The chemical composition of EOs
The chemical composition of the EOs isolated from two plants growing in Egypt obtained by hydro-distillation was analyzed using GC/MS (Table 1). The results of the analyses showed that the oil of A. herba-alba was rich in camphor (27.65%), chrysanthenone (16.48%), 1,8-cineole (8.90%), and α-thujone (7.85%), followed by camphene (4.10%) and sabinene (4.02%), while the major component of L. nobilis was 1,8-cineole (49.74%), followed by sabinene (12.38%) and α-terpinyl acetate (10.20%).
