Studies of Phenolic acid Constituents from the Whole Plant of Sarcandra Glabra

Objective To study the phenolic acid constituents from the whole plant of Sarcandra glabra.Methods Silica gel column chromatography,Sephadex LH-20,reverse phase ODS column chromatography and preparative HPLC were used to isolate the compounds whose structures were elucidated based on their physical characteristics and spectroscopic data.Results Fifteen penolic compounds were isolated from 70 % ethyl alcohol extrat of Sarcandra glabra,and they were identified as protocatechuic acid(1),caffeic acid(2),5-O-caffeoylshikimic acid(3),4-O-caffeoylshikimic acid(4),3-O-caffeoylshikimic acid(5),rosmarinic acid(6),rosmarinic acid methyl ester(7),rosmarinic acid 4-O-B-D-glucopyrannoside(8),3-O-caffeoylquinic acid(9),5-O-caffeoylquinic acid(10),4-O-caffeoylquinic acid(11),3-methoxy-4-hydroxybenzoic acid(12),caryophyllic acid(13),caffeic acid ethyl ester(14),vinyl caffeate(15),respectively.Conclusion Compounds 4,5,10,14 and 15 have been isolated from this genus for the first time,and the NMR data of compound 5 is firstly reported.
