Sažetak
Helianthus tuberosus L. (Jerusalimska artičoka) pripada rodu Heliathus iz familije Asteraceae. Raste kao autohtona vrsta na teritorijama Srbije i Rumunije. Ovu biljnu vrstu karakteriše jedinstven hemijski sastav, a kao najdragoceniji konstituens izdvaja se inulin. Povoljan uticaj inulina na zdravlje ljudi uključuje smanjen rizik za kardiovaskularne bolesti, prebiotski efekat, prevenciju i/ili ublažavanje osteoporoze. Cilj studije je bio poređenje hemijskog sastava krtola H. tuberosus L. sa dva različita staništa na Balkanskom poluostrvu, Srbije i Rumunije. Određen je sadržaj osam glavnih komponenti biljnih sirovina sa oba geografska područja: ukupni proteini, flavonoidi, polifenolne karboksilne kiseline, redukujući šećeri, ukupni ugljeni hidrati, antioksidanti, inulin i askorbinska kiselina i izračunata kalorijska vrednost osušenog biljnog materijala. Sadržaj svih ispitivanih jedinjenja osim ukupnih ugljenih hidrata i antioksidanata je bio nešto viši u biljnoj sirovini poreklom iz Rumunije. Postoje jako male razlike u sastavu biljnih sirovina sa pomenutih staništa, pa se može smatrati da su oba biljna materijala pogodna za dalju obradu. Kalorijska vrednost čičoke koja raste u Srbiji je nešto viša od biljne vrste koja raste u Rumuniji. Obe biljne sirovine su dobri izvori inulina i predstavljaju dragoceni biljni materijal za dalju obradu.
Abstract
Helianthus tuberosus L. (Jerusalem artichoke) belongs to the Asteraceae family, genus Heliathus, and is a native species of Serbia and Romania. The most valuable constituent is inulin, which together with other constituents forms the unique content of its plant material. Inulin has the effect of reducing the risk of cardiovascular diseases; it also has beneficial effects on different gastrointestinal conditions by serving as a prebiotic and has been shown to be important in the prevention and/or the alleviation of the progression of osteoporosis. The aim of this study was the to compare the chemical compositions of H. tuberosus L. tubers growing in two different geographic areas on the Balkan peninsula, namely in Serbia and Romania. We have determined the content of the eight main components in both herbal samples: total proteins, flavonoids, polyphenolic carboxylic acids, reducing sugars, total carbohydrates, antioxidants, inulin and ascorbic acid,. Furthermore, we calculated a caloric value off or each of the herbal samples. The levels of all the investigated compounds, with the exception of the total carbohydrates and antioxidants, were slightly higher in the plants growing in Romania than in the plants growing in Serbia. Because the differences in the contents of both plant groups are very small, we propose that both materials could be considered as a suitable raw plant material for further processing. The caloric value of the plants growing in Serbia was found to be slightly higher than the caloric value of the ones growing in Romania. Both herbal samples are good sources of inulin and represent valuable raw plant material for further processing.
