[Influence of processing factors on honey-fried Codonopsis Radix]

Area of Science:

• Pharmacology
• Traditional Chinese Medicine
• Food Chemistry

Background:

• Codonopsis Radix is a traditional Chinese herb with various pharmacological effects.
• Honey-frying is a processing technique used to modify the properties of herbal medicines.
• Understanding the impact of honey-frying on Codonopsis Radix is crucial for optimizing its therapeutic potential.

Purpose of the Study:

• To investigate the effects of heating and honey addition on the appearance, chemical composition, and in vitro antioxidant activity of Codonopsis Radix.
• To explore the processing mechanism of honey-fried Codonopsis Radix.

Main Methods:

• Comparative analysis of raw, fried, honey-mixed, and honey-fried Codonopsis Radix samples.
• Determination of color, sweetness, and content of key components (oligosaccharides, polysaccharides, lobetyolin, atractylenolide III).
• In vitro antioxidant activity assays (ABTS radical scavenging) of water, polysaccharide, and oligosaccharide extracts.

Main Results:

• Honey-frying significantly altered color and sweetness compared to raw Codonopsis Radix.
• Heating and honey addition reduced the content of lobetyolin, atractylenolide III, and polysaccharides.
• Honey addition increased oligosaccharide content.
• Honey-fried Codonopsis Radix exhibited the most potent in vitro antioxidant activity.

Conclusions:

• Both heating and honey addition influence the characteristics and activity of Codonopsis Radix.
• The combination of honey addition followed by high-temperature heating is optimal for enhancing the pharmacological activity of Codonopsis Radix.
• Honey-frying is an effective method to improve the antioxidant properties of Codonopsis Radix.
