Abstract

Research on qualitative test of secondary metabolites compounds and test of lowering cholesterol activity has been done on bidara leaves (ziziphus mauritiana) with methanol extract by maceration methods. The aim of this research was to determine cholesterol-lowering activity of methanol extract on bidara leaves (ziziphus mauritiana). The procedure used was in this study consisted of extraction, phytochemicals screening such as alkaloids, tannins, triterpenoids, flavonoids and saponins, and test of cholesterol lowering activity using UV-Vis spectrophotometry at a wavelength of 423 nm. Based on research results, determine cholesterol lowering activity of methanol extract on bidara leaves (ziziphus mauritiana) has proven to reduce cholesterol levels by 80.4598% because of bidara leaves contains of active secondary metabolites such as triterpenoids, tannins and flavanoids.

Abstract

Electroplating process has a negative effect in form metal ions waste. Today, industrial wastewater treatment widely using aluminum sulfate or alum as synthetic coagulants, although hazardous and expensive. This study was conducted to discover the activity of Moringa seeds (Moringa oleifera) as natural coagulants to substitute synthetic coagulants. Trapped metal ions detected by ICP-OES. The results showed that moringa seed coagulants could reduce 53% Cr, 64.56% Mn, and 92.89% Pb in the addition of 15 grams of moringa seed coagulants.

Abstract

The kitolod plant (Hippobroma longiflora) has been demonstrated to possess antibacterial activity against Streptococcus mutans, the bacterium responsible for the development of dental caries. The objective of this study was to formulate a mouthwash preparation using kitolod leaf extract. The extract was formulated into three distinct formulations. The mouthwash was evaluated for its pH, viscosity, stability, and antibacterial activity. The antibacterial evaluation was executed in accordance with the Kirby-Bauer method. The positive control utilized in this study was 0.2% chlorhexidine. The pH test results indicated that all three formulations had a pH of 6. The viscosity test demonstrated that all formulations had a viscosity of 0.99, which is close to that of water. The antibacterial evaluation against S. mutans indicated that formulation 2 demonstrated the most pronounced antibacterial activity, exhibiting an inhibition zone measuring 3.81 mm. All three formulations exhibited stability at ambient temperature. In light of the findings from this study, it can be posited that formulation 2 possesses the potential to serve as a natural mouthwash.
