Abstract: | From the aerial parts of Phlomis rigida, three iridoid glucosides, phlorigidoside A (2-O-acetyllamiridoside), B (8-O-acetyl-6-beta-hydroxyipolamide) and C (5-deoxysesamoside), were isolated together with the known iridoid glucosides, shanzhiside methyl ester, 8-O-acetylshanzhiside methyl ester, deoxypulcheloside I, lamiridoside, and 6-beta-hydroxyipolamide. The structures of the new compounds were elucidated based on spectral and chemical evidence. |
