    The national drug sampling and inspection project is an important way of drug quality supervision in China which providing strong support for drug supervision and standard improvement. This article summarizes the national drug sampling and inspection project of Arnebiae Radix completed by Institute for Control of Chinese Traditional Medicine and Ethnic Medicine,National Institutes for Food and Drug Control in 2015 and 2022. The results illustrated that the qualification rate of Arnebiae Radix has increased from 43.9% in 2015 to 87.5%,and the qualification rate of Arnebiae Radix has significantly increased. The two nationwide inspections of Arnebiae Radix reflected the scarcity of Arnebiae Radix resources in Xinjiang and Inner Mongolia,resulting in a high market share of unqualified samples. The thin layer identification spots of the unqualified Arnebiae Radix sampled in 2015 were not consistent with the qualified samples. The thin layer identification of the unqualified samples sampled in 2022 was consistent with those of the qualified samples,but the depth of the spots were not consistent with those of the qualified samples,indicating that the current unqualified samples were adulterated samples,which posing greater challenges to the quality supervision of Arnebiae Radix. Through the exploratory research of twice National Drug Sampling and Inspection Project,it is preliminarily believed that it is of great significance to improve the standard test items of Arnebiae Radix,scientifically establish the limit value and strengthen the construction of the quality control system for the supervision.

    Objective:

    To compare the quality of wild and cultivated Arnebiae Radix,using macroscopic investigation and chemometric analysis of the different components in wild and cultivated Arnebiae Radix from three different habitats.

    Methods:

    Wild and cultivated Arnebiae Radix were collected and their macroscopic features were compared. Using the ACQUITY UPLC BEH C18 (2.1 mm×100 mm,1.7 μm) column,with acetonitrile-0.05% formic acid water as the mobile phase,the contents of D-shikonin,acetylshikonin,β-acetoxyisovalerylshikonin,isobutyrylshikonin,β,β’-dimethylacrylalkannin and isovalerylshikonin in 48 batches of wild and cultivated Arnebiae Radix were determined. The detection wavelength was 275 nm and the flow rate was 0.2 mL·min-1. PCA and OPLS-DA were performed to reveal the differential components of wild and cultivated Arnebiae Radix.

    Results:

    There were great differences in macroscopic features of wild and cultivated Arnebiae Radix,and the linear relationship between the contents of six naphthoquinone components was good. The correlation coefficients were above 0.999,the average recovery rates were 93.4%-102.9%,and the RSDs were less than 3.0%. The contents of six components in different batches of wild and cultivated Arnebiae Radix were quite different,and the contents of D-shikonin and acetylshikonin in wild products were significantly higher than those in cultivated products,indicating that there were still certain differences between wild products and cultivated products. The PCA model established could distinguish wild products and cultivars,and two differentiating components in wild products and cultivars were revealed by OPLS-DA,namely isobutyryl shikonin,β,β’-dimethylacrylalkannin.

    Conclusion:

    By comparing the core size,cork curl degree and specific odor of wild and cultivated products,the two can be identified. The established content determination method is repeatable,specific,stable and feasible. The differential components in wild and cultivated Arnebiae Radix in three different regions are identified,which provides a basis for the quality control of Arnebiae Radix and provides ideas for expanding the source of Arnebiae Radix.
