Pennisetum spicatum belongs to family Gramineae which is commonly

known as 'Bajara' in Hindi. It is useful in diseases of heart and also used

as an appetizer. Earlier workers have reported various constitutents from

this plant. In the present paper we report the isolation and structural elucidation

of a new cardenolide, m.f. C₃₄H₄₈O₁₄, m.pt. 162-163ºC, which was

identified as 6,7-dehydro-strophanthidin-3-O-β-D-xylopyranosyl (1→2)-α-

L-rhamnopyranoside from the seeds of this plant by various chemical

degradations and spectral analysis.
