OBJECTIVE

To study the chemical constituents of Lagotis yunnanensis W. W. Smith.

METHODS

Compounds were isolated from the ethanolic extract of the title herb by silica gel column chromatography, and their structures were identified by physical and chemical evidences and spectral methods.

RESULTS

Seven compounds were isolated and identified as artselaeroside A (1),3-hydroxy-5-methoxy-benzyl alcohol (2), tyrosol (3), glycerin-9'-Z-octadecaenate (4), glycerin-docosanate (5), glycerin-tetracosanate (6), tetracosanoic acid (7), respectively.

CONCLUSIONS

All the compounds were isolated from this plant for the first time.
