摘要：

Two new ecdysteroid acetonide derivatives, 5 alpha-2-deoxy-20-hydroxyecdysone 20,22-acetonide (6) and makisterone C 2,3;20,22-diacetonide (8), were isolated from the dried herb of Silene viridiflora. The already known 5 beta-2-deoxy-20-hydroxyecdysone 20,22-acetonide (7) is additionally reported here as a new constituent of S. viridiflora. Five earlier described S. viridiflora ecdysteroids, integristerone A (1), 5,20,26-trihydroxyecdysone (26-hydroxypolipodine B;2), 20,26-dihydroxyecdysone (3), 2-deoxy-20-hydroxyecdysone (4), 2-deoxyintegristerone A (5), are also included because of their improved characterization. The structures were established via spectroscopic analyses, including one- and two-dimensional NMR and mass spectrometry.
