Plant Content
Guava is rich in tannins, phenols, triterpenes, flavonoids, essential oils, saponins, carotenoids, lectins, vitamins, fiber and fatty acids. Guava fruit is higher in vitamin C than oranges (80 mg of vitamin C in 100 g of fruit) and contains an adequate amount of vitamin A as well. Guava fruit is also a good source of pectin – dietary fiber. Guava leaves are rich in flavonoids, in particular, quercetin. Many of these guava therapeutic activities are associated with the flavonoid. Flavonoids have demonstrated antibacterial activity. Quercetin is thought to contribute to the effects of guava anti-diarrhea; it is able to relax the intestinal smooth muscles and inhibit intestinal contractions.
