Foeniculum Vulgare

Medicinal plants are considered modern resources for producing agents that could act as alternatives to antibiotics in demeanor of antibiotic-resistant bacteria. The aim of the study was to evaluate the chemical composition and antibacterial activities of essential oil of Foeniculum vulgare (FV) against Pseudomonas aeruginosa and Bacillus subtilis. Gas chromatography mass spectrometry was done to specify chemical composion. As a screen test to detect antibacterial properties of the essential oil, agar disk and agar well diffusion methods were employed. Macrobroth tube test was performed to determinate MIC. The results indicated that the most substance found in FV essential oil was Trans-anethole (47.41 %), also the essential oil of FV with 0.007 g/ml concentration has prevented P. aeruginosa and with 0.002 g/ml concentration has prevented B. subtilis from the growth. Thus, the research represents the antibacterial effects of the medical herb on test P. aeruginosa and B. subtilis. We believe that the article provide support to the antibacterial properties of the essential oil. The results indicate the fact that the essential oil from the plant can be useful as medicinal or preservatives composition.

In the present study, chemical composition and antibacterial properties of essential oil obtained from the aerial parts of the Melicope pteleifolia (Champ. ex Benth.) T.G Hartley in Dalat were evaluated. Essential oil was isolated through hydro-distillation. Twenty-nine constituents comprising 100% of the essential oil were characterized by gas chromatography/mass spectrometry (GC-MS) techniques. The major compounds in the essential oil were (+)-Sabinene (34.73%), Cis-α-bergamotene (13.15%), Z-α-trans-bergamotol (5.28%), β-mycrene (4.98%), and 1,3,6-octatriene, 3,7-dimethyl-(4.71%). Antibacterial activities of Melicope pteleifolia essential oil were investigated against Gram-positive and-negative bacteria. Results showed significant activities against Streptococcus pyogenes and Escherichia coli using an agar well diffusion method. The application of this essential oil in preventing and eliminating bacteria could be useful in fields as medicine and cosmetics.

Hedychium puerense, a perennial rhizomatous herb, is used as an ornamental, medicinal, and edible plant in Yunnan Province, China. Essential oils from Hedychium plants are widely used in perfumes and traditional medicine, but there are no studies on the constituents and bioactivities of H. puerense essential oil (EO). Therefore, this study was designed to explore the chemical composition, antibacterial, enzyme-inhibitory, and anti-inflammatory activities of H. puerense rhizome EO. The gas chromatography with flame ionization or mass selective detection (GC-FID/MS) results indicated that H. puerense EO was mainly composed of linalool (26.5%), β-pinene (18.6%), γ-terpinene (12.1%), terpinen-4-ol (7.7%), α-pinene (5.8%), sabinene (4.9%), E-nerolidol (4.1%), and p-cymene (3.6%). For biological activities, H. puerense EO displayed broad-spectrum antibacterial properties against Enterococcus faecalis, Bacillus subtilis, Staphylococcus aureus, Proteus vulgaris, Pseudomonas aeruginosa, and Escherichia coli with diameter of inhibition zone (DIZ) values ranging from 7.44 to 10.30 mm, a minimal inhibitory concentration (MIC) of 3.13–6.25 mg/m), and a minimal bactericidal concentration (MBC) of 3.13–12.50 mg/mL. Moreover, the EO significantly inhibited acetylcholinesterase (AChE) (IC50 = 0.94 ± 0.02 mg/mL) and butyrylcholinesterase (BChE) (IC50 = 1.32 ± 0.06 mg/mL) activities, and exhibited a moderate inhibitory effect on α-glucosidase (IC50 = 5.42 ± 0.32 mg/mL) and tyrosinase (IC50 = 3.23 ± 0.21 mg/mL). Furthermore, the EO significantly suppressed the secretion of the pro-inflammatory mediator, nitric oxide (NO) (99.23 ± 0.26%), cytokines tumor necrosis factor-α (TNF-α) (97.14 ± 0.11%), and interleukin-6 (IL-6) (82.42 ± 0.16%) in lipopolysaccharide (LPS)-stimulated RAW264.7 cells at 250 μg/mL without cytotoxicity. Hence, H. puerense EO can be considered a bioactive, natural product that has great potential for utilization in the fields of food, cosmetics, and pharmaceutics.

Plants constitute an important source of secondary metabolites in which essential oils are well-known for their use in various domains such as pharmacy, therapeutic, cosmetology and foods. In vitro antimicrobial and antioxidant properties of Ocotea auriculiformis Kost. (Lauraceae) leaves essential oil is demonstrated and its chemical composition is reported in the present study. The essential oil from Ocotea auriculiformis Kost. (Lauraceae) leaves, an endemic plant of Madagascar was extracted by hydrodistillation method. Chemical composition using GC, GC/ MS and NMR13C methods showed that the essential oil contained around 47 products in which 93.95% were identified. Known compounds are constituted by 74.7% of hydrocarbons and 19.25% of oxygenated products. The essential oil is rich in sesquiterpene and monoterpene. In vitro antibacterial capacity of the essential oil was assessed by disc method against human and food pathogens. Bacillus cereus and Streptococcus pneumoniae were very sensitive to the essential oil with 11 mm and 25 mm of inhibition zone respectively. The MIC of the essential oil was 1mg/mL for Bacillus cereus and 0.25 mg/mL for Streptococcus pneumoniae. MBC values were 2.5 mg/mL and 0.5 mg/mL, respectively. The ratio MBC/MIC for both strains was inferior to 4 concluding hence that the essential oil has bactericidal effect against the two sensitive strains. In vitro antioxidant capacity of the essential oil was performed according to qualitalive (TLC) and quantitative (measure of DPPH radical scavengening) methods. The essential oil showed antioxidant activity with IC50 value of 0.35 mg/mL.
