Embodiment 1-1
[0019] A method for preparing effective fractions of Waxburgh chinensis, the method sequentially includes the following steps:
[0020] Step (1) Sorting and drying the waxberry leaves, soaking them in water for 30 minutes, steam distillation to extract the volatile oil, collecting the volatile oil, drying it with anhydrous sodium sulfate, and using it as the effective part of the volatile oil;
[0021] Step (2) The distilled aqueous solution is stored in another device; the dregs are extracted with a solvent, filtered, and the extract is collected, combined with the distilled aqueous solution, concentrated under reduced pressure, and the concentrated solution is adsorbed on a macroporous resin chromatography column, and the column is doubled. Elute with volume water, discard the water washing solution, continue to elute with 10% ethanol of 2 times the column volume, discard the eluent, continue to elute with 30% ethanol for 2 times the column volume, collect the eluent, and dep...
Embodiment 1-2
[0024] A method for preparing effective fractions of Waxburgh chinensis, the method sequentially includes the following steps:
[0025] Step (1) Sorting and drying the waxberry leaves, soaking them in water for 60 minutes, steam distillation to extract the volatile oil, collecting the volatile oil, drying with anhydrous sodium sulfate, and using it as the effective part of the volatile oil;
[0026] Step (2) The distilled aqueous solution is stored in another device; the dregs are extracted with a solvent, filtered, and the extract is collected, combined with the distilled aqueous solution, concentrated under reduced pressure, and the concentrated solution is adsorbed on a macroporous resin chromatography column, and the condensed solution is absorbed by a 6-fold column Elute with volume water, discard the water washing solution, continue to elute with 30% ethanol of 6 times the column volume, discard the washing solution, continue to elute with 90% ethanol of 6 times the colum...
Embodiment 1-3
[0029] A method for preparing effective fractions of Waxburgh chinensis, the method sequentially includes the following steps:
[0030] Step (1) Sorting and drying the waxberry leaves, soaking in water for 45 minutes, steam distillation to extract the volatile oil, collecting the volatile oil, drying with anhydrous sodium sulfate, and using it as the effective part of the volatile oil;
[0031] Step (2) The distilled aqueous solution is stored in another device; the dregs are extracted with a solvent, filtered, and the extract is collected, combined with the distilled aqueous solution, concentrated under reduced pressure, and the concentrated solution is adsorbed on a macroporous resin chromatography column, and the chromatographic column is used for three times. Elute with volume water, discard the water washing solution, continue to elute with 3 times column volume of 60% ethanol, discard the eluent, continue to use 3 times column volume for elution with 60% ethanol, collect ...
