為了評估人工栽培山莨菪的藥用價值,採用高效液相色譜技術對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種托烷類生物堿:樟柳堿、山莨菪堿、東莨菪堿和阿托品的含量進行了測定.結果表明無論是人工栽培還是野生植物,地上部分中4種生物堿含量均遠低於根,這解釋了人們為什麼用山莨菪的根而不是整株入藥.在栽培植物的根中,一年生山莨菪中各生物堿含量均小於二年生山莨菪,其根中4種生物堿總量與野生根相比差異不是很明顯;二年生山莨菪根中, 4種生物堿總量以及樟柳堿、東莨菪堿和阿托品含量均比野生的高.這說明人工栽培的山莨菪,尤其是二年生山莨菪,同野生山莨菪一樣具有一定的藥用價值The composites are soaked in simulated body fluid ( sbf ) to evaluate their biological behaviors. the results suggest that all the composites show bioactive as there are nano apatite / " crystallites formed on the surface of the composites
