Abstract

Inflammation represents a multifaceted biological reaction that plays a significant role in a variety of chronic pathological conditions and the search for natural anti-inflammatory agents remains a significant focus of pharmacological research. The objective of this study was to assess the in vitro anti-inflammatory properties of an ethanolic extract from the leaf of Carica pubescens (C. pubescens) by examining its effects on cyclooxygenase (COX) enzyme inhibition and conducting protein denaturation assays. An ethanolic extract of the leaf was prepared through maceration using 96% ethanol. Phytochemical screening conducted qualitatively demonstrated that the extract contained flavonoids, alkaloids, saponins, and tannins. Thin Layer Chromatography (TLC) analysis was performed to further identify flavonoids, with quercetin used as the reference standard. The anti-inflammatory activity was assessed using an enzyme immunoassay (EIA) for assessing inhibitory effects on COX-1 and COX-2 and a bovine serum albumin (BSA) denaturation assay. The chromatographic profile of the 96% ethanolic Carica pubescens leaf extract (CPLE 96%) showed a distinct spot with an Rf value comparable to that of quercetin under visible and ultraviolet observation, indicating the presence of quercetin-like flavonoid constituents. The CPLE 96% demonstrated potent, dose-dependent inhibition in both assays. In the protein denaturation assay, the CPLE 96% (100 µg/mL) showed 78.5 ± 2.9 % inhibition, significantly higher than ibuprofen (71.8 ± 2.0 %) and slightly lower than meloxicam (88.4 ± 0.9 %). In the COX inhibition assay, the CPLE 96% exhibited non-selective inhibition with half-maximal inhibitory concentration (IC50) values of 50.42 ± 0.54 µg/mL for COX-1 and 51.18 ± 0.61 µg/mL for COX-2 (Selectivity Index = 0.985 ± 0.017). The findings provide substantial scientific validation for the ethnomedicinal use of C. pubescens, highlighting its dual-acting anti-inflammatory mechanism by inhibiting key inflammatory enzymes and preventing protein denaturation. The extract shows significant potential as a source for developing natural anti-inflammatory therapeutics, warranting further investigation to isolate the active constituents and conduct in vivo studies.

Abstract

Diabetic wounds are a major clinical challenge due to delayed healing and increased complication risks. Ethanol extract of avocado leaves (Persea americana Mill.) has previously shown promise in enhancing tissue regeneration in diabetic wounds, but its potential in gel form remains untested. This study aimed to develop an avocado leaf ethanol extract-based gel and evaluate its woundhealing potential in diabetic mice. Avocado leaves were extracted using 70% ethanol and formulated into a gel, which was evaluated for physical properties and topical suitability. Diabetic mice were divided into five groups: normal control, negative control (gel base), positive control (bioplacenton), and two treatment groups (5% and 10% gel). Diabetes was induced using alloxan (150 mg/kg BW), followed by wound induction and treatment. Wound healing was assessed through visual assessment, wound diameter reduction, and healing duration. Statistical analysis was performed using one-way ANOVA with a 95% confidence level. Results showed the gel meets physical properties (pH test, organoleptic test, homogeneity test, spreadability test) and significantly improved wound healing in diabetic mice. The 5% gel demonstrated wound-healing activity due to bioactive compounds such as saponins, tannins, alkaloids, and flavonoids. Further analysis is needed to identify the specific components responsible for the healing effects, highlighting the gel’s potential for diabetic wound treatment.

Abstract

Introduction: Oxidative stress plays a major role in the pathogenesis of various degenerative diseases, necessitating effective and safe sources of natural antioxidants. The plants kebiul (Caesalpinia bonduc (L.) Roxb.) and bajakah jie xue teng (Spatholobus suberectus Dunn) are known to possess antioxidant potential; however, the activity of their combination has not been extensively reported. Objective: This study aimed to evaluate the antioxidant activity, acute toxicity, and capsule formulation of a combination of 70% ethanol extracts of kebiul seeds and bajakah jie xue teng. Methods: Extraction was performed by maceration using 70% ethanol. Total phenolic content was determined using the Folin–Ciocalteu method, while antioxidant activity was assayed using the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging method. Extract combinations at ratios of 1:1, 1:3, and 3:1 were tested to obtain the lowest IC₅₀ value. An acute toxicity test was conducted on female Swiss mice following the OECD 423 (Acute Toxic Class) guideline at doses of 300 and 2000 mg/kg body weight. The combination with the best antioxidant activity was then formulated into capsules and evaluated for physical quality. Results: The total phenolic content of bajakah jie xue teng extract (47.499 mg GAE/g) was higher than that of kebiul seed extract (16.554 mg GAE/g). The antioxidant activity of kebiul seed extract and bajakah jie xue teng extract showed IC₅₀ values of 125.271 ppm and 86.036 ppm, respectively. The extract combination at a 1:3 ratio exhibited the best antioxidant activity with an IC₅₀ value of 36.434 ppm, which was superior to the 1:1 (78.371 ppm) and 3:1 (52.889 ppm) ratios. The acute toxicity test revealed no signs of toxicity or mortality up to a dose of 2000 mg/kg BW, classifying the combination as Category 5 (unclassified) with an estimated LD₅₀ > 2000 mg/kg BW. The capsule formulation met the physical quality requirements, with granule moisture content of 6.13%, an angle of repose of 24°, weight uniformity within the specified limits, and a disintegration time of 11 minutes and 12 seconds. Conclusion: The combination of kebiul seed and bajakah jie xue teng extracts at a 1:3 ratio demonstrated higher antioxidant activity than the single extracts, exhibited a very low acute toxicity profile, and was successfully formulated into capsules with good physical quality. This combination holds promise for development as an effective and safe natural antioxidant source.

Abstract

Introduction: Excessive free radicals can induce oxidative stress and contribute to the pathogenesis of various degenerative diseases, necessitating the availability of effective antioxidants. Black rice (Oryza sativa L. indica) and mung bean (Vigna radiata L.) are recognized as rich sources of bioactive compounds with prospective antioxidant properties. Objective: This study aimed to analyze the bioactive compound content and antioxidant activity of black rice and mung bean extracts. Methods: Extraction was performed using maceration with 80% ethanol containing 3% citric acid for black rice and 70% ethanol for mung bean. Total anthocyanin and total polyphenol contents were determined in black rice extract, while total polyphenol and total flavonoid contents were analyzed in mung bean extract. Antioxidant activity was evaluated using the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging assay. Results: Black rice extract exhibited total anthocyanin content of 0.802 ± 0.009 mg/g and total polyphenol content of 7.798 ± 0.178 mg GAE/g. Mung bean extract demonstrated total polyphenol content of 15.113 ± 0.396 mg GAE/g and total flavonoid content of 11.052 ± 0.243 mg QE/g. The DPPH assay revealed IC₅₀ values of 3.252 ± 0.269 ppm for vitamin C, 76.692 ± 2.250 ppm for black rice extract, and 102.130 ± 2.268 ppm for mung bean extract. Conclusion: Black rice extract exhibited superior antioxidant activity compared to mung bean extract, as indicated by its lower IC₅₀ value. Both extracts demonstrated moderate to strong antioxidant potential, suggesting their promising application as natural antioxidant sources for functional food development.
