Abstract
The proposed project is addressing the competive properties of local sweet cherry and plum cultivars. For that reason the content of phenols in selections of Domača češplja plum cultivar and the majority of local sweet cherry cultivars (Kozanka, Vipavka, Karnijevka, Petrovka, Tarčentka, Črna Cepika, etc.) from Goriška Brda will be analysed for the first time. Sweet cherries and plums are according to the literature characterised by significant antioxidant properties, mainly caused by phenols like anthocyanins, hydroxycinnamic acids, flavanols and flavan-3-ols. The local sweet cherry plums and sweet cherries phenols will be quantified and identified employing high performance liquid chromatography coupled with diode array detection and tandem mass spectrometry. The obtained results will be further compared to the world known commercial sweet cherry and plum cultivars phenol profile to chemically define the the geographical origin of Slovenian fruit cultivars. The value of local plums and sweet cherries will be pointed out from the fruit phenol quantification results. All the necessary chromatographic and sample preparation protocols will be developed. The nutrition value of local cherries and plums will be stressed based on phenolic amounts determined. This data could support the marketing of these local agricultural products in the future. With the results obtained from this study we could draw near to the global trend of “geographical origin products” marketing. The cultivars with high phenol content are more resistant to pathogens and therefore could be introduced to ecological farming. All together could stimulate restoring of local cultivars to orchards important for cultural region preservation. The Slovenian autochthon products offer diversity would increase along with recogniton and competitive position of Slovenia among big European nations and Globaly as well.
Significance for science
Our results revealed some new and so far not very known data about the phenol potential of local sweet cherry and plums cultivars. With newly developed analytical procedures in the area of HPLC-MSn we contributed to the analytical chemistry development in the field od plant phenol analysis. With the development of local Slovenian fruits polyphenol contents databasis based on chromatographically determined phenolic profile new options for determinations of Slovenian food origin and quality will be opened.
Significance for the country
The results will point out the nutrition value of chosen sweet cherry and plum cultivars from Slovenia and with that support the future marketing of these tpyical agricultural products. The cultivars with high phenol content are more resistant to pathogens and therefore could be introduced to ecological farming. All these data could stimulate restoring of local cultivars to orchards which is important for cultural region preservation. The Slovenian autochtonic products offer diversity would increase along with recogniton and competitive position of Slovenia among big European nations and Globaly as well.
