IMELBOURNE, e-Australia — Lesi sitshalo se-rosella esidliwa kakhulu siqukethe ama-antioxidants abacwaningi base-Australia abakholelwa ukuthi angasiza ekukhuthazeni ukwehla kwesisindo. Ngokusho kocwaningo olusha, ama-antioxidants nama-organic acid ku-hibiscus kungavimbela ngempumelelo ukwakheka kwama-fat cell. Ukuba namafutha athile kubalulekile ekulawuleni amandla kanye namazinga kashukela emzimbeni, kodwa uma kunamafutha amaningi kakhulu, umzimba uguqula amafutha angaphezulu abe ama-fat cell abizwa ngokuthi ama-adipocytes. Lapho abantu bekhiqiza amandla engeziwe ngaphandle kokuwasebenzisa, ama-fat cell ayanda ngobukhulu nangenani, okuholela ekukhuleni kwesisindo kanye nokukhuluphala ngokweqile.
Ocwaningweni lwamanje, ithimba le-RMIT lelaphe amaseli e-stem abantu ngezithako ze-phenolic kanye ne-hydroxycitric acid ngaphambi kokuba aguqulwe abe amaseli amafutha. Emaseli atholakale ku-hydroxycitric acid, akukho shintsho olutholakale kokuqukethwe kwamafutha e-adipocyte. Ngakolunye uhlangothi, amaseli aphathwe nge-phenolic extract ayenamafutha angaphansi ngo-95% kunamanye amaseli.
Izindlela zokwelapha ukukhuluphala kwamanje zigxile ekushintsheni indlela yokuphila kanye nemithi. Nakuba imithi yesimanje isebenza kahle, yandisa ingozi yomfutho wegazi ophakeme kanye nomonakalo ezinso nasesibindini. Imiphumela ikhombisa ukuthi izithasiselo ze-hibiscus plant phenolic zingase zinikeze isu lemvelo kodwa eliphumelelayo lokulawula isisindo.
UBen Adhikari, uprofesa e-RMIT Center for Nutritional Research, uthe: “Izicucu ze-Hibiscus phenolic zingasiza ekwakheni umkhiqizo wokudla onempilo ongagcini nje ngokuvimbela ukwakheka kwamaseli amafutha, kodwa futhi ogwema imiphumela emibi engafuneki yemithi ethile. Isikhungo Sokusungula Izinto Ezintsha, esitatimendeni sabezindaba.
Kunesithakazelo esikhulayo sokufunda ngezinzuzo zezempilo zama-polyphenolic compounds acebile ngama-antioxidant. Atholakala ezinhlotsheni eziningi zezithelo nemifino. Uma abantu bezidla, ama-antioxidants asusa ama-molecule e-oxidative ayingozi emzimbeni abangela ukuguga nezifo ezingamahlalakhona.
Ucwaningo lwangaphambilini ngama-polyphenols ku-hibiscus lukhombisile ukuthi asebenza njengezithiyo zemvelo zama-enzyme, njengeminye imithi yokulwa nokukhuluphala. Ama-polyphenols avimba i-enzyme yokugaya ukudla ebizwa ngokuthi i-lipase. Le phrotheni iphula amafutha abe ngamanani amancane ukuze amathumbu akwazi ukuwamunca. Noma yimaphi amafutha angaphezulu aguqulwa abe amaseli amafutha. Uma izinto ezithile zivimbela i-lipase, amafutha awakwazi ukumuncwa emzimbeni, okuwenza adlule emzimbeni njengemfucuza.
“Ngenxa yokuthi la ma-polyphenolic compounds atholakala ezitshalweni futhi angadliwa, kufanele kube nemiphumela emibi embalwa noma ingabi bikho,” kusho umlobi oholayo uManisa Singh, umfundi ophothule i-RMIT. Ithimba lihlela ukusebenzisa i-hibiscus phenolic extract ekudleni okunempilo. Ososayensi bezokudla okunempilo bangaguqula i-extract ibe amabhola angasetshenziswa eziphuzweni eziqabulayo.
“Izicucu ze-phenolic zikhipha kalula i-oxidize, ngakho-ke ukufakwa kwezicucu akugcini nje ngokwandisa isikhathi sazo sokuphila, kodwa futhi kusenza sikwazi ukulawula indlela ezikhishwa futhi zimuncwe ngayo ngumzimba,” kusho u-Adhikari. “Uma singazifaki izicucu, zingaphuka esiswini ngaphambi kokuba sithole inzuzo.”
