  • Phytochemistry

Background:

  • Simaba cedron is a plant source of bioactive compounds.
  • Quassinoids are a class of terpenoids with diverse biological activities.

Purpose of the Study:

  • To isolate and characterize novel chemical constituents from Simaba cedron.
  • To elucidate the structure of a new pentacyclic quassinoid.

Main Methods:

  • Extraction of compounds from Simaba cedron wood.
  • Isolation of pure compounds using chromatographic techniques.
  • Structure elucidation using comprehensive spectroscopic methods (NMR, MS).

Main Results:

  • A novel pentacyclic quassinoid, designated cedronolactone E (1), was successfully isolated.
