Abstract
Dragoljub (Tropaeolum majus L.) je jednogodišnja zeljasta biljka koja je bogat izvor vitamina C, ali i brojnih drugih biološki aktivnih komponenti za koje je dokazano da imaju ljekovita svojstva. Pripada maloj porodici Tropaeolaceae koja spada u red Capparales. Posebno znaĉajna skupina biološki aktivnih spojeva koji se mogu naći u dragoljubu su glukozinolati. Oni su kemijski stabilni i biološki neaktivni spojevi, dok njihovi razgradni produkti mogu imati razliĉite pozitivne uĉinke na organizam. U ovom radu analizirano je eteriĉno ulje koje je izolirano iz sjemenki dragoljuba postupkom mikrovalne ekstrakcije. Identifikacija spojeva u eteriĉnom ulju koji nastaju hidrolizom glukozinolata provedena je GC-MS tehnikom. Rezultati ove analize pokazali su prisutnost dva spoja, benzil nitrila u maloj i benzil izotiocijanata u prevladavajućoj koliĉini. Cilj je bio ispitati gastrointestinalnu stabilnost benzil izotiocijanata u dvofazno simuliranom modelu probave. Biodostupnost nekog spoja oznaĉava koliĉinu tog spoja koja se oslobaĊa u probavnom traktu i postaje dostupna za apsorpciju. Nakon provedenog modela in vitro probave, analiza uraĊena GC-FID tehnikom pokazala je veću stabilnost benzil izotiocijanata u želuĉanoj fazi u odnosu na crijevnu fazu probave i samim time veću biodostupnost ovog spoja u želucu.
Abstract (english)
Nasturtium (Tropaeolum majus L.) is an annual herbaceous plant, which is a rich source of vitamin C as well as other numerous biologically active compounds which are proved to have healing properties. It belongs to the small family Tropaeolaceae that belongs to the order Capparales. A particularly significant group of biologically active compounds that can be found in nasturtium are glucosinolates. They are chemically stable and biologically inactive compounds, while their degradation products can have various positive effects on the body. In this thesis essential oil isolated from nasturtium seeds by microwave extraction was analysed. The identification of compounds in the essential oil formed by glucosinolate hydrolysis was conducted using GC-MS technique. The results of this analysis showed the presence of two compounds, benzyl nitrile in small and benzyl isothiocyanate in the predominant amount. The aim was to examine the gastrointestinal stability of benzyl isothiocyanate in a simulated two-phase digestion model. The bioavailability of a compound indicates the amount of that compound that is released in the digestive tract and becomes available for absorption. Following an in vitro digestion model, analysis performed using GC-FID technique showed greater stability of benzyl isothiocyanate in the gastric phase relative to the intestinal digestion phase and, consequently, greater bioaccessibility of this compound in the stomach.
