The chemical composition of the essential oil obtained from the aerial flowering parts of Ziziphora clinopodioides subsp. bungeana (Juz.) Rech. f. was analyzed by GC and GC-MS. Thirty-two components representing 97.1% of the total oil were identified. Oxygenated monoterpenes (94.3%) were the predominant fraction of the oil with pulegone (65.2%), isomenthone (11.9%), 1,8-cineole (7.8%) and piper...

In this review, the chemical compositions and bioactivities of essential oils isolated from Arisaema Homalomena species, two large genera belonging to Araceae family, have been reported for first time. Accordingly, plants consisted some groups, including monoterpene hydrocarbons, oxygenated monoterpenes, sesquiterpene sesquiterpenes, etc. addition, their major compounds possessed biological act...

the chemical composition of the essential oil of fruits of pimpinella haussknechtiiboiss.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.hauskenekhtii 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...

Abstract Crude citronella oil contains a mixture of components such as group hydrocarbon monoterpenes compounds, oxygenated monoterpenes, and sesquiterpenes. Therefore, it has low economic value functional value. A single component with high purity can be obtained through chemical physical properties analysis. Based on the constituent oil, boiling points each are quite adjacent so that separate...

Leucas virgata Balf.f. (Lamiaceae) was collected from the Island Soqotra (Yemen) and its essential oil was obtained by hydrodistillation. The chemical composition of the oil was investigated by GC and GC-MS. Moreover, the essential oil was evaluated for its antimicrobial activity against two Gram-positive bacteria, two Gram-negative bacteria, and one yeast species by using broth micro-dilution ...

Casearia genus (Salicaceae) is found in sub-tropical and tropical regions of the world and comprises about 160-200 species. It is a medicinal plant used in South America, also known as "guaçatonga", "erva-de-tiú", "cafezinho-do-mato". In Brazil, there are about 48 species and 12 are registered in the State of Rio de Janeiro, including Casearia sylvestris Sw. There are many studies related to th...
