本文研究了从蚕粪中提取和测定叶绿素的条件,并对叶绿素铜钠盐的测定条件进行了一些试验。实验结果表明:90.0％丙酮作提取剂或95.0％乙醇作提取剂效果最好;提取和测定时0.Ig蚕粪需加50mg左右碳酸镁或碳酸钙;测定叶绿素及其铜钠盐时必须避光.
In this paper, the conditions of extraction and determination of chlorophyll from silkworm excrement were studied. Some experiments were carried out on the determination of copper and sodium copper chlorophyll. The experimental results showed that 90.0% acetone or 95.0% ethanol was the best extractant. When extracting and measuring 0. Ig silkworm manure, about 50 mg magnesium carbonate or calcium carbonate was needed. Chlorophyll and its copper and sodium salts must be avoided Light.
