Abstract

Abstract magnified image Two new ecdysteroid acetonide derivatives, 5 α ‐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 β ‐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.
