Effects of Cadmium Stress on Seedlings Growth and Active Ingredients in Salvia miltiorrhiza

  • 摘要: 采用盆栽试验方法,研究了镉(Cd2+)对丹参(Salvia miltiorrhiza Bunge)的生长及其有效成分积累的影响。结果表明,镉胁迫下丹参的生长受到了显著抑制,体内Cd2+残留量、可溶性蛋白含量和膜脂过氧化程度显著增加,叶绿素含量降低。与对照相比,镉胁迫下丹参叶片水溶性酚酸类化合物咖啡酸和迷迭香酸的含量显著降低(p<0.05),原儿茶酸含量增加,丹参素、原儿茶醛和丹酚酸B的含量也降低,但变化均不显著 (p> 0.05)。而根系中这6种酚酸类化合物含量均降低,其中迷迭香酸的含量变化极显著(p<0.01)。镉胁迫下丹参根系脂溶性丹参酮类化合物二氢丹参酮、丹参酮Ⅰ和隐丹参酮含量均显著降低,而丹参酮ⅡA含量变化不显著。丹参叶片中水溶性酚酸类化合物合成关键酶苯丙氨酸解氨酶(PAL)和酪氨酸氨基转移酶(TAT)的活性显著降低,而肉桂酸4-羟化酶(C4H)和4-香豆酸CoA连接酶(4CL)的活性显著升高。这些结果均说明镉胁迫可以降低丹参的产量和质量。
    Abstract: Effects of cadmium stress on seedlings growth and active ingredients in Salvia miltiorrhiza were investigated. Results showed that cadmium stress inhibited seedlings growth and increased Cd2+ accumulation in both soil and seedlings. Moreover,both soluble protein content and membrane lipid peroxidation degree increased,while photosynthetic pigments content decreased under stress conditions. Compared with the control,in stressed S. miltiorrhiza leaves,the accumulation of six phenolic acid compounds showed different variant characteristics. Both caffeic acid and rosmarinic acid accumulation decreased significantly (p<0.05),while the content of protocatechuic acid increased (p>0.05),and the levels of tanshinol,protocatechuic aldehyde and salvianolic acid B decreased (p>0.05). However,the accumulations of the phenolic acids components and four tanshinone ingredients all decreased in stressed roots,and the variances of rosmarinic acid,dihydrotanshinone,tanshinone Ⅰ and cryptotanshinone were significant (p<0.05). Moreover,in the leaves of the stressed plant,the activities of PAL and TAT decreased significantly,but C4H and 4CL content increased significantly. These results showed that cadmium stress could reduce the production and quality of S. miltiorrhiza.
