In this research antidiabetic, analgesic and antiulcer potential of traditional ethnomedicinal plant: Emex spinosa (L.) Campd. (Family Polygonaceae) was evaluated by extracting its phytoconstituents using methanol (MeOH) solvent through maceration protocol. The quantitative phytochemical analysis of the extract revealed flavonoids were highest in leaf extract (15.63±0.93 mg/mL) and with (11.5±0.57 mg/mL) in stem. Alkaloids and tanins were also present in the samples in various conc. while saponins were absent. To confirm pharmaceutical potential of plant against ulcer, diabetes and analgesic infirmities, a model experimental animal wistar albino rats (Rattus norvegicus) were used. In antiulcer study, using hot plate method the maximum results were observed with 250 mg/kg in the 2.5 hours of study. The leaf extract showed a 40.41±2.73 latency time and the fruit with a 36.77±2.41, and the stem with a 27.85±3.09, which was comparable to the standard drug Aspirin, i.e., 47.5±0.57. For analysis of antiulcer potential of the plants parts doses of 250 and 500 mg/kg was applied to check the reclamation of ethanol-induced acute ulcer and of Aspirin-induced chronic ulcer of stomach. In order to confirm efficacy of the drug potential of plant following parameters like microscopic evaluation, gastric volume, total acidity, mucosa weight, ulcer index, pH and histopathology of stomach were analyzed. In antidiabetic analysis, in an acute study after a single dose of 500 mg/kg extract after 2hrs the blood glucose levels were 367±51.09958NS, 416±59.79548NS, 437.5±61.96437NS mg/dL for leaf, stem and fruit, respectively. After4hrs 351.75±88.27644NS mg/dl, 448.25±25.64948NS mg/dl, 445.25±27.07205NS mg/dl and after 6hrs 354.5±92.70428NS, 442±24.60691NS, a440±33.16625NS mg/dl, respectively. The analgesic activity was explored by applying hot plate, tail flick and formalin paw licking method. In hot plate method the maximum results were observed with 250mg/kg in the 2.5 hours of study. The leaf extract showed a 40.41±2.73 latency time and the fruit with a 36.77±2.41 and the stem with a 27.85±3.09, which was comparable to the standard drug Aspirin, i.e., 47.5±0.57. The respective plant extracts at 250mg/kg showed a gradual rise in latency time when compared to the control. It was concluded that all three components of E. spinosa perform proved to be significant as potential source of herbal medicines to cure different prevalently occurring diseases. Furthermore, it was confirmed through results analysis that plant t can be used to discover novel drug using dedicated high throughput techniques and ethnopharmacological approaches.
