On the basis of the ferment system of microbe, this paper built the method of measurement of lincomycin in fermentation broth, optimized the multi-extraction system, and researched the extracting and stripping technologies.

This paper analyzed ethyl acetatetea polyphenolswater extraction systemThe relation between mixing time and tea polyphenols concentration in extraction phase, the effect of temperature on extraction process and the change pattern of the ratio of the phase equilibrium distribution to the stages of extraction equilibrium were studied with cascade countercurrent extraction methodology.
