This study is carried out on polysaccharide-based hydrogel extracted from the seeds of Ocimum basilicum L. for its evaluation\nas a superabsorbent and stimuli responsive biomaterial for sustained release drug delivery system. O. basilicum (Syn: Basil) seed\nhydrogel (BSH) expressed high swelling capacity at pH 6.8 and 7.4 and deionized water.Highly reversible on-off switching (swellingdeswelling)\nbehavior of BSHwas ascertained in deionized water and ethanol, pH 7.4 and 1.2, and deionized water and normal saline.\nScanning electron microscopy (SEM) of BSHhas revealed macroporous structure of BSHhaving average pore size of..............
