新促孕液(新型中药促孕灌注液,new type of fertility-promoting intrauterine infusion liquid,NFPL)是用于防治母畜子宫内膜炎、卵巢静止和持久黄体性不孕症的中兽药。该药由淫羊藿、红花、益母草、黄柏等按水提醇沉法制备而成,已在畜牧生产中推广应用。半仿生提取法(semi-bionic extraction method,SBE)为近年来出现的中药提取新技术,可以提取和保留中药中更多的有效成分。本实验以淫羊藿苷、小檗碱、总生物碱、干浸膏质量为指标,采用均匀设计法优选了NFPL的SBE提取条件,旨在为进一步提高NFPL中有效成分和疗效提供理论依据。[第一段]

The uniform design and statistical analysis system(SAS) have been employed to study the reaction conditions of graft polymerization of acrylonitrile(AN) onto chitosan using K 2S 2O 8 NaHSO 3 as initiators. The optimum reaction conditions as follows: ω (chitosan)=3.35%, ω (HAc)= 2%, n (AN)/ n (chitosan)=7, n (chitosan)/ n (K 2S 2O 8)=6, n (NaHSO 3)/ n (K 2S 2O 8)=0 538, reaction time 3 5 h, temperature 40 ℃, grafting efficiency being 92 24%. The results showed that the uniform design, as compared with the orthogonal factorization method, has the advantages of timesaving and easier analyse of the influence factors.
