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%.展开更多

Methods The chemical constituents were isolated and purified by silica gel column and Sephadex LH-20 column chromatography. Spectroscopic methods such as MS and NMR spectra were used for the structural identification. Results A new caffeate ester, named eicosyl-(Z)-caffeate (1), along with fourteen known compounds was isolated from the EtOAc part. Conclusion Compound 1 is a new compound and compounds 2-13 are isolated from the plants of Anabasis L. for the first time.展开更多
