Ojiji
1. A na-eji ya eme ihe ịchọ mma n'ụlọ ọrụ mmepụta ihe ịchọ mma: kojic acid nwere ike igbochi mmepụta nke tyrosinase, yabụ ọ nwere ike igbochi mmepụta melanin n'akpụkpọ ahụ nke ukwuu, ọ dịkwa mma ma ghara imebi ahụ, ọ gaghịkwa emepụta ihe na-esochi vitiligo, yabụ agwakọtara kojic acid n'ime ude mmiri, ihe mkpuchi ihu, ude mmiri, ude akpụkpọ ahụ, ma mee ya ka ọ bụrụ ihe ịchọ mma na-acha ọcha nke nwere ike ịgwọ ntụpọ, ntụpọ afọ, agba, ihe otutu, wdg. Ọnụọgụ nke 20ug/ml kojic acid nwere ike igbochi 70 ~ 80% nke ọrụ nke ọtụtụ tyrosinase (ma ọ bụ polyphenol oxidase PPO), na ọnụọgụ mgbakwunye izugbe na ihe ịchọ mma bụ 0.5 ~ 2.0%.
2. A na-eji ya eme ihe n'ịhazi nri: enwere ike iji kojic acid dị ka ihe mgbakwunye nri iji rụọ ọrụ nke nchekwa, ọgwụ nje na antioxidant. Nnwale egosila na kojic acid nwere ike igbochi ntụgharị nke sodium nitrite ka ọ bụrụ nitrosamines kansa n'ime anụ anwụrụ ọkụ, mgbakwunye nke kojic acid na nri agaghị emetụta uto, isi na udidi nke nri. Kojic acid bụkwa ihe e ji emepụta maltol na ethyl maltol, a na-ejikwa ya nke ukwuu na nhazi nri.
3. A na-eji ya eme ihe maka ọgwụgwọ: n'ihi na kojic acid enweghị mmetụta mutagenic na mkpụrụ ndụ eukaryotic, ọ nwekwara ike iwepụ ihe ndị na-emebi emebi n'ime ahụ mmadụ, mee ka mkpụrụ ndụ ọbara ọcha dịkwuo mma, wdg, nke bara uru maka ahụike mmadụ, yabụ ejirila kojic acid mee ihe dị ka ihe eji eme ọgwụ nje cephalosporin, a na-ejikwa ọgwụ emechara emepụta ya agwọ isi ọwụwa, mgbu ezé na mbufụt mpaghara na ọrịa ndị ọzọ, mmetụta mgbu na mgbochi mbufụt dịkwa mma nke ukwuu.
4. Ọgwụ nje ndị e ji arụ ọrụ ugbo: enwere ike iji kojic acid mepụta ọgwụ nje ndị dị ndụ. Ngwakọta nje bacteria (mmiri uhie gbara ọchịchịrị) nke e ji 0.5 ~ 1.0% kojic acid mee, ma a na-efesa ya dị ka fatịlaịza akwụkwọ nri na obere mkpokọta, ma ọ bụ mee ka ọ bụrụ ihe na-eme ka mkpụrụ osisi too maka itinye mgbọrọgwụ, onye na-akwalite mmepụta ihe ubi a nwere mmetụta mmụba mkpụrụ na ọka na akwụkwọ nri.
