“…There are many compounds identified in propolis samples that have gastroprotective activity in NSAIDs-induced gastric ulcer models, principally from Brazilian (green and red) propolis, and North Mexican propolis, as shown in Table 2 ; among all these phenolic compounds, some have been reported with gastroprotective effects such as caffeic acid, ferulic acid, cinnamic acid, p -coumaric acid, artepillin C, Kaempferide, 7-O-methylvestitol, aromadendrine-4′-O-methyl ether, formononetin, biochanin A, medicarpine, apigenin, catechin, kaempferol, naringin, and naringenin [ 53 , 54 , 59 , 63 , 68 , 70 , 76 , 88 , 92 , 93 , 94 , 95 , 96 , 98 , 126 , 127 , 128 , 153 , 154 ] or activities related to gastroprotective effects; between them, most classes of phenolic compounds related to the gastroprotective activity of propolis are flavonoids, that include principally five subclasses of this type of compounds (flavonols, isoflavonoids, flavanones, flavones, and a flavanonol) and, phenolic acids, among them compounds derivate of cinnamic acid; and finally, some simple phenols that have been reported with gastroprotective activity as the anethole, catechol and methyl eugenol ( Figure 4 ). Nevertheless, the gastroprotective-related activities of all the phenolic compounds in these propolis samples have not been evaluated.…”
