我们经过多年反复探索实践，将叶绿体色素的提取和分离实验作了如下改进。1．选材我们曾反复采用过菠菜叶、花椰菜叶、马铃薯叶、天竺葵叶……，结果天竺葵叶最佳。因为一般学校都为初中生物实验种有大量天竺葵，一年四季都有方便采用的叶子，而且天竺葵叶研磨后的色素提取液避 After repeated exploration and practice for many years, we have made the following improvements in the extraction and separation experiments of chloroplast pigments. 1. Selection We have repeatedly used spinach leaves, cauliflower leaves, potato leaves, geranium leaves ... ..., the best results geranium leaves. Because the general school has a large number of geraniums for the junior high school biology experiment, the leaves are convenient to use throughout the year, and the pigment extraction solution after grinding the geranium leaves avoids
