Deciphering In Vitro and In Vivo Pharmacological Properties of Seed and Fruit Extracts of Flacourtia jangomas (Lour.) Raeusch

The objective of the study was to evaluate the pharmacological properties of the methanolic extract of Flacourtia jangomas (Lour.) Raeusch fruits (PFJM) and seeds (SFJM), along with their soluble fractions in ethyl acetate (fruit: PFJE; seed: SFJE) and chloroform (fruit: PFJC; seed: SFJC). Our phytochemical analysis of the examined extracts confirmed the presence of various therapeutically active phytoconstituents, including flavonoids, tannins, glycosides, and alkaloids. Employing the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical quenching method, SFJC exhibited the highest antioxidative potential, with an IC50 of 48.84, compared to ascorbic acid (IC50 21.77). The thrombolytic activity was assessed through rapid clot analysis of human blood samples, revealing that SFJC demonstrated the highest thrombolytic activity (60.99 ± 2.28%) compared to streptokinase (72.89 ± 2.19%). In the protein denaturation antiarthritic test, the PFJE and SFJC extracts exhibited significant potency, achieving results of 74.28 ± 1.16% and 79.25 ± 0.83%, respectively, at a dose of 500 μg/mL. All samples displayed notable anthelmintic activity by reducing Pheretima posthuma paralysis and death time in a dose-dependent manner compared to albendazole. In both in vivo analgesic tests, SFJC demonstrated substantial (p
