ILICIFOLIOSIDES A AND B,BIS-SECOIRIDOID GLYCOSIDES FROM OSMANTHUS ILICIFOLIUS

摘要

Two new bis-secoiridoid glycosides,named ilicifoliosides A and B,were isolated from the leaves of Osmanthus ilicifolius.Their structures have been determined by 1D and 2D NMR analysis.The Oleaceae is a family of medium size with 25 genera and about 600 species,and this family is a rich source of iridoid,secoiridoid,phenylpropanoid and lignan glycosides.
