Background: Tetrapleura tetrapteraTaubert (Fabaceae) fruits are employed by herbal practitioners in the management of uterine leiomyoma, but its usage in this regard and level of safety in chronic administration has not been sufficiently established. This study evaluated the toxicity effects of T. tetrapteraethanol fruit extract and explored its antileiomyoma effect in female Sprague Dawley (SD) rats. Methods: Sub-chronic toxicity test of the extract was done, with biochemical and hematological changes as well as histopathology of organs assessed. Leiomyoma formation was induced in SD rats with monosodium glutamate (MSG) and the extract given at 100, 200 and 400 mg/kg doses, following both the preventive and curative methods. Total serum cholesterol, protein and estradiol were determined, as well as histopathology assessment of the uterus. Phytochemical profiling of the extract was evaluated by analytical high-performance liquid chromatography (HPLC). Results: No significant alterations were seen in the biochemical and hematological indices in the toxicity test. The vital organs showed no changes at 200 mg/kg, but at 800 mg/kg it appeared to induce multiplication of glandular epithelium and stromal fibrosis in the uterus, and induced perivascular inflammation around the vessels of the heart. Total serum cholesterol and estradiol were significantly elevated (P≤ 0.05) on treating normal female rats with 800 mg/kg MSG. Preventive and curative treatment of MSG-treated animals with the extract significantly decreased the elevated serum cholesterol (P≤ 0.01) and estradiol (P≤ 0.05). Histological studies of the uterus showed an amelioration of the proliferating fibroid cells with administration of the extract, which was more evident in the curative treatment. Result of HPLC analysis of the extract revealed rich composition in bioactive compounds such as umbelliferone, ferulic acid, aridanin, echinocystic acid, naringenin and hentriacontane. Conclusion: The ethanol fruit extract of T. tetrapterais relatively safe in Sprague Dawley rats in low doses and has antifibroid potential as seen in its significant reduction in the elevated total cholesterol and estradiol content as well as its ability to decrease uterine leiomyoma proliferation, which may be due to its array of phytochemical constituents. |
