Starchy and non‐starchy carbohydrates of samai, sanwa and panivaragu have been isolated and characterized. Starch isolated exhibited single stage swelling, moderate solubility in water, but a very high solubility in DMSO, and non‐ionic character similar to several starches from Leguminoseae . Treatment with mild alkali resulted in the separation of big‐hexagonal, and small‐spherical granules. Considerable retrogradation of the linear amylose fraction was observed. Hemicellulose A was shown to be a non‐cellulosic glucan, whereas hemicellulose B was composed of hexoses, pentoses and uronic acids in varying proportions. The alkali‐insoluble residues were exclusively composed of glucose and thus constituted the fibre fraction.
