This study compared alcohol, water, and sequential alcohol-water extraction methods for Hirudo. A novel compound Hirudo oral liquid preparation method was developed based on extraction efficiency and pharmacological activity.

Area of Science:

  • Pharmacology
  • Biochemistry
  • Traditional Chinese Medicine

Context:

  • Hirudo (leech) is a component in traditional oral liquids.
  • Optimizing extraction methods is crucial for maximizing therapeutic compounds.

Purpose:

  • To compare the extraction efficiency of different solvents (alcohol, water) for Hirudo.
  • To evaluate the pharmacological activity of compound Hirudo oral liquid.
  • To establish an improved preparation method for Hirudo oral liquid.

Summary:

  • Extraction efficiency varied significantly between alcohol, water, and sequential alcohol-water methods for Hirudo.
  • Pharmacological activity and nitric substance content were key markers for evaluation.
  • A new preparation method for compound Hirudo oral liquid was successfully established based on experimental findings.
