This analysis showed that guava is high in many vitamins, essential amino acids, soluble fibers, minerals, and other important organic compounds like carotene and lycopene.
All the parts of guava including leaves, bark, fruits, and root are shown to be beneficial to animals’ health.
The leaves, bark, and unripe fruits contain tannin. The tannin that is present in leaves is about 10% as measured in dry weight while that of bark is about 11 to 30%.
in addition to the tannin content of guava leaves, the leaves also have abundant essential oil that is also rich in sesquiterpene hydrocarbons caryophyllene, b-bisabolene, aromadendrene, b-selinene, nerolidol, caryophyllene oxide, and sel-11-en-4x -ol, also some triterpenoids and b-sitosterol (source).
On the other hand, the bark contains ellagic acid, crystals of calcium oxalate, and starch.
