| Abstract | Crinum asiaticum L. leaves are medicinal plants that have been traditionally used to treat various diseases, including rheumatism. Phytochemical screening was conducted to identify the groups of secondary metabolites present in the plant. The phytochemical screening of Crinum asiaticum L. leaves included tests for alkaloids,steroids/triterpenoids,saponins,tannins, polyphenols,glycosides, and flavonoids. Crinum Asiaticum L leaves containes alkaloids, triterpenoids, saponins, tannins, and flavonoids. This study consisted of plant material preparation, extraction using 70% ethanol and ethyl acetate, characterization, phytochemical screening, and determination of total flavonoid content in the ethanol and ethyl acetate extracts of Crinum asiaticum L. leaves using the UV-Visible spectrophotometric method. The extracts were prepared by maceration using 70% ethanol and ethyl acetate as extraction solvents, followed by concentration using a rotary evaporator. The total flavonoid content was then determined using the UV-Visible spectrophotometric method. The phytochemical screening results indicated that both the ethanol and ethyl acetate extracts contained alkaloids, flavonoids, saponins, tannins, and steroids/triterpenoids. The total flavonoid content of the ethanol extract was 6.5149 - 0.0314 mg QE/g extract, while the ethyl acetate extract showed a higher total flavonoid content of 7.7674 ‡ 0.1199 mg QE/g extract.It is recommended that further research be conducted to develop Crinum leaf extract into pharmaceutical formulations, as well as to evaluate its efficacy and safety using animal models. In addition, the exploration of various extraction solvents is suggested to obtain more optimal active compounds and biological activity.
