[0038] The preparation method of the tetracyclic diterpenoids of the present invention is to use the root of Angelica sinensis as a raw material, and obtain through extraction from extract, organic solvent extraction, silica gel column chromatography, and high-pressure liquid chromatography, specifically:
[0039] A, extraction of extract: dry and pulverize the roots of Angelica sinensis to obtain 0.05 ~ 0.15cm particle size, add 80 ~ 95% ethanol solution with a volume percentage concentration of 4 ~ 8 times of root weight ratio of Angelica sinensis in Reflux extraction at 65~74°C for 3~5 times, each time for 1~3h, combine the extracts, filter the extracts, concentrate the extracts under reduced pressure until the specific gravity is 1.1~1.3 to obtain the extract a;
[0040] B, organic solvent extraction: add the water of 2~4 times of weight ratio in extract a, carry out extraction with sherwood oil, ethyl acetate and n-butanol solvent of equal volume to water successively, eve...
