Abstract:
OBJECTIVE:To investigate the chemical constituents of the ear of Schizonepeta mulifida (L.)Briq. METHODS:Ingredients of the ear of this plant were separated by means of solvent extraction and chromatography on silica gel and polyamide and activated charcoal. RESULTS:Three components were isolated. Their structures were elucidated based on the spectral analysis. One of them is a known compound i.e. dehydrosylvestrene (V). The other two were new compound,named neoenneaanetetraoic acid (Ⅶ),and 3-imino-N-nitrogen substituted acetamide cyclic buty amide (Ⅷ). CONCLUSION:These 3 compounds were isolated from the plant for the first time.By the way, a mixture of n-alkane was also obtained which contains seventeen n-alkane compounds proved by GC-MS.
