methanolic extracts of five native species of salvia from the labiatae family were evaluated for antioxidant activity in low-erucic acid rapeseed oil using the schaal oven test at 60°c, with deterioration monitored by determination of peroxide value, conjugated diene content and p-anisidine value. the activity of the salvia extracts was compared with that of tbhq, ascorbyl palmitate, and extrac...

Background: Common sage (Salvia officinalis) is a popular culinary and medicinal herb. A literature survey has revealed that sage oils can vary widely in their chemical compositions. The purpose of this study was to examine sage essential oil from different sources/origins and to define the possible chemotypes of sage oil. Methods: Three different samples of sage leaf essential oil have been ob...

The aim of this research was to determine the chemical composition and insecticidal activity of the essential oil of Curcuma wenyujin Y.H. Chen et C. Ling rhizomes against the booklouse Liposcelis bostrychophila Badonnel and to isolate any insecticidal constituents from the essential oil. The essential oil of C. wenyujin rhizomes was obtained by hydrodistillation and analyzed by GC-MS. A total ...

Salvia officinalis L. or Dalmatian sage is a perennial low shrub which is native of the western part of the Balkan Peninsula [1]. In Romania, the Salvia genus contains 15 species including Salvia officinalis [2]. According ...

the composition of the volatile oils obtained from the aerial parts of artemisia deserti krasch. and a. oliveriana j. gayex dc. was analyzed by gc and gc/ms. while the oil of a. deserti contained camphor (45.5%), 1,8-cineole (16.7%), piperitone (8.6%), ?-pinene (5.7%) and isoborneol (3.2%), the oil of a. oliveriana contained ?-thujone (65.4%), camphor (11.5%), 1,8-cineole (9.2%) and pinocavone ...

the achillea l. genus has a wide distributional range, and the differences in oil composition may be affected by different environmental factors such as soil mineral fertilization, the climate conditions and the culture site. to evaluate the effect of temperate climate on content and chemical combination of essential oil of achillea filipendulina lam,  a. arabica kotschy and a. eriophora dc., t...

This study aimed to assess the chemical composition of essential oils Elsholtzia blanda (Benth.) Benth. in Lam Dong Province, Viet Nam, and evaluate their biological activities. Essential obtained by hydro-distillation aerial parts E. were analyzed gas chromatography-mass spectrometry (GC-MS). Thirty-one constituents identified oil, oil was predominantly monoterpenoid, with camphor (25.14%), ca...

The chemical composition of the essential oils of flower at the pre-flowering, full-flowering and post-flowering stage of A. annua was analyzed by GC and GC/MS and sixty-two components were identified. The main compounds in the pre-flowering oil were β-myrcene (37.71%), 1, 8-cineole (16.11%) and camphor (14.97%). The full-flowering oil contained predominantly caryophyllene (19.4%), germacrene D...
