Abstract

Soursop leaves (Annona squamosa L.) are known to contain secondary metabolite compounds such as flavonoids, alkaloids, tannins, and polyphenols that have the potential as natural antioxidants. Antioxidants play an important role in warding off free radicals that can cause skin damage, premature aging, and degenerative diseases. This study aims to formulate a lotion preparation with soursop leaf extract and evaluate its antioxidant activity using the ABTS (2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)) method. The extract was obtained through a maceration method using 96% ethanol. The lotion formula was prepared with various concentrations of soursop leaf extract, then tested for physical quality properties, as well as antioxidant activity by measuring the IC50 value of the ABTS radical solution. The results showed that soursop leaf extract has very strong antioxidant activity, indicated by a strong IC50 value. The resulting lotion preparation has good physical characteristics and antioxidant activity comparable to the comparator quercetin. Thus, soursop leaf extract lotion has the potential to be developed as a natural skin care product with moisturizing and antioxidant functions

Abstract

Rambai leaf (Baccaurea motleyana Müll. Arg.) is traditionally used to treat smallpox, diarrhea, and bruises, but it has the potential to be contaminated with heavy metals such as lead (Pb) and cadmium (Cd) which are toxic and accumulative. This study aims to determine the levels of Pb and Cd in rambai leaf and compare them with the safe limits of BPOM RI and WHO. The type of research is descriptive quantitative with Atomic Absorption Spectrophotometry (AAS) method using an air-acetylene flame system. The study population was all rambai plants in Nanga Kantuk Village, West Kalimantan, with purposive sampling. The main instrument was SSA contrAA 800, while data analysis was carried out through a linear calibration curve (R> 0.998), regression, and calculation of levels (mg/kg). The results showed Pb levels of 4.29 mg/kg and Cd <LOD (0.0131 mg/L). These results indicate that Pb metal was detected, while Cd was not detected quantitatively. In conclusion, the levels of Pb and Cd in rambai leaf simplicia are still below the safe limits of BPOM RI (Pb ≤ 10 mg/kg; Cd ≤ 0.3 mg/kg), so it is safe to use as a traditional medicine ingredient from the aspect of heavy metal contamination.

Abstract

Hypertension is a global health problem with high prevalence and is a major risk factor for cardiovascular disease. One of the main mechanisms of hypertension is increased Angiotensin Converting Enzyme (ACE) activity. The use of synthetic ACE inhibitors often causes side effects, such as nausea, hyperkalaemia, headaches, swelling of the lower skin, coughing, taste disturbances, and angioneurotic edema. Therefore, natural-based alternatives are needed. Lime leaves (Citrus amblycarpa) are known to contain various bioactive compounds that have the potential to act as ACE inhibitors. This study aims to analyze the interaction of active compounds in lime leaves with ACE through molecular docking, as well as to predict their ADME profile and toxicity. The study was conducted in silico using PyRx–AutoDock Vina for molecular docking, PyMOL and BIOVIA Discovery Studio for interaction visualization, SwissADME for ADME prediction, and ToxTree for toxicity analysis. Method validation was performed based on an RMSD value < 2Å. The results of the study indicate that 1,3-benzenedicarboxamide is the best compound with an RMSD value of 1.998 Å and a bond free energy (ΔG) of −6.4 kcal/mol, forming specific amino acid residue bonds similar to the native captopril ligand. ADME predictions meet Lipinski's Rule of Five criteria and fall into the low toxicity category (Class I) based on Cramer's rules. The compound 1,3-benzenedicarboxamide has the potential to be developed as a candidate ACE inhibitor for hypertension therapy.

Abstract

Dental caries remains a major oral health problem globally and in Indonesia, triggered by Streptococcus mutans biofilm. Chemical agents such as chlorhexidine have side effects, encouraging the use of natural alternatives from Moringa oleifera L. leaves. This study aims to evaluate the antibacterial activity of ethanol extracts and n-hexane, ethyl acetate, and water fractions against Streptococcus mutans ATCC 25175, identify the most active fraction, and determine the MIC and MBC. This quantitative study used diffusion and dilution methods. Bacteria: Streptococcus mutans ATCC 25175; samples: ethanol extract of Moringa oleifera L. leaves and n-Hexane, ethyl acetate, and water fractions. Data analysis used SPSS 25 One-Way ANOVA, Tukey (p<0.05). Results showed that the ethyl acetate fraction was the most active with 12.36 mm inhibition at 45%; MIC and MBC were 30% ANOVA significant (p=0.000). The ethyl acetate fraction has strong caries prevention potential, supporting herbal development.

Abstract

Indonesia has reached 20.4 million adults with the fifth highest number of diabetes in the world and is estimated to be 28.6 million by 2050. The use of acarbose has side effects such as digestive problems to potential for the liver and kidneys, so these problems can be overcome with herbal plant treatment, one of which is the active compound of neem leaves (Azadirachta indica). This study aims to analyze the interaction of 20 neem leaf compounds with α-amylase enzymes through the molecular docking approach, ADMET prediction, and modification of potential new compounds as antidiabetic candidates. This research was conducted in silico using PyRx-AutoDock Vina for docking, VegaZZ, PyMOL, and Discovery Studio for optimization and visualization, SwissADME for ADME prediction, and Toxtree for toxicity test. The docking method validation is expressed in RMSD values of <2 Å. The docking results showed that Kaempferol had a ΔGBinding of -7.9 kcal/mol, an RMSD value of 1.229 Å and had a similarity of amino acid residues to the native ligands ASP:197. Kaempferol has a good ADME profile, High (III) category toxicity and is mutagenic and carcinogen. The design of the new compound of Kaempferol i.e. 2-(4-hydroxycyclohexyl)-1-methoxybutane-1,4-diol has amino acid residue similarity to the native ligands ASP A:197, ΔGBinding -5.6, RMSD value 1,704 Å and has good ADME, Low (I) category toxicity. The active compound of neem leaves has the potential to be an inhibitor of the enzyme α-Amylase.
