The invention discloses a preparation method of Pueraria flavonoids extract, in which 10-20 modified dietary fibers are added to 50 parts of Pueraria flavonoids extract solution, fully stirred and centrifuged, and the precipitate obtained is dried; 6-15 parts of disintegrant and 2-8 parts of diluent are added to the dried precipitate, and after mixing evenly, 1-2 parts of adhesive are added continuously. The soft material was kneaded and made into soft material. Then the soft material was made into pellets by extruder and ball rolling machine. The flavonoid extract of Pueraria lobata was obtained. The beneficial effects are as follows: the flavonoid extract of Pueraria lobata prepared by the invention has large distribution area in the intestinal and gastrointestinal tract, small irritation to the gastrointestinal tract, good reproducibility of blood drug concentration and little influence by gastric emptying. After swallowing, the water swelling of the pellets broke the skeleton structure formed by MCC and formed pores to promote dissolution of effective components. Dietary fiber has specific adsorption on Pueraria flavonoids and its hydrophilicity is good. It stays in the intestine for a long time and can greatly improve the absorption rate of Pueraria flavonoids.

葛根黄酮提取物的制备方法
本专利技术涉及植物提取物
,具体是一种葛根黄酮提取物的制备方法。
技术介绍
葛根为豆科植物野葛Puerarialobata(Willd.)Ohwi或甘葛藤P.thomsoniiBenth.的干燥根,性味甘、辛、凉,归脾、胃经,具有解肌退热、生津、透疹,升阳止泻的功效。用于外感发热头痛、高血压颈项强痛等。现代药理学研究显示,葛根黄酮具有降低血压、降血脂、改善心脑循环、延缓动脉硬化等作用,多用于治疗高血压、冠心病、心绞痛和心率失常等心脑血管疾病。葛根中含有多种成分,现代化学研究表明,其主要的有效成分为异黄酮类化合物,其中以葛根素含量最高,其水溶性和脂溶性都比较差,口服生物利用度低。
技术实现思路
本专利技术的目的在于提供一种对胃肠道刺激性小,在肠道中停留的时间长,吸收利用率高的葛根黄酮提取物的制备方法。为实现上述目的,本专利技术提供的技术方案为:葛根黄酮提取物的制备方法,包括微丸制备:在50份葛根黄酮提取液中加入10~20份改性膳食纤维,充分搅拌后离心,并将得到的沉淀干燥;在所述干燥的沉淀中加入6~15份崩解剂和2~8份稀释剂,混合均匀后,加入1~2份黏合剂不断捏合,制成软材,然后利用挤出机和滚圆机,将软材制成微丸,得到葛根黄酮提取物。上述制备得到的葛根黄酮提取物在肠胃道分布面积大,对胃肠道刺激性小,并且血药浓度重现性好,受胃排空影响小。吞食后微丸吸水膨胀打破MCC形成的骨架结构,形成孔洞促使有效成分溶出。膳食纤维的亲水性好,在肠道中停留的时间长,人体对葛根黄酮的吸收率高。崩解剂为L-HPC;稀释剂为MCC;黏合剂为乙醇和水。葛根黄 ...
