MELBOURNE, Ositaraliya - Igihingwa cya rosella kiribwa cyane kirimo antioxydants abashakashatsi bo muri Ositaraliya bemeza ko gishobora gufasha kugabanya ibiro. Nk’uko ubushakashatsi bushya bubyerekana, antioxydants na acide kama muri hibiscus birashobora gukumira neza ingirabuzimafatizo. Kugira ibinure bimwe na bimwe ni ngombwa mu kugenzura ingufu n’isukari mu mubiri, ariko iyo hari ibinure byinshi, umubiri uhindura ibinure byinshi mu ngirabuzimafatizo bita adipocytes. Iyo abantu batanga ingufu nyinshi batayikoresheje, selile ziyongera mubunini n'umubare, biganisha ku kongera ibiro n'umubyibuho ukabije.
Mu bushakashatsi burimo gukorwa, itsinda rya RMIT ryavuye ingirangingo z'umuntu zikomoka kuri fenolike na aside hydroxycitric mbere yuko zihinduka selile. Muri selile zanduye aside hydroxycitric, nta gihinduka cyibinure bya adipocyte byabonetse. Kurundi ruhande, selile zavuwe hamwe na fenolike zirimo ibinure 95% ugereranije nizindi selile.
Ubu buryo bwo kuvura umubyibuho ukabije bwibanda ku mibereho n'imiti. Nubwo imiti igezweho ikora neza, yongera ibyago byumuvuduko ukabije wamaraso no kwangiza impyiko numwijima. Ibisubizo byerekana ko ibimera bya hibiscus bivamo ibimera bishobora gutanga ingamba zisanzwe ariko zingirakamaro zo gucunga ibiro.
Ben Adhikari, umwarimu mu kigo cya RMIT gishinzwe ubushakashatsi ku mirire, yagize ati: “Ibikomoka kuri fenolike ya Hibiscus birashobora gufasha gukora ibicuruzwa byiza by’ibiribwa bidafite akamaro gusa mu kubuza ishingwa ry’ibinure, ariko kandi birinda ingaruka mbi ziterwa n’imiti imwe n'imwe. Ikigo gishya cyo guhanga udushya, mu itangazo rigenewe abanyamakuru.
Hariho ubushake bwo kwiga ibyiza byubuzima bwa antioxyde-ikungahaye kuri polifenolike. Baboneka mubwoko bwinshi bw'imbuto n'imboga. Iyo abantu babiriye, antioxydants ikuraho umubiri wa molekile yangiza ya okiside itera umusaza n'indwara zidakira.
Ubushakashatsi bwakozwe mbere ya polifenol muri hibiscus bwerekanye ko bukora nk'imisemburo isanzwe ya enzyme, bisa n'imiti imwe n'imwe irwanya umubyibuho ukabije. Polifenole ihagarika umusemburo wigifu witwa lipase. Iyi poroteyine igabanya ibinure muke kugirango amara abashe kuyakira. Ibinure byose birenze bihinduka selile. Iyo ibintu bimwe na bimwe bibuza lipase, ibinure ntibishobora kwinjizwa mumubiri, bikemerera kunyura mumubiri nkimyanda.
Umwanditsi mukuru, Manisa Singh, umunyeshuri wahawe impamyabumenyi muri RMIT agira ati: "Kubera ko ibyo bikoresho bya polifenolike biva mu bimera kandi bishobora kuribwa, hagomba kubaho ingaruka nkeya cyangwa nta ngaruka mbi." Iri tsinda rirateganya gukoresha ibimera bya hibiscus mu biryo byiza. Abahanga mu by'imirire barashobora kandi guhindura ibiyikuramo imipira ishobora gukoreshwa mubinyobwa bisusurutsa.
Adhikari yagize ati: "Ibikomoka kuri fenolike bihindura okiside mu buryo bworoshye, bityo rero ensapsulation ntabwo yongerera igihe cyo kuramba gusa, ahubwo inadufasha kugenzura uko irekurwa kandi ikinjira mu mubiri." Ati: "Niba tudashizemo ibiyikuramo, birashobora kumeneka mu gifu mbere yuko tubona inyungu."
