Description

含苦楝素的兽用搽剂及其制法
本发明涉及一种兽用搽剂及其制备方法技术,即利用苦楝中的活性成份配制成可有效防治哺乳动物体外寄生虫--疥螨的植物质外用搽剂。
长期以来,人们单一使用化学合成的杀螨剂来防治哺乳动物疥螨病,如双甲胖、林丹、螨净、辛硫磷和敌敌畏等,螨虫产生抗虫性,防治效果越来越差,而且这类药剂对人畜毒性大易引起人畜中毒,长期使用,还会存在农药的大量残留问题,随着畜牧业的发展在一些地区疥螨的为害有逐年增加的趋势。
本发明的目的是提出一种含苦楝素的兽用搽剂,它能及时有效杀灭哺乳动物体外寄生的螨虫。
本发明的另一个目的是提供一种制备含苦楝素的兽用搽剂的生产方法,该方法工艺简单,生产周期短,成本低廉。
本发明的目的通过以下技术措施达到:
以植物苦楝皮或种子中的苦楝素为杀虫活性成份,通过与乳化剂、助溶剂、促渗透剂、分散剂按下列重量百分比配制,获得可防治哺乳动物身上寄生虫--疥螨的植物质搽剂
苦楝素 0.1%~50%,    乳化剂   2%~40%,
助溶剂 1%~20%,      促渗透剂 1%~20%,
分散剂 1%~20%,
上述乳化剂为多山梨糖醇酯,吐温,烷基硫酸钠,月桂基硫酸钠,烷基苯磺酸盐类;助溶剂为丙酮、异戊醇、苯酚、乙酸乙酯、二甲基亚砜;促渗透剂为脂肪次磺酸盐类、月桂氮卓酮、顺丁烯二酸二促酯磺酸钠;分散剂为萘磺酸盐、烷基磺酸盐、聚氧乙烯醚磺酸盐、二异丙基磷酸盐。
一种如上述含苦楝素兽用搽剂的制备方法,其特征在于:
先将苦楝树皮或楝籽充分磨碎,用石油醚回流提取浓缩蒸干获得石油醚提取物,再用95%乙醇对提取物进行回流浓缩蒸干获得乙醇提取物,将石油醚提取物和乙醇提取物合并,即得到有杀虫活性成份的苦楝素浓缩物。
在反应釜内按比例先后依次加入苦楝素浓缩物、乳化剂、助溶剂、促渗透剂和分散剂,釜内温度控制在30~60℃,充分搅拌均匀即制成搽剂。
本发明提供了一种高效、低毒、低残留的用以防治饲养哺乳动物体外寄生虫--疥螨的植物质外用搽剂。它利用苦楝中含有的杀虫杀螨活性成份,通过提取物与乳化剂、助溶剂、促渗透剂、分散剂等按一定比例组合制得搽剂,能迅速到达螨体,发挥其最大杀螨效果,使病情迅速好转,该搽剂适用于各种哺乳动物疥螨病,同时对其他体外寄生虫也具有一定的兼治效果。
实施例:按重量百分比组成为苦楝提取物45%,乳化剂25%,助溶剂10%,促渗透剂10%,分散剂10%配制成药剂。制得的搽剂用水稀释500、1000、2000倍后搽施于猪体表(1Kg/50Kg),第1天、第2天、第7天和第8天共搽四次,1月后防效达96.67%、96.67%和93.33%。
