[0022] The following examples will further illustrate the method provided by the invention.
[0023] Implementation example
[0024] (1) Put 2000 grams of 100-300-mesh silica gel in a beaker, add about 1500 mL of petroleum ether, and wet-pack it into a chromatographic column with a column diameter ratio of 5:1-10:1.
[0025] (2) Add 200mL of Jatropha crude oil to the top of the chromatographic column, elute with petroleum ether: ethyl acetate = 75:1, control the flow rate at about 4.5mL / min, and collect the bright yellow and yellow-green effluent Until an orange-yellow effluent appears (collect the effluent with a volume ranging from 100 mL to 1000 mL), and concentrate under reduced pressure at 30°C until there is no mobile phase to obtain about 2 mL of an oily primary fraction. Repeated separation and purification by this method to obtain about 20mL oily primary fraction.
[0026] (3) Put 1200 grams of 200-400 mesh silica gel in a beaker, add about 1000 mL of petroleum ethe...
