This study optimized a sensitive method for determining aucubin using p-dimethylaminobenzaldehyde. The new spectroscopic method accurately quantifies aucubin in Eucommia olive extracts.

Area of Science:

  • Analytical Chemistry
  • Spectroscopy
  • Organic Chemistry

Context:

  • Aucubin is a key iridoid glycoside found in Eucommia ulmoides.
  • Accurate quantification of aucubin is essential for quality control and pharmacological studies.
  • Existing methods for aucubin determination may lack sensitivity or require complex procedures.

Purpose:

  • To develop and optimize a highly sensitive absorption spectroscopic method for aucubin determination.
  • To investigate the influence of critical reaction parameters on the spectroscopic assay.
  • To validate the optimized method for quantifying aucubin in natural product extracts.

Summary:

  • A sensitive absorption spectroscopic method was established for aucubin quantification via condensation with p-dimethylaminobenzaldehyde.
