I-Phytosterols yizinto ezisebenzayo zemvelo neziphephile ezitholakala kakhulu emafutheni emifino, imbewu, nezinhlamvu. Kunama-phytosterol angaphezu kuka-200 abonakalisiwe, okuhlanganisa -i-sitosterol, i-stigmasterol, njll. Isakhiwo siboniswa emfanekisweni. Ama-Phytosterol abizwa ngokuthi ama-sterol anempilo, afana nesakhiwo se-cholesterol, kodwa angavimbela ukumuncwa kwe-cholesterol emathunjini futhi athinte imetabolism yayo. Iphinde ibe nomthelela wokuvimbela izifo ze-cardiovascular metabolic kanye nomdlavuza. Isibonelo, -i-sitosterol ibizwa ngokuthi ""Inhliziyo{8}}i-sterols yesitshalo esinobungane" ingaphazamisa ukumuncwa kwe-cholesterol futhi ibe nemiphumela elwa{9}}ne-tumor. Ukuhlolwa kufakazele ukuthi inqobo nje uma umthamo ufanelekile, -i-sitosterol ne-stigmasterol zingangena esikhundleni se-cholesterol kuma-liposterols amabili e-themesterols kuma-themesterols amabili. Isigaba sokuziphatha esifana ne-cholesterol futhi sibe nomthelela we-anti{13}}oxidation yama-liposomes Ukusebenzisa -i-sitosterol esikhundleni se-cholesterol ukuze kulungiswe ama-gambogic acid liposomes anezindleko eziphansi kanye{16}}nomjikelezo wesikhathi eside ongcono{16}Izinga le-encapsulation, ukuzinza kanye nokuzala kabusha kwe-quercetin kanye ne-cholesterol etholakala nge-liposome efanelekile} ukukhiqizwa kwezimboni.
