Genipa americana

Figure 4 Carajurone (R=CHs) and the related carajuretin (R=H) result by the very rapid enzymatic aerial oxidation of flavans present in the leaves of Arrabidaea chica. The plant is one of the most used Amazonian medicinal plants and the anti-microbial and other activities may be related to the presence of these red pigment. Some indigenous tribes use them as face paints and carajurone has been commercialised in the past as chica red. Genipa americana fruit juice, by the action of an endogenous glucosidase followed by aerial oxidation, provides another pigment. The juice has multiple medicinal uses probably associated with its antimicrobial action. Here the dye is blue-black and is believed to be an ethylene-bis- -aza-azulene , derived by condensation of the genipin monomer with primary amines. ...

From the fruit of the Puerto Rican plant Genipa americana L.y Tallent (1964) isolated the cyclopentanoid antibiotic genipic acid, C9H12O4. From its spectral properties and reactions [especially a chemical correlation with aucubin (VIII)], he deduced the structure I for it, except for the absolute configuration, which has only recently been established for aucubin (VIII) and therefore genipic acid (I).
