Ispaghula seed

ISPAGHULA SEED, Psyllii semen The drug is obtained from Planta o ovata, Forskal,... 

Plantago ispaghula, or Light Indian Psyllium, is cultivated in India. Seeds are boatshaped, with one end sharper than the other, and grey-brown in colour, A small brown spot is a feature of the convex side. Transparent mucilage surrounds the seeds when kept in water. 

Plantago seeds are widely used as bulk laxatives under the names of psyllium (from P. psyllium or P. indica) and ispaghula (from P. ovata). The possibility that the intestinal absorption of lithium and other drugs may be inhibited should also be considered (658). 

Bulk-forming laxatives contain ispaghula husk (the seed coats of a species of plantain), sterculia (a gum from a tropical shrub) or methylcellulose (a semisynthetic hydrophilic colloid).

Alkaline extraction of the husks of Ispaghula has yielded a highly branched acidic L-arabino-D-xylan. The polysaccharide is unusual in containing both (l->3)- and (14)-D-xylose residues in the main chain with the majority of residues further substituted at 0-2 or 0-3 with residues of L-arabinose, D-xylose, or D-galactopyranosyluronic acid-(l2)-L-rhamnose. Another acidic polysaccharide, based on a (14)-D-xylan main chain has been isolated from the seeds of Ocimum basilicum The polysaccharide contained D-xylose, L-arabinose, L-rhamnose, and D-galacturonic acid in the molar ratio 15 9 7 12 and the branch points were present at both 0-2 and 0-3 of the D-xylose residues in the main chain. Two oligosaccharide sequences, (15) and (16), were isolated from the side chains.
