Abstract

Free radicals are reactive oxygen compounds that are known to be compounds that have free or unpaired electrons. Free radicals will look for new partners so that they will easily bind to other substances such as proteins, fats, and DNA in the body, resulting in cell damage and causing various degenerative diseases. To overcome the negative effects of free radicals, a substance that acts as an antioxidant is needed. Sonneratia Ovata or often called pedada by coastal communities is often used to treat various diseases including diabetes, ulcers, analgesic diarrhea, inflammation, pain and accelerate wound healing. This study aims to examine the levels of flavonoid compounds in the ethanol extract of S. ovata leaves using the colorimetric method and antioxidant activity using the ABTS method (2,2 azinobis (3-ethylbenzothiazolin-6- sulfonic acid) and DPPH (2,2-diphenyl-1-picrylhydrazyl) on the ethanol extract of S. ovata leaves. The research process began with the extraction of S. ovata leaves with 96% ethanol, followed by determination of total flavonoid levels and antioxidant testing. From the results of the determination of total flavonoid levels, it was found that the ethanol extract of S. ovata leaves had a flavonoid content of 38,248 ± 0.142 mgQE/gram. In measuring antioxidant activity using the DPPH and ABTS methods, the IC50 values were 31.785 ± 0.047 ppm and 28.303 ± 0.558 ppm, respectively. Based on these results, the ethanol extract of S. ovata provided very strong antioxidant activity with an IC50 value of less than 50 ppm.

Abstract

Background: The search for natural antioxidants as alternatives to synthetic ones is crucial due to safety concerns. Nipa palm (Nypa fruticans Wurmb) leaf, an abundant mangrove waste product in Indonesia, is a potential source of natural antioxidants but remains understudied, particularly regarding its reducing power capacity. Objective: This study aimed to evaluate the antioxidant activity of nipa palm leaf ethanol extract through two mechanisms: free radical scavenging activity (DPPH method) and ferric reducing antioxidant power (FRAP method).Methods: Dried nipa leaf powder was macerated with 70% ethanol. The antioxidant activity was determined by the DPPH method to obtain the IC?? value and by the FRAP method to measure the reducing power expressed as µM Fe(II) equivalent per gram of extract. Vitamin C and Quercetin were used as standards for the DPPH and FRAP assays, respectively.Results: The extraction yield was 15%. The nipa leaf extract exhibited very strong antioxidant activity with an IC?? value of 42.08 µg/mL in the DPPH assay. Furthermore, the FRAP assay confirmed its potent reducing capacity, with a value of 2850.50 µM Fe(II)/g extract.Conclusion: The ethanol extract of nipa palm leaves demonstrates potent antioxidant activity through both free radical scavenging and reducing power mechanisms. These findings suggest that nipa leaf, currently an underutilized waste product, is a promising source of natural antioxidants for potential applications in the food, cosmetic, and pharmaceutical industries.

Abstract

Ficus benjamina L. (weeping fig) has been traditionally used in folk medicine, but its antioxidant potential remains scientifically underexplored. This study aimed to comprehensively evaluate the in vitro antioxidant activity of a 70% ethanolic extract of F. benjamina leaves using two assays. The extract was prepared by maceration and subjected to phytochemical screening. Antioxidant activity was assessed through the ABTS radical scavenging assay, reported as IC?? and Trolox equivalents (TE), and the FRAP reducing power assay, reported as FeSO? equivalents (FE). Phytochemical analysis revealed abundant flavonoids, phenolics, and tannins. The extract demonstrated potent antioxidant activity, with an IC?? of 28.4 ?g/mL in the ABTS assay and a value of 412.3 mg TE/g. The FRAP assay confirmed strong reducing power, with a value of 1850.6 ?mol FE/g. A very strong positive correlation (r = 0.978) was found between the results of the two assays. While less potent than pure ascorbic acid, the extract's activity is significant for a plant extract. The 70% ethanolic extract of F. benjamina leaves possesses substantial in vitro antioxidant activity, attributed to its high phenolic and flavonoid content. The strong correlation between ABTS and FRAP results indicates complementary antioxidant mechanisms.

Abstract

Hyperuresemia is a metabolite syndrome characterised by high levels of uric acid in the blood. Hyperuresmia in advanced stages can cause gout or pyrexia (a disease that affects the joints and causes joint damage), kidney stones, kidney damage, and hypertension. The nipah plant (Nypa fruticans. Wurmb) is traditionally used in the treatment of stomach pain, diabetes, fever, toothache, uric acid reduction and headache medicine. In general, the content of secondary metabolite compounds from nipah plants includes flavonoids, phenols, tannins, terpenois, steroids, alkaloids and saponins. The purpose of this study was to determine the xanthine oxidase inhibitory activity of ethanol extracts and fractions of nipah leaves (Nypa fruticans. Wurmb). Extraction process using maceration method with 96% ethanol solvent, fractionation using liquid-liquid partition method with separating funnel. . Testing the inhibition of xanthine oxidase enzyme activity in vitro using UV/VIS spectrophotometer. The results showed that ethanol extract, water fraction, ethyl acetate fraction and n-hexane fraction showed inhibitory activity of xanthine oxidase enzyme with IC50 values of 47.558 ± 2.862; 18.755 ± 3.821; 3.543 ± 1.440 and 110.213 ± 1.577 ppm, respectively. From the results of the study it can be concluded that ethanol extracts and fractions of nipah leaf fronds (Nypa fruticans.Wurmb) can inhibit the activity of xanthine oxidase enzyme with ethyl acetate fraction giving the highest inhibitory activity with IC50 value of 3,543±1,440 ppm.
