Abstract:
Objective To study the chemical components in the leaves of Lyciu mbarbarum(Barbary Wolfberry,Gouqi).Methods Aftersuspensionofthecrudeextractfromleavesby70%alcohol,the extraction was performed with petroleum ether,ethyl acetate and n-butanol successively.Then repeated silica gel column chromatography,Sephadex LH-20 chromatography,preparative HPLC and thin layer chromatography were applied for isolation and purification of the compounds in ethyl acetate and n-buta-nol extracts.Chemical structures of the compounds were identified by physical properties and spectra a-nalysisincluding NMRand ESI-MS.Results Atotal10 componentswereidentified:4-methoxybenzoic acid (1),4-methoxycinnamic acid (2),scopoletin (3),4-hydroxybenzaldehyde (4),4′-hydroxyaceto-phenone (5 ),(Z)-2-ethylidene-3-methylsuccinic acid (6 ),quercetin (7 ),adenosine (8 ),scopolin (9),rutin(10).Conclusion 1,2,4,6,8wereisolatedforthefirsttimefromLyciumL.,and3,5, 9 were isolated from Lycium barbarum L.for the first time.
