[Optimal process of Flos Lonicerae in producing area--kill-enzyme torrefaction]

Area of Science:

• Herbal Medicine
• Pharmacognosy
• Agricultural Science

Context:

• Flos Lonicerae (Honeysuckle flower) is a vital traditional Chinese medicine.
• Ensuring consistent quality in Flos Lonicerae production is crucial for therapeutic efficacy.
• Current production methods lack standardization, leading to variable quality.

Purpose:

• To identify the optimal processing method for Flos Lonicerae in its primary production areas.
• To establish a scientific and practical processing technique for stabilizing Flos Lonicerae quality.
• To correlate different processing methods with variations in active compound content.

Summary:

• Kill-enzyme torrefaction significantly enhanced Chlorogenic Acid content by 12.8% compared to sun-drying and 24.9% compared to shade-drying.
• Luteolin-7-glu content was 7.8% higher in kill-enzyme torrefaction samples versus sun-dried and 54.3% higher versus shade-dried.
• Kill-enzyme torrefaction emerged as the superior method for maximizing key bioactive compounds in Flos Lonicerae.

Impact:

• Kill-enzyme torrefaction represents a critical advancement for large-scale Flos Lonicerae cultivation under Good Agricultural Practices (GAP).
• This optimized process provides a scientific basis for producing high-quality Flos Lonicerae.
• The findings support the standardization of herbal medicine processing for improved therapeutic outcomes.
