Chemical Constituents of Ligustrum lucidum

OBJECTIVE:To study the chemical constituents of Ligustrum lucidum.METHODS:Isolation and purification were carried out by column chromatography over silica gel,RP-ODS,Sephadex LH-20 and RP-HPLC.The chemical constituents were identified by ESI-MS and NMR.RESULTS:Eight compounds were identified as oleanolic acid(1),2α-hydroxy-oleanolic acid(2),19α-hydroxy ursolic acid(3),tormentic acid(4),3β-O-(cis-p-Coumaroyl)-2α-hydroxy oleanolic acid(5),3β-O-(trans-p-Coumaroyl)-2α-hydroxy oleanolic acid(6),3-O-cis-p-Coumaroyl tormentic acid(7),3-O-trans-p-Coumaroyl tormentic acid(8).CONCLUSION:Compounds 3,5,7,8 are isolated from this genus for the first time.
