摘要: 以紫茎泽兰杀螨活性主成分紫茎泽兰素A(9-羰基-10,11-去氢泽兰酮,euptox A)提取率为考查指标,对影响提取率的乙醇体积分数、料液比、提取时间、提取次数等因素在单因素试验的基础上进行正交试验优选,确定紫茎泽兰乙醇最佳提取工艺为:加20倍量(体积质量比)的95%乙醇,回流提取3次,每次1 h。将以最佳提取工艺条件提取的紫茎泽兰乙醇提取液制成加或不加氮酮的杀螨透皮剂,进行家兔皮肤的急性毒性试验和刺激性试验。结果表明,家兔完整皮肤和破损皮肤在给药72 h后没有出现急性毒性反应和刺激性。另开展临床杀螨治疗效果试验,将30只痒螨兔和26只疥螨兔分别分成6组,A、B、C、D组分别以加氮酮紫茎泽兰生药含量1.0 g·mL-1、0.5 g·mL-1和不加氮酮生药含量为1.0 g·mL-1、0.5 g·mL-1的杀螨液涂擦处理,E组为阳性对照组,注射伊维菌素0.2 mg,F组为空白对照组,涂擦0.9%生理盐水。试验结果表明,不论痒螨组还是疥螨组,杀螨效果最好的都是加氮酮高剂量组(A组)。

Abstract: To screen the extraction process of Eupatorium adenophorum and evaluate its acaricidal activity in vivo, 9-oxo-10,11-dehydro ageraphorone (euptox A), which is the main acaricidal active ingredient, was chosen as the detective index, and single factor level test and orthogonal test were carried out to investigate the influence of volume percentage of ethanol, solid to liquid ratio, extraction duration and extraction times on the extraction percentage. The optimal extraction conditions for ethanol extraction were proposed as: 95% volume percentage of ethanol, solid to liquid ratio of 1:20, extraction duration of 1 h, extraction times of three. The skin acute toxicity test and skin irritation test were carried out by sapreading the acaricidal preparations of E. adenophorum on the integral and damaged back skin of healthy rabbits. The results showed that after using the drug for 72 h, rabbits did not show any reaction of acute toxicity and irritation. In acaricidal clinical test, 30 rabbits with psoroptes mites and 26 rabbits with scabies mites were respectively divided into six groups. The animals in group A and B were treated with the acaricidal preparation contained azone and raw drug (E. adenophorum) 1.0, 0.5 g·mL-1, respectively. The animals in groups C and D were treated with the acaricidal preparation contained raw drug 1.0, 0.5 g·mL-1, which did not contain azone, respectively. The animals in group E and F were injected with ivermectin 0.2 mg (positive controls) and embrocated 0.9% normal saline on skin (negative controls), respectively. The results showed that,whether for the psoroptes mite group or the scabies mite group, the prepatation with high dose of E. adenophorum and azone worked best.
