Description
本发明涉及生物提取技术领域，尤其涉及一种贝母花提取物的制备方法。
贝母花多年生草本，地下部分为二鳞片组成的球茎。茎直立，高约50公分，叶宽线形，先端细窄，有时会会呈藤蔓状缠绕，3～4枚轮生。4～5月时，会从上面部分的叶子两侧垂下吊钟形淡黄色花，观赏性佳。当浙贝植株最下两朵花开放时采摘。
贝母花有止咳化痰作用，能用于感冒、支气管炎引起的咳嗽、喉咙痛，用其鳞茎有药效作用。
发明内容
基于背景技术存在的技术问题，本发明提出了一种贝母花提取物的制备方法，不仅提取速度和提取精度高，而且生产成本低。
本发明提出的一种贝母花提取物的制备方法，包括如下步骤：
S1、将贝母花低温干燥后，粉碎，过筛，接着脱脂得到滤饼；
S2、将滤饼干燥后，加入无水乙醇中进行超声提取，接着过滤得到提取液和残渣；
S3、将残渣进行超临界二氧化碳萃取得到萃取液，以乙醇水溶液为夹带剂；
S4、将萃取液和提取液混合后，上大孔吸附树脂，然后依次采用水和乙醇水溶液洗脱，浓缩，干燥，得到贝母花提取物。
进一步地，S1中，低温干燥的温度为10～20℃，低温干燥的压力为5～10Pa，低温干燥的时间为25～28h。
进一步地，S2中，超声提取的功率为500～600w，超声提取的频率为50～60kHz，超声提取的时间为3～4h。
进一步地，S3中，超临界萃取条件为：萃取温度为52～55℃，第一次分离温度为45～50℃，第二次分离温度为35～40℃，萃取压力为30～33MPa，二氧化碳流速为10～20L/h，接收产物的频率为45～50min/次，提取时间为3～4h。
进一步地，S4的上大孔吸附树脂过程中，料液比为1：10～12，溶液的pH值为3～5。
进一步地，S3中的乙醇水溶液浓度为50～60％，S4中的乙醇水溶液浓度40～50％。
超声提取可以产生强烈振动、高加速度、强烈空化作用及搅拌作用，用于溶剂辅助提取时，可以加速贝母花提取物进入溶剂，从而缩短提取时间、节约溶剂，避免高温导致贝母花提取物分解，但超声提取得到的贝母花提取物纯度不足，残渣中残留率高；而超临界二氧化碳萃取得到的贝母花提取物纯度在85％以上，可满足各种对含有贝母花提取物成分的食品、保健品和药物的开发需求，亦可作为药物中间体使用，但往往提取速度慢。
本发明采用超声提取和超临界二氧化碳萃取进行串联，不仅提高了提取速度和提取精度，而且大大降低了生产成本，从贝母花中提取的贝母花提取物为相关企业开发生产预防和治疗肿瘤、降低血糖、保肝利胆等作用的药品和保健食品提供了优质生产原料。
