Abstract

Insights

Cornus officinalis administration allows 5-hydroxymethylfurfural (5-HMF) to enter rabbit neurolymph, crossing the blood-brain barrier (BBB). UPLC-MS detected 5-HMF at lower doses than HPLC, indicating higher sensitivity.

Area of Science:

  • Pharmacology
  • Neuroscience
  • Analytical Chemistry

Background:

  • Cornus officinalis is a traditional herbal medicine.
  • 5-hydroxymethylfurfural (5-HMF) is a key compound in Cornus officinalis.
  • The blood-brain barrier (BBB) restricts the passage of substances into the central nervous system.

Purpose of the Study:

  • To investigate the detection of 5-HMF in rabbit neurolymph.
  • To determine if 5-HMF from Cornus officinalis can cross the BBB.
  • To compare the sensitivity of HPLC and UPLC-MS in detecting 5-HMF in neurolymph.

Main Methods:

  • Rabbits were administered low, medium, and high doses of Cornus officinalis intragastrically.
  • Rabbit neurolymph was collected three days post-administration.
  • 5-HMF levels in neurolymph were analyzed using High-Performance Liquid Chromatography (HPLC) and Ultra-Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS).

Main Results:

  • 5-HMF was detected by HPLC only in rabbits receiving the high dose of Cornus officinalis.
  • 5-HMF was detected by UPLC-MS in rabbits receiving medium and low doses of Cornus officinalis.
  • UPLC-MS demonstrated higher sensitivity in detecting 5-HMF in rabbit neurolymph compared to HPLC.

Conclusions:

  • 5-HMF can penetrate the rabbit blood-brain barrier (BBB).
  • Cornus officinalis derived 5-HMF enters the rabbit neurolymph.
  • UPLC-MS is a more sensitive method for detecting 5-HMF in neurolymph at lower concentrations.
