Kumu kūʻai mea kūʻai p-Coumaric acid me CAS 501-98-4
ʻO ka Trans-4-hydroxycinnamic acid kahi ʻano o ka cinnamic acid compound, i hoʻolaha nui ʻia i nā huahana kūlohelohe e like me ka propolis, nā mea kanu a me nā huaʻai, a he antioxidant maoli. ʻO ka mea nui ma ke ʻano o nā esters acid organik, polyglycosides a me nā amides nui i ke ʻano. ʻO ke ʻano 4- hydroxycinnamic acid he keʻokeʻo a i ʻole ka pauka melemele māmā. Hiki ke hoʻoheheʻe ʻia i ka etera wela, ka ethanol wela, hiki ke hoʻoheheʻe ʻia i loko o ka benzene, hiki ʻole ke hoʻoheheʻe ʻia i ka petroleum etera.

ʻO 4-hydroxy-coumarin kahi mea waena o ka anticoagulant rodenticide, 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 ma ka ʻoihana lāʻau lapaʻau a me nā mea ʻala.
ʻO Trans -4- hydroxycinnamic acid ka e-isomer o ka waika p-coumaric, he hydroxyl derivative o ka cinnamic acid a he waiwai antioxidant kona. ʻO ka waikawa Coumaric kahi mea nui o ka lignoscellulose. Ua hōʻike nā haʻawina e hiki i ka p-coumaric acid ke hoʻemi i ka pilikia o ka maʻi kanesa ma o ka hoʻemi ʻana i ka hana ʻana o nā nitrosamines kumu.
