New maltol glycosides from Flos Sophorae

Abstract Three new maltol glycosides, designated soyamalosides A (1), B (2), and C (3), together with eight known compounds (4–11), were obtained from a 70 % EtOH extract of Flos Sophorae. Their structures were elucidated by chemical and spectroscopic methods. Of the known compounds, this is the first report of 4–6, 9, and 11 in the Sophora genus. Compounds 2, 3, and 10 showed significant protective effects against antimycin A-induced L6 cell injury.
