1-Hydroxy-3,4,7,8-tetramethoxyxanthone, beta-sitosterol, uvaol-3-palmitate, and sweroside have been isolated from the fresh whole plant of Tripterospermum lanceolatum (Hayata) Haraex Satake (Gentianaceae). Our results on the pharmacological studies of xanthone glycoside and lanceoside suggested that they have a CNS depressant effect.
