[Chemical constituents of aerial part of Acalypha australis].

OBJECTIVE

To study the chemical constituents in the aerial part of Acalypha australis.

METHOD

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.

RESULT

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).

CONCLUSION

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