Paw paw leaves and the roots are extracted using solvents, n-hexane, ethyl acetate, ethanol and water. The extracts are then assayed for bacterial activity and inhibition of bacterial growth. The result will show that all the extracts except water extraction have antibacterial activity and that the inhibition of bacterial growth has dose dependent. The results also shows that paw paw extracts posses medicinal properties and could be used for the treatment of bacterial infections.
Paw paw (Carica papaya), known in many
communities as one of God’s wonderful gifts to humanity is a native of South America, cultivated there since the Pre Columbian times. It got to Europe about 1690 AD and Asia in the 18thCentury (Anselm, 2000). It is now grown all over Tropical Africa and sometimes used ornamentally in some parts of the world. In many places the leaves have been used as soap. It is known to improve the digestion of proteins and expel worms. The ripe fruits are rich in vitamins A, B. and C. It therefore can be used to cure eye sight, nerves and muscles, and strength then the immune system (Morah, 2009). The seeds are used to expel worms. The unripe paw paw fruit can be used to treat chronic external ulcers or sores.
It is locally used to cure/treat malaria,
diabetes, stomach ulcers, convulsion, asthma, bronchitis, piles, impotence, and the white milky sap of the unripe paw paw contains a high percentage of papain which is used for chronic external ulcers. As a result of these assertions it has become important that the paw paw be thoroughly investigated.
