The and have a long history of being used traditionally for treatment of various types of disorders. Most of the uses have been without any scientific evidence and toxicological assessment. We evaluated the mutagenic and cytotoxic capabilities of various parts of , and . Ames mutagenicity assay determined the mutagenicity activity against TA 98 and TA 100 bacterial strains of without metabolic activator S9 system. The number of mutant colonies in negative control was considered as limit to determine the mutagenicity effects of every extract. Brine shrimps lethality bioassay was used to determine the cytotoxic capabilities of the selected plants. The and did not showed any mutagenic activity both for frameshift mutation (TA98) and base-pair substitution (TA100) without S9 mixture. The crude methanolic extract of stem showed moderate cytotoxicity (53.33%) at 1000 μg/ml with LD value 599.634 The fruit showed a toxicity of 60% at 1000 μg/ml with LD value 367.730. The (whole plant) showed lethality of 63.3% at 1000 μg/ml, with LD 204.833. The absence of any mutagenic activity of crude extract of the tested plants in both bacteria strains, TA 98 and TA 100 without the S9 mix confirms the safety of these plants to the consumers.
[植物名称1]和[植物名称2]在传统医学中用于治疗各类疾病已有很长历史。其大多数用途都缺乏科学依据和毒理学评估。我们评估了[植物名称1]、[植物名称2]和[植物名称3]不同部位的致突变和细胞毒性能力。艾姆斯氏诱变试验在无代谢激活剂S9系统的情况下,测定了[植物名称1]对TA 98和TA 100细菌菌株的诱变活性。阴性对照中的突变菌落数被视为确定每种提取物诱变作用的界限。采用卤虫致死生物测定法来确定所选植物的细胞毒性能力。在无S9混合物的情况下,[植物名称1]和[植物名称2]对于移码突变(TA98)和碱基对置换(TA100)均未显示任何诱变活性。[植物名称3]茎的粗甲醇提取物在1000μg/ml时显示出中等细胞毒性(53.33%),LD值为599.634;[植物名称4]果实在1000μg/ml时毒性为60%,LD值为367.730;[植物名称5](全株)在1000μg/ml时致死率为63.3%,LD为204.833。在无S9混合物的情况下,受试植物粗提取物对TA 98和TA 100这两种细菌菌株均无任何诱变活性,这证实了这些植物对消费者是安全的。
