Four new limonoid derivatives were isolated from Citrus sudachi seeds. These compounds, including 1-O-methylichangensin and sudachinoids A-C, were structurally identified using spectroscopic and chemical methods.

Area of Science:

  • Natural Product Chemistry
  • Phytochemistry
  • Organic Chemistry

Background:

  • Citrus sudachi seeds are a potential source of bioactive compounds.
  • Limonoids are a class of terpenoids with diverse biological activities.

Purpose of the Study:

  • To isolate and characterize new limonoid derivatives from Citrus sudachi seeds.
  • To elucidate the structures of novel compounds using spectroscopic and chemical techniques.

Main Methods:

  • Extraction of compounds from Citrus sudachi seeds.
  • Purification using chromatographic techniques.
  • Structure elucidation via Nuclear Magnetic Resonance (NMR) spectroscopy, Mass Spectrometry (MS), and chemical reactions.

Main Results:

  • Four new limonoid derivatives, 1-O-methylichangensin (1), sudachinoid A (2), sudachinoid B (3), and sudachinoid C (4), were isolated.
  • Known compounds ichangensin, obacunone, obacunoic acid, and limonin were also identified.
  • The structures of the new compounds were confirmed through comprehensive spectroscopic and chemical analyses.

Conclusions:

  • The seeds of Citrus sudachi contain a rich source of structurally diverse limonoids.
  • The identification of these novel compounds contributes to the understanding of Citrus secondary metabolites.
  • Further investigation into the biological activities of these isolated limonoids is warranted.
