The aim of this study was to investigate the chemical constituents of Lindera erythrocarpa essential oil (LEO) by gas chromatography-mass spectrometry and evaluate their inhibitory effect on the expression of pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Fifteen compounds, accounting for 63.7 % of the composition of LEO, were identified. The main compounds we...

The phytoconstituents of the essential oil isolated by hydrodistillation and solvent extracts (PE, BZ, DCM, EtOAc EtOH) mature rhizomes turmeric (Curcuma pseudomontana) were analyzed GC–MS. major constituents identified in Benzofuran (6.93%), γ-Curcumene (11.18%), β-Elemenone (22.14%), Germacrone (15.15%), Phenol, 2-Methyl-5-(1,2,2-trimethylcyclopentyl)- (29.58%), Germacrene (8.78%), Italicene ...

A study of the chemical composition essential oil obtained from aerial parts Salvia verticillata L., growing in Georgia, was carried out. The percentage dominant components determined by internal integration, component leaves is caryophyllene (10.15 %), spathulenol (9.8 valeranone (11.9 and flowers, germacrene D (17.2 (9.43 %). ratio terpene compounds flowers oxygenated sesquiterpenes are 38.43...

Curcuma purpurascens Bl., belonging to the Zingiberaceae family, is known as temu tis in Yogyakarta, Indonesia. In this study, the hydrodistilled dried ground rhizome oil was investigated for its chemical content and antiproliferative activity against selected human carcinoma cell lines (MCF7, Ca Ski, A549, HT29, and HCT116) and a normal human lung fibroblast cell line (MRC5). Results from GC-M...

The chemical composition of the essential oil of fruits of Pimpinella haussknechtii. was studied by GC-MS. After GC-MS analysis, one unknown component (56.7%) was observed, which was not characterized in the GC-MS library. The essential oil of P.haussknechtii was injected to HPLC using YMC-Pak-Sil column (250 × 20 mm) with gradient system of hexane (A), and hexane: ethyl acetate, 9:1 (B) to yie...

Background: Lantana montevidensis (L. montevidensis) is native to Brazil, the tea and infusions of the dried leaves have been used in folk medicine. Previous study of L. montevidensis leaves has resulted in the isolation of ten anti-proliferative fl avones. Also, the essential oil of the Brazilian L. montevidensis leaves was investigated for its chemical composition and antimicrobial activity. ...

the essential oil of stachys lavandulifolia vahl (lamiaceae) was isolated by hydrodistillation of the aerial parts of the plant, with a yield of 0.25%. the chemical composition of volatile oil was analyzed by capillary gc and gc/ ms. the main components were germacrene-d (13.2%), ?-phellandrene (12.7%), ?-pinene (10.2%), myrcene (9.4%), ?-pinene (8.4%) and z-?-ocimene (5.8%).

The volatile constituents of the aerial parts of Varthemia. persica DC. var. persica, growing wild in Iran, were investigated by GC-MS. Sixty seven constituents were identified. ?-Cadinene (9.7%), Selin-11-en-4-?-ol (5.30%), Germacrene D (4.9%), Bicyclogermacrene (4.7%), ??Muurolene (4.7%), ?-Eudesmol (4.52%), ?-Himachalen oxide (3.6%), ?-Eudesmol (3.54%), ?-Bourbonene (3.21%) were found to be...

Volatile oils from leaves and flowers of Aloysia gratissima were investigated for their chemical composition and antimicrobial activity against the bacteria Bacilus subtilis, Staphylococcus aureus, Salmonella choleraesuis, Pseudomonas aeruginosa, Streptococcus pneumoniae and the Candida albicans yeast. The minimum inhibitory concentrations (MIC) of the oils were determined by the micro-dilution...
