小叶黄杨叶绿素的提取工艺及应用

The extraction procedure of chlorophyll from Buxus microphylla and the application

用正交法考察了温度、时间、浸提剂比[V(乙醇)∶V(丙酮)]等因素对小叶黄杨叶绿素提取效率的影响.结果表明:小叶黄杨在浸提温度为45℃、浸提时间为4.5 h,浸提剂比[V(乙醇)∶V(丙酮)]为1∶1的条件下,叶绿素的提取效率最高.探讨用提取的天然色素试制油墨以及用最佳工艺提取其他色素.

The influences of the factors such as temperature, time, extractant ratio （ethanol：acetone） etc. on the extraction efficiency of chlorophylf from Buxus microphylla were investigated by orthogonal method. The results showed that the chlorophyll extraction efficiency was the highest when immersing Buxus microphylla at 45 for 4.5 h with immersion ratio of 1：1. The preparation of inks with the extracted natural pigments and the optimal process for the extraction of other pigments were also investigated.
