This study was aimed to analyze the correlation between commercial specifications of Panacis Quinquefolii Radix and quantitative indexes of sevent kinds of ginsenosides (ginsenosides Rg¹, Re, Rb¹, Rc, Rb₂, Rb₃, Rd) contained in Panacis Quinquefolii Radix by using high performance liquid chromatography (HPLC), explore the correlation between the characteristics of the traditional Panacis Quinquefolii Radix specifications and modern chemical quantitative indicators, and provide a theoretical basis for the quality grade evaluation of Panacis Quinquefolii Radix. The HPLC fingerprint method was used to analyze 40 batches of Panacis Quinquefolii Radix. A total of 19 peaks were marked, and the similarity was above 0.900 for all samples. On this basis, processing methods, product specifications, contents of 7 components, and the total contents of ginsenoside Rg¹, Re and Rb¹ were used as the original variables for cluster analysis and principal component analysis. The results showed great correlation between the quality of Panacis Quinquefolii Radix and the information on their origins, but the difference was less with the characteristics of traditional commercial specifications, indicating some limitations in the division of commercial specifications of Panacis Quinquefolii Radix. The results revealed the intrinsic relationship between the product specifications, traditional qualitative indexes, and quantitative indexes of chemical components of Panacis Quinquefolii Radix, providing a new idea for the objective comprehensive evaluation of the quality of Panacis Quinquefolii Radix.

This study investigated the anti-gastric cancer activity and mechanism of Panacis Quinquefolii Radix(Panax quinquefolium L.), and preliminarily compared the in vivo anti-gastric cancer efficacy of American-imported(JK-AG) and domestically produced(Shandong) Panacis Quinquefolii Radix decoctions(SD-AG). Based on network pharmacology predictions, a LUC-MGC803 cell ectopic gastric cancer nude mouse model was established.

Ginseng Radix et Rhizoma and its preparations are often adulterated with Panacis Quinquefolii Radix. Based on the research on Ginseng Radix et Rhizoma and Panacis Quinquefolii Radix, the causes and analytical method of adulteration were determined. A UPLC-MS/MS method was developed for the detection of Panacis Quinquefolii Radix mixed in Ginseng Radix et Rhizoma, with pseudoginsenoside F_(11) as the marker.

Objective: (ASR, Danggui in Chinese), (CH, Roucongrong in Chinese), et (PG, Renshen in Chinese), and (PQ, Xiyangshen in Chinese), widely used as medicine and dietary supplement around the world, are susceptible to fungal and mycotoxin contamination. In this study, we aim to analyze their fungal community by DNA metabarcoding.
Methods: A total of 12 root samples were collected from three main production areas in China.
