Ij. Chen et al., EFFECTS OF XANTHONE GLYCOSIDE ON EPHEDRINE-INDUCED BITING BEHAVIOR AND MOTOR-ACTIVITY, The American journal of Chinese medicine, 21(1), 1993, pp. 79-84
1-Hydroxy-3,4,7,8-tetramethoxyxanthone, beta-sitosterol, uvaol-3-palmi
tate, and sweroside have been isolated from the fresh whole plant of T
ripterospermum lanceolatum (Hayata) Haraex Satake (Gentianaceae). Our
results on the pharmacological studies of xanthone glycoside and lance
oside suggested that they have a CNS depressant effect.
