[Study on the composition and pharmacological function change of rhizoma polygonati before and after processing]

Area of Science:

• Pharmacology
• Traditional Chinese Medicine
• Chemical Analysis

Context:

• Rhizoma Polygonati (RP) is a traditional Chinese medicine with various pharmacological effects.
• The processing of herbal medicines can alter their chemical composition and biological activity.
• Understanding the processing mechanism is crucial for optimizing therapeutic efficacy.

Purpose:

• To investigate the processing mechanism of Rhizoma Polygonati (RP).
• To correlate changes in chemical composition with pharmacological function in raw and processed RP.
• To elucidate the role of 5-Hydroxymethylfurfural in the enhanced immune function of processed RP.

Summary:

• High-performance liquid chromatography (HPLC) was used to compare the extraction profiles of raw and processed RP.
• A significant increase in 5-Hydroxymethylfurfural concentration was observed in processed RP.
• Processed RP demonstrated markedly enhanced immune function, evidenced by increased carbon clearance index and coefficient of phagocytosis.

Impact:

• The study reveals that the increased immune function of processed RP is likely due to the elevated levels of 5-Hydroxymethylfurfural.
• Provides a scientific basis for the traditional processing of RP.
• Offers insights into optimizing the production of herbal medicines for improved therapeutic outcomes.
