Studies on Stachys sieboldii MIQ. I. Isolation and Structures of New Glycosides

Abstract

A new iridoid glycoside, stachysoside A (2) and two new phenylethanoid glycosides, stachysosides B (3) and C (5) have been isolated from the tuber of Stachys sieboldii MIQ. (Labiatae), together with six known glycosides. The structures of new compounds were established on the basis of chemical evidence and spectral data.
