    摘要: Provided is a novel polysaccharide derivative having a main structure of the following formula (1) in which a polysaccharide or its derivative has been chemically bonded to the inner and outer surfaces of the pores of a porous carrier at the reducing terminal of the polysaccharide or polysaccharide derivative: ##STR1## Also provided are a method of producing the novel polysaccharide derivative in which a silane agent is chemically bonded to a porous carrier and thereafter a polysaccharide having a degree of polymerization from 11 to 500 or its derivative is further chemically bonded to surface treated carrier at the reducing terminal of the polysaccharide or its derivative, and a method of producing the novel polysaccharide derivative in which a polysaccharide having a degree of polymerization from 11 to 500 or its derivative is chemically bonded to a silane agent at the reducing terminal of the polysaccharide or its derivative and thereafter the polysaccharide derivative is further chemically bonded to a porous carrier. Further provided is a separating agent for chromatography containing the novel polysaccharide derivative. The novel polysaccharide derivative has excellent solvent resistance and is useful as a separating agent for chiral resolution of chiral compounds by chromatography. The methods of the present invention efficiently give the novel polysaccharide derivative.

    摘要: A variety of plant diseases and damage by certain pests in agricultural and horticultural plants can be efficiently controlled without substantial chemical injuries by applying a plant-protecting composition which comprises (a) 1 part by weight of a chitosan hydrolyzate having an average molecular weight of 10,000 to 50,000, obtained by acid hydrolysis or enzymatic hydrolysis of chitosan and (b) 0.25 to 4 parts by weight of acetic acid. Any possible chemical injury to plants caused by applying the composition can be further reduced when the composition is admixed with a deproteinized juice of alfalfa leaves.

    摘要: A process for producing starch noodles, which comprises adding 45-55 parts by weight of hot water to 100 parts by weight of starch obtained from at least one member-selected from the group consisting of potato, sweet potato, tapioca, corn, wheat and a product thereof followed by being mixed to prepare large particles of dough and then extruding the dough under degassing at degrees of vacuum of not less than 650 Torr to produce a dough sheet. Starch noodles can be produced efficiently in simple procedures without separately preparing starch paste and without using special rollers. Further, starch noodles thus produced are highly transparent and less melted by boiling.
