Microscopic identification of Huangqi Naotong Capsules
Objective To establish a microscopic identification method for Huangqi Naotong Capsules.Me-thod Microscopic identification was used to identify the content and constituent powders of Huangqi Naotong Cap-sules.Three batches of microscopic samples were compared,and 20 parallel experiments were conducted on each sample to obtain the microscopic structural characteristics of the content powder of Huangqi Naotong Capsules and the microscopic characteristic structures of each component.The typical microscopic characteristics were recorded.Results The pollen grains of Carthami Flos,the epidermal cells and setae of Pheretima,and the body wall frag-ments of scorpion were the powder characteristics of corresponding medicinal materials,which could be used as the basis for microscopic identification of Carthami Flos,Pheretima and scorpion in Huangqi Naotong Capsules.Conclu-sion The microscopic identification method used in this study is stable,controllable,and has strong specificity,and can be used as one of the means for quality control of Huangqi Naotong Capsules.
