Abstract
A new family of four phytoecdysteroids have been isolated from aerial part of Ajuga reptans var. atropurpurea harvested at the beginning of autumn. These compounds show a novel 22-oxo-12 beta-hydroxy functional ization of the C-28 and C-29 gamma-lactonic ecdysteroids. The structur e of those compounds was inferred from the corresponding IR, H-1 and C -13-NMR and HPLC-MS(TSP) spectral data.
