specific Embodiment approach 1
[0014] Specific embodiment 1: In this embodiment, siruphin is extracted according to the following steps: (1) Grinding the washed Liaogewang into particles with a particle size of less than 10 meshes, and then putting it into a granule with a temperature of 85 to 100°C and a concentration of 50% to 50%. 85% ethanol was extracted 2 to 3 times, and the extraction time was 2 to 4 hours each time, and filtered under the condition that the temperature of the extract was 85 to 90°C; Concentrate to a solid phase under the condition of ℃; (3) The concentrated solid phase is extracted by petroleum ether, chloroform, and ethyl acetate in sequence, and each solvent is extracted 3 to 4 times respectively; (4) Combine the ethyl acetate extracts Carry out drying, then separate the dried extract through silica gel column chromatography twice, and use the chloroform-methanol liquid gradient elution with volume ratio of 100~80:0~20; , and dried under the condition of 40-60° C. to form a solid ...
specific Embodiment approach 2
[0019] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the Liaogewang granules pulverized in step (1) is put into temperature and is 90~95 ℃, concentration is the ethanol extraction of 60%~80% 3 times , each extraction time is 3h. Other steps and parameters are the same as those in Embodiment 1.
specific Embodiment approach 3
[0020] Specific embodiment three: the difference between this embodiment and specific embodiment one is: the Liaogewang granule pulverized in step (1) is put into temperature and is 95 ℃, concentration is the ethanol extraction of 65%~70%. Other steps and parameters are the same as those in Embodiment 1.
