\u010clani ARACNE konzorcija Univerze v Mariboru so se udele\u017eili mednarodne konference Polyphenols Applications 2025<\/em>, ki je potekala od 2. do 3. oktobra 2025 na Malti (https:\/\/www.polyphenols-site.com<\/a>) .<\/p>\n\n\n\n

Konferenca je bila letos osredoto\u010dena na inovativno in trajnostno uporabo fenolnih spojin, kemijske reakcije fenolov, molekularni in\u017eeniring biosintetskih poti fenolnih metabolitov, njihovo klini\u010dno uporabo ter njihov vpliv na \u010dlove\u0161ko mikrobioto. V okviru konference sta bili izvedeni dve glavni predavanji, 11 predavanj, 20 kratkih predstavitev in 62 posterjev. Na dogodku so sodelovali predstavniki znanstvenih institucij in fakultet iz 29 dr\u017eav \u2013 med njimi Belgije, Brazilije, Bolgarije, \u010cila, \u010ce\u0161ke, Finske, Francije, Hrva\u0161ke, Indije, Izraela, Italije, Japonske, Kanade, Latvije, Malte, Nem\u010dije, Nizozemske, Poljske, Portugalske, Romunije, Slova\u0161ke, Slovenije, Srbije, \u0160panije, \u0160vedske, \u0160vice, Zdru\u017eenega kraljestva in Zdru\u017eenih dr\u017eav Amerike.<\/p>\n\n\n\n

Inovativne raziskave s podro\u010dja murv in svile je na konferenci predstavil Jan Senekovi\u010d <\/strong>(Katedra za botaniko in fiziologijo rastlin, Fakulteta za kmetijstvo in biosistemske vede, Univerza v Mariboru), ki je predstavil poster z naslovom Integrating mulberry extracts and sericin for nanoparticles development: phenolic diversity, antioxidant potential and application prospect<\/em>. Poster je bil predstavljen v sklopu petkovega programa konference, katere predsednik in sopredsednik sta bila  dr. Jan Frederik Stevens<\/strong> (Univerza v Oregonu, ZDA) in dr. Andreas Schieber<\/strong> (Univerza v Bonnu, Nem\u010dija).<\/p>\n\n\n\n

Poster, ki so ga pripravili Jan Senekovi\u010d, dr. Manja Kure\u010di\u010d, dr. Maja Mikuli\u010d-Petkov\u0161ek, \u0160pela Jelen, dr. Mario Le\u0161nik, Laura Berglez, dr. Vilma Sem, dr. Andreja Urbanek Krajnc, dr. Silvia Cappellozza <\/strong>in dr. Silvo Hribernik<\/strong>, je rezultat sodelovanja Fakultete za kmetijstvo in biosistemske vede UM, Fakultete za strojni\u0161tvo UM, Biotehni\u0161ke fakultete UL, Fakultete za elektrotehniko, ra\u010dunalni\u0161tvo in informatiko UM<\/strong> ter zdru\u017eenja CREA \u2013 Kmetijstvo in okolje (Consiglio per la Ricerca in Agricoltura e l’Analisi dell’Economia Agraria)<\/strong> v okviru evropskega projekta<\/strong> Obzorje ARACNE<\/strong> (Advocating the Role of Silk Art and Cultural Heritage at National and European Scale).<\/p>\n\n\n\n

V prvi fazi raziskave so avtorji dolo\u010dili fenolne profile in antioksidativno aktivnost ekstraktov listov, skorje in soplodij razli\u010dnih vrst ter genotipov murv. Na podlagi rezultatov so izbrali hibrid M. alba <\/em>\u00d7 M. rubra<\/em>, katerega ekstrakti so izkazovali visoke vsebnosti fenolnih spojin in visoko antioksidativno aktivnost. V drugem delu raziskave so bili fenolni ekstrakti listov, soplodij in skorje omenjenega hibrida mikroenkapsulirani v sericinske nanodelce s tehniko spray-drying. Uporaba sericia, beljakovine pridobljene iz svilenih kokonov in fenolnih ekstraktov murve predstavljata odli\u010den primer uporabe stranskih produktov svilogojstva v sodobnih in okolju prijaznih tehnologijah. Sintetizirane sericinske nanodelce z enkapsuliranimi ekstrakti so ponovno ekstrahirali, dolo\u010dili njihove fenolne profile in ovrednotili antioksidativno aktivnost.<\/p>\n\n\n\n

Rezultati so pokazali, da imajo najve\u010dji potencial za mikroenkapsulacijo v sericinske nanodelce fenolni ekstrakti listov hibrida M. alba <\/em>\u00d7 M. rubra<\/em>. Razli\u010dne skupine fenolnih spojin so se v nanodelce vklju\u010devale z razli\u010dno u\u010dinkovitostjo \u2013 med najuspe\u0161nej\u0161imi so bili derivati kaempferola, kvercetina, antocianini, resorcinol tetrahidroksiflavoni in kafeoilkvini\u010dne kisline. Najni\u017ejo stopnjo inkorporacije so dosegli derivati p<\/em>-kumarne in kavne kisline ter stilbenoidi. Sericinski nanodelci z enkapsuliranimi fenolnimi ekstrakti so bili ve\u010dji in bolj nepravilnih oblik kot tisti brez enkapsuliranih ekstraktov, pri \u010demer izkazujejo potencial za uporabo v kozmeti\u010dni industriji.<\/p>\n\n\n\n

Udele\u017eba na konferenci je bila odli\u010dna prilo\u017enost za vpogled v trenutne na podro\u010dju raziskav polifenolnih spojin v rastlinah In je ponudila \u0161tevilne ideje za prihodnje raziskave ter projektne aktivnosti.<\/p>\n\n\n\n
