中成药多使用粉末生药,在中成药的质量管理中.对生药的鉴定,镜检是简单、有效的手段。下村等已报告了目前通过镜检对制剂中所含粉末生药的鉴定法,此次为了更准确地运用该镜检法,研究了偏光镜的应用。 使用从产地直接购进的、已经过鉴定的中成药及际准生药,将其粉碎成细末,制成显微镜用载片标本。使用显微镜、全自动摄影装置及偏光镜,以400倍的倍率摄影。在对14种 Traditional Chinese medicines use more powdered crude drugs. In the quality management of proprietary Chinese medicines, identification of raw drugs and microscopic examination are simple and effective methods. Shimomura et al. have reported on the identification of powdered crude drugs contained in preparations through microscopic examination. In order to more accurately use this microscopic examination, the application of polarizers was studied. Using proprietary Chinese medicines and quasi-experimental medicines that were directly purchased from the place of production, they were crushed into fine powders and made into microscope slide specimens. Using a microscope, a full-automatic photography device, and a polarizer, photography is performed at a magnification of 400 times. In 14 kinds
