Rezumat: In the present study it was established the concentration of ginkgolides A, B, C and bilobalide in the leaves of 6 Ginkgo biloba trees, located in 6 different settlements in Bulgaria - Plovdiv, Pazardjik, Asenovgrad, Hisar, Karlovo and Kazanluk. Only female trees aged 20-30 years, with very good decorative characteristics, were selected. The material studied was the leaves collected in two weeks, from the appearing of the leaves up to the fall of the leaves. It was found that the concentration of test substances was the lowest in spring and autumn, and the highest in the early summer. The differences between the six studied trees were significant. With the highest concentration of ginkgolides A, B, C and bilobalide were the trees from Plovdiv and Hissar. Of the three types of ginkcolides - A, B and C - the highest content in the leaves is ginkcolid A, followed by ginkcolid B and finally, the lowest content is ginkcolid C.
