为了评估人工栽培山莨菪的药用价值,采用高效液相色谱技术对人工栽培和野生山莨菪的地上部分和根中具有生物活性的4种托烷类生物碱:樟柳碱、山莨菪碱、东莨菪碱和阿托品的含量进行了测定.结果表明无论是人工栽培还是野生植物,地上部分中4种生物碱含量均远低于根,这解释了人们为什么用山莨菪的根而不是整株入药.在栽培植物的根中,一年生山莨菪中各生物碱含量均小于二年生山莨菪,其根中4种生物碱总量与野生根相比差异不是很明显;二年生山莨菪根中, 4种生物碱总量以及樟柳碱、东莨菪碱和阿托品含量均比野生的高.这说明人工栽培的山莨菪,尤其是二年生山莨菪,同野生山莨菪一样具有一定的药用价值 - In contrast , plants from three populations of e . splendens showed high cu tolerance and substantial cu accumulation , under 100 umol l - 1 the plant of tl / zj / jd can accumulate 143 . 5 , 71 . 9 and 58 . 1 mg kg - 1 cu in the aboveground parts , respectively . the cu concentration in shoots was 16 to 27 times more than cu concentration in roots
