[Study on quality standards for Lingmaoxiang Jiedu pills]

Area of Science:

• Pharmacology and Traditional Chinese Medicine
• Analytical Chemistry
• Quality Control

Context:

• Linmaoxiang Jiedu pills are a traditional Chinese medicine formulation.
• Establishing robust quality standards is crucial for ensuring the safety and efficacy of herbal medicines.
• High-Performance Liquid Chromatography (HPLC) is a standard analytical technique for compound quantification.

Purpose:

• To establish quality standards for Linmaoxiang Jiedu pills.
• To develop and validate a simultaneous High-Performance Liquid Chromatography (HPLC) method for quantifying cinobufagin and bufogenin.
• To ensure the consistent quality and therapeutic reliability of the medicinal product.

Summary:

• A validated High-Performance Liquid Chromatography (HPLC) method was developed for the simultaneous determination of cinobufagin and bufogenin in Linmaoxiang Jiedu pills.
• The method demonstrated high average recoveries (100.5% for cinobufagin, 100.3% for bufogenin) and suitable linear ranges (48.74-731.10 ng for cinobufagin, 49.90-748.50 ng for bufogenin).
• The analytical method is reproducible, realizable, and suitable for establishing quality standards for Linmaoxiang Jiedu pills.

Impact:

• Provides a reliable analytical method for the quality control of Linmaoxiang Jiedu pills.
• Contributes to the standardization and quality assurance of traditional Chinese medicine.
• Supports the consistent production of safe and effective Linmaoxiang Jiedu pills for therapeutic use.
