摘 要:对菊叶三七(GnuradivaricatiumO.Hoffm.)、仙鹤草(AgrimoniapilosaLedeb.)、夏枯草(PrunellavulgarisL.)、女贞子(LigustrumlucidumAit.)和枸骨(IlexcornutaLindl.etPaxt.)的降糖作用进行了初步的研究。菊叶三七鲜样的水提物(0.2和0.4g kg)及95%乙醇提取物(0.2和0.4g kg)对正常小鼠的血糖有显著的降低作用,干样95%乙醇提取物(0.5、1.0和2.0g kg)对四氧嘧啶糖尿病小鼠的血糖有显著的降低作用,其中鲜样95%乙醇提取物(0 4g kg)的降糖作用优于优降糖,干样95%乙醇提取物(2.0g kg)的降糖作用与降糖灵(0.1g kg)相当。仙鹤草的水煎液(30和60g kg)对正常小鼠的血糖有显著的降低作用,95%乙醇提取物(30、60和120g kg)对四氧嘧啶糖尿病小鼠的血糖均有一定的降低作用。夏枯草的95%乙醇提取物(30、60和120g kg)和女贞子的95%乙醇提取物(11.25和22.50g kg)对四氧嘧啶糖尿病小鼠的血糖均有一定的降低作用。枸骨的正丁醇提取物(30和60g kg)对四氧嘧啶糖尿病小鼠和正常小鼠的血糖均没有影响。实验结果表明,菊叶三七是一种值得开发的降糖植物资源。<Abstrcat> Pharmacological experiments of \%Gnura divaricatium \%O. Hoffm., \%Agrimonia pilosa \%Ledeb., \%Prunella vulgaris \%L., \%Ligustrum lucidum \%Ait. and \%Ilex cornuta \%Lindl. et Paxt. on lowering blood glucose were carried out. The water and 95% ethanol extracts (0.2 and 0.4 g/kg) from fresh herbs of \%G. divaricatium \%showed remarkable effects on lowering blood glucose level to normal mice, in which the dose 0.4 g/kg of the 95% ethanol extracts showed more efficiency than glyburide. The 95% ethanol extracts (0.5, 1.0 and 2.0 g/kg) from dried herbs of \%G. divaricatium \%could obviously decrease blood glucose to alloxan diabetic mice, in which the dose 2.0 g/kg of it showed equivalent effect as same as 0.1 g/kg phenformin. The doses 30 and 60 g/kg of the boiled water extracts from \%A. pilosa \%possessed a remarkable effect on lowering blood glucose level to normal mice, while its 95% ethanol extracts (30, 60 and 120 g/kg) played certain role in lowering blood glucose level to alloxan diabetic mice. The 95% ethanol extracts from \%P. vulgaris \%(30, 60 and 120 g/kg) and \%L. lucidum \%(11.25 and 22.50 g/kg) all exerted some effects on lowering blood glucose level to alloxan diabetic mice. However, the \%n\%\|butanol extracts from \%I. cornuta \%(30 and 60 g/kg) had no effect on decreasing blood glucose level to both alloxan diabetic mice and normal mice. The results showed \%G. divaricatium \%was an outstanding plant worthy to be utilized to develop medicines for diabetes mellitus.
