Area of Science:

  • Analytical Chemistry
  • Natural Product Chemistry
  • Materials Science

Background:

  • Flavonoids are valuable compounds found in medicinal plants like Dendrobium huoshanense.
  • Efficient extraction methods are crucial for analyzing these bioactive compounds.
  • Developing sustainable and cost-effective adsorbents is an ongoing challenge.

Purpose of the Study:

  • To prepare and utilize mangosteen peel-based activated carbon as an adsorbent for flavonoid extraction.
  • To develop a simultaneous extraction method using matrix solid-phase dispersion (MSPD).
  • To determine flavonoids from Dendrobium huoshanense using UHPLC-Q-TOF/MS.

Main Methods:

  • Preparation of activated carbon from mangosteen peel.
  • Application of matrix solid-phase dispersion (MSPD) for simultaneous extraction.
  • Ultra-high performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (UHPLC-Q-TOF/MS) for analysis.
  • Method validation including linearity, limit of detection, and recovery studies.

Main Results:

  • The developed MSPD-UHPLC-Q-TOF/MS method showed good linearity (r² ≥ 0.9929) for target analytes.
  • Limits of detection ranged from 0.00387-0.159 μg/g.
  • Satisfactory recoveries for six target compounds were achieved (80.02-99.49% and 85.32-99.86%).
  • Mangosteen peel activated carbon proved to be less expensive and more environmentally friendly than common sorbents.

Conclusions:

  • The proposed method is simple, efficient, low-cost, eco-friendly, time-saving, and sensitive.
  • It is suitable for the extraction and determination of flavonoids in complex matrices.
  • Mangosteen peel-based activated carbon is a promising adsorbent for natural product analysis.
