Plantago asiatica is a member of the Plantaginaceae family, and is widely distributed in East Asia. In our previous work, a single active compound, plantamajoside was isolated and confirmed to have glycation inhibitory activity, and did not possess toxicity during a 90 day repeated oral toxicity test in rats. In the present study, a chromosomal aberration test was performed to investigate the genotoxicity of plantamajoside. From the results of the cytotoxicity test, plantamajoside proved to be less toxic when it was treated combined with S9 cell fractions. However, there was a significant increase in structural aberrations during the short-term treatment of plantamajoside at its highest dose (5000 microg/mL) even when combined with S9. This seems to have been a natural phenomenon due to the very high dose of plantamajoside that was used. However, to confirm the safety of plantamajoside for its potential use as a phytochemical agent in health products, additional mutagenicity tests are necessary.
车前草是车前科的一员,广泛分布于东亚。在我们之前的工作中,分离得到了一种单一的活性化合物车前草苷,并证实其具有糖基化抑制活性,且在大鼠 90 天重复口服毒性试验中没有毒性。在本研究中,进行了染色体畸变试验以研究车前草苷的遗传毒性。从细胞毒性试验的结果来看,当与 S9 细胞部分一起处理时,车前草苷的毒性较小。然而,在最高剂量(5000μg/mL)的短期处理下,即使与 S9 一起处理,结构畸变也显著增加。这似乎是由于使用了非常高剂量的车前草苷,是一种自然现象。然而,为了确认车前草苷作为保健品中植物化学物质的潜在用途的安全性,需要进行额外的致突变性试验。
