Comprehensive chemo-profiling of coumarins enriched extract derived from Aegle marmelos (L.) Correa fruit pulp, as an anti-diabetic and anti-inflammatory agent

Abstract

Aegle marmelos (L.) Correa is an Indian medicinal plant known for its vast therapeutic activities. In Ayurveda, the plant is known to balance “vata,” “pitta,” and “kapha” dosh. Recent studies suggest anti-inflammatory, anti-microbial, and anti-diabetic potential butlack in defining the dosage over thetherapeutic activities. This study aims to determine the chemical profile ofAegle marmelosfruit extract; identification, enrichment, and characterization of the principal active component(s) having anti-inflammatory and anti-diabetic potential.Targeted enrichment of total coumarins, focusing on marmelosin, marmesin, aegeline, psoralen, scopoletin, and umbelliferone, was done fromAegle marmelosfruit pulp, and characterized using advanced high-throughput techniques. In vitro and in silico anti-diabetic and anti-inflammatory activities were assessed to confirm their efficacy and affinity as anti-diabetic and anti-inflammatory agents. The target compounds were also analysed for toxicity by in silico ADMET study and in vitro MTT assay on THP-1 and A549 cell lines. Thecoumarins enrichment process designed, was found specific for coumarins isolation as it resulted into 48.61% of total coumarins enrichment, which includes 31.2% marmelosin, 8.9% marmesin, 4% psoralen, 2% scopoletin, 1.7% umbelliferone, and 0.72% aegeline. The quantification with HPTLC and qNMR was found to be correlated with the HPLC assay results. The present study validates the potential use ofAegle marmelosas an anti-inflammatory and anti-diabetic agent. Coumarins enriched from the plant fruit have good therapeutic activity and can be used for Phytopharmaceutical ingredient development. The study is novel, in which coumarins were enriched and characterized by a simple and sophisticated methodology.
