摘要
目的:研究虫类中药蛴螬Holotrichia diomphalia Bates的化学成分。方法:采用各种色谱材料和技术(包括硅胶、RP-18反相硅胶、Sephadex LH-20、MCI gel CHP 20P、D101大孔吸附树脂柱色谱及高效液相色谱),结合谱学方法(NMR、MS、ORD)分离鉴定蛴螬的化学成分。结果:从蛴螬的乙醇提取物中分离得到10个化合物,其结构经波谱鉴定为反-1,2-环己二醇(1),甘油醇-1-单油酸酯(2),水杨苷(3),对甲氧基苯乙酸(4),苯甲酸甘油-1-酯(5),Yangjinhualine A(6),(±)2-羟基戊二酸二甲酯(7),邻羟基苯甲醇(8),对羟基苯乙酸(9)和oxiran-2-ylmethano(l 10)。结论:化合物1~10均为首次从该种虫类中药中分离得到。
Objective: To investigate the chemical constituents of medicinal insects of Holotrichia diomphalia Bates.Methods: Various chromatography materials and technology(including silica gel,RP-18 reverse phase silica gel,Sephadex LH-20,MCI gel CHP 20P,D101 macroporous adsorption resin column chromatography and high performance liquid chromatography),combined with spectroscopic methods(NMR,MS,ORD) were applied to separate and identify the compourds of H.diomphalia Bates.Results: Ten compounds were isolated from H.diomphalia.Their structures were respectively identified as trans-1,2-cyclohexanediol(1),(9Z)glycerin-1-monooleate(2),salicin(3),4-methoxyphenyllacetic acid(4),glycerin-1-benzoate(5),yangjinhualine A(6),(±)dimerthyl-2((phenylmethoxy) methoxy) pentanedioate(7),salicyl alcohol(8),(p-hydroxyphenyl) acetic acid(9),and oxiran-2ylmethanol(10) by a suit of spectroscopic techniques.Conclusion: All the compounds were isolated from H.diomphalia for the first time.
