[Chemical constituents of aerial part of Acalypha australis].
OBJECTIVE
To study the chemical constituents in the aerial part of Acalypha australis.


METHODS
The aerial part of Acalypha australis were extracted with EtOH at room temperature. The compounds were separated by various kinds of chromatographic methods and their structures were identified on the basis of spectroscopic techniques.


RESULTS
Eleven compounds have been isolated and identified: emodin (1), beta-sitosterol (2), loliolide (3), 2,6-dimethoxy-1,4-benzoquinone (4), nicotinic acid (5), protocatechuic acid (6), daucosterol (7), gallic acid (8), rutin (9), succinic acid (10), brevifolin (11).


CONCLUSIONS
Compounds 1, 3-5, 10 and 11 were obtained from A. australis for the first time.
