New maltol glycosides from Flos Sophorae.
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.
