Abstract
Medicinal plants have been extensively exploited for their immense pharmacological and immune-supporting potential. Fruit of Citrullus colocynthis has several active secondary metabolites such as phenolics, flavonoids, and essential oils that are used in traditional medicines as antidiabetic, anti-inflammatory, antioxidant, and antimicrobial agents. In this study, phytoconstituents in organic fractions (n-hexane, chloroform, and ethyl acetate) of the methanolic extract of C. colocynthis were analyzed and identified by FT-IR, HPLC, and GC-MS analysis. Ethyl acetate fraction showed the highest antioxidant scavenging (76 ± .769%) and anti-inflammatory (40 ± .473%) activities at the concentration of 3 mg/mL. Similarly, antidiabetic effect was measured by inhibition of α-amylase where, ethyl acetate fraction (77 ± .844%) exhibited the highest antidiabetic activity. Among all organic fractions, ethyl acetate exhibited strong antimicrobial potential followed by n-hexane and chloroform fractions against selected pathogenic bacteria. Various concentrations of the ethyl acetate extract were tested in-vivo for cytotoxicity and results indicated minor morphological changes in liver cells including ballooning, fatty droplets, and slight accumulation of extracellular matrix even at concentrations of 400 mg/kg. In-silico study showed that stigmasta-7,16-dien-3-ol had a strong interaction with COX-1 and COX-2 to reduce inflammation. The abovementioned results indicate the pharmacological strengths of C. colocynthis to fight several diseases.
