Abstract
Abstract A novel acidic heteropolysaccharide which comprises as its structural units arabinose, mannose, galactose, glucuronic acid, and xylose, at a specific ratio. The polysaccharide can be prepared by culturing a callus induced from a plant belonging to the genus Polianthes L. in a culture medium containing plant hormones. The polysaccharide can be used as a component of agents for external application and detergents, and provides good moisturizing effects and a smooth, satisfying feeling upon use. When formulated in detergents, they produce remarkable improvement in a clean, rich feeling upon use.
