[Studies on the chemical constituents in herb of Mentha haplocalyx].Zhongguo Zhong Yao Za Zhi. 2005 Jul; 30(14):1086-8.ZZ
To study the chemical constituents of Mentha haplocalyx.
The chemical constituents were isolated and purified with column chromatography and the structures were elucidated by spectral analysis.
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).
