Description

一种菠萝蛋白酶制剂及其在消肿组合物中的应用
技术领域
本发明涉及蛋白酶制剂技术领域,具体涉及一种菠萝蛋白酶制剂及其在消肿组合物中的应用。
背景技术
菠萝蛋白酶是一种蛋白质水解酶,从菠萝茎中提取的菠萝蛋白酶是一种纯天然植物蛋白酶,具有很强的分解纤维蛋白和血凝块的能力,同时,菠萝蛋白酶具有消炎、增进药物吸收、防治心血管疾病、抑制肿瘤细胞生长等作用,在医药行业运用广泛。
菠萝蛋白酶作为一种酶制剂,在工业生产过程中不可避免的需要进行加工、运输和储存这样一个流通环节,而在常温状态下,作为一种生物催化剂,菠萝蛋白酶在加工、生产、运输和储存等过程中极易受到环境因素变化和微生物污染的影响;而且如环境因素温度、压力、pH和离子强度等的变化会引起酶蛋白的变性失活;此外微生物的快速增长,则会快速的导致酶蛋白被生物降解而失活。因此,提高菠萝蛋白酶的稳定性,减少生产过程中的酶活损失,尽可能的保持酶在运输、储存过程中的稳定性是提高其在工业化生产和工业化应用的关键点。
发明内容
针对现有技术的不足,本发明的目的在于提供一种菠萝蛋白酶制剂及其在消肿组合物中的应用,解决菠萝蛋白酶在运输、储存过程中易失活的技术问题。
为了实现上述目的,本发明采取如下技术方案:
一种菠萝蛋白酶制剂,由以下重量百分比的组分所组成:柠檬酸亚铁2-5%、醋酸-醋酸钠缓冲溶液3-6%、乙二醇10-20%、葡萄糖10-15%,余量为菠萝蛋白酶水溶液。
优选的,由以下重量百分比的组分所组成:柠檬酸亚铁3-4%、醋酸-醋酸钠缓冲溶液4-5%、乙二醇12-16%、葡萄糖12-15%,余量为菠萝蛋白酶水溶液。
优选的,所述醋酸-醋酸钠缓冲溶液的浓度为0.05-0.1mol/L。
优选的,所述醋酸-醋酸钠缓冲溶液的浓度为0.06-0.08mol/L。
优选的,所述菠萝蛋白酶水溶液中菠萝蛋白酶的含量为4-8%。
优选的,所述菠萝蛋白酶水溶液中菠萝蛋白酶的含量为5-6%。
本发明还提供上述菠萝蛋白酶制剂在消肿组合物中的应用。
优选的,所述消肿组合物由以下重量份的组分所组成:30-50份菠萝蛋白酶制剂、10-20份木瓜蛋白酶、5-15份甘草提取物、3-8份聚乙二醇4000、4-6份聚乙二醇400、0.5-0.8份卡波姆。
优选的,所述消肿组合物为凝胶型消肿组合物,其制备步骤如下:将木瓜蛋白酶、甘草提取物加入到菠萝蛋白酶制剂中,混合均匀,再向其中加入聚乙二醇4000、聚乙二醇400和卡波姆,搅拌混合均匀,然后静置,即得到凝胶型消肿组合物。
与现有技术相比,本发明具有如下有益效果:
本发明采用柠檬酸亚铁作为菠萝蛋白酶的活性保护剂,柠檬酸亚铁中的亚铁离子具有还原性,能有效保护菠萝蛋白酶中巯基不被氧化,同时,亚铁离子与巯基形成螯合物,使其结构更加稳定,不容易被破坏,使菠萝蛋白酶趋于更稳定的状态。
本发明采用醋酸-醋酸钠作为缓冲溶液,有利于维持体系的pH稳定性,同时醋酸钠能使菠萝蛋白酶的半衰期明显延长,醋酸-醋酸钠缓冲溶液对亚铁离子有一定的保护作用,柠檬酸亚铁与醋酸-醋酸钠缓冲溶液协同作用,共同提高菠萝蛋白酶的活力稳定性。
