Chemical Composition of the Stem Oil of Aristolochia indica L.

Essential oil from dry matured stem of Aristolochia indica Linn. family Aristolochiaceae was investigated by GC and GC/MS. A total of 15 compounds were identified, representing 91.2% of the total oil. The major constituents of oil were trans-pinocarveol (24.2%), a-pinene (16.4%) and pinocarvone (14.2%)

Hypericum sp.: essential oil composition and biological activities

Phytochemical composition of Hypericum genus has been investigated for many years. In the recent past, studies on the essential oils (EO) of this genus have been progressing and many of them have reported interesting biological activities. Variations in the EO composition of Hypericum species influenced by seasonal variation, geographic distribution, phenological cycle and type of the organ in which EO are produced and/or accumulated have also been reported. Although many reviews attributed to the characterization as well as biological activities of H. perforatum crude extracts have been published, no review has been published on the EO composition and biological activities of Hypericum species until recently (Crockett in Nat Prod Commun 5(9):1493–1506, 2010; Bertoli et al. in Global Sci Books 5:29–47, 2011). In this article, we summarize and update information regarding the composition and biological activities of Hypericum species EO. Based on experimental work carried out in our laboratory we also mention possible biotechnology approaches envisaging EO improvement of some species of the genus.Fundação para a Ciência e a Tecnologia (FCT) - project PTDC/AGR AAM/70418/2006, SFRH/BD/ 13283/2003

The oil of fumana thymifolia (L.) spach ex webb from Greece

The genus Fumana comprises nine species, which are naturalized in Europe. Fumana thymifolia (L.) Spach ex Webb is a dwarf shrub, growing on dry, rocky, stony or sandy ground (1,2). The essential oil of the aerial parts of Fumana thymifolia was investigated by GC-MS. Thirty-eight components were identified in the oil representing 89.5%. The major compounds were pulegone (19.8%) and nonanal (9.5%). © 2001, Taylor & Francis Group, LLC. All rights reserved

Essential Oil of Calamintha nepeta subsp. glandulosa from Greece

The essential oil of spontaneous plants of Calamintha nepeta (L.) Savi subsp. glandulosa (Req.) P.W. Ball with mint-like character were investigated by GC/MS. Twenty three components were identified in the oil representing 99.7%. The major compounds were pulegone (41.0%), menthone (32.0%), piperitone (7.3%) and piperitenone (7.0%). © 2001, Taylor & Francis Group, LLC. All rights reserved

Essential oil composition of Turkish herbal tea (Salvia aucheri Bentham var. canescens Boiss. & Heldr.)

The essential oil of the aerial parts of Salvia aucheri var. canescens, collected from two different locations (Gülnar, sample A; and Silifke, sample B) growing endemic in Turkey, were analysed by GC-MS. The oil yields of dried plants (v/dw) obtained by hydrodistillation were 1.4% and 1.7%, respectively. Forty-two compounds were identified, representing 98.6% and 99.5% of the oils from the two locations. The main constituents of the oils were: 1,8-cineole (32.3%, 28.6%), camphor (18.9%, 22.8%), borneol (8.2%, 8.9%), α-pinene (6.3%, 9.0%) and β-pinene (5.3%, 6.2%), respectively. The oils consisted of monoterpenic hydrocarbons (21.3%, 27.4%), oxygenated monoterpenes (66.4%, 64.9%), sesquiterpene hydrocarbons (6.3%, 3.1%) and oxygenated sesquiterpenes (4.1%, 4.1%), respectively. 1,8-Cineole and camphor were the major components of S. aucheri. var. canescens.

Composition and antifungal activity of the oil from aerial parts and rhizomes of valeriana dioscoridis from Greece

The essential oils from aerial parts and rhizomes of Valeriana dioscoridis Sibth. et Sm. were investigated by GC/MS. The major components, among the identified 55, were patchouli alcohol (13.4% and 15.7%, respectively), α-pinene (6.7% and 8.6%, respectively), and β-pinene (5.8% and 7.0%, respectively). Furthermore, the antifungal activity of the oil from rhizomes and its main component patchouli alcohol was evaluated. The essential oil tested showed higher antifungal properties than patchouli alcohol. The commercial fungicide Bifonazole, which was used as a control, showed lower antifungal potential than the oil and patchouli alcohol investigated. © 2004, Taylor & Francis Group, LLC.
