Differences in female/male plant metabolism for dioecious species are poorly understood but relevant if the economic exploitation of such resources is objective. In this work, composition Baccharis tridentata Vahl essential oil from flowering aerial parts male and female plants was analysed separately by GC-MS (gas chromatography-mass spectrometry; area percentage internal standard), CPGC-MS (c...

The aim of the present study was to investigate the essential oils isolated from flower and leaf in order to get insight into similarities and differences as to their aroma-active composition. The essential oil obtained from the two parts were analyzed by gas chromatography-mass spectrometry and gas chromatography olfactometry (GC-O). Flower and leaf oils, 38 and 36 constituents, representing 9...

the essential oil obtained by hydrodistillation of flowers of calycanthus floridus l. var.oblongifolius (nutt.) d.e. boufford & s.a. spongberg, planted in sabzevar, khorasan province(iran), was analyzed by gc and gc/ms. eighteen compounds representing 90.1% of theflower oil of calycanthus floridus l. var. oblongifolius were identified, among them 1,8-cineol(33.1%), bornyl acetate (14.1%), α-pin...

Ferulago macrocarpa (Fenzl) Boiss. commonly known as Chavil e Roshanball in Persian is a medicinal and aromatic plant from the Apiaceae family that grows in the west of Iran. The aim of this study was to investigate the phytochemical components, phenolic contents, antioxidant and antibacterial activities of hydroalcoholic extracts of F. macrocarpa flower and leaf from Lorestan...

callus and suspension cultures of lavandula angustifolia mill. (lamiaceae) were established and the effect of different culture media on growth rate was investigated. terpenoids added to suspension culture to investigate their biotrans-formation. all samples were analyzed by gas chromatography (gc) and gc-mass spectroscopy (ms). octan-1-ol, citronellol, linalool, borneol and geraniol were biotr...

Background Anthriscus caucalis is a non-native plant in North America with invasive potential. As part of our interests essential oils the Great Basin, wild-growing sample A. was collected southwestern Idaho. Methods The obtained by hydrodistillation and analyzed gas chromatographic methods (GC–MS, GC–FID, chiral GC–MS). Results major components oil were cis-chrysanthenyl acetate (42.3%), myrce...

The essential oil obtained by steam distillation of dried aerial parts of Ambrosia trifida L. from Northeast China was analyzed by GC and GC-MS. The essential oil yield based on dried plant material was 0.12% and thirty-five compounds (corresponding to 86.7% of the total weight) were identified. The main components were: bornyl acetate (15.5%), borneol (8.5%), caryophyllene oxide (8.3%), alpha-...

A bulk collection of terminal branchlets was made from J. pinchotii and subjected to drying at 42oC (24 hrs), then stored for up to 24 mos. at 22oC (room temperature, RT). The oils were distilled and analyzed from fresh, 0.5, 1, 2, 4, 8, 16, and 24 mos. storage at RT. The oil yields showed a slight decline initially, but remained fairly constant. Camphor, camphene hydrate and citronellal declin...
