ABOUT APPLICATION POSSIBILITY OF POLLEN AND SPORE ANALYSIS FOR DETECTION OF AN AFFILIATION OF "SPACE" PLANT MATRIX FOR A SINGLE SOURCE OF ORIGIN
While criminal investigations concerning distribution and use of narcotic it is necessary to carry out research on plant matrices that are impregnated with a solution of a narcotic substance. At the same time, the issue of attribution to one batch of psychoactive substances impregnated to inactive matrixes of plant origin is of particular relevance at present. The research purpose is to study possibility of using a method of spore and pollen analysis to prove belonging of a series of samples of crushed plant material of various herbs: Bidens (Herba Bidentis), Hypericum (Herba Hyperici), foliage of Salvia (Salviae folia), foliage of Tussilago (Tussilaginis farfarae folia), Chamomile flowers (Matricariae flores) and the vegetative collection of "Stomaran" to a single source of origin. To achieve desired goal it was necessary to solve the following tasks: to determine whether there was a small sample of pollen and plant spores in a quantity sufficient to calculate the reliable percentage content of separate taxa; perform spore and pollen analysis of vegetative raw materials of several series of samples: a) belonging to one lot; b) from lots of different manufacturers; c) belonging to different lots of the same manufacturer; to reveal indicators testifying the belonging of comparable series of samples to single or different sources of origin. The results of the research indicate that the revealed features of the composition of the palinoflora and the percentage content of separate components of the spore and pollen spectra, obtained as a result of the spore and pollen analysis of plant material, allows to distinguish a number of important indicators on the basis of which a confident conclusion can be made about belonging to a single or various sources of origin. Consequently, it is possible to conclude that data of the spore and pollen analysis contains extremely important evidence and have undeniable practical significance for solving the actual expert and criminalistic tasks, and the use of this method is the beginning of a new trend in the forensic palynology in the Republic of Belarus.
