The composition of the essential oil of the fruits, leaves and stems of Daucus glaber Forssk has been studied by GC/MS. It was found that, the essential oil of the fruits consists of monoterpene hydrocarbons (limonene and sylvestrene are the majors) and phenylpropanoids (elemicin is the major). Sylvestrene has never been reported before in the essential oil of any Daucus species. The study of t...
chemical composition of the essential oils extracted from the leaves, stems, flowers and seeds of heracleum rechingeri manden. were analyzed by gc and gc/ms. twenty-four components were characterized for the leaf oil with octyl acetate(47.2%), octanol(15.2%) and e-caryophyllen (5.7%) as the main constituents. 25 compounds were identified in the stem oil with elemicin (65.3%), octyl acetate (13...
Certain alkenylbenzenes (AB), flavoring chemicals naturally occurring in spices and herbs, are established to be cytotoxic and hepatocarcinogenic in rodents. The purpose of the present study was to determine the DNA damaging potential of key representatives of this class using the Turkey Egg Genotoxicity Assay. Medium white turkey eggs with 22- to 24-day-old fetuses received three injections of...

در این پژوهش به تجزیه شیمیایی و بررسی اسانس حاصل از دو گیاه ferula foetida و prangos uloptera پرداخته شده است . دو گیاه پس از جمع آوری به اجزاء برگ ، گل و ساقه تفکیک و در سایه تحت جریان ملایم هوا خشک شدند سپس با استفاده از دو روش تقطیر با آب و headspace از نمونه های گیاهی اسانس گرفته شد . همچنین اثر آنتی اکسیدانی حاصل از عصاره متانولی ferula foetida نیز مورد بررسی قرار گرفت . ترکیبات عمده و ...
This study is part of a project devoted to determining the scent all orchid species present in Basilicata. All analyses were performed by using solid-phase microextraction technique coupled with gas chromatography-mass spectrometry. The eight belonging Orchis genus was investigated. In case O. anthropophora, caryophyllene, tetradecanal and hexadecanal main components aroma; purpurea, 3,5-dimeth...
The volatile components of the leaves of four species and five varieties of the section Bicornes of Heterotropa were examined by gas chromatography and gas chromatograph-mass spectrometry. The analytical results showed that the species of the section contain phenylpropanes, terpenes, and a paraffin as main components. The components have been used to construct phylogenetic trees of the section ...
