Description

一种羟基酪醇包合物及其制备方法和用途
技术领域
本发明属于环糊精包合物的制备领域,具体涉及一种羟丙基-β-环糊精-羟基酪醇包合物,本发明还公开了此包合物的制备方法及其用途。
背景技术
羟基酪醇(Hydroxytyrosol)是一种多酚类化合物,化学名称为3,4-二羟基苯乙醇,分子式为C8H10O3,相对分子量为154.16,有较高的水溶性和脂溶性。羟基酪醇作为一种从橄榄油中提取出的生物活性物质,安全性高,且具有较强的抗氧化活性和促进线粒体生成的生物学活性,具有抗炎、抗菌和抗氧化等多种生理活性。羟基酪醇以酚羟基作为氢供体,可将单线态氧还原成活性较低的三线态氧,减少氧自由基产生;羟基酪醇可与活性较高的自由基反应生成活性较低的多酚自由基,打断自由基链式反应;此外,羟基酪醇的邻位酚羟基可与金属离子鳌合,减少金属离子对氧化反应的催化。目前,羟基酪醇的粗提物和高纯度的羟基酪醇已经广泛应用于食品、保健品和化妆品中,但羟基酪醇对光、热等不稳定,使用过程中易氧化变色,限制了其在食品、饮料保健品、药品及护肤品的应用。
关于β-环糊精和羟基酪醇的包合作用已有过文献报道[羟基酪醇-β-环糊精包合工艺,四川师范大学学报(自然科学版)2018,41(4):539-543],其研究表明,羟基酪醇可被β-环糊精包合,所形成的包合物的光热稳定性大为提高,但是包封率不高,未进入环糊精内腔的羟基酪醇仍然存在不稳定,易变色等问题,另外采用45℃烘干制备羟基酪醇的方法,也会影响未包封的羟基酪醇的稳定性。
羟丙基-β-环糊精包合技术在食品与医药领域有广泛的应用。实验表明,羟丙基-β-环糊精及其衍生物是一类优质的包合材料,主要有下列几方面的应用:增加药物的水溶性;提高药物的稳定性;促进药物吸收,提高药物的生物利用度;减轻药物对机体的刺激及副作用;作为缓释和靶向制剂的载体材料。除此以外,羟丙基-β-环糊精还能使液态药物固体化,改变药物的不良气味,防止制剂中药物与药物、药物与辅料的相互作用等。
为了增加产品稳定性,本发明采用羟丙基-β-环糊精进行包合,并加入保护剂对未进入到羟丙基-β-环糊精的羟基酪醇进行稳定,提高了包合物的稳定性,拓宽了其应用领域。
发明内容
本发明目的之一是针对呈液态的羟基酪醇,在空气中很不稳定,对光、热等不稳定,易变色且不易制剂等问题,提供一种羟基酪醇羟丙基-β-环糊精包合物的制备方法。
本发明另一目的是提供一种稳定性好、生产简单、使用方便且有效的羟基酪醇组合物的应用。
本发明的目的是通过下列技术方案实现的。
一种羟基酪醇包合物,其特征在于该包合物包括下列质量分数的原料:羟基酪醇0.5~5份,羟丙基-β-环糊精5~55份,保护剂0.5~8份。
其中,所述包合物包括以下质量分数的原料:羟基酪醇1~3份,羟丙基-β-环糊精10~40份,保护剂1~5份。
其中,所述包合物包括以下质量分数的原料:羟基酪醇2份,羟丙基-β-环糊精24份,保护剂3份。
其中,所述的羟基酪醇为含量≥98%的纯品,可以是植物提取、生物发酵或者化学合成。
其中,所述的羟基酪醇包合物的制备方法是:称取羟丙基-β-环糊精溶于水中,水浴加热至50℃,称取羟基酪醇加水溶解,将羟基酪醇水溶液缓慢滴加至羟丙基-β-环糊精水溶液中,加热搅拌包合5小时,然后加入保护剂,冷冻干燥,得到羟基酪醇包合物。
其中,所述的保护剂包括维生素C、维生素C乙基醚、维生素C葡糖苷、维生素E、维生素E醋酸酯、维生素E琥珀酸酯、维生素E亚油酸脂、对羟基苯乙酮、谷胱甘肽、谷胱甘肽乙酯、N-乙酰半胱氨酸、硫辛酸、吡咯烷酮羧酸锌盐、泛醌、泛醇、亚硫酸氢钠、亚硫酸钠其中的任意一种或两种或多种。
其中,所述的包合物的制备方法中,冷冻干燥的温度是-50℃。
其中,所述的羟基酪醇包合物可用于食品、保健食品、功能食品和化妆品的制备。
制备的含有羟基酪醇包合物的食品、保健食品、功能食品可以是适于口服的任意剂型,如胶囊、口服液、微丸、片剂、口含片;还可以包括其他任何有生理活性并用于口服的物质,还可以包括药剂学或食品上可接受的辅料。
所述的含有羟基酪醇包合物的化妆品可以是水剂、乳液、精华、乳膏、面膜等形式,还可以包括其他任何有生理活性并适用于制备化妆品的物质,还可以包括制备化妆品上可接受的辅料。
本发明的有益效果:
本发明提供的羟基酪醇组合物含有羟丙基-β-环糊精和保护剂,将该组合物配成水溶液后,光照稳定性和高温稳定性明显提高,无明显变色,这是因为发明中的羟丙基-β-环糊精能与羟基酪醇形成包合物,将一部分羟基酪醇包合在羟丙基-β-环糊精分子内腔中,而未进入分子内腔的羟基酪醇在保护剂的作用下,增强了羟基酪醇的稳定性,也增加了分子的光热稳定性。本产品溶液在-20~60℃保存条件下在所测试的时间内均显示了较好的稳定性。

3、混匀,30℃水浴0.5h,各反应管分别取出150μl×3孔,加入96孔板,测量并记录A492
4、计算酪氨酸酶抑制率
酪氨酸酶酶活抑制率(%)=100-(A1-A2)/(A0-1-A0-2)×100
5、实验结果见图2
结果表明,不同浓度的羟基酪醇包合物均具有良好的酪氨酸酶抑制作用,且具有浓度依赖性,其中,实施例3的羟基酪醇包合物活性最佳。由此可见,羟基酪醇包合物在天然美白化妆品领域及色素增加性皮肤疾病防治中具有良好的应用价值。
