Abstract

To study the chemical constituents of Pharbitis purpurea.The constituents were isolated by silica gel column chromatography, HPLC and recrystallization and their structures were elucidated on the basis of spectral analysis.Fourteen compounds were isolated and identified as daucosterol (1), umbelliferone (2), ursolic acid (3), N-p-hydroxy-cis-coumaroyltyramine (4), N-p-hydroxy-trans-coumaroyltyramine (5), N-cis-feruloyltyramine (6), N-trans-feruloyltyramine (7), (3R, 5R, 6S, 7E, 9S)-megastigman-5,6-epoxy-7-ene-3,9-diol (8), (6S,9R)-vomifoliol (9), (+)-syringaresinol (10), isovitexin (11), syringopicroside( 12), uricil (13), (6S,9R)-roseoside (14).Compounds 3, 8-2,14 are isolated from the genus for the first time.
