title: [Technology and analysis of Ginkgo tincture].
abstract: The article deals with the production of the tincture of Ginkgo leaves while selecting extractant, the size of particles in a raw material, and the method of extraction. The optimal concentration of the extract was established by experiment and was the following: ethanol of 70 percent (V/V), the particles size 2-3 mm, the production method percolation, and the flow speed of tincture 0.5 ml/min. The tinctura was analyzed at determination of the sum of flavonoids in terms of quercetin, dry residue, the concentration of ethanol, density, refraction index, heavy metals and microbe pollution. The stability of the tincture and its expiry date were fixed.
