Title:
PRODUCTION OF NEW LIGNAN GLYCOSIDE
Document Type and Number:
Japanese Patent JP2988656
Kind Code:
B2
Abstract:
PURPOSE: To produce a new lignan glycoside useful as foods, medicines, cosmetics, agrochemicals, etc., by carrying out the humidifying treatment, etc., of a sesame seed, then extracting a pulverized substance, etc., of the treated seed with a lower alcohol, etc., and removing a fat-soluble and a water-soluble substances from the resultant extract.
CONSTITUTION: The humidification or germination treatment of a sesame seed is carried out to increase a new lignan glycoside of the formula ]R denotes one glycosyl residue such as glucose, galactose and fructose, etc.; (m) denotes an integer of 1-3; (n) denotes an integral value of 0 or 1] in the resultant treated substance and a pulverized substance or a defatted meal thereof is then extracted with a lower alcohol (e.g. methanol) or a hydrous lower alcohol. The obtained extract is further treated with a saccharide chain hydrolase (e.g. a α-glucosidase) in an aqueous solution and a fat-soluble and a water-soluble substances are then removed from the enzymically treated substance. The prepared unhydrolyzed substance is subsequently concentrated to afford the new lignan glycoside, widely utilized in the fields of foods, medicines, cosmetics, agrochemicals, etc., and represented by the formula.
