proximate analyses of Datura innoxia leaf, seed, stem,
pod and root were carried out. Phytochemical screening result
revealed the presence of atropine, scopolamine, essential oils,
saponins, flavonoids, phenols, as well as cardiacs glycosides;
while tannins, coumarins, carboxylic acid and valepotriates were
absent in all the plant parts examined. The proximate analysis
indicated significant (P < 0.05) variation in crude protein
content which ranged from 2.09 in the root to 17.21%, moisture
content (3.5 in root to 15% in stem), crude lipid content was 6%
in root and 15.52% in the seed. Total ash was highest in the
root (25.71%) and least in the seed (8.26%) while nitrogen free
extract was (47.97%) and 20.88% in the pod and stem,
