NOVELTY - Method for extracting saponin from Camellia, involves (a) pressing and drying Camellia, and purifying Camellia which is the raw material, (b) crushing dried Camellia, (c) performing magnetic separation, (d) screening and removing impurities from the crushed Camellia, (e) immersing the crushed Camellia in purified water, (f) performing separation, (g) processing filtrate, and heating and flocculating the filtrate, (h) again performing separation, (i) performing extraction, and (j) concentrating extract.    USE - The method is useful for extracting saponin from Camellia (claimed). The saponin is used in pollution-free detergents, industrial emulsifier, pollution-free pesticide, foaming agent and in food industry.    ADVANTAGE - The method extracts saponin having high quality and purity of greater than or equal to 95%, improves economic benefit thus alleviates poverty of people, and promotes sustainable development, and productivity of Camellia.    DETAILED DESCRIPTION - Method for extracting saponin from Camellia, involves (a) pressing and drying Camellia to obtain Camellia oil, and purifying Camellia which is the raw material, (b) crushing dried Camellia, (c) subjecting crushed Camellia to magnetic separation for removing metal impurities, (d) screening and removing impurities from the crushed Camellia to obtain crushed Camellia with high purity and quality, (e) immersing the crushed Camellia in purified water, and simultaneously stirring and heating immersed Camellia at 30-35 degrees C, where the ratio of crushed Camellia in purified water is 1:5, and the crushed Camellia is immersed in purified water for 2-4 hours, (f) subjecting immersed Camellia to separation, filtering obtained product to obtain filtrate, coarse residue and fine residue, and drying the fine residue which is used as fertilizer or fuel, (g) processing filtrate, and heating and flocculating the filtrate, (h) again subjecting the flocculate to separation, and filtering obtained product to obtain filtrate and filter residue, (i) performing extraction, and (j) concentrating extract by vacuum heating and dehydration process to obtain product comprising activated saponin, and drying the product to obtain powdered saponin.
