[0029] 2. Content determination
[0030] (1) Chromatographic conditions and system applicability experiment: Octadecylsilane bonded silica gel was used as filler, methanol-water (65:29) solution was used as mobile phase, the detection wavelength was 225nm, and the number of theoretical plates was based on that of woody hydrocarbon. Ester peak calculation is not less than 3000;
[0031] (2) Same as Example 1.
[0032] (3) Preparation of the test solution: Grind the content of the product under the difference in loading amount, mix it evenly, take 0.6g, accurately weigh it, put it in a stoppered Erlenmeyer flask, and accurately add 20% of chloroform ml, plugged, weighed, shake well, leave overnight, ultrasonic treatment (250W, 50Hz) for 20 minutes, take out, let cool, weigh again, make up the lost weight with chloroform, shake well, filter , take 10ml of the continued filtrate, place it in an evaporating dish, evaporate it to dryness, add methanol to dissolve the residue and t...

[0035] 2. Content determination
[0036](1) Chromatographic conditions and system suitability experiment: Octadecylsilane bonded silica gel was used as filler, methanol-water (71:35) solution was used as mobile phase, the detection wavelength was 225nm, and the number of theoretical plates was based on the number of woody hydrocarbons. Ester peak calculation is not less than 3000;
[0037] (2) Same as Example 1.
[0038] (3) Preparation of the test solution: Grind the content of the product under the item of difference in loading, mix well, take 0.6g, accurately weigh it, put it in a stoppered Erlenmeyer flask, and accurately add 30ml of chloroform , Sealed, weighed, shake well, leave overnight, ultrasonic treatment (250W, 50Hz) for 40 minutes, take out, let cool, weigh again, make up for lost weight with chloroform, shake well, filter, Take 10ml of the filtrate and place it in an evaporating dish, evaporate it to dryness, add methanol to dissolve the residue and transfer it...
