Abstract Toxic metals can cause toxicity problems in the organisms exposed to them. Many substances are able to reverse this toxicity. Among the secondary metabolites of plant origin investigated are flavonoids. To evaluate the cytoprotective activity, dry mass and possible damage to the membranes of Lactuca sativa (lettuce) seedlings subjected to different concentrations of mercury chloride in association with rutin in suballelopathic concentration (8 μg/mL) were determined. It was observed that rutin gives cytoprotection to lettuce seedlings, allowing greater growth and development of the roots of these seedlings, probably through the coordination of mercury with the rutin molecule. The interaction of rutin with mercury chloride was evidenced through vibrational spectroscopy (Raman and FTIR). Although mercury chloride causes cytotoxicity in several plant species, its complex with rutin can mitigate these effects.

芦丁降低氯化汞的植物毒性作用并通过振动光谱法（拉曼和 FTIR）评估相互作用

摘要 有毒金属会导致接触它们的生物体出现毒性问题。许多物质能够逆转这种毒性。在研究的植物来源的次生代谢物中有类黄酮。为了评估细胞保护活性，测定了在不同浓度氯化汞与亚化感浓度 (8 μg/mL) 芦丁的作用下，莴苣（莴苣）幼苗的干重和可能对细胞膜造成的损害。据观察，芦丁对莴苣幼苗提供细胞保护，使这些幼苗的根部有更大的生长和发育，这可能是通过汞与芦丁分子的协调实现的。芦丁与氯化汞的相互作用通过振动光谱（拉曼和 FTIR）得到证实。
