液泛提取法的分离效果王杰，宋锡瑾，任仲皎，袁誉洪，伍明（中南民族学院化学系）关键词液泛提取器；固－液萃取；传质１引言从天然产物中获得有效成分的传统提取方法主要有浸渍、渗漉、煎煮、回流提取和连续回流（索氏）提取等几种方法。这些方法或溶剂用量大、浸出率低...

Using the flooding extractor designed by authors, a process of solid-liquid extraction was studied.The curve between extraction amount and time was measured. The separation effect of flooding is compared with Soxhlex method. The mass transfer characteristics in the extractors were discussed primarily.
