Objective:Comprehensively compare and evaluate quality of Guizhou Lysionotus pauciflorus. Method: HPLC method and UV method were used on different orgin of Guizhou

different harvest time

different processing method for determination of the origin of L. pauciflorus

for two kinds of chemical composition method

by using principal component analysis and comprehensive quality evaluation comparative study. Result: When the L. pauciflorus products in the Yongzheng

cold blunt village and reaps in July and is dryed

its comprehensive quality was best. Conclusion: Different origin

different harvest time

different processing method of the origin of L. pauciflorus affect the quality deeply. The study results provide certain scientific basis for the comprehensive quality of L. pauciflorus and variety breeding

base construction of GAP

the rational development and utilization of medicinal materials.
