The essential oil from the dried leaves of Chromolaena odorata (L.) R.M. King & H. Rob. was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). The major components were α-pinene (42.2%), β-pinene (10.6%), germacrene D (9.7%), β-copaen-4α-ol (9.4%), (E)caryophyllene (5.4%), and geijerene/pregeijerene (7.5%). The oil was screened for antimicrobial activity...

The experiment was aimed to study the chemical constituents of essential oils from two Pimpinella L. species including P. deverroides - Boiss, and P. tragium Vill. growing wild in Iran. To do this, the essential oil of fruits of two P. tragium populations (Sefidkhani and Hesar, Markazi province, Iran) and one population of P. deverroides (Kerend, Kermanshah province) were extracted by a Cleveng...

Heterotrophic cell suspension cultures of Ruta graveolens were established by reversion of photom ixotrophic cultures without any change in the chemical composition of the growth medium. The heterotrophic cultures were qualitatively and quantitatively analyzed by gaschromatography and mass spectroscopy for volatile compounds. The terpenoid hydrocarbons geijerene and pregeijerene, C6-C8 ketones,...

the experiment was aimed to study the chemical constituents of essential oils from two pimpinella l. species including p. deverroides - boiss, and p. tragium vill. growing wild in iran. to do this, the essential oil of fruits of two p. tragium populations (sefidkhani and hesar, markazi province, iran) and one population of p. deverroides (kerend, kermanshah province) were extracted by a cleveng...

Abstract Citrus fruits are among the most important economical crops, because of their nutritional value, medicinal importance, and unique flavor. Gas liquid chromatography-mass spectrometry hydro-distilled oil from root resulted in identification 110 compounds with germacrene B (22%), aromadendrene (21.6%), α-santalene (7.1%), geijerene (4,81%), D (4.3%), limonene (3.4%) as major constituents....

abstract the genus hymenocrater, belong to the lamiaceae family, consist of 21 species throughout the world. in iran, about 9 species are present, of which some are endemic. plants belonging to these genuses are pharmacologically active and have been used in folk medicine all around the world. the aim of the present study was to detect the essential oils composition of hymenocrater longiflorus ...

in order to investigation the effects of seed origin and planting date on yield  and essential oil of pimpinella affinis, a field experiment was carried out in alborz research center in 2007. this experiment was performed under factorial in the base of (rcbd) with three replications. the treatments were included locations of seeds collection and planting dates. essential oils were extracted fro...

in this study, the aerial parts of pimpinella puberula were collected from ramhormoz and mashhad (khuzestan and khorasan provinces) at the vegetative, flowering and seeding stages. essential oils from the whole aerial parts as well as stem/leaf, inflorescence, unripe and ripe seeds, were isolated by hydro-distillation. the yields of essential oil obtained from the ramhormoz samples were 0.49%, ...
