LAPACHOL Chemical Properties,Usage,Production

  • Description Lapachol, a benzoquinone, is a secondary allergen in teak (Tectona grandis).
  • Occurrence Lapacol (CI Natural Yellow 16; CI 75490) (lapachic acid, taiguie acid, tecomin) is a yellow pigment occurring in the wood of trees of the genus Tecoma, native to the West Indies and tropical South America. The shavings of the wood, treated with lime water, give an extract that dyes cotton yellow.
  • Uses antineoplastic, antifungal
  • Uses It was used in the synthesis of the lapachol metal complexes.
  • Uses
    Lapachol was used in the synthesis of the lapachol metal complexes.
  • General Description
    Lapachol is natural naphthoquinone compound derived from Bignoniaceae (Tabebuia sp.).
  • Biochem/physiol Actions Lapachol has antimicrobial properties against many pathogens. It has anti-inflammatory, analgesic and antibiotic properties. It is inhibitor of epithelial tumors in Drosophila melanogaster heterozygote.
  • Contact allergens Lapachol, a benzoquinone, is a secondary allergen in teak (Tectona grandis L., Verbenaceae family), a wood largely used for various indoor and outdoor applications (doors, windows, etc.) because of its strong durability. It has similar reactivity to deoxylapachol. Seealso Chap. 46
  • Purification Methods Crystallise Lapachol from pet ether/EtOH, EtOH or Et2O. [Beilstein 8 H 326, 8 I 644, 8 II 365, 8 III 2720.]
