摘要
Four chemical compounds,such as diosmin(Ⅰ),5,8,4′-trihydroxy-6,7-dimethoxyflavone(Ⅱ),5,7,3′-trihydroxy-4′-methoxyflavone(Ⅲ),octacosanoic acid(Ⅳ),are isolated from draff of above-ground part of Mentha haplocalyx Briq.after extracting volatile oil by silica gel and sephadex LH-20 column chromatography methods,and the structures of these compounds are elucidated by 1H-NMR,13C-NMR and ESI-MS.The compounds of Ⅰ,Ⅱand Ⅲ are firstly isolated from draff of M.haplocalyx.
