Abstract
OBJECTIVE: To study the chemical constituents of Mentha haplocalyx. METHOD: The chemical constituents were isolated and purified with column chromatography and the structures were elucidated by spectral analysis. RESULT: 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). CONCLUSION: Compounds I, II, III, V, VII were first isolated from M. haplocalyx.
