红背山麻杆叶的化学成分研究（Ⅲ）-奎宁酸类化合物
Chemical constituents from the leaves of Alchornea trewioides (Ⅲ).Quinic acids
摘要
Abstract
Alchornea trewioides is a kind of Traditional Chinese Medicine,which was used to treat prostate gland,shi-gella,lumbocrural pain,inflammation and other diseases in China,and its chemical constituents and antioxidation ac-tivity have been reported.To continue invested the chemical composition and master the material basis of A. trewioides,80% acetone extracts of the fresh leaves of A.trewioides was successively separated by Sephadex LH-20,MCI gel CHP 20P,and Toyopearl Butyl-650C column chromatography to yield five quinic acids.Their structures were elucidated spectroscopic analyses as:3-O-caffeoylquinic acid(1),4-O-caffeoylquinic acid(2),5-O-caffeoylquinic acid(3),4-O-galloylquinic acid (4),and 5-O-galloylquinic acid(5).Compounds 1-5 were isolated from the Alchornea for the first time.Oxygen radical absorbance capacity (ORAC)of the all compounds were also compared and com-pounds 1-5 were observed to show the strongest antioxidation activity.关键词
