| Nānā nui | arbutin mea he hydroquinone glycoside pūhui, kemika inoa no 4-hydroxyphenyl-d-glucopyranoside (y), i loko o ka hua bear, bilberry a me nā mea kanu ʻē aʻe, he mea hou non-irritating, non-allergic, maoli whitening mea ikaika me ka ikaika like. Loaʻa iā Arbutin ʻelua mau pūʻulu hana a me ka hana i loko o kāna ʻano mole: hoʻokahi he koena glucose; ʻO kekahi pūʻulu hydroxyl phenolic. ʻIke ʻia ke ʻano kino o ka α-arbutin ma ke ʻano he keʻokeʻo i ka pauka hina hina, ʻoi aku ka maʻalahi i ka wai a me ka ethanol. |
| ka pono | ʻOi aku ka maikaʻi o ka α-arbutin i nā ʻōpala i hana ʻia e UV Burns, ʻoi aku ka maikaʻi o ka anti-inflammatory, hoʻoponopono a me ka hopena keʻokeʻo. Hiki ke pale i ka hana a me ka waiho ʻana o ka melanin, wehe i nā kiko a me nā freckles. |
| ʻano hana | ʻO ka hana keʻokeʻo o ka α-arbutin e hoʻopaʻa pololei i ka hana tyrosinase, ma laila e hōʻemi ai i ka hana ʻana o ka melanin, ma mua o ka hoʻohaʻahaʻa ʻana i ka hana melanin ma ke kāohi ʻana i ka ulu ʻana o ka cell a i ʻole tyrosinase gene expression. ʻOiai ʻo ka α-Arbutin he mea ʻoi aku ka maikaʻi a me ka palekana o ka mea keʻokeʻo keʻokeʻo, nui nā hui hoʻonaninani ma ka home a me nā ʻāina ʻē aʻe i hoʻohana i ka α-arbutin ma kahi o β-arbutin i mea hoʻohui keʻokeʻo. |
| Palapala noi | ʻO ka alpha-Arbutin kahi kemika e like me ka arbutin, hiki ke kāohi i ka hana a me ka waiho ʻana o ka melanin, wehe i nā kiko a me nā freckles. Hōʻike nā hopena i hiki i ka arbutin ke kāohi i ka hana o tyrosinase ma kahi haʻahaʻa haʻahaʻa, a ʻoi aku ka maikaʻi o kona hopena pale i ka tyrosinase ma mua o ka arbutin. Hiki ke hoʻohana ʻia ka alpha-arbutin ma ke ʻano he mea keʻokeʻo i nā mea hoʻonaninani. |
| ka hoʻomaʻemaʻe a me ka ʻike | ʻO ka hāpana i loaʻa ma ka hopena ua unuhi muaʻia me ka ethyl acetate, a laila unuhiʻia me ka n-butanol, ua hōʻiliʻiliʻia nā mea hoʻohālike e ka evaporation ma luna o ka rotary evaporator a centrifuged. Ua kālailai ʻia ka supernatant e HPLC a ua hoʻohālikelike ʻia me ka HPLC chromatogram o α-arbutin, inā paha he like ka manawa paʻa o ka hāpana a me ka α-arbutin, a inā paha i loko o ka hāpana he α-Arbutin ka mea i ʻike mua ʻia. Ua ʻike ʻia ka huahana ma hope o ka unuhi ʻana a me ka hoʻomaʻemaʻe ʻana e ke ʻano ion maikaʻi o LC-ESI-MS/MS. Ma ka hoʻohālikelike ʻana i ka nui molekala pili o ka hua α-bear me ka nui molepili pili o ka maʻamau α-arbutin, hiki ke hoʻoholo inā he α-arbutin ka huahana. |
| Hoʻohana | Hiki i ka α-arbutin ke kāohi i ka hana tyrosinase ma kahi haʻahaʻa haʻahaʻa, ʻoi aku ka maikaʻi o kona hopena pale i ka tyrosinase ma mua o ka arbutin. |
