Protocatechuic acid CAS 99-50-3 Protocatechuic acid (PCA) o le 3,4-dihydroxybenzoic acid. O se phenolic acid faigofie, o se mea muamua mo le tuʻufaʻatasia o isi molelaʻau lavelave, e pei o le anthocyanin 3-ochemicalbook- β- D-glucoside ma le vanillin. E maua i fuala'au 'aina, fuala'au aina, nati, araisa enaena, pecans, lauti, fugala'au hibiscus ma nisi o vaila'au fa'aSaina.
