  摘要:对肉苁蓉、艾叶和鱼腥草3种药材分别利用普通粉碎机与超微粉碎机常温粉碎制得普通粉碎药粉与超微粉碎药粉,在扫描电子显微镜下观察药粉粉末的显微形貌特征,并利用分光光度法或高效液相色谱法对其主要功能性成分的溶出率进行测定。结果表明,3种药材的超微粉与普通粉相比粒度明显变小,且大小均匀;肉苁蓉超微粉中的毛蕊花糖苷和松果菊苷溶出率都显著高于普通粉,而其总黄酮溶出率低于普通粉,且差异极显著;艾叶超微粉中总黄酮溶出率高于普通粉,且差异显著,但挥发油含量显著低于普通粉;与鱼腥草普通粉相比,鱼腥草超微粉中总黄酮、槲皮苷与金丝桃苷的溶出率均显著提高,而鱼腥草素溶出率没有显著性差异。与普通粉相比,3种药材超微粉的粒度变小,且较为均一;但由于药材本身特性不同,主要功能性成分溶出率并没有完全增加,因此在药物生产实践中应根据不同的药材性质与现实需要选择合理的粉碎方法。

  Abstract: The ordinary powder and ultrafine powder of herba cistanches, wormwood leaves and herba houttuyniae was obtained by ordinary grinder and ultrafine grinding mill at room temperature, respectively. The microscopic morphology of the medicinal powder was observed by scanning electron microscopy, and the extraction rate of main functional components was determined by spectrophotometric or high performance liquid chromatography. For the three herbs, the particle size of ultrafine powder was obviously smaller and more uniform than of ordinary powder. For ultrafine powder of herba cistanche, the dissolution rate of verbascoside and echinacoside was significantly higher than ordinary powder, while the total flavonoid content was very significantly lower. For ultrafine powder of wormwood leaves, the dissolution rate of total flavonoids was significantly higher than ordinary powder, while the volatile oil content was significantly lower. For herba houttuyniae ultrafine powder, the dissolution content of total flavonoids, quercetin and hyperoside was significantly higher; while of houttuyfonate was not significantly changed. Due to the characteristics of different herbs, the dissolution rate of main functional components in ultrafine powder and ordinary powder was not the same, thus the grinding method in drug manufacturing practice should be chose depending on the target ingredients and properties of the herb.

  肉苁蓉又名金笋、地精、苁蓉、大芸,为列当科(Orobanchaceae)肉苁蓉属(Cistanche Hoffmg. et Link)植物肉苁蓉(C.deserticola Y.C.Ma)或管花肉苁蓉[C. tubulosa(Schenk)Wight]的干燥带鳞叶的肉质茎,主产于内蒙古、甘肃、新疆、青海省(自治区)等地[1]。近年来,肉苁蓉以其独特的医疗、保健功效在治疗疾病、保障健康中发挥着重要的作用。传统医学认为肉苁蓉具有补肾阳、益精血、润肠通便的作用,现代药理研究证明肉苁蓉及其有效成分具有抗疲劳、抗衰老、抗肿瘤、增强机体免疫力等药理作用,因而备受人们的关注,成为医药领域研究的热点之一[2]。艾叶是菊科(Compositae)蒿属(Artemisia L.)植物艾草(A. argyi H. Lév. & Vaniot)的干燥叶,中医在长期的实践中认为艾叶性味苦、温、辛,有逐寒湿、温经、理气血、止血、安胎等功效,在临床上主要用于各类杀虫止痒、出血症、内科、妇科等疾病;艾叶作为治病的药物有二千年以上的历史,特别是近年来对艾叶的研究逐渐深入,其应用范围也日益拓展。鱼腥草是三白草科(Saururaceae)蕺菜属(Houttuynia Thunb.)植物蕺菜(H. cordata Thunb.)的全草,是卫生部确认的“药食两用”资源之一,它在食品、药品等方面都具有较大的开发潜力;作为食品,它富含多种维生素、矿物质、蛋白质等营养成分,具有良好的食用价值;作为药品,又具有抗氧化、抑制细菌、抗病毒、抗炎症、抗肿瘤和提高免疫力等生理功效[3]。
