Preparation of Isatisl indigotica Fort.seed oil by superfine communication - solvent extraction
Different diameter powders of Isatisl indigotica Fort, seed obtained by superfine communication technique were used as materials to extract the oil by n - hexane. The result showed that the effect of material partical size was significant on extraction rate, and superfine communication was beneficial to oil extraction. The optimal conditions were as follows;powder diameter 7.96 u,m,the specific surface area of powder 0. 84 mVmL,ratio of material to liquid 1:12, extraction temperature 85X1 , extraction time 1 h. Under the optimal conditions,the extraction rate was 27.05%.
