摘要
直接对干蚕砂用溶剂进行回流提取(不需软化),温度控制在80℃以下,缩短了周期,收率高达1.5%。
Chlorophll Cu-Na was prepared directly from silkworm droppings by reflux extraction of solvent (no softening needed). The temperature was controlled below 80℃, so that the period of production reguired is reduced and the yield has increased by about once.
