Abstract

Lamtoro leaf (Leucaena leucocephala (Lam.) de Wit) is one of the plants of the fabaceae family. Lamtoro leaves have properties as antibacterial, antidiabetic, anti-inflammatory, anticancer, anthelmintic and antioxidant. There are secondary metabolites such as flavonoids, alkaloids, tannins and saponins. The purpose of this study was to determine the content of secondary metabolite compounds by phytochemical screening methods and determine the total flavonoid levels of lamtoro leaves (Leucaena leucocephala (Lam.) de Wit) with 70% ethanol solvent and ethyl acetate and find out whether or not there is a difference in total flavonoid levels of lamtoro leaves (Leucaena leucocephala (Lam.) de Wit). This research is an experimental study using maceration method with 70% ethanol solvent and ethyl acetate and phytochemical screening test was carried out.The data obtained were analyzed using a normality test, a homogeneity test followed by an independent T-Test. Lamtoro leaves (Leucaena leucocephala (Lam.) de wit) are positive for flavonoids, alkaloids, tannins and saponins. The moisture content contained in simplisia powder is 4.55%. The flavonoid content of 70% ethanol extract was obtained 5.45% and the total flavonoid content of ethyl acetate extract was obtained 6.94%. Normality test of 70% ethanol extract and ethyl acetate of lamtoro leaves is normally distributed. The independent T-Test resulted in a difference between the total flavonoid levels of 70% ethanol extract and ethyl acetate extract of lamtoro leaves (Leucaena leucocephala (Lam.) de Wit) due to the sign results obtained 0.002< 0.05.
