工業用氟代甲烷類中微量水分的測定卡爾.費休法To assess the medicinal value of cultural anisodus tanguticus, the contents of four bioactive tropane alkaloids, anisodine, anisodamine, scopolamine and atropine, in cultural and wild materials were determined by the hplc method. the results showed that content of each alkaloid in the aboveground parts of cultural and wild samples was lower than that in roots, and this explained why it was not the whole plant but the root that was used as medicinal materials. the content of each alkaloid in the roots of one - year cultural material was lower than that in the two - year plants. the discrepancy of the total of four alkaloids between one - year and wild plants is not significant. moreover, the total of four alkaloids, and the contents of anisodine, scopolamine, and atropine in two - year plants were higher than those in wild plant. thus there is medicinal value in the cultivated a. tanguticus as well as wild a. tanguticus, especially in the two - year cultural a. tanguticus
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 surface modification with silicon coupling reagent to ultrafine silicon dioxide, which roots in waste production in fiber manufacturing, was investigated in this paper
