摘要
目的研究八角莲Dysosmaverslpellis（Hance）M．Cheng．vartomentosa水溶液中抗病毒的有效成分。方法八角莲水溶液经提取分离，分得单体进行结构鉴定（UV、IR、1HNMR、EI－MS和13CNMR）及体外抗病毒试验。结果分到四个单体：Ⅰ.山奈酚-3-O-β-吡喃葡萄糖甙；Ⅱ.槲皮素-3－O-β-呋喃葡萄糖甙；Ⅲ．山奈酚；Ⅳ.苦鬼臼毒素。晶Ⅱ对HSV－1有效抑制浓度（CPEI50）为0．02μg／ml，晶Ⅲ、Ⅳ对CBV的CPEI50分别为1．90（B1.3）和3.12（B1.5）.6.25（B4）μg／ml；而对HSV－1的CPEI50分别为0．03μg／ml和5．00×10－4μg／ml．结论晶Ⅱ只对HSV－1有抑制作用，而晶Ⅲ.Ⅳ对CBV和HSV－1均有显著抑制作用。
Objective To study effective constituents of antivirus from the hydrophilicfraction of Dysosma versiPellis. Methods The compounds were isolated from the hydrophi-lic fraction of Dysosma versipellis, which were characterized (through UV, IR, 1HNMR,EI - MS and 13CNMR) and determined their antivirus effect on CB1～6V and HSV - 1 virus invitro. ResuIts Four monomers were isolated: I. kaempferol - 3 - O -β - D - glucopy-ranoside, II. quercetin - 3 - O - β- D - glucofuran0side. Ⅲ. kaempferol Ⅳ. picropodophllin.The CPEI50 of II on HSV- 1 was 0.02μg/ml, the CPEI50 of III and that of IV on CBV viruswere l.90(B1,3)μg/ml and 3.12(B1.5)μg/ml,6.25(B4)μg/ml, respectively; while on HSV - 1 viruswere 0.O3μg/ml. 5.0OX 1O-4μg/ml, respectively. Conclusion Monomer II only had effectagainst HSV- 1 virus, but IIIand IV showed better activitiy to inhibit cytopathic effect ofCBV and HSV - 1 virus infection.
