic acid (1), chrysoeriol (2), apigenin (3), 4-hydroxy-3,5-dimethoxbenzoic acid (4), scopolet (5).


CONCLUSION
Compounds 1 - 5 are isolated from this plant for the first time, and also obtained from this genus for the first time.
