Description
技术领域
本发明属于中草药提取技术领域,具体的,涉及虫草芪参胶囊的制备及质量标准检测方法。
背景技术
虫草芪参胶囊主要由冬虫夏草、黄芪、丹参、红花以及酸枣仁制备而得,具有补肺益肾,活血化瘀等功效。适用于慢性肾炎患者导致的肺肾气虚、瘀血阻滞等证候。虫草芪参胶囊是一种有效治疗慢性肾炎的药物,其原料成分相对简单,效果好,毒副作用小,备受患者青睐。申请人在制药过程中发现,该药物制备方法比较单一,对多种原料采用相同提取工艺,存在有效成分流失的缺陷,而且虫草芪参胶囊每次需要服用4粒,每天三次,服药量过大,部分病人很难接受,容易出现排斥情绪。如何通过改进工艺,来最大限度的利用原料,提高药效,是我们需要研究的问题。
举例来说,目前市售的黄芪注射液一般采用水提醇沉的方法制备,注射剂中有效成分为黄芪皂苷,不含黄芪多糖或含量极少,而黄芪多糖也是黄芪的有效成分,具有增强免疫力、抗病毒、抗肿瘤、抗辐射、抗应激、抗氧化等作用。
发明内容
为了克服现有技术的缺陷,本发明提出虫草芪参胶囊的制备方法,该方法简单可行、最大限度提取了原料药材的有效成分,提高了药效,减少了药物服用量。
本发明还公开了虫草芪参胶囊的质量标准检测方法。
本发明是通过如下技术方案来实现的:
虫草芪参胶囊的制备方法,其包括如下步骤:步骤1)制备冬虫夏草细粉,步骤2)制备黄芪浸膏,步骤3)制备丹参红花浸膏,步骤4)制备酸枣仁浸膏,步骤5)混匀、干燥以及制粒。
具体地,所述制备方法包括如下步骤:
步骤1)制备冬虫夏草细粉:取冬虫夏草140g,粉碎成冬虫夏草细粉;
步骤2)制备黄芪浸膏:取黄芪1400g,粉碎,过200目筛,置于容器中,添加两倍重量的85%(v/v)的乙醇,200rpm搅拌提取,提取过程中控制微波功率为600W,提取时间为50min;然后置于4℃放置12h,过滤,滤渣备用;滤液减压蒸发回收乙醇,并浓缩滤液至密度为1.2g/ml的浸膏A;
将上述滤渣加两倍重量的水,搅拌均匀,然后加入0.5wt%的中性蛋白酶,在37℃酶解120min,然后煮沸5min,然后加入占滤渣两倍重量的无水乙醇,300rpm搅拌5min,然后静置12h,去除上清液,收集沉淀,加水溶解,-20℃放置12h,然后3000rpm离心,过滤去除沉淀,将滤液减压浓缩至密度为1.2g/ml的浸膏B;合并浸膏A和浸膏B得到黄芪浸膏;
步骤3)制备丹参红花浸膏:取丹参560g,粉碎,过200目筛,然后铺成3mm厚度的平层,置于紫外线下照射15min,收集粉末;取红花560g,将红花和上述粉末混合,置于容器中,添加两倍重量的75%(v/v)乙醇,300rpm搅拌提取,提取过程中控制微波功率为600W,提取时间为30min;过滤,收集滤液,减压回收乙醇,浓缩成1.3g/ml的丹参红花浸膏;
步骤4)制备酸枣仁浸膏:取酸枣仁280g,加水煎煮两次,第一次加8倍重量的水,煎煮2小时,过滤后得到滤液和药渣;往药渣添加5倍重量的水,煎煮1.5小时,过滤得滤液;合并上述两次的滤液,浓缩成密度为1.1g/ml的清膏,冷却,添加乙醇使含醇量达70%(体积分数),静置24小时,滤过,取上清液,减压回收乙醇,浓缩至密度为1.3g/ml的浸膏,即得酸枣仁浸膏;
步骤5)混匀、干燥以及制粒:将步骤2)所得黄芪浸膏,步骤3)所得丹参红花浸膏,步骤4)所得酸枣仁浸膏,混匀,60℃烘干,然后粉碎,加入步骤1)所得冬虫夏草细粉,混匀,干燥,制粒。
根据上述的制备方法制备的制剂。
上述制剂的质量标准检测方法,其应检出冬虫夏草、原儿茶醛以及大黄,每粒胶囊制剂含黄芪甲苷应不少于0.27mg。
本发明相对于现有技术具有如下的优点及效果:
本发明制备方法简单可行,对不同的中药成分采用不同技术进行处理,提高了各原料的有效成分,增加了药效,减少了原料浪费;丹参提取时,采用煎煮的方式,容易导致酚酸以及酮类物质的分解,本发明方法采用微波醇提的方式,避免了上述缺陷;较小的粒径能够提高黄芪有效组分的浸出率,配合微波醇提等获得苷类化合物以及多糖类,避免了成分的流失;本发明丹参提取方法采用合适强度的紫外线进行辅助破壁,提高了有效成分的溶出度,同时采用微波辅助水提,时间短,提高了提取效率,降低了能耗;红花中的绿原酸等酸类物质、酚类有效物质不易采用煎煮的方式,本发明采用微波辅助醇提,保留了有效成分,避免了绿原酸等有效的丢失;本发明制备的胶囊制剂有效成分高,效果好,动物实验提示其效果优于现有的胶囊制剂,可用于进一步的临床研究。本发明还提出了虫草芪参胶囊质量标准,有助于GMP生产车间的质量控制。
