The invention relates to the technical field of
medicine, and particularly discloses volatile oil for extracting
euonymus alatus flowers and a preparation method thereof.The preparation method comprises the steps of extraction and purification, according to the extraction step, 200 g of
euonymus alatus flowers are placed in 3000 ml of
ultrapure water to be soaked overnight, then heating is conducted through a constant-temperature electric jacket, and the temperature is kept at 180-200 DEG C; adding 250mL of
dichloromethane into a 500mL round-bottom flask, heating in an
oil bath, keeping the temperature at about 80 DEG C, and extracting for 8 hours by adopting a simultaneous
distillation and extraction instrument; the chemical components of the
euonymus alatus flower volatile oil are analyzed by adopting GC-MS (
Gas Chromatography-
Mass Spectrometer) in combination with retention indexes, and the volatile oil has the advantages that the chemical components of the euonymus alatus flower volatile
oil can be analyzed by adopting the GC-MS in combination with the retention indexes; and anti-inflammatory and
analgesic activity tests are carried out on the euonymus alatus by adopting a
toe inflammatory swelling experiment and a mouse twisting experiment, so that a scientific basis is provided for further development and utilization of the euonymus alatus.
