title: [Production technology and analysis of blood circulation improving tincture].
abstract: This article deals with the production of the tincture of Ginkgo biloba leaves, Crataegus fruits and Leonurus herbs while selecting an extractant, the size of particles in a raw material and possible methods of extraction. The optimal composition of ethanol 70%, the particle size of Ginkgo biloba leaves and Crataegus fruits 2-3 mm of Leonurus herbs. The method of production--percolation, the flow speed 0.5 ml/min. The tincture was analyzed at determination of the sum of flavonoids in terms of quercetin, dry residue, relative density, ethanol concentration. The quality of the tincture was evaluated by high-pressure liquid chromatography and spectrophotometry. The stability of the tincture and its expiry date were fixed.
