The purpose of this study is to produce an antibacterial ointment out of Mango leaves extract and coconut oil. Young mango leaves were gathered and was chopped into small pieces. 50 mL of coconut oil was put in a frying pan. Then, the chopped mango leaves was added to the coconut oil. It was mixed for 10 minutes. Next, the small bits of mango leaves were removed from the coconut oil. Lastly, candle wax was added to the mixture. It was stirred again thoroughly. The solution was transferred into an empty container and left to cool down. The mango leaves extract with coconut oil was tested at the Bureau of Plant Industry. It was tested against the bacteria E. coli and S. aureus. The resulting Numerical value was 2.5 for E. coli and 3.0 for S. aureus. The bureau used the standard parameter 1-2- slightly inhibited and 3-5 as partially inhibited. Thus, the inhibition of the mango leaves extract and coconut oil in E. coli was slight and it is partial in S. aureus. The researcher concluded that mango leaves extract with coconut oil can kill bacteria like E. coli and S. aureus. It can also be concluded that it can help wounds heal faster because of its antibacterial property.

Chapter I
Background of the Study

The Philippines have many different herbal plants that can cure different illness like body pain, toothache, arthritis, and other diseases. The herbal plants we have contain helpful constituents and properties that can cure different kinds of diseases. We can make useful product made from these plant and other materials.

Nowadays, many herbal plants are being discovered with more uses. Many companies used herbal plants to make ointments, tablets, coffee or teas. Ointments are very useful in treating different kind of wounds. The production of ointments from herbal plants found in our country can help us minimize our dependence on the use of high – cost ointments. The herbal plant must have anti-inflammatory, anti-allergenic and antibacterial properties to produce an effective ointment.

Most of the wounds are infected by the common bacteria like Escherichia coli. As the wounds go deeper and become more complex they can infect the underlying muscles and bone causing osteomyelitis. Coliforms and anaerobes are associated with osteomyelitis in those people who have infected wounds. You also see the bacteria Staphylococcus aureus in the infected wound. Local factors that increase chances of wound infection are having large wound area, increased wound depth, degree of chronicity, the body, necrotic tissue, and mechanism of injury (bites, perforated viscus). (Neal R. Chamberlain. n.d.)

The mango leaves (Mangifera indica) and coconut oil possesses antibacterial activity against different bacteria. (Research Update of Mango and Mango Leaf Extract, n.d.). Coconut and olive oils are traditionally used to moisturize and treat skin infections. Extensive research done by scientists such as Jon J Kabara, PhD, has shown that the Lauric acid found in Coconut Oil is a potent antimicrobial agent . Lauric acid is a major component (49%) of Coconut oil. It has also been found to kill the H. Pylori bacteria in the stomach which are responsible for many stomach problems such as ulcers. The good thing about Lauric acid is that it doesn't kill friendly bacteria in the stomach. Antibiotics kill both good and bad bacteria in the stomach and often need to be followed with probiotics such as acidophilus bacteria to replenish friendly bacteria in the gut.

Mangifera indica leaves and coconut oil have anti-bacterial contents which can help remove the infection on the wounds. This study aimed to produce an ointment which can...
