Psiguadials A and B, two novel sesquiterpenoid-diphenylmethane meroterpenoids with unusual skeletons, along with a pair of known epimers, psidial A and guajadial. Guaijaverin has high potential antiplaque agent by inhibiting the growth of the Streptococcus mutans.

Avicularin and guaijaverin work as urease inhibitors against Helicobacter pylori urease [ 5758 ]. Guava aqueous leaf extract showed anti-trypanosomal properties in rats experimentally infected with Trypanosoma brucei brucei [ 60 ]. They concluded that this plant offers potential for controlling epidemics of cholera. The antimicrobial activity can be linked to the presence of flavonoids extracted from guava leaves [ 6465 ].

Deguchi and Miyazaki [ 66 ] reported that guava leaves infusion not only reduced postprandial glycemia and improved hyperinsulinemia in murine models but also contributed to reduce hypercholesterolemia, hypertriglyceridemia and hypoadiponectinemia in the animals of their study. Rutin and kaempferol found in guava leaves are compounds related to the decrease of HMG-CoA reductase activity in hepatic tissue and improve lipid profiles [ 67 ].

Several studies have shown that aqueous extract of Psidium guajava contains components with LDL-c antiglycation activity, suggesting its contribution to the prevention of neurodegenerative and cardiovascular diseases [ 6970 ]. Other studies have found cardioprotective effects of aqueous extract of P. Ojewole [ 72 ] identified the presence of phenolic compounds in the leaves demonstrating their hypoglycemic and hypotensive effects on diabetic rats treated with aqueous leaf extract.

Singh and Marar [ 74 ] studied the effects of Psidium guajava leaves on the inhibition of the activity intestinal glycosidases related with postprandial hyperglycemia, suggesting its use for the treatment of individuals with type 2 diabetes.
