Lignan and terpene glycosides from Epimedium sagittatum

From the aerial parts of Epimedium sagittatum, four new lignans, icarisides E6, E7, icariols A1, A2, a new phenylethanoid, icariside D3, a new phenylpropanoid, icariside H1 and a new ionone derivative, icariside B9, have been isolated together with 20 known compounds. The structures of new compounds were established by spectral and chemical evidence.
