Abstract:
This article was aimed to study the different clinical characteristics using drug pair of Cassia twig and white peony root with the contents ratio of 1:1 and 1:2. Based on the different clinical treatment of drug pair of Cas-sia twig and white peony root, different compositional ingredients in ratio of 1:1 and 1:2 were illuminated by HPLC/MS method. The drug pair of Cassia twig and white peony roots in ratio of 1:1 and 1:2 and single herbs were ex-tracted for HPLC/MS analysis. A protocol was followed, including acetonitrile - 0.1% acetic acid with gradient elution, positive mode, 350℃ capillary temperature and 300℃ vaporization temperature. The results showed that Procyanidol B2 and 2-Hydroxy cinnamal dehyde can be extracted from single Cassia twig, but 2-Hydroxy cinna-mal dehyde cannot be detected in drug pair. It showed the contents of Procyanidol B2 in 1:1 ratio was more than 1:2 ratio. Simultaneously, Palbinone, paeoniflorin sulfonate, 1,2,3,6-Tetra-O-galloyl-β-D-glucose, Paeoniflorin, Pae-oniflorin isomers, Benzoylpaeo-niflorin, and Benzoyl Paeoniflorin isomers can also be dissolved in white peony root. In addition, the contents of 1,2,3,6-Tetra-O-galloyl-β-D-glucose, Paeoniflorin, Benzoylpaeo-niflorin, and Benzoyl Paeoniflorin isomers in 1:1 were more than 1:2. The contents of Palbinone, paeoniflorin sulfonate and Paeoniflorin isomers in 1:2 were more than 1:1. It was concluded that Procyanidol B2, 1,2,3,6-Tetra-O-galloyl-β-D-glucose, Paeoniflorin, Benzoylpaeo-niflorin and Benzoyl Paeoniflorin isomers in 1:1 were more than 1:2. The contents of Pal-binone, Paeoniflorin sulfonate and Paeoniflorin isomers in 1:2 were more than 1:1. It provided a scientific basis for traditional Chinese medicine treatment using rational drug pair.
