Description
技术领域
本发明属于中药制药技术领域;尤其涉及一种百合地黄汤物质基准的制备工艺及其质量控制方法。
背景技术
百合地黄汤来源于东汉张仲景所著的《金匮要略》,由百合七枚(擘),生地黄汁一升组成,原书中该方主要治疗百合病,原书言“百合病未经吐、下、发汗误治,病程虽长,而病情仍如初期,具备首条症状,病机为心肺阴虚内热者,主用百合地黄汤,润养心肺、凉血清热、兼能滋肾”。现代研究表明百合地黄汤具有良好抗抑郁、抗焦虑、调节亚健康状态、改善睡眠症状等作用,原方中的两种药物均为鲜品。
百合地黄汤被收录于国家中医药管理局发布的《古代经典名方目录(第一批)》中,具有较高的开发应用价值。目前,对百合地黄汤的研究大多数集中在药理方面和临床应用方面,其中对治疗失眠、抗抑郁临床疗效及作用机制等方面的研究较多,但有关百合地黄汤的制备工艺和质量控制方面的研究尚无全程控制方法,也没有全面反映该处方中所含化学成分的含量传递性及其种类的相关研究报道。
发明内容
本发明的目的是提供了一种百合地黄汤物质基准的制备工艺及其质量控制方法。

具体实施方式
下面结合具体实施例对本发明进行详细说明。应当指出的是,以下的实施实例只是对本发明的进一步说明,但本发明的保护范围并不限于以下实施例。
实施例
本实施例涉及百合地黄汤物质基准的制备工艺
处方组成、处方量及煎煮体积的分析
本实施例经过考证大量有关百合地黄汤的文献资料,并结合国家中医药管理局发布的关于《古代经典名方信息表(7首方剂)》中剂量换算关系及古代度量衡演变过程;
本实施例百合地黄汤的处方组成为:鲜百合120g,鲜地黄汁200ml;
其处方的制备工艺为:将鲜百合洗净并加入400ml纯净水,浸泡10-15h,过滤,滤液弃去,药材中再加入400ml纯净水,煎煮至约为200ml,趁热滤过,收集滤液并加入200ml鲜地黄汁,共煎至约为300ml,即得。
煎煮工艺的分析
该方煎煮过程分为两步煎煮:
第一步是对鲜百合进行煎煮过程,该过程严格按照古代煎煮工艺,加盖先武火煮沸再文火煎煮至规定体积。
第二步煎煮为百合煎煮液同鲜地黄汁共同煎煮过程;
本实施例所涉及的方法中,所述煎煮:设计了加盖与不加盖的方式进行煎煮,煎煮至300ml。取煎煮液1ml,加初始流动相定容至10ml,摇匀,过膜,测定其中梓醇、地黄苷D和益母草苷的含量并测定其放置一定时间内的稳定性,结果见表1、2。通过实验结果,优选最终煎煮工艺。
表1
表2
结果表明:百合地黄汤第二步煎煮加盖或不加盖对指标成分的含量影响是一致的,且各实验组中指标成分在3天内稳定性良好;但从煎煮时间长短来看,不加盖全程武火用时最短。因此,从耗时及能耗上考虑,初步确定百合地黄汤煎煮工艺为第一步煎煮过程先武火至沸,再转为文火(由400ml溶液煎煮至约为200ml,加盖);第二步煎煮过程选用全程武火(由400ml溶液煎煮至约为300ml,不加盖)。
物质基准干燥工艺的分析
选用常温烘干法、减压干燥法、真空冷冻干燥法以及喷雾干燥法对百合地黄汤进行干燥处理,以干燥物的颜色和样品中指标成分的含量为考察指标,对百合地黄汤物质基准的干燥方法进行研究,实验结果见表3。
表3
干燥方法 | 称样量g | 梓醇峰面积/ml | 地黄苷D峰面积/ml | 益母草苷峰面积/ml |
干燥前 | / | 1368.482 | 304.658 | 357.450 |
加热干燥 | 0.12445 | 299.845 | 248.004 | 131.298 |
减压干燥 | 0.12811 | 697.086 | 202.976 | 220.693 |
冷冻干燥 | 0.12584 | 1117.459 | 252.681 | 298.556 |
喷雾干燥 | 0.12609 | 846.905 | 233.030 | 289.569 |
从上表3中可以得出,百合地黄汤经不同干燥方法干燥后,各样品之间指标成分峰面积较干燥前均有下降;真空冷冻干燥法干燥后的样品中指标成分较干燥前变化最小,因此制备物质基准时,选用真空冷冻干燥法。
本实施例涉及指纹图谱方法学

百合阴性样品制备:将鲜百合洗净并加入400ml纯净水,浸泡10h,过滤,滤液弃去,药材中再加入400ml纯净水,煎煮至约为200ml,趁热滤过,滤液中加入纯净水200ml,共煎至约为300ml,即得样品煎液。取上述液体1ml,置于10ml容量瓶中,加流动相(0.1%磷酸水溶液:乙腈=99:1),定容至刻度,摇匀,经0.45μm的滤膜过滤,即得。
