本发明公开了一种阴道用抗菌组合物,由0.1‑50wt%纳米银溶液和50‑99.9wt%妇洁液组成。本发明阴道用抗菌组合物将阿娜尔妇洁液与纳米银组合,出人意料地发现阿娜尔妇洁液和纳米银组合具有协同抗菌作用。纳米银和阿娜尔洗液联合使用对金黄色葡萄球菌的MIC值较纳米银和阿娜尔洗液单用的MIC值分别降低了4倍和8倍;纳米银和阿娜尔洗液联合使用对大肠杆菌的MIC值较纳米银和阿娜尔洗液的MIC值分别降低了8倍和4倍。既可降低生产成本,又可减少对生态环境的不利影响。

Description

一种阴道用抗菌组合物及其制备方法
技术领域
本发明涉及一种银离子与中药制剂的组合抗菌药物。
背景技术
阿娜尔妇洁液是维吾尔医学中的民间验方,为《中华人民共和国卫生部药品标准-维吾尔药分册》1999年版收载品种。由蛇床子、苦豆子、冰片、没食子、珊瑚、石榴皮、花椒7味药材组成,用于细菌性、霉菌性、滴虫性外阴炎、阴道炎所致妇女阴部瘙痒、红肿、白带过多,疗效确切。
银在纳米状态下体现出明显的抗菌和抗炎作用,它的杀菌机理一般认为是银化合物或银金属粒子在接触到微生物之后会产生抑制微生物的呼吸、阻碍酶的合成、破坏蛋白质、损伤细胞膜、干扰DNA的结合的作用。
阿娜尔妇洁液中含有贵重药材珊瑚,在生产中给企业带来了经济压力,珊瑚的采挖对环境保护造成了不利影响。
发明内容
本发明要解决的技术问题是克服现有的缺陷,提供了一种可以大幅度减少了阿娜尔妇洁液的用量且抗菌效果好的阴道用抗菌组合物;
本发明的另一目的是提供上述阴道用抗菌组合物的制备方法。
本发明的目的通过以下技术方案来具体实现:
一种阴道用抗菌组合物,由0.1-50wt%纳米银溶液和50-99.9wt%妇洁液组成。
优选的,所述组合物中,纳米银浓度为0.625至100μg/mL,所述组合物溶液中,纳米银浓度为1.25μg/mL,且妇洁液被稀释20倍,此时抑菌效果最优。
优选的,所述妇洁液由石榴皮、苦豆子、蛇床子、没食子、珊瑚、花椒、冰片制备而成。
优选的,所述妇洁液采用商品名为阿娜尔妇洁液的中药制剂。阿娜尔妇洁液为一种中药制剂,批准文号:国药准字Z65020094,生产单位为新疆西部加斯特药业有限公司。
优选的,所述纳米银为球状、棒状、片状、线状、无定形状颗粒或其混合物,粒径为1-100nm。
优选的,所述纳米银按照次磷酸钠液相化学还原法制得。
上述的阴道用抗菌组合物的制备方法,按比配比量取纳米银溶液,混入妇洁液中,超声振荡或搅拌至体系分散均匀,即获得目标产物。
本发明的有益效果:
本发明阴道用抗菌组合物将阿娜尔妇洁液与纳米银组合,出人意料地发现阿娜尔妇洁液和纳米银组合具有协同抗菌作用。纳米银和阿娜尔洗液联合使用对金黄色葡萄球菌的MIC值较纳米银和阿娜尔洗液单用的MIC值分别降低了4倍和8倍;纳米银和阿娜尔洗液联合使用对大肠杆菌的MIC值较纳米银和阿娜尔洗液的MIC值分别降低了8倍和4倍。本发明提高复合抗菌剂的抗菌效能的同时,可大幅减少阿娜尔妇洁液的用量,降低生产成本,减少了对生态环境的不利影响。
具体实施方式
以下对本发明的优选实施例进行说明,应当理解,此处所描述的优选实施例仅用于说明和解释本发明,并不用于限定本发明。
实施例1:
纳米银的制备:
称取一定量的次亚磷酸钠、六偏磷酸钠和PVP溶于蒸馏水中,再加入一定浓度的H2SO4配制成还原液,将制得的还原液与一定量的AgNO3通过还原反应得到银胶溶液。再通过5%的柠檬酸钠溶液或两倍体积的丙酮使溶液进行纯化最终得到纳米银溶液。
最低抑菌浓度(MIC)的测定:
取无菌试管若干,编号并排成一排或方阵,每管加入肉汤2mL。在第1管加入待测组合物样品2mL混匀,然后吸取2mL至第2管,混匀后再吸取2mL至第3管,如此连续倍比稀释。用微量加样器取0.1mL细菌溶液依次由低浓度到高浓度加到各试管中,使每管最终菌液浓度约为5×105个/mL,以空白肉汤和肉汤加入被测细菌对照。37℃孵育24h后,完全抑制测试菌肉眼可见生长的最低浓度为药品对测试菌的MIC。
MIC的测定结果
表1 纳米银单独作用时金黄色葡萄球菌和大肠杆菌的生长情况
注:“-”代表该试管无肉眼可见的浑浊现象;“+”代表此试管中有肉眼可见的浑浊现象,数目增大代表细菌浓度增大。
由表1可知,纳米银对金黄色葡萄球菌和大肠杆菌的MIC均小于或等于5μg/mL。
表2 阿娜尔洗液单独作用时金黄色葡萄球菌和大肠杆菌的生长情况
注:“-”代表该试管无肉眼的浑浊现象;“+”代表此试管中有肉眼可见的浑浊现象,数目增大代表细菌浓度增大。
由表2可知,阿娜尔妇洁液对金黄色葡萄球菌和大肠杆菌的MIC均小于或等于20%(市售原液稀释5倍)但大于10%(市售原液稀释10倍)。
表3 阿娜尔洗液与纳米银联合用药时的金黄色葡萄球菌和大肠杆菌的生长情况
注:“-”代表该试管无肉眼可见的浑浊现象;“+”代表此试管中有肉眼可见的浑浊现象。
由表3可知,纳米银与阿娜尔洗液混合液对金黄色葡萄球菌和大肠杆菌的MIC分别为(1.25μg/mL,稀释40倍)、(0.625μg/mL,稀释20倍)。与单独使用纳米银或阿娜尔洗液的测定结果比较发现,对金黄色葡萄球菌的MIC值纳米银和阿娜尔洗液的MIC值分别降低了4倍和8倍;对大肠杆菌的MIC值纳米银和阿娜尔洗液的MIC值分别降低了8倍和4倍。
协同作用的判断
FIC值(部分抑菌浓度)用于表明协同活性并且被描述于L.B.Quesnel,A.R. Al-Naijar和P.Buddhavudhikrai在Journal of Applied Bacteriology,1978,Vol.45, 397-405页,L.O.Garrod, H. P.Lambert,F.O’Grady和P.M.water worth在Antibiotic andChemotherapy,282-286及514-518页中。
根据这个公式,阿娜尔妇洁液加纳米银溶液对于金黄色葡萄球菌的FIC为0.625,对大肠杆菌的FIC为0.375,表明该组合作为抗菌混合物显示出协同作用。
以上所述仅为本发明的优选实施例而已,并不用于限制本发明,尽管参照前述实施例对本发明进行了详细的说明,对于本领域的技术人员来说,其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
