Objective:
To investigate the chemical constituents of Saussurea laniceps.
Method:
The ethanol extract of S. laniceps was separated by means of silica gel chromatography. The compounds isolated from the plant were identified by their spectral evidence.
Result:
Fifteen compounds were isolated and identified as beta-stiosterol (1), umbelliferone (2), 4-hydroxyacetophenone (3), scopoletin (4), isoscopoletin (5), xuelianlactone (6), methyl 3-(2', 4'-dihydroxyphenyl) propanoate (7), apigenin (8), neoechinulin A (9), daucosterol (10), scopolin (11), xuelianlactone 8-O-beta-D-glcuoside (12), apigenin 7-glcuoside (13), apigenin 7-lutinoside (14) and syringin (15).
Conclusion:
Compounds 5-15 were isolated from S. laniceps, and among them, 7 and 9 were isolated from genus Saussurea for the first time.
