Fa'atauga Tau p-Coumaric acid ma CAS 501-98-4
Trans-4-hydroxycinnamic acid o se ituaiga o cinnamic acid compound, lea e faʻasalalau lautele i le tele o oloa faʻanatura e pei o propolis, fualaau faisua ma fualaau aina, ma o se antioxidant masani. E masani lava i foliga o esters acid organic, polyglycosides ma amides lautele o loʻo i ai i le natura. Uiga 4- hydroxycinnamic acid e pa'epa'e po'o le pa'u samasama mama. Solu i le eter vevela, ethanol vevela, soluble teisi i le benzene, e le mafai ona solu i le suauu eter.

4-hydroxy-coumarin o se vaeluaga ole anticoagulant rodenticide, rodenticide, bromadiron, bromurin, rodenticide, rodenticide, rodenticide, flurodenticide, tiamurin, cordenticide, ma isi.
O vailaʻau faʻamaʻi e mafai ona faia i vailaʻau, e pei o le double coumarin ethyl ester ma le ketone benzyl coumarin.
Faʻaaogaina e avea o se mea faʻapitoa i vailaʻau ma mea manogi.
Trans -4- hydroxycinnamic acid o le e-isomer o le p-coumaric acid, o se mea e maua mai i le hydroxyl o le cinnamic acid ma o loʻo i ai mea faʻapitoa. Coumaric acid o se vaega tele o le lignoscellulose. O suʻesuʻega ua faʻaalia ai e mafai e le p-coumaric acid ona faʻaitiitia le lamatiaga o le kanesa e ala i le faʻaitiitia o le fausiaina o nitrosamines e mafua ai le kanesa.
