A new furolactone-type lignan from Lycium chinense.
The phytochemical investigation of extracts from the root barks of Lycium chinense yielded a new furolactone-type lignan, lyciumin (1). Its structure and absolute configurations were established on the basis of spectral data, particularly by the use of 1D NMR, 2D shift-correlated NMR pulse sequences ((1)H-(1)H COSY, HSQC, HMBC and ROESY) and CD spectra.
