Kumukūʻai Mea Hoʻolako waikawa p-Coumaric me CAS 501-98-4
ʻO ka waikawa Trans-4-hydroxycinnamic kahi ʻano hui waikawa cinnamic, kahi i hoʻolaha nui ʻia i loko o nā huahana kūlohelohe he nui e like me ka propolis, nā mea kanu a me nā huaʻai, a he antioxidant kūlohelohe. ʻO ke ʻano nui ma ke ʻano o nā esters waikawa organik, nā polyglycosides a me nā amides e noho nui ana ma ke ʻano. ʻO ke ʻano 4- hydroxycinnamic acid he pauka keʻokeʻo a melemele paha. Hoʻoheheʻe ʻia i ka ether wela, ethanol wela, hoʻoheheʻe iki ʻia i ka benzene, ʻaʻole hoʻoheheʻe ʻia i ka petroleum ether.
| Mea | Kūlana Maʻamau |
| helehelena | Pauka kokoke keʻokeʻo |
| Hoʻāʻo | ≥99.0% |
| Pohō ma ka maloʻo ʻana | ≤0.50% |
| Koena ma ke ahi ʻana | ≤0.5% |
ʻO 4-hydroxy-coumarin kahi waena o ka rodenticide anticoagulant, rodenticide, bromadiron, bromurin, rodenticide, rodenticide, rodenticide, flurodenticide, tiamurin, cordenticide, etc.
Hiki ke hana ʻia nā lāʻau anticoagulant i ka lāʻau lapaʻau, e like me ka double coumarin ethyl ester a me ketone benzyl coumarin.
Hoʻohana ʻia ma ke ʻano he waena i ka ʻoihana lāʻau lapaʻau a me ka ʻala.
ʻO ka waikawa Trans -4-hydroxycinnamic ka e-isomer o ka waikawa p-coumaric, he hydroxyl derivative ia o ka waikawa cinnamic a he mau waiwai antioxidant. ʻO ka waikawa Coumaric kahi ʻāpana nui o ka lignocellulose. Ua hōʻike ʻia nā haʻawina e hiki i ka waikawa p-coumaric ke hōʻemi i ka pilikia o ka maʻi kanesa ma ka hōʻemi ʻana i ka hoʻokumu ʻia ʻana o nā nitrosamines e hoʻoulu ai i ka maʻi kanesa.
