NOVELTY - Extracting Lycoris radiata galantamine comprises: (i) determining chromatographic conditions by setting a Kromasil 100-5-C18 reverse phase column, providing acetonitrile-phosphate buffer as mobile phase; (ii) preparing standard curve by preparing mixed standard solution having a concentration of e.g. 0.005 mg/ml, then passing via microporous membrane filter; and (iii) extracting Lycoris radiata powder by adding cellulase and pectinase at pH 4.5, centrifuging, collecting the supernatant and calculating galantamine yield using chromatographic test.    USE - The method is useful for extracting Lycoris radiata galantamine (claimed).    ADVANTAGE - The method is simple, economical and does not cause environmental pollution.    DETAILED DESCRIPTION - Extracting Lycoris radiata galantamine comprises: (i) determining chromatographic conditions by setting a Kromasil 100-5-C18 reverse phase column (250 mmx 4.6 mm, 5 mu m), providing acetonitrile-phosphate buffer (17:83) as mobile phase, setting column temperature to 35 degrees C, injection volume to 20 mu l and detection wave length to 290 nm, where the phosphate buffer is prepared by dissolving 2.72 g potassium dihydrogen phosphate in 100 ml water, adding 1.4 ml triethylamine solution, making up volume to 1 l with water and regulating pH to 7.02; (ii) preparing standard curve by weighing 25 mg galantamine and 25 mg lycorine standard product, mixing 1 mg/ml galantamine with 1 mg/ml lycorine standard product, preparing 0.05 ml, 0.1 ml, 0.2 ml, 0.5 ml, 1 ml, 2 ml and 5 ml galantamine and lycorine standard solutions in 10 ml volumetric flask to prepare mixed standard solution having a concentration of 0.005 mg/ml, 0,01 mg/ml, 0.02 mg/ml, 0.05 mg/ml, 0.1 mg/ml, 0.2 mg/ml and 0.5 mg/ml, passing via 45 mu m microporous membrane filter according to above chromatographic conditions to obtain regression equation; and (iii) extracting 2 g Lycoris radiata powder by adding cellulase and pectinase under certain temperature for certain time at pH 4.5, centrifuging the resultant aqueous solution at 5000 rotations/minute for 20 minutes, collecting the supernatant and calculating galantamine yield using chromatographic test.
