There is a renewed global interest in plant-based medicine in the last few decades as a result of affordability and efficacy of the form of medicine. However, the safety of many medicinal plants and plant preparations has not been determined. To this end, this study determined the safety of the methanol extracts of the leaves of Guiera senegalensis, Cassia occidentalis, and Ziziphus mauritiana, which are plants commonly used in plant medicine in Africa. Phytochemistry of the plants’ extracts showed alkaloids were the most abundant phytochemical in the extracts, followed by tannins, saponins, flavonoids, and glycosides, respectively. All the rats behaved normally at doses up to 2000 mg kg−1, while at 3000 mg kg−1, rats in C. occidentalis group developed breathing problems. At 5000 mg kg−1, C. occidentalis group showed convulsion, whereas Z. mauritiana and G. senegalensis rats displayed temporary weakness. After 60-day dosing, significant differences (p < 0.05) were observed in the liver enzymes (ALP, AST, ALT, TP, and ALB) of most of the test rats compared with the control. Kidney function test showed the Na+, K+, Cl−, urea, and creatinine of the test rats were reduced compared with the control, but only significant (p < 0.05) in a few of the parameters. Fatty metamorphosis, lymphocytic infiltration, and karyorrhexis were observed in the liver tissues of the treated rats, but not in the control. These results show the plants are nontoxic at moderate doses, but could be injurious at high doses or if taken repeatedly for an extended period.

Guiera senegalensis (JF Gme)、Cassia occidentalis (Linn) 和 Ziziphus mauritiana (Lam) 叶子的毒理学评价

在过去的几十年里,由于药物形式的可负担性和有效性,全球重新对植物性药物产生了兴趣。然而,许多药用植物和植物制剂的安全性尚未确定。为此,本研究确定了 Guera senegalensis、Cassia occidentalis 和 Ziziphus mauritiana 叶子的甲醇提取物的安全性,这些植物是非洲植物药中常用的植物。植物提取物的植物化学表明,生物碱是提取物中含量最高的植物化学物质,其次是单宁、皂苷、黄酮类化合物和苷类。所有大鼠在高达 2000 mg kg-1 的剂量下表现正常,而在 3000 mg kg-1 时,C. occidentalis 组的大鼠出现呼吸问题。在 5000 mg kg-1 时,C. occidentalis 组显示抽搐,而 Z. mauritiana 和 G. senegalensis 大鼠表现出暂时的虚弱。给药 60 天后,与对照相比,大多数测试大鼠的肝酶(ALP、AST、ALT、TP 和 ALB)存在显着差异(p < 0.05)。肾功能测试显示,与对照组相比,测试大鼠的 Na+、K+、Cl-、尿素和肌酐降低,但仅在少数参数中显着(p < 0.05)。在治疗组大鼠的肝组织中观察到脂肪变态、淋巴细胞浸润和核破裂,但在对照组中未观察到。这些结果表明,这些植物在中等剂量下是无毒的,但在高剂量下或长时间重复服用可能会造成伤害。05) 与对照组相比,在大多数试验大鼠的肝酶(ALP、AST、ALT、TP 和 ALB)中观察到。肾功能测试显示,与对照组相比,测试大鼠的 Na+、K+、Cl-、尿素和肌酐降低,但仅在少数参数中显着(p < 0.05)。在治疗组大鼠的肝组织中观察到脂肪变态、淋巴细胞浸润和核破裂,但在对照组中未观察到。这些结果表明,这些植物在中等剂量下是无毒的,但在高剂量下或长时间重复服用可能会造成伤害。05) 与对照组相比,在大多数试验大鼠的肝酶(ALP、AST、ALT、TP 和 ALB)中观察到。肾功能测试显示,与对照组相比,测试大鼠的 Na+、K+、Cl-、尿素和肌酐降低,但仅在少数参数中显着(p < 0.05)。在治疗组大鼠的肝组织中观察到脂肪变态、淋巴细胞浸润和核破裂,但在对照组中未观察到。这些结果表明,这些植物在中等剂量下是无毒的,但在高剂量下或长时间重复服用可能会造成伤害。05) 在一些参数中。在治疗组大鼠的肝组织中观察到脂肪变态、淋巴细胞浸润和核破裂,但在对照组中未观察到。这些结果表明,这些植物在中等剂量下是无毒的,但在高剂量下或长时间重复服用可能会造成伤害。05) 在一些参数中。在治疗组大鼠的肝组织中观察到脂肪变态、淋巴细胞浸润和核破裂,但在对照组中未观察到。这些结果表明,这些植物在中等剂量下是无毒的,但在高剂量下或长时间重复服用可能会造成伤害。
