For the first time, studies were carried out to substantiate the system of standardization of raw materials ginkgo biloba (folia ginkgo biloba L.) introduced in the Tashkent Botanical Garden named after Academician F.N.Rusanov. The studied raw materials were harvested in August and September. The qualitative and quantitative content of the main active substance, flavonoids, was studied. Scientifically based criteria for the quality of the proposed raw materials were also determined - moisture content, totalash content and ash insoluble in 10% hydrochloric acid solution, fineness, impurity content, microbiological purity
