Loaʻa ka ʻakika Gallic i nā mea kanu e like me ka rhubarb, ka lau nui, a me ka hawthorn.He hui polyphenolic ia i loaʻa ma ke ʻano a he nui nā mea hoʻohana i ka meaʻai, biology, a me nā ʻoihana kemika.
ʻO ka waikawa Gallic kahi waikawa trihydroxybenzoic me ke ʻano C₆H₃CO₂H. Ua helu ʻia ʻo ia ma ke ʻano he phenolic acid.Loaʻa ia i loko o nā gallnuts, sumac, witch hazel, nā lau kī, ka ʻoka ʻoka, a me nā mea kanu ʻē aʻe.He paʻa keʻokeʻo ia, ʻoiai he ʻeleʻele maʻamau nā laʻana ma muli o ka hoʻokahe hapa ʻana.Ua kapa ʻia nā paʻakai a me nā esters o ka gallic acid "gallates".

Noi:
2. Hiki ke ho'ohana 'ia ka waikawa Gallic no ka hana 'ana i nā wahie like 'ole, nā mea ho'opa'a ahi, nā 'īnika polū-'ele'ele a me nā 'ohe.
3. ʻO ka waikawa Gallic he mea hoʻoheheʻe UV, he pale ahi, he semiconductor photoresist material, a hiki ke hana ʻia me ka anti-rust primer a me ka alumini alumini organik.
4.Gallic acid hiki ke hoʻohanaʻia ma keʻano he eikonogen.
Hiki ke hoʻohana 'ia ka 5.Gallic acid ma ke 'ano he analytical reagent no ka 'ike 'ana i nā 'akika inorganic manuahi, dihydroxyacetone, alkaloids a me nā metala.
