Abstract


Purpose:To analysis chemical components of leaves of Oplopanax horridus,stem of Oplopanax horridus and volatile oil from leaves of Oplopanax horridus.Material and method:1.In the first part of this thesis,8 compounds were isolated from leaves and stem of Oplopanax horridus by column chromatograpy on gel silica,Sephadex LH-20,HLPC.2.In the second part,the volatile oil was extracted from O.horridus by steam distillation and analysised by GC-MS.Result:1.4 componds from leaves of Oplopanax horridus(Sm.)Miq,were isolated.The 4 compounds were dentified as:3α-hydroxy-lup-20(29)-en-23,28-dioic acid(1);3α-hydroxy-lup-20(29)-en -23,28-dioic-3-O-β-D-glucose(2);daucosterol(3);β-Sitosterol(4).Compond(1) are the first time to be got from the plant.Compound(2) is a new compound.4 componds from stem Oplopanax horridus(Sm.)Miq,were isolated.The 4 compounds wer e dentified as:Syringin(5);Adenosine(6);Coniferin(7);5’-Methoxyisolariciresinol-3α-O-β-D -glucopyranoside(8);They are the first time to be got from the plant.2.45 compounds were separated from the volatile oil and 44 of them were identified by GC-MS analysis.Indicating the maior components in the volatile oil are 2-methyl-Methylbenzene -5-heptene(34.4%)and Phytol(8.13%).Conclusion:The volatile oil was extracted from Opiopanax horridus by steam distillation and analyzed by GC-MS.The components of volatile oil from leaves of Oplopanax horridus are obviously different from the components of volatile oil from stem.
