Phytochemical investigations on the stem bark and roots of the tropical shrub Clausena anisata led to the isolation and characterization three carbazole alkaloids: girinimbine, murrayamine-A and ekeberginine; two peptide derivatives: aurantiamide acetate and N-benzoyl-L-phenylalaninyl-N-benzoyl-L-phenylalaninate; and a mixture of two phytosterols: sitosterol and stigmasterol. The structures of these compounds were established by nuclear magnetic resonance (1H-NMR, 13C-NMR, COSY, HSQC, HMQC, HMBC and NOESY) spectroscopy and electrospray ionization mass spectrometry (MS).
吉尼定、默里胺-A 和埃克贝格林;两种肽衍生物:aurantiamide 乙酸盐和 N-苯甲酰-L-苯丙氨酰-N-苯甲酰-L-苯丙氨酸;以及两种植物甾醇的混合物:谷甾醇和豆甾醇。这些化合物的结构通过核磁共振(1H-NMR、13C-NMR、COSY、HSQC、HMQC、HMBC 和 NOESY)光谱和电喷雾电离质谱(MS)确定。
