MELBOURNE, Ositaraliya — Iki gihingwa cya rosella kiribwa cyane kirimo antioxydants abashakashatsi bo muri Ositaraliya bemeza ko gishobora gufasha mu kugabanya ibiro. Nk’uko ubushakashatsi bushya bwabigaragaje, antioxydants na aside organic ziri muri hibiscus bishobora gukumira ikorwa ry’uturemangingo tw’ibinure. Kugira ibinure bimwe ni ingenzi mu kugena ingufu n’isukari mu mubiri, ariko iyo hari ibinure byinshi, umubiri uhindura ibinure byinshi mo uturemangingo tw’ibinure twitwa adipocytes. Iyo abantu bakora ingufu nyinshi batazikoresheje, uturemangingo tw’ibinure turiyongera mu bunini no mu bwinshi, bigatuma ibiro byiyongera kandi bikagira umubyibuho ukabije.
Mu bushakashatsi buri gukorwa, itsinda rya RMIT ryavuje uturemangingo tw’umubiri w’umuntu hakoreshejwe ibinyabutabire bya phenolic na aside hydroxycitric mbere yuko bihindurwamo uturemangingo tw’ibinure. Mu turemangingo twagaragayemo aside hydroxycitric, nta mpinduka yabonetse mu ngano y’ibinure bya adipocyte. Ku rundi ruhande, uturemangingo twavuwe hakoreshejwe ibinyabutabire bya phenolic twabaga dufite ibinure bike kuri 95% ugereranyije n’utundi turemangingo.
Ubu buryo bwo kuvura umubyibuho ukabije buriho bwibanda ku guhindura imibereho n'imiti. Nubwo imiti igezweho ari myiza, yongera ibyago byo kugira umuvuduko ukabije w'amaraso no kwangiza impyiko n'umwijima. Ibisubizo bigaragaza ko ibikomoka kuri hibiscus bishobora gutanga ingamba zisanzwe ariko zinoze zo kugabanya ibiro.
Ben Adhikari, umwarimu mu kigo cya RMIT cy’ubushakashatsi ku mirire, yagize ati: “Ibinyabutabire bya Hibiscus phenolic bishobora gufasha mu gukora ibiryo byiza, bitari ingirakamaro gusa mu kubuza ikorwa ry’uturemangingo tw’ibinure, ahubwo binarinda ingaruka mbi zitifuzwa z’imiti imwe n’imwe. Ikigo cy’Ubuvumbuzi, mu itangazo ryashyizwe ahagaragara n’abanyamakuru.
Hari ukwiyongera gushishikazwa no kwiga ibyiza by’imiti ya polyphenolic ikungahaye kuri antioxydants ku buzima. Iboneka mu moko menshi y’imbuto n’imboga. Iyo abantu bayiriye, antioxydants zikuraho uturemangingo twangiza umubiri tugira uruhare mu gusaza no kurwara indwara zidakira.
Ubushakashatsi bwakozwe mbere kuri polyphenols ziri muri hibiscus bwagaragaje ko zigira uruhare mu gukumira enzyme karemano, kimwe n'imiti imwe n'imwe irwanya umubyibuho ukabije. Polyphenols zihagarika enzyme y'igogora yitwa lipase. Iyi poroteyine igabanya ibinure mo ingano nto kugira ngo amara abashe kubikurura. Ibinure byose birengeje urugero bihinduka uturemangingo tw'ibinure. Iyo ibintu bimwe na bimwe bibuza lipase, ibinure ntibishobora kwinjira mu mubiri, bigatuma binyura mu mubiri nk'imyanda.
“Kubera ko iyi miti ya polyphenolic ikomoka ku bimera kandi ishobora kuribwa, hagomba kubaho ingaruka mbi nke cyangwa ntizibeho,” uyu ni Manisa Singh, umunyeshuri warangije muri RMIT. Itsinda riteganya gukoresha hibiscus phenolic extract mu biribwa byiza. Abahanga mu by’imirire bashobora no guhindura iyi miti mo udupira dushobora gukoreshwa mu binyobwa biryoshye.
Adhikari yagize ati: “Ibinyabutabire bya phenolic bigabanya ubushyuhe mu buryo bworoshye, bityo gufunga ntibituma bimara igihe kirekire gusa, ahubwo binatuma dushobora kugenzura uburyo birekurwa n’umubiri kandi bikabyinjizwamo. Iyo tudashyizemo ibinyabutabire, bishobora kwangirika mu nda mbere yuko tubibonamo inyungu.”
