Natural remedies were employed long before the development of modern medicines. For thousands of years, humans have relied on medicines made from plants and animals to combat illness and infection. A phytochemical is the component that drives all of this activity and it is the one accountable for all of this. The phytochemicals in Averrhoa carambola are the primary focus of this study. During the phytochemical analysis, it is found that Averrhoa carambola leaves consist of different kinds of alkaloids, flavonoids, steroid, tannins and caroternoid. The best solvent for plant extraction was hot water, followed by cold water, even though flavonoids could not be extracted from the leaf extracts. Although there was no statistically significant difference between the amounts of alkaloids in extracts made from washed and unwashed leaves, the former contained somewhat more alkaloids (7.32% in hot water extracts and 6.83% in cold water extracts from washed leaves) than the latter (6.12% in hot water extracts and 5.32% in cold water extracts from unwashed leaves). The flavonoids in bitter leaf were released by both ethanolic and hot water extracts. Both extracts were used to identify carotenoid pigments, but the amounts were so similar as to be negligible. The research confirmed that bitter leaf contains antibacterial activity.
