Abstract

本发明公布了一种“板蓝根鲜提冷冻干燥粉末饮片”，其主要特征在于：在板蓝根采收后，趁鲜洗涤、切片、榨汁、提取，提取液浓缩成清膏后冷冻干燥，再经粉碎、过筛后真空包装。粉末饮片的含水量少于10%。本饮片质量稳定，既可以入汤剂煎煮，也可以直接入丸剂、散剂、片剂、胶囊剂，利于携带，临床使用方便。

Description

板蓝根鲜提冷冻干燥粉末饮片
技术领域
本发明属于中药饮片技术领域，尤其属于板蓝根饮片的加工领域。
背景技术
中药板蓝根为十字花科植物菘蓝Isatis indigotica Fort. 的干燥根，具有清热解毒，凉血利咽的功效。本品主要用于温疫时毒，发热咽痛，温毒发斑，痄腮，烂喉丹痧，大头瘟疫，丹毒，痈肿等的治疗，是中医临床上常见的一味中药。传统板蓝根的加工方法为：秋季采挖，除去泥沙，晒干，打包，储运。到饮片厂后，再洗涤、润软、切片、干燥、包装。此类饮片体积大，卫生学标准差，易于受潮、长霉、生虫，不利于保管，储存和运输成本高。此外，这样的饮片质量稳定性差，临床疗效难以保障，病人服用不方便，起效慢。因此，开发一种质量稳定可靠、储存/运输成本低、利于保管、携带和使用方便、起效快的新型板蓝根饮片，势在必行。目前市场板蓝根饮片，除了传统饮片之外，还有超微粉饮片和浓缩颗粒饮片两种形式，但两者都是以传统饮片为原料，其质量决定于传统饮片的质量，且超微饮片不能解决药材污染的问题；浓缩颗粒只能提取出水溶性成分。
发明内容
本发明公布了一种“板蓝根鲜提冷冻干燥粉末饮片”，其主要特征在于：在板蓝根采收后，及时净选，去除泥沙等杂质和非药用部位，于24小时内趁鲜用自来水洗净并切成2~5mm厚的片。将此切好的片加入1~5倍重量50~70℃的水中，浸泡并时时搅拌5~30分钟，过滤，药渣压榨取汁。所得药渣中再加入5~10倍重量的水，煮沸10~30分钟，趁热过滤，药渣再次榨汁，收集药汁。合并上述药汁，过60~100目筛，减压浓缩，温度为50~75℃，浓缩至相对密度为1.15~1.25的清膏。将所得清膏在-20~-80℃冰箱中冻结12~24小时后，在-20~-40℃真空冷冻干燥。冻干物再在60~80℃真空干燥至含水量低于10%，粉碎，过60目筛，真空包装，即得成品。成品饮片含(R，S)-告依春不得少于0.040％。本饮片临床一般使用量为1~5g，既可入汤剂煎服、冲服，也可直接入丸剂、散剂、胶囊剂及片剂中，从而大大提高了临床使用的便捷性和顺应性，有利于临床急症的治疗。
本发明解决了传统板蓝根饮片体积庞大、储运成本高、不利于保管、易生霉生虫、卫生学条件差、质量不稳定等诸多缺点，由于是趁鲜提取，质量比超微粉碎饮片和浓缩颗粒饮片更好。
具体实施例
将板蓝根药材采收后，净选，除去泥沙等杂质和非药用部位，在6小时内趁鲜用自来水洗净，并切成3mm厚的片。将此片加入5倍重量的70℃的纯净水，搅拌30分钟，过滤，药渣压榨取汁。 再往上述药渣中再加入8倍重量的纯净水，煮沸20分钟提取，趁热过滤，药渣再次榨汁，收集药汁。合并上述药汁，减压浓缩，温度为设定为70℃，浓缩至相对密度为1.20的清膏。将所得的清膏于-80℃冻结12小时后，在-40℃真空冷冻干燥。干燥物再用60℃真空干燥至含水量为8%，粉碎，过60目筛，真空包装，即得成品。成品饮片中(R，S)-告依春的含量为0.040％。
