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.
