NOVELTY - Production of chrysanthemum leaves diosgenin comprises crushing chrysanthemum leaves, sieving, drying, and grinding; ultrasonically extracting with ethanol, filtering, and concentrating to obtain diosgenin; hydrolysis acidifying with acid, cooling, adding ammonia to neutralize pH, filtering, washing with water, vacuum-pumping, and drying to obtain inorganic ammonium salts-enriched hydrolyzate and liquid organic compound; refluxing hydrolyzate with number 120 gasoline to carry out extraction; and adding to cooling tank to crystallize, filtering, and drying.    USE - Method for production of chrysanthemum leaves diosgenin (claimed).    ADVANTAGE - The method is environment-friendly, achieves zero emission, turns waste into animal feed which completely solves waste residue treatment, and has less consumption amount of ethanol which effectively utilizes ethanol vapor waste heat and saves energy.    DETAILED DESCRIPTION - Production of chrysanthemum leaves diosgenin comprises:    (A) cleaning chrysanthemum leaves, crushing into 1-10 mm particles, sieving, drying to 105-120 degrees C until water content is 12-20%, and grinding into 80-200 mesh fine powder;    (B) adding to ultrasonic continuous countercurrent extraction machine, mixing with 75-85 wt.% ethanol/4-6 kg powder, and ultrasonically extracting to room temperature for 50-90 minutes, or extracting to 55-65 degrees C for 90-150 minutes without using ultrasonic extraction to obtain residue and extract;    (C) filtering extract through 40-100 mesh filter, and concentrating to recover ethanol and obtain diosgenin with ethanol content of less than 1% and solids content of 15-25%;    (D) hydrolysis acidifying with 0.5-0.8 mol/L acid at 120-130 degrees C for 2-3 hours, cooling to below 60 degrees C, adding 17-21 wt.% ammonia to adjust pH value to neutral, filtering, washing with water, vacuum-pumping, and drying to obtain inorganic ammonium salts-enriched hydrolyzate and liquid organic compound; and standing liquid organic compound at room temperature for 2-5 days to obtain complex organic fertilizer;    (E) refluxing hydrolyzate with number 120 gasoline to carry out extraction, controlling extraction time to obtain saturated saponin extract; and    (F) adding to cooling tank to crystallize, filtering to obtain crystalline saponin, and drying.
