A guaianolide alloside and other constituents from Picris kamtschatica

Phytochemistry. 2002 Dec;61(8):891-4. doi: 10.1016/s0031-9422(02)00355-2.

Abstract

From Picris kamtschatica two new guaianolide glycosides, including a beta-allopyranosyl analogue of ixerin F, were isolated, in addition to ten known sesquiterpene lactones and six phenolic compounds. This is the first time a sesquiterpene lactone alloside has been described from plants. The compounds were characterized based on mass, 1D and 2D NMR spectral data.
