Abstract:
PROBLEM TO BE SOLVED: To prevent or ameliorate cancer by compounding daily takable food with a composition with anticancer activity containing ingredients extracted from Cordyceps and/or its mycelia-cultured solution, or by compounding drugs with such a composition containing the ingredients.SOLUTION: Cordyceps and/or its mycelia-cultured solution is subjected to, according as needed, hot water extraction; subsequently, the Cordyceps and/or its mycelia-cultured solution, or a solution obtained by subjecting the Cordyceps and/or its mycelia-cultured solution to hot-water extraction, is subjected to hydrous alcohol extraction; subsequently, the resulting solution obtained by the hydrous alcohol extraction is subjected to reverse-phase column chromatography under predetermined conditions to make a crude fractionation to obtain fractions. Thereafter, a composition with anticancer activity containing ingredients contained in fractions with retention times of 4.4-5.5 min (fractions F2 to 4) among the fractions, is obtained. Using the composition, cancer can be prevented or ameliorated.
Abstract:
PROBLEM TO BE SOLVED: To modify an animal protein-based raw material, a semi-product and a product so as to exhibit a high property of heat generation of wetting. SOLUTION: This method for modifying an animal protein-based raw material such as a modified wool, silk, leather, animal hairs, etc., is provided by bathing such raw materials in a treating liquid containing 1-30 wt. % unsaturated basic organic acid based on the above materials, setting bath ratio at (1:5-30) and adding a catalyst, in 100-130°C temperature range and for 1-3 hr.
