[Objective] The ZTC1+1-Ⅱ natural clarifying agent was used to flocculate alcohol-extract solution of Ginkgo biloba Linn.leaves for optimizing the production process and improving the clarity and quality of solution.[Method] There are two kinds of clarifying agent,named A and B,which are formulated by distilled water or 1% acetum and pre-swelled for 24 h then filtrated with double layer gauze.The weight of flocculation was used as the main parameters to estimate the effects of different factors on flocculation.[Result] The best flocculation technique conditions were as follows:the adding sequence of clarifying agent was clarifier B before clarifier A,the pH value of alcohol-extract solution was 5.5,the optimum amount of clarifier B and A was 1.6 and 0.8 g/L,working temperature of clarifying agent was 40 ℃,clarifying time was 40 min.[Conclusion] The study can reduce the follow-up processing and the production cost.
