Bioaktivne spojine v špargljih (Asparagus officinalis L.)

Markanovič, Nika (author), Abramovič, Helena (mentor)

Priljubljenost špargljev v zadnjih letih narašča, predvsem zaradi njihovega ugodnega vpliva na zdravje človeka. V okviru diplomske naloge smo želeli podati pregled literature s področja bioaktivnih snovi, ki se nahajajo v navadnem šparglju (Asparagus officinalis L.). Naloga zajema seznam in opis bioaktivnih spojin ter njihovih antioksidativnih in fizioloških učinkov. Poglobi se v delovanje različnih sekundarnih metabolitov kot so fenolne spojine, predvsem flavonoidi, fenolne kisline in antociani ter saponini in ostali antioksidanti. Podrobneje obravnava najbolj zastopane spojine, kot sta rutin in protodioscin, vključuje pa tudi v manjših koncentracijah prisotne bioaktivne komponente, kot so glutation, žveplo-vsebujoče spojine, karotenoidi, klorofili, vitamini in minerali. Opisana je tudi primerjava prisotnosti teh spojin med različnimi deli rastline. Naloga predstavi, kako različni načini pridelave in predelave vplivajo na njihovo vsebnost. Opiše vpliv organske in konvencionalne pridelave ter svetlobe in temperature na stabilnost bioaktivnih spojin. Raziskali smo tudi vpliv različnih načinov skladiščenja, kot je modificirana atmosfera, zamrzovanje in hlajenje na vsebnost omenjenih fitokemikalij. Podani so tudi rezultati določanja antoksidativnega potenciala špargljev.

Abstract

The popularity of asparagus has been rising in the recent years due to its positive effect on human health. In this graduation thesis we wanted to put forward a comprehensive review of literature from the field of bioactive compounds, that are found in the asparagus plant (Asparagus officinalis L.). This thesis includes a list and descriptions of bioactive compounds and their antioxidant and physiological effects. It dives deeper into the function of different secondary metabolites like phenolic compounds, most importantly flavonoids, phenolic acids and anthocyanidins but also includes saponins and other antioxidants. It elaborates on the most abundant compounds such as rutin and protodioscin in addition to those less represented, such as glutation, sulphur-containing compounds, carotenoids, chlorophylls, vitamins and minerals. Furthermore, it compares the content of these compounds in different parts of the plant. This thesis presents how different cultivation systems and processing methods affect bioactive compound concentrations. It focuses on the effects of organic and conventional cultivation along with light and temperature on their stability. We researched how different storage methods like modified atmosphere, freezing and chilling affect phytochemical concentrations. Results of antioxidant potential assays done on asparagus are presented as well.
