Latvijā sastopamo briofītu ķīmiskā sastāva daudzveidība, bioloģiskā aktivitāte un ietekmējošie faktori

description

Ņemot vērā briofītu izcilās adaptācijas spējas tie bieži tiek izmantoti kā bioindikatori, taču vides faktoru un piesārņojuma ietekme uz briofītu ķīmisko sastāvu ir salīdzinoši maz pētīta. Maģistra darba mērķis bija veikt Latvijā izplatītu briofītu sastāva un bioloģiski aktīvo savienojumu klātbūtnes, ķīmiskās un bioloģiskās daudzveidības kopsakarību izpēti. Tika noskaidrots, ka lignīns nav uzskatāms par būtisku briofītu uzbūves struktūrelementu. Briofītu sekundārie metabolīti raksturo vides stresa iedarbību un pēc stresora. Pētīto briofītu ekstraktos pierādīta 109 savienojumu klātbūtne un noteikts to daudzums, tajā skaitā atrasti savienojumi ar bioloģisku aktivitāti, kā arī nezināmi un neidentificēti savienojumi. Konstatēts, ka briofītu ekstraktvielām piemīt antimikrobiāla un pretvēža aktivitāte, un to izpēte uzskatāma par perspektīvu jaunu bioloģiski aktīvu savienojumu meklējumos, attīstot biofarmācijā izmantojamus produktus.
