Abstract

本发明公开了一种微波辅助干燥加工商品大黄的方法,采集3年及3年以上的鲜大黄,趁鲜处理,去皮和切块;将去栓皮、切成块的大黄,置于可控温、抽湿的烘房架车上,按照设置好的温度及分段加温控温程序,在50℃下烘24小时;集中进行干燥加工。根据大黄含水量达75%‑‑80%,并含有大量淀粉,淀粉遇60℃以上高温易糊化的特性,研究制订出工厂化自控加工方法,采用“微波辅助干燥法”,再用微波干燥20分钟,然后再置烘房内,在50℃下再烘24小时;测定水份不超过8.0%,与现有技术相比,本发明采用微波辅助干燥法处理,能够快速干燥,尤其是能够很好的保留大黄的药物有效成分,更利于保存,使用方便,具有推广应用的价值。

Description

一种微波辅助干燥加工商品大黄的方法
技术领域
本发明涉及一种中药材干燥加工方法,尤其涉及一种微波辅助干燥加工商品大黄的方法。
背景技术
中药大黄是多种蓼科大黄属的多年生植物的合称,也是中药材的名称。在中国地区的文献里,“大黄”指的往往是马蹄大黄。在中国,大黄主要作药用,但在欧洲及中东,他们的大黄往往指另外几个作食用的大黄属品种,茎红色,气清香,味苦而微涩,嚼之粘牙,有砂粒感。秋末茎叶枯萎或次春发芽前采挖。除去细根,刮去外皮,切瓣或段,绳穿成串干燥或直接干燥·中药大黄具有攻积滞、清湿热、泻火、凉血、祛瘀、解毒等功效。但现有技术中,大黄在采摘后,干燥方法不理想,容易破坏大黄的药性和保存价值,因此,存在改进空间。
发明内容
本发明的目的就在于为了解决上述问题而提供一种微波辅助干燥加工商品大黄的方法。
本发明通过以下技术方案来实现上述目的:
本发明包括以下步骤:
(1)采集3年及3年以上的鲜大黄,趁鲜处理,去皮和切块;
(2)将去栓皮、切成块的大黄,置于可控温、抽湿的烘房架车上,按照设置好的温度及分段加温控温程序,在50℃下烘24小时;集中进行干燥加工。根据大黄含水量达75%--80%,并含有大量淀粉,淀粉遇60℃以上高温易糊化的特性,研究制订出工厂化自控加工方法,采用“微波辅助干燥法”,
(3)再用微波干燥20分钟,然后再置烘房内,在50℃下再烘24小时;
(4)测定水份不超过8.0%,测定药用有效成份:大黄素、大黄酚、大黄酸、大黄素甲醚、芦荟大黄素总量应≥1.5%;
(5)最后分档包装储存,即为符合药典规定的药用大黄商品。
具体地,所述大黄为掌叶大黄、药用大黄或唐古特大黄的根茎。
本发明的有益效果在于:
本发明是一种微波辅助干燥加工商品大黄的方法,与现有技术相比,本发明采用微波辅助干燥法处理,能够快速干燥,尤其是能够很好的保留大黄的药物有效成分,更利于保存,使用方便,具有推广应用的价值。
具体实施方式
下面对本发明作进一步说明:
本发明包括以下步骤:
(1)采集3年及3年以上的鲜大黄,趁鲜处理,去皮和切块;
(2)将去栓皮、切成块的大黄,置于可控温、抽湿的烘房架车上,按照设置好的温度及分段加温控温程序,在50℃下烘24小时;集中进行干燥加工。根据大黄含水量达75%--80%,并含有大量淀粉,淀粉遇60℃以上高温易糊化的特性,研究制订出工厂化自控加工方法,采用“微波辅助干燥法”,
(3)再用微波干燥20分钟,然后再置烘房内,在50℃下再烘24小时;
(4)测定水份不超过8.0%,测定药用有效成份:大黄素、大黄酚、大黄酸、大黄素甲醚、芦荟大黄素总量应≥1.5%;
(5)最后分档包装储存,即为符合药典规定的药用大黄商品。
具体地,所述大黄为掌叶大黄、药用大黄或唐古特大黄的根茎。
以上显示和描述了本发明的基本原理和主要特征及本发明的优点。本行业的技术人员应该了解,本发明不受上述实施例的限制,上述实施例和说明书中描述的只是说明本发明的原理,在不脱离本发明精神和范围的前提下,本发明还会有各种变化和改进,这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
