Abstract

Hypercholesterolemia is one of the main factors that increase the risk of heart and blood vessel disease, which can cause atherosclerosis and disorders in fat metabolism. Single garlic is known to contain bioactive compounds such as flavonoids that play a role in reducing cholesterol. This study aims to assess the total flavonoids and anticholesterol activity in vitro of ethanol extract of single garlic (Allium sativum L.). The extraction process was carried out using the maceration method with 96% ethanol as the solvent. Total flavonoids were measured using UV-Vis spectrophotometry with quercetin as the standard, while anticholesterol activity was tested using the Lieberman-Burchard method in vitro. The findings of this study indicate that the sample extract contains secondary metabolites such as flavonoids, alkaloids, saponins, and tannins. Single garlic shows effective flavonoid content in lowering lipid levels. The anticholesterol test shows that this extract can reduce cholesterol levels with a significant IC₅₀ value. The conclusion of this study is that single garlic has the potential as an alternative way to lower cholesterol.

Abstract

Turmeric's leaves possess the greatest antioxidant potential. Therefore, further utilization of flavonoid and phenolic compounds is necessary as antioxidants and to enhance their bioactivity as a medicine. This study aimed to determine the effect of ethanol concentration on total phenolic content using the Folin-Ciocalteau analysis method while total flavonoid content using the AlCl₃ analysis method and antioxidant activity of turmeric leaves using the ABTS method, The research design used was experimental research. The results obtained were ethanol concentrations of 50%, 70% and 96%, The results showed that 70% ethanol extract had the highest phenolic content with an average of (63.77 ± 0.40 mg GAE / g), and 70% ethanol extract had the highest flavonoid content with an average of (22.88 ± 0.5 mg QE / g). However, the strongest antioxidant activity was shown by 96% ethanol extract with an IC₅₀ value of (46.36 ± 1.15 ppm (<50 ppm). Thus, turmeric leaf extract with 96% ethanol solvent had the strongest antioxidant activity, while 70% ethanol produced the highest phenolic and flavonoid levels.
