MELBOURNE, Australia — Cov nroj tsuag rosella uas noj tau zoo muaj cov tshuaj antioxidants uas cov kws tshawb fawb Australian ntseeg tias yuav pab txhawb kev poob phaus. Raws li kev tshawb fawb tshiab, cov tshuaj antioxidants thiab cov organic acids hauv hibiscus tuaj yeem tiv thaiv kev tsim cov hlwb rog. Muaj qee cov rog yog qhov tseem ceeb rau kev tswj hwm lub zog thiab cov piam thaj hauv lub cev, tab sis thaum muaj rog ntau dhau, lub cev hloov cov rog ntau dhau mus ua cov hlwb rog hu ua adipocytes. Thaum tib neeg tsim ntau lub zog yam tsis siv nws, cov hlwb rog nce ntxiv thiab ntau ntxiv, ua rau hnyav nce thiab rog dhau.
Hauv kev tshawb fawb tam sim no, pab pawg RMIT tau kho cov hlwb tib neeg nrog cov phenolic extracts thiab hydroxycitric acid ua ntej lawv hloov mus ua cov hlwb rog. Hauv cov hlwb uas raug hydroxycitric acid, tsis muaj kev hloov pauv ntawm cov rog adipocyte. Ntawm qhov tod tes, cov hlwb kho nrog phenolic extract muaj 95% rog tsawg dua li lwm cov hlwb.
Cov kev kho mob tam sim no rau kev rog dhau yog tsom mus rau kev hloov pauv hauv lub neej thiab tshuaj. Txawm hais tias cov tshuaj niaj hnub no muaj txiaj ntsig zoo, lawv ua rau muaj kev pheej hmoo ntawm kev ntshav siab thiab kev puas tsuaj rau lub raum thiab lub siab. Cov txiaj ntsig qhia tau hais tias cov tshuaj phenolic ntawm cov nroj tsuag hibiscus yuav muab cov tswv yim tswj qhov hnyav ntuj tab sis zoo.
Ben Adhikari, tus xibfwb ntawm RMIT Center for Nutritional Research, tau hais tias: "Cov tshuaj Hibiscus phenolic extracts tuaj yeem pab tsim cov khoom noj khoom haus zoo uas tsis yog tsuas yog ua tau zoo hauv kev tiv thaiv kev tsim cov hlwb rog, tab sis kuj zam kev phiv tsis xav tau ntawm qee cov tshuaj. Innovation Center, hauv tsab xov xwm tshaj tawm.
Muaj kev txaus siab rau kev kawm txog cov txiaj ntsig kev noj qab haus huv ntawm cov tshuaj polyphenolic uas muaj antioxidant ntau. Lawv pom muaj nyob rau hauv ntau hom txiv hmab txiv ntoo thiab zaub. Thaum tib neeg noj lawv, cov antioxidants tshem tawm lub cev ntawm cov tshuaj oxidative uas ua rau lub cev laus thiab muaj kab mob ntev.
Cov kev tshawb fawb yav dhau los txog cov polyphenols hauv hibiscus tau qhia tias lawv ua haujlwm ua cov enzyme blockers ntuj, zoo ib yam li qee cov tshuaj tiv thaiv kev rog dhau. Polyphenols thaiv ib qho enzyme zom zaub mov hu ua lipase. Cov protein no rhuav cov rog ua cov khoom me me kom cov hnyuv tuaj yeem nqus tau lawv. Cov rog ntau dhau yuav hloov mus ua cov hlwb rog. Thaum qee cov tshuaj inhibit lipase, cov rog tsis tuaj yeem nqus tau rau hauv lub cev, cia nws hla dhau lub cev ua pov tseg.
"Vim tias cov tshuaj polyphenolic no yog los ntawm cov nroj tsuag thiab noj tau, yuav tsum muaj tsawg dua lossis tsis muaj kev phiv," tus sau thawj coj Manisa Singh, tus tub ntxhais kawm tiav qib siab RMIT hais. Pab neeg npaj yuav siv cov tshuaj hibiscus phenolic extract hauv cov zaub mov noj qab haus huv. Cov kws tshawb fawb txog kev noj haus kuj tseem tuaj yeem tig cov tshuaj rho tawm mus ua cov pob uas tuaj yeem siv rau hauv cov dej haus txias.
"Cov tshuaj phenolic extracts yooj yim oxidize, yog li encapsulation tsis yog tsuas yog ua rau lawv lub txee ntev dua xwb, tab sis kuj tseem tso cai rau peb tswj hwm seb lawv raug tso tawm thiab nqus los ntawm lub cev li cas," Adhikari hais. "Yog tias peb tsis encapsulate cov extract, nws tuaj yeem tawg hauv plab ua ntej peb tau txais txiaj ntsig."

Nws muaj daim ntawv kawm tiav qib master hauv kev puas siab puas ntsws hauv kev coj cwj pwm thiab daim ntawv kawm tiav qib bachelor hauv kev sib koom ua ke ntawm lub paj hlwb los ntawm Binghamton University. Jocelyn npog ntau yam kev kho mob thiab kev tshawb fawb, los ntawm xov xwm coronavirus mus rau cov kev tshawb pom tshiab hauv kev noj qab haus huv ntawm cov poj niam.
