所得滤液进行减压蒸馏至无有机溶剂，然后用乙酸乙酯萃取3遍，蒸干乙酸乙酯得浸膏；滤渣加入乙酸乙酯萃取3遍直至溶液颜色变浅，所得溶液经减压蒸馏后得粗浸膏，合并两者得总浸膏(120 g)。

The filtrate was distilled under reduced pressure to no organic solvent, then extracted with ethyl acetate for three times, evaporated to dry ethyl acetate to obtain the extract; the filter residue was added with ethyl acetate for three times to extract until the color of the solution became lighter, the resulting solution was distilled under reduced pressure to obtain the crude extract, and the total extract (120 g) was obtained by combining the two.<br>
