MELBOURNE, Australia - Isitshalo se-rosella esidliwa kakhulu siqukethe ama-antioxidants abacwaningi base-Australia abakholelwa ukuthi angasiza ekunciphiseni isisindo. Ngokusho kocwaningo olusha, ama-antioxidants nama-organic acid e-hibiscus angavimbela ngokuphumelelayo ukwakheka kwamangqamuzana amafutha. Ukuba namafutha athile kubalulekile ekulawuleni izinga lamandla kanye noshukela emzimbeni, kodwa uma kunamafutha amaningi, umzimba uguqula amafutha eqile abe amangqamuzana amafutha abizwa ngokuthi ama-adipocytes. Lapho abantu bekhiqiza amandla engeziwe ngaphandle kokuwachitha, amangqamuzana amafutha anda ngosayizi nenombolo, okuholela ekuzuzeni isisindo nokukhuluphala.
Ocwaningweni lwamanje, ithimba le-RMIT liphathe amangqamuzana esiqu somuntu nge-phenolic extracts kanye ne-hydroxycitric acid ngaphambi kokuba aguqulwe abe amaseli amafutha. Kumaseli avezwe ku-hydroxycitric acid, alukho ushintsho kumafutha e-adipocyte olutholakele. Ngakolunye uhlangothi, amaseli aphathwe nge-phenolic extract aqukethe amafutha angaphansi kwama-95% kunamanye amaseli.
Ukwelashwa kwamanje kokukhuluphala kugxile ekushintsheni indlela yokuphila kanye nemithi. Nakuba imithi yesimanje isebenza ngempumelelo, yandisa ingozi yomfutho wegazi ophakeme kanye nokulimala kwezinso nesibindi. Imiphumela ibonisa ukuthi i-hibiscus plant phenolic extracts ingase inikeze isu lemvelo kodwa elisebenzayo lokulawula isisindo.
U-Ben Adhikari, uprofesa e-RMIT Centre for Nutritional Research, uthe: "I-Hibiscus phenolic extracts ingasiza ekudaleni umkhiqizo wokudla onempilo ongasebenzi nje kuphela ekuvimbeleni ukwakheka kwamangqamuzana amafutha, kodwa futhi ugwema imiphumela emibi engadingeki yemithi ethile. I-Innovation Center, ekukhululweni kwabezindaba.
Kunentshisekelo ekhulayo yokutadisha izinzuzo zezempilo ze-antioxidant-rich polyphenolic compounds. Zitholakala ezinhlotsheni eziningi zezithelo nemifino. Lapho abantu bewadla, ama-antioxidants akhipha ama-molecule ayingozi e-oxidative anomthelela ekugugeni nasekuguleni okungamahlalakhona.
Ucwaningo lwangaphambilini lwama-polyphenols ku-hibiscus lubonise ukuthi asebenza njengezivimbeli ze-enzyme zemvelo, ezifana neminye imithi elwa nokukhuluphala ngokweqile. Ama-polyphenols avimba i-enzyme yokugaya ebizwa ngokuthi i-lipase. Le phrotheni iphula amafutha abe ngamanani amancane ukuze amathumbu akwazi ukuwamunca. Noma yimaphi amafutha amaningi aguqulwa abe ama-fat cells. Lapho izinto ezithile zivimbela i-lipase, amafutha awakwazi ukumuncwa emzimbeni, okuwavumela ukuba adlule emzimbeni njengemfucuza.
"Ngenxa yokuthi lezi zinhlanganisela ze-polyphenolic zitholakala ezitshalweni futhi zingadliwa, kufanele kube nemiphumela emibi embalwa noma ingabi khona," kusho umlobi oholayo uManisa Singh, umfundi ophothule i-RMIT. Ithimba lihlela ukusebenzisa i-hibiscus phenolic extract ekudleni okunempilo. Ososayensi bokudla okunomsoco bangakwazi futhi ukuguqula i-extract ibe amabhola angasetshenziswa eziphuzweni eziqabulayo.
"I-Phenolic extracts i-oxidize kalula, ngakho-ke i-encapsulation ayigcini nje ukwandisa impilo yabo yeshalofu, kodwa futhi isivumela ukuthi silawule ukuthi zikhishwa kanjani futhi zifakwe emzimbeni," kusho u-Adhikari. "Uma singayihlanganisi i-extract, ingaphuka esiswini ngaphambi kokuba sizuze."

UJocelyn uhlanganisa izihloko eziningi zezokwelapha nezesayensi, kusukela ezindabeni ze-coronavirus kuya kokutholwe kwakamuva kwezempilo yabesifazane.
