摘要
用正交实验结果作方差分析表明 :溶剂用量对试验结果有较显著的影响 (a =0 .10 ) ,提取温度对试验结果也有较大的影响 ,而提取时间对试验结果的影响不显著。喜树叶中水溶性糖的提取最优方案是A3C2 B3,即溶剂用量为 6 0ml,提取温度 80℃ ,提取时间 6 0min ;喜树枝中水溶性糖的提取最优方案是A2 C2 B1 ,即溶剂用量为 40ml,提取温度 80℃ ,提取时间 2 0min。通过对喜树叶与枝的成对比较分析 。
Variance analyses by using the results of orthogonal design experiments show that solvent volume and extracting temperature both have obvious influence on the experimental results(α=0.10).;however,the influence of extracting time on the experimental results is not obvious.The best scheme of extracting soluble sugar from Camptotheca acuminata Decne leaves is A 3C 2B 3:solvent volume 60ml,extracting temperature 80℃ and extracting time 60min; While the best scheme of extracting soluble sugar from Camptotheca acuminate Decne branches is A 2C 2B 1; Solvent volume 40ml,extracting temperature 80℃,and extracting time 20min. The comparative analyses of Camptotheca acuminata Decne leaves and branches show that the contents of soluble sugar in the leaves and branches make not much difference.
