A composition for curing autoimmune diseases is disclosed. The composition comprises as an effective component an acidic heteropolysaccharide which is secreted by a callus induced from a plant belonging to the genus Polianthes L. The acidic heteropolysaccharide can be prepared as a uniform product by the application of plant tissue culture methods and exhibits superior capability of removing immunocomplexes with the least side effects.

An extracted peach-leaf fraction, preparation method of the same and a bath-additive composition comprising the same is disclosed. The extracted peach-leaf fraction is prepared by extracting peach-leaves with water and/or a lower alcohol, and treating the obtained extract with activated charcoal. The peach-leaf fraction of the present invention has an excellent solubility and stability when dissolved in water, a high anti-inflammatory effect, and safety to the skin. Further, the bath-additive composition comprising the peach-leaf fraction has an excellent bathing effect without making the bath water turbid.

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.
