Withenia Somnifera

Chemical constituents:
The plant is very rich in tropane alkaloids and steroidal lactone, withanolides. Roots contain tropine, pseudotropine, tigloyloxytropine, choline, anaferine, pellectierine, isopelletierine, anahygrine and cuscohygrine. Root also contain nicotine, somnigerine, somniferinine, withamine, withananine, pseudowithanine, withaferin A and B, withasomidienone, sominone, sominolide, β-sitosterol, sugar and acidic compounds. Five new withanolides, namely withasomnilide, somniferawithanolide, withasomniferabolide, somniferanolide and somniwithanolide, have been isolated from the stem bark (Ghani, 2003). Nine new withanolides E to M have been isolated from leaves. Another withanolides WS-1 has been isolated from seeds (Rastogi & Mehrotra, 1993). Leaves also contain 8 steroidal lactones, somnitol, glucose, inorganic salts and new compounds – withanone and withaferin A along with its dihydro derivative (Rastogi & Mehrotra, 1990).
