Abstract
Biloba ginkgo leaves are one of the most popular herbal medicines. The purpose of this study was to use ginkgo Biloba leaf extracts to find out how many free amino acids are in a sample. Phenolic compounds, particularly flavonoids, were estimated in the two types of extracts using the high-performance liquid chromatography device (HPLC) and many other important biologically active factors due to their benefits to human health and antioxidant and antibacterial effects. Aqueous extracts and ethanol showed nine types of amino acids, the highest of which was cysteine. In addition to containing good numbers and quantities of phenolic compounds, many of which contain multiple biological properties such as antioxidant and antibacterial, this research has been carried out. An antioxidant analysis showed that ethanol extract showed more antioxidant properties than aqueous extract. However, compared to vitamin C measurement, both extract sections were able to inhibit a good ratio of 1, 1- diphenyl 2-picrylhydrazyl free radical (DPPH) with a good excellent ratio balance. The maximum activity of DPPH root rickets for vitamin C (69.4) ppm, ethanol extract (185.58) ppm, and aqueous extraction (251) ppm were concentrated. The antibacterial activity showed a maximum inhibition area of 24 mm for Staphylococcus aureus as Shigella flexneri at a concentration of 500 ppm.
