IMELBOURNE, eOstreliya — Esi sityalo serosella sityiwa kakhulu siqulethe ii-antioxidants abaphandi baseOstreliya abakholelwa ukuba zinokunceda ekukhuthazeni ukwehla kobunzima. Ngokutsho kophando olutsha, ii-antioxidants kunye nee-organic acids kwi-hibiscus zinokuthintela ngempumelelo ukwakheka kwee-fat cells. Ukuba namafutha athile kubalulekile ekulawuleni amandla kunye namanqanaba eswekile emzimbeni, kodwa xa kukho amafutha amaninzi kakhulu, umzimba uguqula amafutha angaphezulu abe zii-fat cells ezibizwa ngokuba zii-adipocytes. Xa abantu bevelisa amandla amaninzi ngaphandle kokuwasebenzisa, ii-fat cells ziyanda ngobukhulu nangenani, nto leyo ekhokelela ekutyebeni nasekutyebeni kakhulu.
Kolu phando lwangoku, iqela le-RMIT linyange iiseli zesiqu somntu ngee-phenolic extracts kunye ne-hydroxycitric acid ngaphambi kokuba ziguqulwe zibe ziiseli zamafutha. Kwiiseli ezivezwe kwi-hydroxycitric acid, akukho tshintsho kumxholo wamafutha e-adipocyte olufunyenweyo. Kwelinye icala, iiseli ezinyangwe nge-phenolic extract zazinamafutha angaphantsi ngama-95% kunezinye iiseli.
Unyango lwangoku lokutyeba kakhulu lugxile ekutshintsheni indlela yokuphila kunye namayeza. Nangona amayeza anamhlanje esebenza kakuhle, andisa umngcipheko woxinzelelo lwegazi oluphezulu kunye nomonakalo kwizintso nakwisibindi. Iziphumo zibonisa ukuba izicatshulwa ze-hibiscus phenolic zinokubonelela ngecebo lendalo kodwa elisebenzayo lokulawula ubunzima.
UBen Adhikari, uprofesa kwiZiko le-RMIT loPhando lwezondlo, uthe: “Izicatshulwa ze-Hibiscus phenolic zinokunceda ekwenzeni imveliso yokutya enempilo engapheleli nje ekuthinteleni ukwakheka kweeseli zamafutha, kodwa ikwathintela nemiphumo emibi engafunekiyo yamayeza athile. IZiko leNguqulelo, kwingxelo yabezindaba.
Kukho umdla okhulayo wokufunda ngezibonelelo zempilo zeekhompawundi zepolyphenolic ezityebileyo kwi-antioxidant. Zifumaneka kwiintlobo ezininzi zeziqhamo nemifuno. Xa abantu bezisebenzisa, ii-antioxidants zisusa iimolekyuli ze-oxidative eziyingozi emzimbeni ezinegalelo ekwaluphaleni nasekuguleni okungapheliyo.
Uphando lwangaphambili malunga neepolyphenols kwihibiscus lubonise ukuba zisebenza njengee-enzyme blockers zendalo, ezifana nezinye iindlela zokwelapha ukutyeba kakhulu. Iipolyphenols zivimba i-enzyme yokugaya ukutya ebizwa ngokuba yi-lipase. Le protein iqhekeza amafutha abe ngamanani amancinci ukuze amathumbu akwazi ukuwafunxa. Nawaphi na amafutha agqithisileyo aguqulwa abe ziiseli zamafutha. Xa izinto ezithile zithintela i-lipase, amafutha awanakufunxwa emzimbeni, nto leyo evumela ukuba adlule emzimbeni njengenkunkuma.
“Ngenxa yokuba ezi zinto ziqulathe i-polyphenolic zivela kwizityalo kwaye zinokutyiwa, kufuneka kubekho iziphumo ebezingalindelekanga ezimbalwa okanye zingabikho,” utshilo umbhali okhokelayo uManisa Singh, umfundi ophumelele kwi-RMIT. Iqela liceba ukusebenzisa i-hibiscus phenolic extract ekutyeni okunempilo. Izazinzulu zezondlo zinokuguqula i-extract ibe ziibhola ezinokusetyenziswa kwiziselo ezihlaziyayo.
“Ii-phenolic extracts zinyibilika lula, ngoko ke ukugquma akupheleli nje ekwandiseni ixesha lazo lokuhlala, kodwa kukwasivumela ukuba silawule indlela ezikhutshwa ngayo nezifunxwa ngayo ngumzimba,” utshilo u-Adhikari. “Ukuba asigqumi i-extract, inokuqhekeka esiswini ngaphambi kokuba sifumane inzuzo.”
