Description

一种侧柏叶提取双黄酮的方法
技术领域
本发明涉及侧柏提取物的制备技术,具体是一种侧柏叶提取双黄酮的方法。
背景技术
侧柏叶为柏科植物侧柏的干燥枝梢及叶,性寒,味苦、涩,具有凉血止血、生发乌发的功效,主要用于吐血、咳血、便血、崩漏下血、血热脱发、须发早白等症。侧柏叶主要含黄酮类成分和挥发油,其疗效作用主要是通过黄酮类物质起作用的,最近大量文献报道黄酮类化合物具有抗炎、镇痛等多种作用。
黄酮类化合物的传统提取法主要有水煎煮法、浸提法或索氏提取法,但费时费力且收率低。而应用匀浆法提取植物有效成分,可以直接将物料置于匀浆机内,与提取溶剂在匀浆装置中混合匀浆,通过机械及液力剪切作用将物料撕裂和粉碎,使物料破碎和脂溶性成分的溶出同步进行。此类方法试剂用量大,纯化过程复杂,很难实现工业化生产。
发明内容
本发明的目的在于提供一种侧柏叶提取双黄酮的方法,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:
一种侧柏叶提取双黄酮的方法,包括以下步骤:
a.将新鲜的侧柏叶洗净,加入5-10倍量饱和石灰水浸泡提取2-3次,置于匀浆机内与石油醚在匀浆机中混合匀浆,提取10~15min,提取液加入超滤膜超滤,透过液再用纳滤膜浓缩,得浓缩液;
b.浓缩液冷冻干燥,加入6~8倍的60~80%的乙醇溶液,置于微波装置中,萃取10~30min,过滤,并收集滤液,减压浓缩至无醇味;
c.浓缩液通过大孔吸附树脂吸附,以6~8BV的50~70%的乙醇洗脱,收集洗脱液,浓缩,结晶;
d.结晶物再用70%乙醇溶液重结晶,干燥即得。
与现有技术相比,本发明的有益效果是:1.本发明采用植物匀浆提取法处理原料,除去叶绿素等脂溶性成分,同时由于免去了加热,从而可有效的避免双黄酮成分的破坏;2.与传统技术相比,微波提取具有提取效率高、选择性强、节省时间、节省溶剂、节能、污染小等许多优点。
