Caesalpinia echinata Lam

From the extract of the heartwood of Haematoxylon campechianum L. (Leguminosae), a sweet principle was isolated, namely, (+)-hematoxylin (82) [100]. This compound has been used for a long time as a microscopic staining reagent, but the sweetness of this compound was not recognized previously. Also, in the same study, brazilin, the 4-deoxy derivative of (+)-hematoxylin, and a constituent of Caesalpinia echinata Lam. (Leguminosae), was found not to be sweet [100]. In a follow-up study.

Brazilein, a neoflavanoid, is the principal colouring matter in the red dye derived from Caesalpinia species (C. echinata Lam., Brazilwood , and C. sappan L., sappan-wood ). It develops in the rasped wood by autoxidation of a precursor, brazdin (. v. Schweppe, 1992). It is listed in the Colour Index as Cl 75280/Natural Red 24.
