Zusammenfassung
From the aerial parts of A. salicifolia (L.) Schreber, a new ionone glycoside (3beta -hydroxy-7,8-dihydro-4-oxo-beta -ionol-9-O-beta -D-glucopyranoside) (I) was isolated, along with the known compds. corchoionoside C, 8-O-acetylmioporoside, ajugol, harpagide, 8-O-acetyl-harpagide, lavandulifolioside, and leonosides A and B. This is the 1st report of the occurrence of ionone glycosides and ...

This is the 1st report of the occurrence of ionone glycosides and 8-O-acetylmioporoside in Ajuga spp. Ajugol, lavandulifolioside, and leonosides A and B were isolated for the 1st time from A. salicifolia. The structures were elucidated by means of 1D-, 2D-NMR spectroscopy, and HR-MALDI mass spectrometry.
