Chromatographic separation of the MeOH extract from the aerial parts of Saussurea pulchella led to the isolation of seven terpenes (1-4, 11-13), and eight phenolics (5-10, 14-15). Their structures were determined by spectroscopic means to be (3S)-3-O-(3',4'-diangeloyl-beta-D-glucopyranosyloxy)-3,7-trimethylocta-1,6-diene (1), 7delta-methoxy- 4(14)- oppositen-1beta-ol (2) 4(15)- eudesmene-1beta,...
Four non-host plant extracts from Bifora radians, Arctium lappa, Humulus lupulus and Xanthium strumarium, were tested against adult grape berry moths, Paralobesia viteana, for their potential as repellents or oviposition deterrents. Responses were compared with those elicited by the major component of the P. viteana sex pheromone. Moths of both sexes exhibited varying electroantennogram (EAG) r...

However, little research has been reported on the preparative separation of these compounds from burdock roots. In the present study, a combinative method of HSCCC and semi-preparative HPLC was developed for the semi-preparative separa...
