Abstract

Lecaniodiscus cupanioides Planch (ex. Benth) is effective in treating burns, fevers, and inflammatory conditions. This study investigates the toxicity effects of the aqueous leaf extract (ALE) of L. cupanioides and its effect on stress-induced ulcers in animal models. The plant was collected and a 1:30 (g/ml) plant powder/solvent ratio was extracted using an ultrasonic bath at 50 °C for 45 min. Up-and-down procedure was used for acute toxicity. During subacute toxicity testing, a total of 20 mice were divided into four groups of five animals each. While group 1 served as control, groups 2, 3, and 4 received 250, 500, and 1000 mg/kg of the extract daily for 21 days. On day 22nd, animals were sacrificed and samples were collected for hematology, biochemical, and histological analyses. In the stress-induced ulcer activity, male albino mice were randomly separated into 5 groups of 5 animals, treated with the test drug, and then dissected after being stressed using the water immersion model. LD50 was > 5000 mg/kg, and in biochemical examination, there was a significant decrease in the ALP level at medium and high doses (p value < 0.05) and non-significant alterations in the values of urea, creatinine, alanine aminotransferase (ALT), aspartate aminotransferase (AST), body weight and hematology parameters (p > 0.05). The histology results showed no evidence of liver and kidney toxicity. In conclusion, aqueous leaf extract of L. cupanioides was safe following a single dose (at 5000 mg/kg) and following repeated doses for 21 days (at 250, 500, and 1000 mg/kg). This study demonstrated that the extract had a significant effect on stress-induced ulcers at various dose levels when compared to the control (native, negative control, and omeprazole). The animals treated with 200mg/kg and 400mg/kg of the extract showed a significant increase in ulcer score, ulcer index, ulcer severity, and total acidity (p < 0.05). The ulcer protection ability of the aqueous plant extract was dose-dependent.
