Four new phenolic glycosides from Baoyuan decoction

Four new phenolic glycosides, including two flavonoid glycosides (1 and 2) and two lignan glycosides (3 and 4), were isolated from the traditional Chinese medicine formula, Baoyuan decoction. Their absolute configurations were determined by experimental electronic circular dichroism data and chemical methods, and their sources were analyzed by the UPLC-Qtrap-MS method.234
