Abstract

Euphorbia milii is a common garden plant and its leaves have antibacterial activity, due to the presence of saponins, flavonoids, and tannins. As there is an increasing antibiotic resistance to Staphylococcus aureus, there is potential for E. milii as a new antibacterial candidate. The purpose of this study was to determine secondary metabolites of saponins, flavonoids, tannins and to determine the antibacterial activity of E. milii leaves in inhibiting the growth of Staphylococcus aureus (in vitro). Simplisia was extracted by sonication method, then fractionated with a separatory funnel. Extracts and fractions were analyzed qualitatively by tube test and thin layer chromatograpy (TLC). The antibacterial activity of methanol extract (320; 160; and 80 mg/ml) and n-butanol fraction (32; 16; and 8 mg/ml) was tested by disc diffusion method. The results of qualitative test showed that the extracts and fractions were positive for saponins, flavonoids, and tannins.  In antibacterial test, extract at a concentration of 320 mg/ml was able to inhibit bacterial growth with moderate activity category (6.5 mm). Extracts at 160 mg/ml and 80 mg/ml, as well as n-butanol fractions at all concentration showed weak antibacterial activity (<5 mm). Theseresult suggest that the extracts and fractions positively contain metabolites of saponins, flavonoids, and tannins. The extracts and fractions were able to inhibit the growth of staphylococcus aureus, but the activity was not greater than the positive control.

Abstract

The repeated use of cooking oil more than twice is still common in Indonesian society. However, used cooking oil can negatively affect health, being even more detrimental than saturated fatty acids. Additionally, it contributes to pollution in soil and water. One effective method for repurposing used cooking oil is by converting it into soap. This community service initiative aims to promote the utilization of used cooking oil in economically valuable products while reducing the amount of waste oil that is discarded into the environment. The training was conducted for PKK cadres in Bengkaung Village and facilitated by pharmacists, dermatologists, and students from the Faculty of Medicine and Health Sciences at the University of Mataram. The soap-making process begins by adding charcoal to the used cooking oil for 72 hours. This step helps remove hazardous substances and unpleasant odors. Afterward, the oil is filtered and combined with essential soap-making ingredients, including sunflower oil, virgin coconut oil (VCO), olive oil, sodium hydroxide (NaOH), and water. NaOH is critical for the saponification process, which transforms the oil into soap. To enhance the aesthetic value and benefits of the soap, ingredients like honey, yogurt, or natural dyes such as butterfly pea flowers can be incorporated. The mixture is then poured into molds and allowed to harden. Given the simple process and the ease of obtaining the necessary tools and materials, the PKK cadres in Bengkaung Village have shown enthusiasm for making soap from used cooking oil. This activity is expected to broaden their knowledge and provide business opportunities to help increase family income in the village.

Abstract

Garlic is a herbal plant that is widely used as a medicinal ingredient, because it contains secondary metabolite compounds such as alkaloids, flavonoids, tannins, phenols, terpenoids and saponins. The secondary metabolite content of plants is influenced by genetic, ontogenic, morphogenetic and environmental factors that can influence the biosynthesis and accumulation of secondary metabolites. Garlic is generally only used for the bulbs, while other parts such as the leaves and skin are still not widely used. This study aims to identify the secondary metabolite profile of ethanol extract of garlic leaves, bulbs and peels using the gas chromatography mass spectrometry (GC-MS) method. Identification of secondary metabolite compounds contained in each 70% ethanol extract was analyzed using the tube test, thin layer chromatography (TLC) and GC-MS methods. The results of analysis of secondary metabolite content using the tube test and TLC method showed that the ethanol extract of garlic leaves, skin and bulbs positively contained flavonoids, tannins, phenols and saponins. The results of secondary metabolite profile analysis using the GC-MS method from the ethanol extract of garlic skin and bulbs showed that 5 compounds were obtained with the main compound being 3,4-Dihydroxyphenylacetic acid and 23 compounds with the main compound being 1,2-Benzenedicaboxylic acid and palmitic acid, while the leek extract white only detected 1 compound. The conclusion is that the ethanol extract of garlic leaves, skin and bulbs has secondary metabolites in the form of flavonoids, tannins, phenols and saponins. There are differences in the profile of secondary metabolite compounds in the ethanol extract of garlic leaves, skin and bulbs in terms of the results of GC-MS analysis.
