摘要:

Norartocarpetin 属黄酮类化合物,具有消炎、抗病毒、抑制酪氨酸酶等多种生物活性。利用95% 乙醇浸提、柱层析和薄层层析的方法,从人工三倍体桑树品种嘉陵20 号叶片中分离得到1 种黄酮类化合物,经波谱鉴定,确定其为Norartocarpetin(Mr(C15H10O6)= 286)。从桑树叶片中分离获得该化合物,有助于对桑树叶片的生物活性物质和黄酮类化合物的研究。

Abstract:

Norartocarpetin, one of the flavonoids groups, has anti-inflammatory, antibacterial, antivirus and tyrosinase inhibitory activities and other important biological activities. In the present study, norartocarpetin was obtained from leaves of artificial triploid mulberry variant, Jialing 20, by 95% alcohol extraction and silica column chromatographic purification. Based on physicochemical characteristics and NMR spectral data, the structure of norartocarpetin was identified with relative molecular weight of 286 and its molecular formula was C15H10O6. These results will provide the basis for the further research on bioactive compounds and flavones from mulberry.
