采用Ｌ９（３４）正交试验法，考察了木药材的粒度、烘烤温度、烘烤时间对木袋泡剂浸出率的影响。结果表明：药材粉碎过１６目筛，烘烤温度为１６０℃，烘烤时间为１０ｍｉｎ，使浸出率达到了２６２５％以上。质量研究表明在此条件下制成的袋泡剂总皂甙应控制在７８５％。 L9 (34) orthogonal test was used to investigate the effect of particle size, baking temperature and baking time on the leaching rate of eucalyptus. The results showed that the medicinal material was crushed through a 16-mesh sieve, the baking temperature was 160°C, and the baking time was 10 minutes. The leaching rate reached 2625%. Quality studies have shown that the total soap saponin made in this condition should be controlled at 7 to 85%.
