Plant material was collected from wild plant populations of Triumfetta flavescens (Hochst) grown in sandy soils in western desert region, Egypt. Triumfetta flavescens (Hochst) herb contains high amounts of flavonoids and tannins. The yield of volatile oil (VO) obtained by hydro -distillation from aerial parts of Triumfetta flavescens (Hochst) ranged from 0.5 to 0.9%. The major constituents of Triumfetta flavescens (Hochst) VO were eudesmol (19.9%), caryophyllene oxide (9.1%), alpha-caryophyllene (5.8%) and pentadecanol (4.7%). The majority of these components were found to belong to the oxygenated sesquiterpenes hydrocarbons class (SCHO), with percentage of 44.5%. Triumfetta flavescens (Hochst) extract showed activities against gram positive bacteria, while it was inactive against gram negative bacteria, fungi and yeast. (c) All Rights Reserved
