Abstract

Three compounds, pubadysone [11 alpha -hydroxy-18,20-oxido-3-oxo-pregna-1,4,17(20)-triene] (1), puboestrene [3-acetoxy-17-oxo1,3,5(10)-estratriene] (2) and pubamide [3,18-dioxo-11 alpha -hydroxycona-1,4-diene] (3), have been isolated from the bark of Holar-rhena pubescens. Their structures have been established through spectroscopic studies. (C) 2001 Elsevier Science Ltd. All rights reserved.
