[Classification study on commodity specification and grade standard of Pseudostellariae Radix]

Area of Science:

• Pharmacognosy and Phytochemistry
• Agricultural Science
• Quality Control

Context:

• Pseudostellaria Radix is a valuable medicinal herb with significant market presence.
• Current grading systems lack standardization, hindering industrialization and modernization.
• Variability in Pseudostellaria Radix quality necessitates objective classification methods.

Purpose:

• To develop a scientifically validated commodity specification and grade standard for Pseudostellaria Radix.
• To establish objective criteria for classifying Pseudostellaria Radix based on intrinsic quality.
• To support the standardization, industrialization, and modernization of the Pseudostellaria Radix market.

Summary:

• Quantitative analysis of appearance and polysaccharide content across different Pseudostellaria Radix grades was performed.
• Statistical methods including correlation, principal component, and cluster analysis were employed.
• A 5-grade classification system was formulated, based on thickest diameter, single root tuber weight, and root tuber count per 50g, excluding length.

Impact:

• The developed standard provides a reliable basis for Pseudostellaria Radix classification and trade.
• It ensures consistency and reflects the intrinsic quality of the medicinal material.
• Implementation of this standard will facilitate market order and promote industrial development.
