摘要：Survey and evaluation of wild plants that grow in Egyptian desert are of the priorities of thecurrent study, so this present survey was carried out to examine the composition andantimicrobial activity of Francoeuria crispa (Forssk) plant growing wild in eastern Egyptiandesert. Francoeuria crispa is an annual herb or sometimes a perennial subshrub producing smallbright yellow flowers. The plant materials were collected from the plants growing on easterndesert approximately 1200 km out of Cairo. The chemical composition of the volatile oil,isolated by hydrodistillation of the herb, was investigated by GC and GC-MS. The percentage ofessential oil of F. crispa (Forssk.), obtained in 0.23% v/w on a dry weight basis, consistedapproximately of piperitone 45.0 %. Other oxygenated monoterpene compounds were found;the principal members were, cis-sabinene hydrate, (0.35%) linalool (0.85%) terpineol(1.08%), neral (0.80%)), linalyl acetate (0.47%) and, anethole trans (1.0%). Oxygenatedmonoterpene (OMG) group gave the highest percentage (50.85%) against 6.69, 4.8 and 27.77%for monoterpene hydrocarbon group (MHG), sesquterpenes hydrocarbon group (SHG) andoxygenated sesquterpenes group (OSG) respectively. The results proved that, F. crispa is rich incarbohydrates or glycoside, sterols and flavonoids. Tannins and coumarins are found inmoderate amounts, while, alkaloids, saponins and anthraquinones are absent. The antimicrobialactivities of the water and alcohol extracts of F. crispa herb were carried out using the invertedPetri plate method. The water and alcohol extraction showed prominent antimicrobial activitiesagainst fungi, gram positive and gram negative bacteria at a very low concentration (10 l).
