[Studies on the chemical constituents in herb of Mentha haplocalyx].
OBJECTIVE
To study the chemical constituents of Mentha haplocalyx.


METHODS
The chemical constituents were isolated and purified with column chromatography and the structures were elucidated by spectral analysis.


RESULTS
Nine compounds were obtained and identified as emodin (I), chrysophanol (II), physcione (II), benzoic acid (IV), trans-cinnamic acid (V), beta-sitosterol (VI), aloe-emodin (VII), ursolic acid (VIII) and daucosterol (IX).
