[Quality assessment on schisandrae fructus from different habitats]
Summary
This study quantified five lignans in Schisandrae Fructus from various locations. Principal component analysis and hierarchical clustering classified samples, aiding quality assessment and resource management.
Area of Science:
- Phytochemistry
- Chemometrics
Context:
- Schisandrae Fructus is a traditional medicinal herb with variable chemical composition.
- Assessing the quality of herbal medicines is crucial for efficacy and safety.
Purpose:
- To quantify five key lignans (Schizandrol A, Schizandrol B, Schisantherain A, deoxyschizandrin, and gamma-schizandrin) in Schisandrae Fructus samples.
- To classify and evaluate the quality of Schisandrae Fructus based on lignan content using chemometric methods.
Summary:
- A High-Performance Liquid Chromatography (HPLC) method was established to quantify five lignans in 30 batches of Schisandrae Fructus.
- Hierarchical clustering analysis (HCA) and principal component analysis (PCA) were employed to group samples based on their lignan profiles, revealing three distinct quality-related clusters.
- The analysis demonstrated that lignan content varies significantly across different habitats, impacting the overall quality characteristics.
Impact:
- Provides a robust analytical framework for the quality control of Schisandrae Fructus.
- The classification based on lignan profiles supports the rational utilization and conservation of Schisandrae Fructus resources.
- Offers valuable data for standardizing herbal medicines derived from Schisandrae Fructus.
