Plantasan, the seed mucilage of Plantago major L. var. asiatica DECAISNE, has been subjected to partial acid hydrolysis, and three disaccharides were obtained. Analysis of components, periodate oxidation, methylation and enzymic degradation studies provided the evidences that they are O-β-D-xylopyranosyl-(1→2)-D-xylopyranose, O-β-D-xylopyranosyl-(1→4)-D-xylopyranose, and O-β-D-glucopyranosyl-uronic acid-(1→5)-L-arabino-furanose.
