Abstract:
Objective To establish a multi-index quality evaluation method of Atracylodis Macrocephalae Rhizoma based on principal component analysis (PCA) model.Methods The contents of atractylenolideⅠ and atractylenolideⅢ were determined by HPLC; atractylodes macrocephalaon polysaccharide was determined by phenol-sulfuric acid method; ethanol soluble extractum was determined by hot soak in general rule of Chinese Pharmacopoeia (2015 Edition); PCA was used to establish a multi-index quality evaluation model. Results AtractylenolideⅠ and atractylenolideⅢ showed good linear correlations (r=0.999 9), and the average recoveries were 100.9% and 102.1%, respectively. PCA showed that the Atracylodis Macrocephalae Rhizoma from Panan County, Yuqian Town, Jinyun County, Xinchang County of Zhejiang Province had the best quality, from Bozhou City and Fuyang City of Anhui Province had good quality.Conclusion The established multi-index quality evaluation method based on PCA model can be applied to objectively evaluate the quality of Atracylodis Macrocephalae Rhizoma from different producing areas.
