Embodiment 1
[0020] (1) Preparation of test solution
[0021] Take Fuqing Snow Lotus Suppository as raw material, take 10 capsules of Fuqing Snow Lotus Suppository, heat and melt in a water bath at 60°C, and let cool. Take about 1.5g, cut it into pieces, weigh it accurately, put it in a stoppered Erlenmeyer flask, add 15ml, 15ml, and 15ml of methanol respectively, ultrasonicate (power 360W, frequency 35kHz) 3 times, each time for 20 minutes, filter, and combine Put the filtrate in a 50ml measuring bottle, add methanol to the mark, shake well, and it is the test solution;
[0022] (2) Content determination of scopoletin, umbelliferone and osthole
[0023] The experimental conditions of high performance liquid chromatography are as follows: C 18 Chromatographic column: 250mm×4.6mm, 5μm; mobile phase: acetonitrile as mobile phase A, water as mobile phase B; elution gradient: 0-17min: 10%-60%A; 17-18min: 60%-80 %A; 18-24min: 80%A; 24-30min: 80%-95%A; 30-32min: 95%-10%A; 32-42min: 10%A.
