Background: From the bioactivity stand point Artemisia monosperma Del. is reputed to have antispasmodic and anthelmintic properties. Various types of secondary metabolites were reported in A. monosperma plants from different localities. Objective: The current study was planned aiming to investigate the influence of stage of development on the composition, antimicrobial, antiinflammatory and antioxidant activities of the essential oil derived from the aerial parts of the Libyan plants. Material and Methods: A. monosperma volatiles were hydro-distilled from aerial parts of Libyan plants, collected at different stages of growth: before flowering (A1), and at beginning (A2) and by the end (A3) of flowering stage. Yields ranged from 0.16-0.26 ml/100g fresh material (A3, highest). GC/FID and GC/MS analyses were performed. Results: Among 16-20 identified components (97.63-99.00\% of total composition), 11 were common in all samples. A1 and A2 showed close amounts of hydrocarbons (63.56 and 66.55\%), but lesser than A3 (88.36\%); monoterpenoids were mainly represented by sabinene (13.15-22.85\%), \β-pinene (9.00-24.03\%) and \β-cis-ocimene (3.73-12.92\%); while sesquiterpenoids appeared absent. Among oxygenated components (11.29, 31.08 and 35.44 \% in A3, A2 and A1), bornyl acetate was the major monoterpenoid (8.00-31.00\%, highest in A1); and the sesquiterpenoid, \β-eudesmol (8.01\%) was detected in A2 only. Moreover, A2 demonstrated significant antifungal effect against Aspergillus fumigatus and Geotricum candidum (MIC 0.98 and 0.24 \μg/ml). Conclusion: A3 exerted the highest anti-inflammatory activity as compared to the other volatiles. A1 restored the reduced blood GHS level in diabetic animals almost as efficiently as Vitamin E. The antioxidant activity of the volatiles is decreased during the flowering stage, being the highest before flowering (A1); this could be associated to the decreasing bornyl acetate content of the samples.

Background: Haplophyllum tuberculatum is a plant belongs to family rutacee. It is rich in volatile oils, fixed oils, alkaloids, and furanocoumarins. It is well known for the huge number of folkloric uses in middle east. \ Objective: The aim of this study is to establish the chemical composition of the essential oils of Libyan H. tuberculatum and to investigate their cytotoxic potentialities. Materials and Methods: The essential oils of the aerial parts and flowers of H. tuberculatum growing in Libya were prepared by hydrodistillation. GC/MS analyses were performed on a Shimaduz capillary gas chromatograph (GC 17A ver.3) instrument directly coupled to mass spectrometer-MS QP5050A. Oil A and F of H. tuberculatum at different concentrations (0-50 \µg/ml) in DMSO were tested for cytotoxicity against human tumor cell lines. Results: Oil yield was found 0.4 and 1.5 (v/w \%) on dry weight basis respectively. GC/MS analysis resulted in identification of total 35 compounds. 15 compounds\  were common to both oils. oil A of H. tuberculatum exhibited antitumor activities against. liver carcinoma cell line (HEPG2) and lung carcinoma cell line (H1299) 4.7 \µg/ml and 4.1 \µg/ml. Conclusion: Essential oil of the aerial parts of H. tuberculatum is potentially active against lung (H-1299), and liver (HEPG2) carcinoma cell lines. The observed cytotoxic, activities can be attributed to the dominance of \α and \γ-terpinene in this oil.
