一个顾客要买牛膝和鸡爪黄连，那儿子愚笨，不识药名，找遍竹笥也寻不到，便砍下自己耕有个人初次做中药生意。一天有事外出，吩咐儿子看守药店。

In the same time, water-soluble bidental phosphines ligand BISBIS sulfonated 2,2''-bis(diphenylphosphinomethyl-1,1''-biphenyl was synthesized, and water-soluble rhodium complex Cl was synthesized in situ. This complex which was used as catalysts to catalyze the hydrogenation of avermectin was also tested. Although the rhodium complex containing bidentate phosphine BISBIS showed a higher catalytic activity than one containing TPPDS, the selectivity for ivermectin was lower. How to improve the selectivity will be needed to studied in futur.
