Ojiji
Asịd gallic (GA), nke a makwaara dị ka gallnut acid, bụ ihe mejupụtara tannins ndị a na-enweta hydrolyzable ma nwee aha kemịkalụ 3,4, 5-trihydroxybenzoic acid. Gallic acid nwere nnukwu ọdịnaya dị na tii Yunnan Pu 'er ma n'onwe ya nwere ọtụtụ mmetụta dị ndụ dịka nje bacteria, mgbochi mkpali, mgbochi etuto na mgbochi mutagenic.
A na-eji Gallic acid eme ihe n'ọtụtụ ọgwụ, ink, agba, nri, ụlọ ọrụ ọkụ na mmepụta ihe ndị sitere n'okike, wdg. Gallic acid na-emeghachi omume na ion ígwè trivalent iji mepụta ihe na-eme ka ọ bụrụ ihe na-acha anụnụ anụnụ na oji, nke bụ ihe e ji eme ink ojii-acha anụnụ anụnụ.
