MELBOURNE, Ostreliya - Isityalo se-rosella esidliwayo kakhulu siqulethe i-antioxidants abaphandi base-Australia bakholelwa ukuba kunokunceda ukukhuthaza ukulahleka kwesisindo. Ngokutsho kwesifundo esitsha, i-antioxidants kunye ne-organic acids kwi-hibiscus inokuthintela ngokufanelekileyo ukubunjwa kweeseli ezinamafutha. Ukuba namafutha athile kubalulekile ekulawuleni amandla kunye namanqanaba eswekile emzimbeni, kodwa xa kukho amanqatha amaninzi, umzimba uguqula amanqatha agqithisileyo abe ziiseli zamafutha ezibizwa ngokuba zii-adipocytes. Xa abantu bevelisa amandla amaninzi ngaphandle kokuwachitha, iiseli ezinamafutha zanda ngobukhulu kunye nenani, okukhokelela ekuzuzeni ubunzima kunye nokukhuluphala.
Kuphononongo lwangoku, iqela le-RMIT liphatha iiseli ze-stem zomntu kunye ne-phenolic extracts kunye ne-hydroxycitric acid ngaphambi kokuba ziguqulwe zibe ngamafutha. Kwiiseli ezivezwe kwi-hydroxycitric acid, akukho tshintsho kumxholo we-adipocyte fat content. Ngakolunye uhlangothi, iiseli eziphathwa nge-phenolic extract ziqulethe i-95% yamafutha angaphantsi kunezinye iiseli.
Unyango lwangoku lokutyeba lujolise kutshintsho lwendlela yokuphila kunye namayeza. Nangona amayeza anamhlanje esebenza kakuhle, anyusa umngcipheko woxinzelelo lwegazi oluphezulu kunye nomonakalo kwizintso nesibindi. Iziphumo zibonisa ukuba i-hibiscus plant phenolic extracts inokubonelela ngesicwangciso sendalo kodwa esisebenzayo sokulawula ubunzima.
U-Ben Adhikari, uprofesa kwi-RMIT Centre for Nutritional Research, wathi: "I-Hibiscus phenolic extracts inokunceda ukudala imveliso yokutya enempilo engasebenziyo kuphela ekuvimbeleni ukubunjwa kweeseli ezinamafutha, kodwa iphinde igweme imiphumo engafunekiyo yamayeza athile. Innovation Centre, kwingxelo yeendaba.
Kukho umdla okhulayo wokufunda ngezibonelelo zempilo ze-antioxidant-rich polyphenolic compounds. Zifumaneka kwiindidi ezininzi zeziqhamo kunye nemifuno. Xa abantu bezisebenzisa, i-antioxidants isusa umzimba weemolekyuli ze-oxidative ezinobungozi ezinegalelo ekwaluphaleni kunye nesifo esingapheliyo.
Uphando lwangaphambili kwi-polyphenols kwi-hibiscus lubonise ukuba lusebenza njenge-block blocker ye-enzyme yendalo, efana namanye amayeza achasene nokutyeba. Iipolyphenols zivimba i-enzyme yokugaya ebizwa ngokuba yi-lipase. Le proteni iqhekeza amafutha abe ngamanani amancinci ukuze amathumbu akwazi ukuwafunxa. Nawaphi na amanqatha angaphezulu aguqulwa abe ngamafutha. Xa izinto ezithile zithintela i-lipase, amanqatha awakwazi ukufunxwa emzimbeni, ewavumela ukuba adlule emzimbeni njengenkunkuma.
"Ngenxa yokuba ezi zixhobo ze-polyphenolic ziphuma kwizityalo kwaye zinokudliwa, kufuneka kube nemiphumo embalwa okanye ingabikho," kusho umbhali okhokelayo uManisa Singh, umfundi ophumelele i-RMIT. Iqela liceba ukusebenzisa i-hibiscus phenolic extract ekudleni okunempilo. Izazinzulu ngezondlo nazo zinokujika isicatshulwa zibe ziibhola ezinokuthi zisetyenziswe kwiziselo ezihlaziyayo.
"I-Phenolic extracts i-oxidize ngokulula, ngoko i-encapsulation ayigcini nje ukwandisa ubomi babo beshelufu, kodwa isivumela ukuba silawule indlela ekhutshwa ngayo kwaye ifakwe ngumzimba," kusho u-Adhikari. "Ukuba asiyifaki isicatshulwa, sinokuqhekeka esiswini ngaphambi kokuba sifumane inzuzo."
