The chemical variations of the essential oil from the aerial parts of Laurus nobilis L. (Lauraceae) have been studied. Plant material has been harvested at each phenological status (vegetative, before anthesis, full flowering and seed-bearing). The oils were obtained by hydrodistillation of the air-dried samples. Analysis by GC and GC-MS of the essential oils has allowed to identify 39 compound...

Oleoresin samples collected from Pinus sylvestris L. trees from Acıpayam, Çal and Çamlıbel, three different locations in Denizli-Turkey. The constituents of the turpentine oil, obtained by hydrodistillation of oleoresin of Pinus sylvestris L., were identified by GC-MS. Fifty four constituents were detected from the turpentine oil, which constituted about between 96.2% and 98.2% of the total amo...

The volatile oil obtained by hydrodistillation of the petals of Rosa damascena Mill. (Rosaceae) was analyzed by gas chromatography and gas chromatography/mass spectrometry (GC/MS). The yield of the oil was 0.12 % (v/w). Fifty compounds representing 99.06 % of the oil were characterized. The volatile oil was found rich in sesquiterpenes and aliphatic components, consisting of two monoterpenic es...

The essential oil of Heracleum sphondylium L subsp. ternatun (Velen.) Brummit (Umbelliferae) was isolated from crushed seeds by means of hydrodistillation and analyzed by GC and GC/MS. Major components were identified as 1-octanol (50.3%), octyl butyrate (24.6%), and octyl acetate (7.3%). Furthermore, antimicrobial activity of the oil was evaluated using microdilution broth and agar diffusion m...

Data on in vitro evaluation of extracts of three species of the Asteraceae family on the development of Trichostrongylidae eggs in sheep are presented. Egg hatchability was tested using herbal extracts prepared in a Soxhlet extractor, and using hydrolate prepared by means of hydrodistillation. The laboratory tests showed that the ethanol extract from flowers of the species Aster lanceolatus pre...

Helichrysum italicum (Roth) G. Don (Asteraceae), also known as immortelle, usually grows in the Mediterranean area. The composition of essential oil (EO) immortelle is a mixture various aromatic substances, mainly monoterpenes and sesquiterpenes. Distillation most widely used method for extraction EO although yield very low (<1%). In this work, we aim to investigate how use different distill...
