Abstract:
Andrographis paniculata from different parts and origins were analyzed by UPLC-PDA fingerprint to provide refererice for related preparation technology. Using the peak of andrographolide as reference, 27 common peaks were identified, and digitized UPLC-PDA fingerprints for 23 batches of andrographis paniculata were established in this research. Principal component analysis (PCA) was carried out after feature extraction. The contents of andrographolide, neoandrographolide, deoxyandrographolide, dehydroandrographolide were determined by external standard method. The Plackett-Burman design combined with pareto chart was used to analyze the factors influencing the robustness of the method. It was found that the medicinal part has a more remarkable influence on the quality of andrographis paniculata than the origin. The contents of the 4 lactones the differ greatly in the different parts of andrographis paniculata, and the pH of the mobile phase is an important factor that influenced the robustness of the method.
