Abstract

To establish a scientific method for identitication and evaluation of the Tibetan prescription Jia Ga Song Tang. Volatile oil was extracted by water steam distillation and analyzed by GC-MS. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) were applied to the samples for chemical fingerprint pattern recognition research. 16 samples according to hierarchical cluster analysis (HCA) and principal component analysis (PCA) were divided into two classes, and results from two recognition analysis methods had good consistency. GC-MS-pattern recognition method was a kind of scientific, accurate and effective method for the quality evaluation of Jia Ga Song Tang.
