Abstract
Cilj ovog rada bio je odrediti kemijski sastav i biološki uĉinak hlapljivih ekstrakata biljaka puzava dobriĉica (Glechoma hederacea L.) i vazdazelena krkavina (Rhamnus alaternus L.). MeĊu spojevima koji ulaze u sastav hlapljivog ekstrakta biljke puzava dobriĉica dominira germakren D, dok meĊu hlapljivim spojevima biljke vazdazelena krkavina dominiraju -pinen i linalool. Testiranje antioksidacijskog potencijala hlapljivih ekstrakata ovih biljaka provedeno je DPPH i FRAP metodom. Rezultati su pokazali da testirani ekstrakti koncentracije 1 g/L pokazuju veoma slabu ili nikakvu antioksidacijsku aktivnost testiranu DPPH i FRAP metodom. Testiranje inhibicijskog potencijala hlapljivim ekstraktima ovih biljaka koncentracije 1 g/L provedeno je na enzime AChE i BChE metodom po Ellmanu te na enzim -glukozidazu metodom po Brueggemanu i Hollingsworthu. Uzorak hlapljivog ekstrakta biljke puzava dobriĉica pokazuje dobru sposobnost inhibicije AChE, dok ekstrakt vazdazelene krkavine slabije inhibira AChE. Ekstrakt biljke puzava dobriĉica slabo inhibira enzim BChE, dok ekstrakt biljke vazdazelena krkavina ne inhibira BChE. Hlapljivi ekstrakt biljke puzava dobriĉica pokazuje dobru sposobnost inhibicije enzima α-glukozidaza, dok ekstrakt biljke vazdazelena krkavina nije pokazao inhibiciju ovog enzima.
Abstract (english)
Aim in the thesis was to determine chemical composition and biological effect of the volatile extracts from plants such as ground ivy (Glechoma hederacea L.) and mediterranean buckthorn (Rhamnus alaternus L.). Of all the chemical compounds that constitute volatile extract from ground ivy, germacrene D is the most abundant. While chemical compounds like -pinene and linalool represent two most abundant constituents in the volatile extract of mediterranean buckthorn. Antioxidant potential tests of these volatile extracts were conducted using the DPPH and FRAP assays. Results have shown that extracts with concentracion of exactly 1 g/L, tested using DPPH and FRAP assays, display either very small or no antioxidant activity. Testing of the inhibition potential of those volatile extracts with same concentration (1 g/L), was conducted by the Ellman's method for enzymes AChE and BChE, and the Brueggan-Hollingsworth method for -glucosidase. Sample of a volatile extract from ground ivy exibits very good ability to inhibit AChE, while the extract from mediterranean buckthorn shows weaker ability to inhibit said enzyme. Extract from ground ivy inhibits BChE poorly, while extract from mediterranean buckthorn has no abilty to inhibit BChE. Volatile extract from ground ivy inhibits α-glucosidase well, but the extract from mediterranean buckthorn doesn't inhibit this enzime.
