Abstract

This study was investigated by analyzing the potent bioactive compounds in the chloroform extract of Porteiria hornemanii using gas chromatography–mass spectrometry (GC-MS) analysis. The crude 50 µg/ml of white crystalline solid were tested in vitro for their antibacterial effect against Xanthomonas axonopodis pv. citri and Xanthomonas axonopodis pv. malvacearum using paper disc diffusion technique showing 10.00 mm  and 12.00 zone inhibition respectively, whereas streptomycin sulphate showed 15.00 mm zone and inhibition. The white crystalline solid mainly contained 1,2–Benzenedicarboxylic acid, diisoctyl ester (C24 H38 O4) (48.21%) and 1,2–Benzenedicarboxylic acid, bis (2-methylpropyl) ester (C6 H22 O4) (19.67%).

 

Key words: Gas chromatography–mass spectrometry (GC-MS), Porteiria hornemanii, white crystalline solid, seaweeds.
