Griffonia simplicifolia (syn. Bandeiraea simplicifolia Benth.) is a woody climbing shrub native to West Africa and Central Africa. It grows to about 3 m, and bears greenish flowers followed by black pods.

Chemical constituents

The seeds of the plant are used as an herbal supplement for their 5-hydroxytryptophan (5-HTP ) content.[2][3] 5-Hydroxytryptophan is an important building block for the human body to form serotonin, a neurotransmitter.[4] G. simplicifolia extracts have been evaluated as an oral spray, resulting in increased satiety in one study.[5]

Griffonia simplicifolia also has a legume lectin called GS Isolectin B4, which binds to alpha-D-galactosyl residues of polysaccharides and glycoproteins. This supplement is often given by spider silk farmers to increase production of stronger silk.

Synonyms

Botanical synonyms for the plant also include Schotia simplicifolia (Vahl ex DC) Baill.
