Extraction of Tannin from Psidium guajava Leaves

Sachin Shinde, Akshay Deshmukh, Aishwarya Deshmukh


Psidium guajava leaves are widely used as medicine from ancient times. Leaves are important part of guava tree which are useful in curing many health issues. Guava leaves have properties like anti-cancer, antibacterial, anti-oxidant, antiulcer etc. they are used in curing many diseases. In this article, soxhlet extraction method is discussed and yield of this method is represented. Extraction processes with different solvent such as ethanol, methanol, benzene is discussed in this article. Extract of guajava leaf have antiglycation activity and cure neurodegenerative and cardiovascular disease and also having antiprostate cancer activity. The method used for qualitative analysis with the tannins are formed by the intensity of the color is blackish green FeCl3 compounds. Research has been carried out to determine the levels of tannins in leaves of guava (Psidium guajava L) using a variation of the temperature for extraction.
