摘要: Paris polyphylla var. yunnanensis (Franch.) Hand.-Mazz (PPY) is used widely as an anthelmintic, antimicrobial, and anti-tumor agent. Multiplicate analytical methods have been employed to discriminate PPY from different regions, as well as to identify regions most beneficial to the growing of this species. In this study, a convenient and accurate method was established using ultra high performance liquid chromatography (UHPLC) for simultaneous determination of four steroid saponins (Pa, Pb, polyphyllin VI, and chonglou saponin VII). Partial least squares discriminant analysis (PLS-DA) according to UHPLC and UV spectroscopy was applied to analyze 30 samples of PPY from three regions of Yunnan Province in China, and identify significant peaks. The results indicated that the correlation coefficients (r (2)) of all calibration curves were above 0.999, and the inter- and intra-day relative standard deviations (RSD) of retention time and peak areas of common peaks were below 1.78 % and 3.40 %, respectively, with recovery rates of 99.6-103.4 % with RSD ae2 %. Quantitative analysis implied that the average values of total saponins in PPY from south Yunnan Province (19.9 mg/g) were higher than in the central (8.79 mg/g) district. Thus, further investigation could focus on the southern region to seek high quality PPY. The analysis found that PLS-DA for ultraviolet (UV) spectroscopy, which could separate the samples from three regions, was more appropriate than UHPLC. Retention times during 20-30.75 min of UHPLC, and absorption at 200-300 nm of the UV spectrum were identified as significant peaks for distinguishing PPY from different regions.
