Study on the Chemical Constituents in the Chloroform Extract of Fructus Canarii / 中国药房

ABSTRACT

OBJECTIVE:To study the chemical constituents in the chloroform extract of Fructus Canarii. METHODS:The chloroform extract of Fructus Canarii was isolated and purified by MCI,Toyopearl HW-40F,reverse-phase C18,Sephadex LH-20 column. The structure of compounds was analyzed and identified by physicochemical properties and spectral data(mass spectrum, hydrogen spectrum and carbon spectrum). RESULTS:Eight compounds were isolated from chloroform extract of Fructus Canarii, namely Dihydrophaseicacid-3′-O-β-D-glucopyranoside(1),3,4-Dihydroxybenzoic acid(2),3-O-galloylquinic acid(3),Gallic acid (4), Ethyl gallate(5), Scopoletin(6), Dllagic acid-4-O-α-L-rhamnopyranoside(7) and Isocorilagin(8). CONCLUSIONS:Compounds 1,2 and 7 were firstly obtained from Fructus Canarii. The study lays foundation for quality evaluation of Fructus Canarii.
