A common-stator macro/micro integrated precision motion one-dimensional linear motor assembly, includes a base, linear guide rails, slide blocks, a U-shaped linear motor stator, a macro motion rotor, a micro motion rotor and a macro/micro integrated platform. A macro and micro motion platforms are connected to form an integrated platform through an elastic member, an outer frame of the macro/micro integrated platform is mounted on the linear guide rails and the slide blocks, the U-shaped linear motor stator is arranged on the base, rotors are respectively mounted on the macro and micro motion platforms, and large-scale overall high-speed motion can be realized when macro and micro rotors are simultaneously driven, and when a motion deviation occurs, the micro motion platform realizes precise displacement output by virtue of elastic deformation due to small inertia and zero friction, and high-frequency motion deviation compensation can be realized by virtue of individual drive.

A method for preparing dehydrocavidine, dehydroapocavidine and their respective composition is provided. The composition is first prepared by isolating and purifying the quaternary ammonium alkaloid components from the medicinal plant 'Yan Huang Lian' (Bunting) through the processes of solvent extraction, water-phase organic extraction, crystallization and recrystallization, and then drying to obtain said composition containing dehydrocavidine and dehydroapocavine. When necessary, the composition or their crude extracts can be separated by chromatography to obtain dehydrocavidine or dehydroapocavidine. Dehydrocavidine, dehydroapocavidine or their respective composition can be used in manufacturing medicines for treating viral hepatitis, hepatic injury, influenza, AIDS, tumors or arrhythmia.
