The seeds are reported to contain 342 calories per 100 grammes; water 12 grammes; protein 10grammes; fat 3.7 grammes; fibre 2.2 grammes; ash 1.5 grammes; calcium 22mg; phosphorus 242mg; iron 3.8mg; sodium 8mg; Thiamine (B1) 0.33mg; riboflavin (B2) 0.18mg; niacin 3.9mg etc.

Sorghum bicolor seeds contain butyric, formic, myristic, palmitic and stearic acids. It also contains maltose and emulsine. Sorghum bicolor contains cyanides, alkaloids, tannins and cyanogenetic glycosides. Cyanogenic glycosides is also called nitrilosides or vitamin B17 and this is believed to fortify sickle cell persons against crisis.

Sorghum bicolor contains high concentration (26 per cent) of P-hydoxybenzaldehde 7, the compound which increase oxygen affinity of Hbs like all aldehydes.

TOXICITY OF SORGHUM BICOLOR HERBAL PREPARATIONS/DRUGS

Sorghum bicolor contains hydrocyanic and alkaloid hordenine which are poisonous, if taken in large quantity. Cyanide can become an intoxicant when sorghum bicolor is made to undergo fermentation and this could make the consumer to exhibit neurological syndromes such as Lathyrism, Parkinsonism and Dementia. There is however no evidence that the percentage of cyanide contains in the sorghum bicolor is significant enough to make it poisonous when it is administered but the intake should be with moderation. Too much cyanide can engender goiter disease, can retard growth and can hinder mental development in early childhood especially when the child suffers nutritional deficiencies. Improved or quality nutrition could suppress the likely negative effects of cyanide in little kids.

However, fermentation of sorghum bicolor seeds alone for seven days according to Ogunyemi (2004) can intoxicate and can as well serve as good anti-sickling drug following the report of his M. Phil Thesis at Obafemi Awolowo University , Ile – Ife , Nigeria .
