Jackfruit leaves are one of the medical plants that have many benefits. In general, jackfruit leaves are known as animal feed, but behind their function as animal feed, jackfruit leaves have health benefits because jackfruit leaves contain antimicrobials including flavonoids, tannins, saponins that can dissolve in water and can work to damage cytoplasmic membranes and denature cell proteins bacteria. Staphylococcus aureus is a gram-positive bacterium and is arranged in clusters (like grapes). Some infectious diseases caused by these bacteria are impetigo, boils, acne, wound infections, toxic shock syndrome, and other types of pathogenic. This study was conducted to determine the effect of jackfruit leaf extract dissolved using 70% ethanol as a solvent on the growth of staphylococcus aureus bacteria. The method used is the maceration method for the phytochemical screening test, and the disc diffusion method for the antibacterial activity test. The results of the phytochemical screening contained secondary metabolite compounds in jackfruit leaves and for the results of the antibacterial activity test of jackfruit leaf ethanol extract against the growth of staphylococcus aureus bacteria there was antibacterial activity inhibition with high inhibition at 80% concentration with a diameter of 13mm.

Fragrant pandanus is a type of monocot plant from the pandanaceae family. Fragrant pandan leaves have various ingredients and can be used as antibacterial ingredients and are safe to use, which have been known empirically by the Indonesian people. There are many benefits to the fragrant pandan leaf plant (Pandanus amaryllifolius Roxb), namely as an analgesic (toothache medicine) and antibacterial. The purpose of this study was to determine the chemical content, formulation and stability test in mouthwash preparations. In this study, the maceration method is used which is used to filter simplicia containing chemical components that are easily soluble in liquid. The results of this study indicate that in the phytochemical screening test there are chemical compounds which include flavonoids, alkaloids, saponins, and tannins, which are thought to have contributed to bacterial activity. Research has also been carried out on the formulation and stability test of mouthwash preparations from the ethanol extract of pandan fragrant  leaves  (Pandanus  amaryllifolius roxb)  where  the  results  show  that  the  formulation  can  be  used  as mouthwash of fragrant pandan leaves (Pandanus amaryllifolius roxb) with different concentrations in formulation I. as much as 15.5%, in formulation II as much as 16.5%, and in formulation III 17.5%. And the physical quality test of the mouthwash includes an organoleptic test which has a distinctive smell of fragrant pandan leaves and menthol and the pH test has a stable pH of 5. The results obtained basically produce mouthwash with good physical quality.
