Aktivne učinkovine gvarane
Majhenič, Lucija ...
Raziskali smo vsebnost kofeina, celokupnih fenolov in katehinov (epikatehin, katehin in epikatehin galat) v plodovih gvarane (Paullinia cupana). Ekstrakte plodov gvarane smo pripravili s ...konvencionalnim postopkom ekstrakcije. Kot ekstrakcijska topila smo uporabili destilirano vodo, metanol, 35 % aceton in 60 % etanol. Ekstrakcije smo vršili pri sobni temperaturi in pri temperaturi vrelišča topila. Vsebnosti kofeina in katehinov v ekstraktih smo določili s pomočjo tekočinske kromatografije z visoko ločljivostjo (HPLC), vsebnost celokupnih fenolov smo določili spektrofotometrično. Raziskave so pokazale, da so vsebnosti učinkovin odvisne tako od temperature kot tudi od vrste ekstrakcijskega topila.
