GC/MS chromatogram of the 4 tetrahydrofuran studied H. perforatum genotypes (HP) revealed that the main constituents for HP1 were: 9-Octadecenamide (Z)-(Oleic acid) (65.551%), Hexadecenamide (20.681%) and Dodecenamide (5.595%). Whereas, for HP2, they were 9-Octadecenamide (Z)- (Oleic acid) (63.117%), Hexadecenamide (19.107%) and Dodecenamide (5.585%). As for HP3, they were 9-Octadecenamide (Z)-(Oleic acid) (63.496%), Hexadecenamide (18.891%) and Dodecenamide (5.961%). Whereas, they were 9-Octadecenamide (Z)-(Oleic acid) (62.048%), Hexadecenamide (19.325%) and Dodecenamide (5.914%) for HP4. Thereby, isolation of these constituents and investigation of their biological activity is requested. ER -
