Ko te waikawa Protocatechuic CAS 99-50-3 Ko te waikawa Protocatechuic (PCA) he waikawa 3,4-dihydroxybenzoic. He waikawa phenolic ngawari, he tohu mo te whakahiato o etahi atu ngota ngota uaua, penei i te anthocyanin 3-ochemicalbook- β- D-glucoside me te vanillin. Ka kitea i roto i nga huawhenua kai, hua, nati, raihi parauri, pekani, ti, puawai hibiscus me etahi rongoa rongoa Hainamana.
