摘要
通过乙醇提取、柱层析及制备液相分离,从猫爪草中分离得到1个二苯甲酮化合物,根据HRESI MS、1H NMR、13C NMR、HMBC、CD数据鉴定其结构为(R)-3-(2-(3,4-二羟基苯甲酰基)-4,5-二羟基苯基)-2-羟基丙酸,该化合物为未见文献报道的新化合物,命名为猫爪草酸。
A new benzophenone, i.e. ( R ) -3-( 2-( 3,4-dihydroxybenzoyl ) - 4,5-dihydroxyphenyl ) -2-hydroxypropanoic acid, was isolated from the roots of Ranunculus ternatus by alcoholic extraction, silica gel, ODS column chromatography and PHPLC. Its structure was elucidated by HRESI MS, 1H NMR, 13C NMR, HMBC and CD. This compound is a new benzophenone which has not been reported before, and named as ternatic acid.
