Abstract

Sesbania Grandiflora .L is a type of plant that has so many benefits in the treatment of various kinds Diseases include laxatives, pain relievers (analgesics), fever reducers (antipyretic), laxative urine (diuretic), and others. Almost all parts of This plant belonging to the genus Sesbania Grandiflora is efficacious as a medicine covering the skin stems, flowers, leaves and roots. Sesbania Grandiflora .L  contains alkaloid compounds, glycosides, flavonoids, saponins, tannins and phenols which give a positive reaction in the phytochemical screening assay. Turi leaf extract need to be made in the form of pharmaceutical dosage forms for ease of use. One preparation that can be applied is a suspension.In this study, turi leaf extract was used as the active substance. The suspension was made in 3 formulas with different concentrations of turi leaf extract. The finished suspension was tested for physical characteristics including organoleptic test, homogeneity test, pH test, density test and viscosity test.Based on the results of secondary metabolite tests, turi leaves contain alkaloids, flavonoids, tannins and saponins. Based on the results of testing the physical properties of the suspension, it showed that all formulas met SNI standards based on organoleptic, homogeneity, pH and density tests. while based on the viscosity test the suspension made does not meet SNI standards.

Abstract

Research has been carried out on manufacturing liquid soap silver nanoparticles of Turi leaf extract. Ag nanoparticles have been used in various cosmetic and personal care products. This is because Ag nanoparticles have potential advantages such as increasing product stability, increasing absorption, and the ability to give special effects to the skin. From the physical properties test results, all soap formulas meet the standards set based on organoleptic, physical properties, pH, density, and viscosity. This research discusses the antibacterial activity of liquid soap. Formula 1 showed better antibacterial activity than formulas 2 and 3, with an inhibitory area reaching 23.84 mm. This can be explained by the fact that Formula 1 has a smaller particle size, namely 2161 nm. Formula 1 has the lowest AgNO3 concentration. The higher the concentration of AgNO3 used in the synthesis, the greater the amount of Ag+ that must be reduced, resulting in greater agglomeration and a larger size distribution of Ag nanoparticles.

Abstract

This study aims to evaluate the effect of solvent types on the total phenolic content and antioxidant activity of turi leaf extract (Sesbania grandiflora). The types of solvents used include ethanol, ethyl acetate, and n-hexane. The total phenolic content was measured using the Folin-Ciocalteu method with gallic acid as a standard, while the antioxidant activity was determined using the DPPH quenching method. The results showed that the highest total phenol content was obtained from ethyl acetate solvent (12.31 µg/mL), followed by ethanol (9 µg/mL) and n-hexane (6.34 µg/mL). However, antioxidant activity based on IC50 showed different results, where the extract with n-hexane solvent had the highest antioxidant activity (IC50 = 142.9 µg/mL) compared to ethyl acetate (IC50 = 245.47 µg/mL) and ethanol (IC50 = 271.8 µg/mL). These differences indicate that the type of solvent affects not only the amount but also the type of phenolic compounds and other bioactive compounds in the extract. This study highlights the importance of selecting an appropriate solvent to enhance the extraction efficiency of phenolic compounds and antioxidant potential.
