[A new phenylethanoid glucoside from Lagotis brevituba].
OBJECTIVE
To study the chemical constituents of Lagotis brevituba.


METHODS
The chemical constituents were isolated and purified by silica gel column chromatography, polyamide column chromatography, and semi-preparative HPLC, and their structures were elucidated on the basis of analysis of IR,NMR, 2D-NMR, and MS spectra.


RESULTS
Two compounds were obtained and were identified as phenylethanoid glucosides, lagotiside A (1) and acteoside (2), respectively.


CONCLUSIONS
Compound 1 is a new compound and named as lagotiside A.
