MELBOURNE, Australia - Geedka rosella ee aadka loo cuni karo waxaa ku jira antioxidants oo cilmi-baarayaasha Australiyaanka ah ay aaminsan yihiin inay gacan ka geysan karaan kor u qaadista miisaanka. Sida laga soo xigtay daraasad cusub, antioxidants iyo acids organic ee hibiscus waxay si wax ku ool ah uga hortagi karaan samaynta unugyada baruurta. Inaad yeelato xoogaa dufan ah waxay muhiim u tahay habaynta tamarta iyo heerka sonkorta ee jidhka, laakiin marka dufanku aad u bato, jidhku wuxuu dufanka dheeraadka ah u beddelaa unugyo dufan ah oo loo yaqaanno adipocytes. Marka ay dadku soo saaraan tamar badan iyaga oo aan kharash-garayn, unugyada baruurta waxay kordhiyaan cabbirka iyo tirada, taasoo keenta miisaan korodh iyo cayil.
Daraasadda hadda jirta, kooxda RMIT waxay daaweeyeen unugyada asliga ah ee bini'aadamka oo ay la socdaan phenolic iyo hydroxycitric acid ka hor inta aan loo beddelin unugyo baruur ah. Unugyada soo gaadhay hydroxycitric acid, wax isbeddel ah oo ku jira dufanka adipocyte lama helin. Dhanka kale, unugyada lagu daaweeyay soosaarka phenolic waxay ka kooban yihiin 95% dufan ka yar unugyada kale.
Daawaynta hadda ee buurnaanta waxay diiradda saaraan isbeddellada qaab nololeedka iyo daawooyinka. Inkasta oo daawooyinka casriga ahi ay waxtar leeyihiin, waxay kordhiyaan khatarta dhiig karka iyo dhaawaca kelyaha iyo beerka. Natiijooyinku waxay muujinayaan in dhirta hibiscus laga soosaaray phenolic-ka laga yaabo inay bixiso istiraatiijiyad maaraynta miisaanka dabiiciga ah ee waxtarka leh.
Ben Adhikari, oo ah borofisar ka tirsan Xarunta RMIT ee Cilmi-baarista Nafaqada, ayaa yiri: "Hibiscus phenolic soosaarayaasha ayaa kaa caawin kara abuurista badeecad cunto caafimaad leh oo aan waxtar u lahayn oo kaliya joojinta samaynta unugyada baruurta, laakiin sidoo kale waxay ka fogaato dhibaatooyinka aan loo baahnayn ee daawooyinka qaarkood. Xarunta hal-abuurka, war-saxaafadeed.
Waxaa jira xiisaha sii kordhaya ee daraasadda faa'iidooyinka caafimaad ee xeryahooda polyphenolic ee hodanka ku ah antioxidant. Waxaa laga helaa noocyo badan oo miro iyo khudaar ah. Marka ay dadku cunaan iyaga, antioxidants waxay jidhka ka saaraan molecules oksaydhiyeyaasha waxyeellada leh kuwaas oo gacan ka geysta gabowga iyo cudurrada daba-dheeraada.
Cilmi-baaris hore oo ku saabsan polyphenols ee hibiscus waxay muujisay inay u dhaqmaan sida xannibayaasha enzyme dabiiciga ah, oo la mid ah qaar ka mid ah daawooyinka ka hortagga buurnaanta. Polyphenols waxay xannibaan enzyme dheefshiidka oo loo yaqaan lipase. Barootiinkani waxa uu dufanka u kala jejebiyaa xaddi yar si uu mindhiciradu u nuugo. Dufan kasta oo xad-dhaaf ah ayaa loo beddelaa unugyo baruur ah. Marka walxaha qaarkood ay joojiyaan lipase, dufanku laguma nuugi karo jidhka, taas oo u oggolaanaysa inay u gudubto jidhka sida qashinka.
"Sababtoo ah xeryahooda polyphenolic waxay ka soo jeedaan dhirta waana la cuni karaa, waa inay yaraadaan ama ma jiraan waxyeellooyin," ayuu yiri qoraaga hogaamiyaha Manisa Singh, arday ka qalin jabisay RMIT. Kooxdu waxay qorshaynaysaa inay u isticmaasho soosaarkii hibiscus phenolic cunto caafimaad leh. Saynis yahanada nafaqadu waxay kaloo u rogi karaan soosaarta kubbado loo isticmaali karo cabitaanada soo cusboonaysiinta.
"Xidhiyeyaasha Phenolic oxidize si fudud, sidaas darteed soo koobid kaliya maaha inay kordhiso noloshooda shelf, laakiin sidoo kale waxay noo ogolaaneysaa inaan xakameyno sida loo sii daayo oo uu u nuugo jirka," ayuu yiri Adhikari. "Haddii aynaan ku koobi wayno soosaarkii, waxay ku jabi kartaa caloosha ka hor intaanan helin faa'iidada."
