Study on GC fingerprint of Magnoliae Flos and Asari Radix et Rhizoma in Liujing Toutong Tablets / 中草药

ABSTRACT

Objective To establish the fingerprint of Magnoliae Flos and Asari Radix et Rhizoma of Liujing Toutong Tablets (LTT), provide the basis for the evaluation of the quality of LTT. Methods Aglient DB-WAX (20 m × 0.18 mm, 180 μm) gas chromatography column, select the appropriate temperature conditions, the determination of the 11 batch of Magnoliae Flos, Asari Radix et Rhizoma, the use of SPSS clustering analysis and chromatographic fingerprint evaluation system (2004A version) the establishment of Xinyi medicine fingerprints, and through the Agilent 7890A-5975C gas quality for instrument on the common peaks were identified. Results The 11 batches of samples were measured and SPSS cluster analysis of 10 batches of medicinal materials were clustered into one group, and the establishment of Xinyi medicine GC fingerprint, the similarity was more than 0.9, a total of 22 common peaks, which belongs to the whole party into 14 components, medicinal unique ingredients 8; 10 batches of Asarum medicinal materials were clustered into one group, and the establishment of Asarum GC fingerprint, the similarity was more than 0.9, a total of 11 common peaks, which belongs to the whole Party composition for 4, 7 for a particular component of medicinal materials. Conclusion This method has strong specificity, high accuracy, good repeatability, and provide the basis for quality control of Herba Magnoliae Flos and Asari Radix et Rhizoma.
