Abstract
The present invention relates to the field of forest-chemistry industry and concerns questions about the complex processing of plant material, as the process produces biologically active products with a wide spectrum of uses.Aim of this invention is to develop a method for preparing coniferous foliage hydrocarbon solvent extract, not-containing volatile biologically toxic components.This goal is achieved by before-extraction-blowing through grinded foliage water steam for 2 to 2.5 hours at a temperature of 105 centigrade with a processing intensity rate of 3 to 4 kg of steam per hour calculated to 100 kg of coniferous foliage.
"plant or part of a plant, seed, plant cell, plant product, progeny or plant derived from a plant, method for controlling weeds at a site for the development of a plant, method for producing and treating a plant, to prepare and treat a seed, and to produce a plant product. "
