【Abstract】 AIM Chemical constituents were expected to be obtained from the seeds of Hovenia acerba Lindl. L. METHODS It is extracted with 95% EtOH, isolated via column chromatography on silica gel and purified by recrystallization. RESULTS Eight compounds were obtained from the material. Among them,one is an aromatic acid, six are flavanones and one is an anthraquinone. They are vanillic acid acid(H-3),kaemferol(H-4),apigenin(H-5),4′,5,7- trihydroxy-3′,5′-dimethoxy flavanone(H-6),myricetin(H-7),quercetin(H-9), dihydromyricetin(H-11),emodin(H-2). CONCLUSIONS H-2,H-3,H-4,H-5,H-6 are isolated from the seeds of Hovenia acerba for the first time.更多还原
