The study of the natural substances obtained from the poplar buds and their use for protection against the action of ionizing radiation

Currently, natural plant extracts, which include biologically active substances, are increasingly used to produce medicines and cosmetics. In connection with the dangers of a radioecological crisis, special attention is paid finding ways protect against effects chronic exposure low-intensity ionizing radiation in conditions. there no ideal safe radioprotective agent available, we seeing great effort find these agents from sources. Poplar extract possible for use as shield γ-radiation. Samples protective screens were made poplar on paper showed significant effect. Phenolic compounds flavonoids widely present plants second metabolite considered research depending their benefits human health, healing preventing many disorders. The main properties antioxidant, anti-inflammatory, antitumor, rejuvenating, antibacterial viral, neuroprotective action. aim this work was – study Flavonoids an obtained buds possibility protection radiation. Materials methods. object vegetative organs (buds). process work, experimental studies carried out extraction separation compounds, identification flavonoids, chemical composition complexes preparations based them. Research results. Data provide by spectroscopy quantification bud can contribute optimization radioprotection procedures. components found dry 2',6'-dihydroxy-4'-methoxychalcone 2,67 %, 3,4-dihydro-2',6'-dihydroxy-4'-methoxychalcone 2,33 pinobaxin -1,91 chrysin 0,76 pinostrobin 0,04 pinocembrin 0,61 tectochrysin- 0,54 % galangin 0,18 material. results that power penetrating decreases increasing thickness screen. decreased 78 at layer 0.5 mm 10 3 thickness. Further screen (> mm), doesn’t affect dose rate. Conclusions. buds' ethanol investigated. basis effect
