Chemical Composition and Antimicrobial Activity of Essential Oils ofJasonia candicansandJ. montana

Abstract

The essential oils of the aerial parts of Jasonia candicans and J. montana were analyzed by gas chromatography-mass spectrometry (GC/MS) technique. Of twenty-one components identified in the volatile oil of J. candicans, intermediol was the main constituent. Fifty-eight components were characterized in the essential oil of J. montana. Camphor, borneol, bornyl acetate, chrysanthemol, intermediol, and 1,8-cineole were the major constituents in this oil. The two oils showed antibacterial activity against Bacillus subtilis. They also showed a marked antifungal activity against Trichophyton mentagrophytes, Cryptococcus neoformans, and Candida albicans.

Screening Chemical Composition and in Vitro Antioxidant and Antimicrobial Activities of the Essential Oils from Origanum syriacum L. Growing in Turkey

“…Specific gravity of the oil was 0.90 g/cm 3 at 25°C. Chromatographic Analysis Qualification of the essential oil was analyzed on an MSD 5971A mass spectrometer coupled with a Hewlett-Packard GC-5890II series GC.…”

“…The antimicrobial and antioxidant properties of essential oils have been known for a long time, and a number of investigations have been conducted on their antimicrobial activities using various bacteria, viruses and fungi. [1][2][3][4][5][6] Free radicals, e.g., superoxide ions (O 2 · Ϫ ), hydroxyl radicals (OH · ) and non-free radical compounds, can be responsible for lipid peroxidation (deterioration) in foods [7][8][9] and for various diseases such as malaria, acquired immunodeficiency syndrome, heart disease, stroke, arteriosclerosis, diabetes and cancer etc. 10,11) It has been reported that some synthetic antioxidant compounds such as butylated hydroxytoluene and butylated hydroxyanisole, commonly used in processed foods, have side effects.…”

POTENTIAL ROLE OF Jasonia montanta AND Jasonia candicans AGAINST ALZHEIMER'S DISEASE: ASSESSMENT OF OXIDATIVE STRESS AND GENE EXPRESSION CHANGES IN AD-INDUCED RATS

“…Hussein and Abdel-Gawad (2010) study greatly supported our results in this concern as they stated that BNO level is significantly depleted after J. montana treatment in rats-induced cholestasis. The high content of flavonoids and phenolic compounds in J. montana extract (Hussein and Abdel-Gawad, 2010) and J. Candicans (Hammerschmidt et al, 1993) may contribut in this effect.…”

“…This gives rise to the elevated levels of BNO that are apparently involved in neurodegeneration by different mechanisms, including oxidative stress and activation of intracellular signaling mechanisms (Lüth et al, 2001). (Soliman et al, 2009) and J. candicans (Hammerschmidt et al, 1993) have been found to exihibit antilipid peroxidative effect (Dasgupta and De, 2007;Liu et al, 2008) due to their ability to inhibit H 2 O 2 -induced lipid peroxidation (Ammar et al, 2009). Flavonoids are able to inhibit lipid peroxidation on the mitochondrial membrane, thus these compounds possess good antilipidperoxidat activity (Sugihara et al, 1999) which indicates the pharmacological potential of flavonoids against pathological processes related to oxidative stress (Andarwulan et al, 2010).…”

“…The herb has a strong aromatic odor and is used in traditional medicine for diarrhea, stomachache, and chest diseases. A literature survey indicated that some mono-and sesquiterpenes (Ahmed and Jakupovic, 1990;Ahmed, 1991), flavonoids (Ahmed et al, 1989), and essential oils (Hammerschmidt et al, 1993) have been reported from the plant. The different extracts of the plant were also screened for hypoglycemic and antidiabetic activities (AL-Howiriny et al, 2005).…”
