Abstract

The essential oil from aerial parts of Psoralea pubescence Miq Standl Leguminoseae was analyzed by gas chromatography GC and GC/mass spectroscopy systems The major components identified were psoralen 248 bakuchiol 213 βcaryophyllene 85 germacrene D 68 and αhumulene 46 The major volatiles released by βglucosidase treatment of the aqueous plant residue were δpinene 283 germacrene D 136 and tricyclene 102 The oil showed significant antibacterial activity against Staphylococcus aureus Escherichia coli Klebsiella pneumonia and Pseudomonas aeruginosa while the βglucosidaseliberated fraction was inactiveDedicated with regards and respect to AnnaKarin BorgKarlson Professor of Organic Chemistry Royal Institute of Technology KTH Stockholm Sweden and Shosuke Yamamura Formal Professor of Natural Products Chemistry Faculty of Science and Technology Keio University Japan on the occasion of their 60th and 75th birthdaysThe generous financial support of Swedish Research LinksSida MENA Grant 34820066731 awarded to H R ElSeedi and U Göransson is greatly appreciated We are grateful for the extensive help of Dr F Ghia in identifying and collecting plant material
