无机元素,是动植物发育及生命活动不可须臾或缺的,并且还对植物体内有机物质的合成及其代谢、动物体内骨骼的形成、肌肉运动,能量代谢等方面,都有重要作用。本研究对人参、柴胡、麻黄、茯苓等中药处方常用生药中的Ca、Na、K等无机元素及其含量进行了分析测定。实验方法 1.供试样液的制备; ①取各种生药微细粉末干燥品约0.5克,用低温灰化器灰化,将残留物溶解于3毫升王水中,加水至全量100毫升。②取人参微细粉末干燥品约5克,加水 Inorganic elements are important for the development of animals and plants and their vital activities. They also play an important role in the synthesis and metabolism of organic substances in plants, the formation of bones in animals, muscle movement, and energy metabolism. In this study, Ca, Na, K and other inorganic elements and their contents in crude drugs commonly used in traditional Chinese medicine prescriptions such as ginseng, bupleurum, ephedra, and wolfberry were analyzed. Experimental method 1. Preparation of sample solution; 1 Take about 0.5 grams of dried powder of various crude drug powders, ash with a low-temperature ashing device, dissolve the residue in 3 ml of aqua regia, and add water to the entire volume of 100 ml. 2 Take about 5 grams of ginseng fine powder dry product, add water
