Chemical Composition and Antimicrobial Activity of Essential Oils of Genista ulicina and G. vepres

Abstract

The hydrodistilled oils from the aerial parts of Genista ulicina Spach. and G. vepres Pomel., which are endemic to Algeria, were analyzed by gas chromatography-mass spectrometry (GC-MS). In the oil of G. ulicina, 41 compounds were identified representing 90.8% of the total oil, and in G. vepres, 61 compounds representing 84.5% of the total oil. The analyses showed that the major constituents of the oils were lauric acid (14.3%-8.5%), myristic acid (11.5%-5%), linoleic acid (3.1%-11.7%) and palmitic acid (18.6%-26.4%). Using a diffusion method, the oils showed significant antibacterial activities against Escherichia coli (ATCC 25922), Pseudomonas aeruginosa (ATCC 27853) and Staphylococcus aureus (ATCC 25923).

Osteoblastic activity of ethanolic extract and volatile compounds from Er-Zhi-Wan, a famous traditional Chinese herbal formula

“…Many researches showed that volatile compounds obtained from many plants are responsible for their pharmacological activities just as non-volatile compounds in herbs (Lograda et al, 2010;Ho et al, 2010;Wei et al, 2012;Sharma et al, 2012;Rahimi et al, 2011). Both EP and FLL contain rich volatile compounds, from which we could always smell the strong fragrance.…”

A New Triterpene Glucoside from Genista numidica

“…The genus Genista (Fabaceae family) includes about 90 species of shrubs or small trees in the Mediterranean area and in Western Asia, of which 23 grow in Algeria [1]. This genus is known as a good source of active secondary metabolites like essential oils [2][3][4], saponins [5], quinolizidine alkaloids [6], and flavonoids [7]. A wide range of biological and pharmacological properties has been reported for this genus, such as antimicrobial [8], antioxidant [9], and antiproliferative activities [10].…”
