20-Deoxyingenol is a natural diterpenoid with the molecular formula C??H??O? and a molecular weight of 332.43 g/mol. Sourced from the root extracts of Euphorbia species (e.g., Euphorbia kansui or Euphorbia lathyris), it appears as a white to off-white crystalline powder and exhibits hygroscopic properties. With a certified purity of ≥98%, it is suitable for research applications in neuroscience and pharmacology. Studies indicate its potential in attenuating neurotoxicity and oxidative stress, particularly in models of morphine-induced cognitive impairment.
