Summary
Quality control of Paeonia lactiflora, a Chinese medicinal herb, found paeoniflorin content varied slightly by processing method but not significantly by growing area. This data aids in standardizing herbal medicine quality.
Area of Science:
- Pharmacognosy
- Botanical Chemistry
- Traditional Chinese Medicine
Background:
- Paeonia lactiflora (Chinese peony) is a vital herb in Traditional Chinese Medicine.
- Ensuring consistent quality of herbal medicines is crucial for therapeutic efficacy and safety.
Purpose of the Study:
- To establish experimental data for the quality control of prepared Paeonia lactiflora.
- To quantify the paeoniflorin content in relation to geographical origin and processing methods.
Main Methods:
- High-Performance Liquid Chromatography (HPLC) was employed to assay paeoniflorin content.
- Paeoniflorin levels were analyzed from samples of Paeonia lactiflora from various growing regions and subjected to different processing techniques.
Main Results:
- Quantitative analysis revealed variations in paeoniflorin content based on growing areas and processing methods.
- Differences in paeoniflorin content among different growing areas were found to be statistically insignificant.
Conclusions:
- Processing methods resulted in quantitative differences in paeoniflorin content within a 10% range.
- The findings provide essential data for the quality control and standardization of Paeonia lactiflora as a medicinal herb.
