Zingiber officinale (Ginger) is known to have repellent properties that can be used to repel mosquitoes. Meanwhile, Aloe barbadensis Miller (Aloe Vera) is applied on the skin because of its various uses; however, little is known about its antibacterial properties. This study aims to identify the presence of antibacterial and repellent properties of aloe vera, ginger, and its mixture through phytochemical analysis. Phytochemical analyses were conducted on ginger, aloe vera, and its mixture extracts to identify the different substances present on the plant extracts. Extracts from Ginger and Aloe vera were sent to the Department of Science and Technology to test the presence of antibacterial properties (saponins, glycosides, tannins, and alkaloids) in aloe vera and the presence of repellent properties (sterols, flavonoids, and triterpenes) in ginger. Phytochemical analyses would indicate a positive and negative result on whether the aforementioned constituents are present on the said extracts. The results showed 100% presence on all extracts, concluding that all seven constituents are present in aloe vera, ginger, and its extract mixture. This study may be used as a basis in creating antibacterial and repellent products and test their effectiveness and safety.
