Description

The coco, also cochucho or smelly sauco, is usually found either in isolated groups or standing alone. It's a small to medium sized tree, ranging 6 to 8 m high. The folliage is abundant, evergreen with imparipinnate leafs that present paired spines presumably in the place of leaflets. Punctations, in pairs, on the leaflets are quite notable. Leafs have serrated margins and pinnate venation. Flowers have five petals and are arranged in panicular inflorescences. The fruit is spheric shaped, dehiscent; containing a shiny blackish seed.[1] The whole plant has a characteristic unpleasant smell; there comes "smelly sauco" as another common name.[2]

Biochemistry

Even though unused in general botanical pharmacopea, Zanthoxylum coco tissues are very rich in alkaloids. Fagarine, N-methylisocoridine, eskimminianine, α-fagarine, fagarine-2, magnoflorinne, nitidine, cheleritrinne, berberine, palmatine and candicine have been isolated from folliage and wood.[3]

Taxon synonym usage

The coco belongs to the Zanthoxylum genus. However, most local scientific articles use Fagara as the genus of choice.
