Abstract
The development of a technology employing materials containing specific alkaloids from biomasses of agricultural production would be extremely beneficial and relatively inexpensive for the remediation of polluted soils and may represent a possible new industrial and commercial opportunity. We have studied detoxification and degradation of persistent chloroorganic pesticides by using plant extracts, which contained alkaloids. Reactions DDT with alkaloid Anabasine and extractive sum of alkaloids, isolated from ground up part plant Anabasis аphylla proceed more easy without solvent. It is established, that at interaction alkaloids of Anabasis aphylla with pesticide DDT occurs degradation to formation of less toxic DDE. Results the carried out researches on studying interaction sum of alkaloids, isolated from ground up part plant Anabasis Ahylla, with DDT in various ratio (1:1, 2:1, 3:1) have shown, that thus there are detoxification pesticide DDT on 35% - 45%, 75% - 80% and 80% - 85% according to formation dichlorodiphenyldichloroethylene (DDE), and in presence humic acids the degree degradation achieves to 95% - 97%.

Summary
Polychlorinated organic pesticides (POP) are well-known recalcitrant environmental pollutants. Based on the data of the State Stock Holding Company “Uzagricultural-chemistry”, in the year 1971-1988, the cited pesticides were used on 1, 7, 2, 1 billion hectares of Uzbekistan cropping areas for cotton and in the treatment of cotton seeds in the amount of 11 12 kg per ton annually For this purposes 1800 - 2000 tons of fentiuram, which consists of 40% TDTM, 15% hexachlorocyclohexane and 10% 2,3,5-trichlorophenolate of copper, were employed [1]. Tion of halogenated pesticides following new regulation after the years 1989-1990 have left huge quantities of these pesticides unused with their accumulation in uncontrolled dumps directly in soils, thereby representing a serious risk to further the environmental pollution. This situation is no longer acceptable and measures have to be taken to reduce the existing environmental contamination and preserve future generations from health hazards
