Gbolo (C. crepidioides and C. rubens) is a wild or semi-domesticated aromatic
traditional leafy vegetable highly consumed in Benin. The vegetable was said to have
medicinal values and locally used as nutraceutical. Considering the scientifically
established potential toxicity of some vegetable species to humans and animals, leaves
extracts of C. crepidioides and C. rubens were subjected to qualitative phytochemical
screening and testing for cytotoxicity using the brine shrimp lethality bioassay. The
phytochemical screening recorded the presence of pharmacologically important
substances such as tannins, coumarins, combined anthracene derivatives C-heterosides,
flavonoids, mucilage, reducing compounds and Steroids. Alkaloids, anthocyanins,
quinone derivatives, saponins, triterpenoids, cyanogenic derivatives, cardiac glycosides
and anthracene derivatives (except anthracene derivatives C-heterosides) were not
detected. The LC50 values of the leaves extracts were found to be 0.901 mg/ml for C.
crepidioides and 0.374 mg/ml for C. rubens hence indicating the non-toxicity of both
species. The outcome of this study lends support to the trado-medicinal uses of
vegetable Gbolo in the treatment of various ailments in Benin and indicates the
potential usefulness of this vegetable as nutraceutical to prevent or treat various
diseases. However more studies are needed for the validation of the antimicrobial, antidiabetic,
anti-inflammatory and blood pressure regulation properties attributed by the
local communities to this vegetable Gbolo |
