Embodiment Construction
[0016] refer to figure 1 , figure 2 , the extraction method of anti-inflammation component of copper drill of the present invention is that 20 kg of dried stems of copper drill are cut into small sections, soaked in 95% ethanol with volume fraction for 3 h, heated and refluxed for 3 times, the first time for 3 h , the second time and the third time each 2h, the extract was concentrated under reduced pressure to obtain 1.2 kg of extract. The extract was dissolved in 5% tartaric acid, and filtered to obtain 460 g of acid-water insoluble matter. 460g of the water-insoluble acid was dissolved in water and extracted with ethyl acetate. The ethyl acetate extraction fraction (110 g) was separated by silica gel column chromatography, and gradient eluted with dichloromethane and methanol solvent system (volume ratio of 100:0 to 0:100) to obtain Fr.E1 (3.2 g), Fr. E2 (1.4 g), Fr. E3 (25.0 g), Fr. E4 (40.0 g), Fr. E5 (21.1 g), Fr. E6 (10.5 g) and Fr. E7 (1.3 g) a total of 7 parts. ...
