Embodiment 1

[0032] This example proposes a euphorane triterpenoid compound extracted from Tripterygium wilfordii, which is a white crystal with a molecular weight of 456 and a molecular formula of C 30 h 48 o 3 , the specific structural formula is as follows:

[0033]

[0034] The compound is isolated and purified from the dried root of Tripterygium wilfordii, and the specific extraction steps are as follows:

[0035] 1) Take 14.0kg of dried root of Tripterygium wilfordii as raw material, grind it with 95% ethanol aqueous solution which is 6 times its weight, and extract it under reflux for 3 times, then concentrate under reduced pressure until it is free of alcohol to obtain 650g of extract.

[0036] 2) Dissolve the extract with a mixed solvent of chloroform and methanol (1:1), mix the sample with 2 times the amount of silica gel (1300g) after dissolving, separate with 4 times the amount of silica gel (2600g), and use petroleum ether / acetone in turn The solvent (20:1, 10:1, 6:1, 4:...
