Near-critical extraction of major alkaloids from poppy straw was performed successfully with a simple device consisting mainly of two chromatographic pumps and a pressure regulator. The optimum extractant, consisting of carbon dioxide, methanol and water, gave a quantitative extraction of thebaine, codeine and morphine in 20 min. The method was compared with a classical liquid-solid extraction procedure and carbon dioxide was shown to act as a transporting agent of the extraction solvent (methanol-water) into the vegetable matrix.
使用一种主要由两台色谱泵和一个压力调节器组成的简单装置，成功地从罂粟秸秆中近临界萃取了主要生物碱。由二氧化碳、甲醇和水组成的最佳萃取剂在20分钟内定量萃取了蒂巴因、可待因和吗啡。将该方法与经典的液固萃取方法进行了比较，结果表明二氧化碳可作为萃取溶剂（甲醇 - 水）进入植物基质的传输剂。
