Detection method of radix cyathulae medicinal material

The invention discloses a detection method of a radix cyathulae medicinal material. According to the detection method, an HPLC (High Performance Liquid Chromatography) graph of a sample is determinedby adopting high-performance liquid chromatography, and the similarity and characteristic peak difference between the obtained graph and a radix cyathulae HPLC fingerprint graph are compared. According to the detection method disclosed by the invention, a multi-wavelength switching technology is adopted and the contradiction that various components cannot be wholly detected under the single wavelength when the absorption wavelength difference is great is solved; the detection method disclosed by the invention is used for authenticity identification of the radix cyathulae medicinal material, has high sensitivity and is efficient and accurate. 本发明公开了种川牛膝药材的检测方法，采用高效液相色谱法测定样品HPLC图谱，并比较所得图谱与川牛膝HPLC指纹图谱的相似度和特征峰差异。本发明检测方法运用多波长切换技术，解决了多组分因吸收波长差异大而无法在单波长下全部检出的矛盾，本发明检测方法用于川牛膝药材的真伪鉴别，灵敏度高、高效准确。
