摘　　要：目的研究民族药用植物宽药青藤的化学成分及其细胞毒活性。方法运用正相、反相硅胶,Sephadex LH-20凝胶等分离材料以及高效液相色谱法对宽药青藤乙酸乙酯层提取物的化学成分进行分离,通过核磁共振、质谱等光谱数据和物理化学性质鉴定化合物结构,并对分离得到的化合物进行细胞毒活性测试。结果从宽药青藤中共分离得到14个化合物,分别为actinodaphnine(1)、norisoboldine(2)、芒籽香碱(3)、pityriacitrin(4)、3,3′,4′-三甲氧基鞣花酸(5)、(+)-丁香脂素(6)、(+)-松脂素(7)、臭矢菜素A(8)、豆甾-4,6,8(14),22-四烯-3-酮(9)、甘草素(10)、莨菪亭(11)、异嗪皮啶(12)、大黄素甲醚(13)和大黄酚(14);四唑盐(MTT)比色法结果显示,所测试的10个化合物对MGC-803、T-47D及T-24细胞增殖无明显抑制作用。结论所有化合物均为首次从该植物中分离得到,化合物11~13为首次从该属植物中得到。OBJECTIVE To isolate and identify the chemical constituents of the ethnic medicinal plant Illigera celebica and their cytotoxic activities.METHODS The ethyl acetate extracts of I.celebica were isolate and purified by silica gel,Rp-18,Sephadex LH-20 gel column chromatographies and preparative HPLC method.The chemical structures of the isolates were illustrated by comparison their physicochemical properties and spectroscopic data with those reported.The cytotoxicity was evaluated by MTT method.RESULTS Fourteen compounds were isolated and identified as actinodaphnine(1),norisoboldine(2),atheroline(3),pityriacitrin(4),3,3′,4′-tri-O-methylellagic acid(5),(+)-syringaresinol(6),(+)-pinoresinol(7),cleomiscosin A(8),stigmasta-4,6,8(14),22-tetraen-3-one(9),liquiritigenin(10),scopoletin(11),isofraxidin(12),physcion(13)and chrysophamol(14).The tested compounds showed no significant cytotoxic activity against the MGC-803,T-47D and T-24 cell lines.CONCLUSION All the isolates are obtained from this medicinal plant for the first time,and compounds 11-13 are obtained from Illigera genus for the first time.
