One mL of 0.25 M sodium acetate containing 5 mg/mL gentisic acid (pH 5.5) was then added to the reaction solution.
[7], it is apparent that the Rosa rugosa petals also contain other phenolic acids, including caffeic acid, gentisic acid, protocatechuic acid, gallic acid, salicylic acid, sinapinic acid, and p-coumaric acid, which in the studied petals were not found.

Levels of the different compounds were extrapolated from calibration curves prepared individually for each commercial standard in methanol (apigenin, butylated hydroxytoluene (BHT), caffeic acid, catechin, chlorogenic acid, coumaric acid, epicatechin, epigallocatechin, epigallocatechin gallate, ferulic acid, flavone, gallic acid, gentisic acid, 4-hydroxybenzaldehyde, m-hydroxybenzoic acid, p-hydroxybenzoic acid, luteolin, oleanolic acid, quercetin, resveratrol, rosmarinic acid, rutin hydrate, salicylic acid, syringic acid, transcinnamic acid, uvaol, vanillic acid and verbascoside) or ultrapure water (luteolin-7-O-glucoside), at 1.00 mg/L, and diluted to desired concentrations with ultrapure water.
In this paper, we aimed to provide thermodynamical parameters, related to the antiradical mechanism, that can implicate the antioxidant activity of six DHBAs: 2,3-dihydroxybenzoic acid (2-pyrocatechuic acid or hypogallic acid); 2,4-dihydroxybenzoic acid ([beta]-resorcylic acid); 2,5-dihydroxybenzoic acid (gentisic acid); 2,6-dihydroxybenzoic acid (gamma-resorcylic acid or 2,6-resorcylic acid); 3,4dihydroxybenzoic acid (protocatechuic acid), and 3,5-dihydroxybenzoic acid ([alpha]-resorcylic acid) (Figure 1).
The n-BuOH extract contains also a high amount of gallic acid followed by rutin, gentisic acid, salicylic acid, and chlorogenic acid.
salvifolius contain the highest amount of gallic acid with retention time (RT) = 2.051 and gentisic acid, followed by protocatechuic acid.
The bioactive compounds in mango peel extracts recently identified by HPLC were protocatechuic acid, gentisic acid and gallic acid, syringic acid, mangiferin, ellagic acid, gentisyl-protocatechuic acid and quercetin in both raw and ripe peels.
