[Study on the chemical constituents from the herb of Gentianopsis paludosa].
OBJECTIVE
To study the chemical constituents from the herb of Gentianopsis paludosa.


METHODS
Column chromatogrophy and spectral analysis were used to isolate and identify the constituents.


RESULTS
Six compounds were isolated and identified as 1,7-dihydroxy-3,8-dimethoxyxanthone (I), 1-hydroxy-3, 7, 8-trimethoxyxanthone (II), 1, 8-dihydroxy-3, 7-dimethoxyxanthone (III), 1-hydroxy-3, 7-dimethoxyxanthone (IV), beta-sitosterol (V), daucosterol (VI).


CONCLUSIONS
Compounds III-VI were isolated from the plant for the first time.
