Abstract: A water-soluble polysaccharide gel having good immuno-stimulating activity was extracted from fruit-rind of durian (Durio zibethinus Murr.) Food supplement having immuno-stimulating activity for feeding black tiger shrimp or chicken were prepared using the polysaccharide gel isolated from durian fruit-rind.

Abstract: A water-soluble polysaccharide gel having good gelling property and good antimicrobial activity was extracted from fruit-rind of durian (Durio zibethinus Murr.) comprises steps of boiling dried fruit rind with 25-30 volumes by weight of water, filtering, repeating boiling residue 1-2 times with 15 volume by weight of water. Filtrates were pooled and concentrated by rotary evaporating at 70° C. under reduced pressure and precipitating using acidified aqueous ethanol, collecting precipitate, spray-drying or drying and pulverizing. Pharmaceutical preparations were prepared using the polysaccharide gel such as anti-acne preparations, alcohol-free hand sanitizer preparation and wound antibacterial gel preparation.

Abstract: Botanical compositions are described having hypoglycemic, hypolipidemic and antimicrobial activity for maintaining good health in normal person and diabetic person comprising water extract of two medicinal plants, dried leaves of Malvastrum coromandelianum and/or dried stems of Coscinium fenestratum. The extracts are used separately or in combination of fixed amount or varied amounts, as herbal beverage or in different pharmaceutical preparations.

Abstract: A process for isolation and purification of polysaccharide gel and fiber from dried fruit-hull of Durio zibethinus L. Two polysaccharide products are obtained. The process involves hot water extraction of crude polysaccharide gel from fruit-hulls, filtration and precipitation in acid-lower aliphatic alcohol and further purification by reprecipitation of concentrated aqueous crude polysaccharide gel, after demineralization using cation-exchange resin, in acid-lower aliphatic alcohol and washing in alcohol. Dried polysaccharide gel is derived as creamy to white product. Polysaccharide gel is used as dressing-patch, film-dressing, sustained-release dressing, gelling agent; used in food preparation such as jelly, medical-food products. Fiber residue after hot water extraction is treated to isolate polysaccharide fiber. The process comprises alkali hydrolysis, acid hydrolysis, decolorization and washing in dilute acid, sodium chloride and water to derive white polysaccharide fiber.
