This study investigates the variations in chemical profiles and biological activities (antioxidant cytotoxic) of Eplingiella fruticosa from state Sergipe, an endemic species Northeast region Brazil. The essential oils were extracted six populations by hydrodistillation analyzed GC/MS-FID. Cluster analysis was performed with data constituents oils, then a dissimilarity matrix, based on Euclidean...

objective(s):various species of genus trigonella are important from medical and culinary points of view. the essential oil of trigonella torbatejamensis ranjbar as an endemic plant in iran has not been studied previously. the essential oil of this plant was analyzed by different methods for identification of its components. materials and methods: the essential oil composition of aerial parts of...

Terpene synthases (TPS) catalyze the cyclization of acyclic prenyl diphosphate precursor and are responsible for abundance natural product terpene in nature. The biosynthesis terpenoid by nonseed plant TPS is not well understood due to highly dynamic feature reaction unavailability enzyme structure. Here we discovered a class I JeST4 from Jungermannia exsertifolia elucidated its catalytically a...

The genus Artedia L. (Apiaceae) is represented in Turkey by 485 species and altogether 511 taxa. rate of endemism 37.7%. plant material was collected from the province Kahramanmaraş, Turkey. essential oils fruits aerial parts were obtained hydrodistillation using a Clevenger type apparatus. Chemical compositions analysed GC-FID GC-MS techniques. main components oil characterized as 1-octadecano...

BACKGROUND Several studies have shown that species of the genus Hyptis, have promising antimicrobial and antifungal effects. OBJECTIVES Identify of chemical constituents of essential oil from leaves of Hyptis martiusii and evaluate its effect against bacterial strains by direct and gaseous contact. MATERIALS AND METHODS Essential oil was extracted from leaves of Hyptis martiusii Benth using...

The chemical composition of the essential oil of fruits of Pimpinella haussknechtii. was studied by GC-MS. After GC-MS analysis, one unknown component (56.7%) was observed, which was not characterized in the GC-MS library. The essential oil of P.haussknechtii was injected to HPLC using YMC-Pak-Sil column (250 × 20 mm) with gradient system of hexane (A), and hexane: ethyl acetate, 9:1 (B) to yie...

A review on a medicinal plant belong to family Labiatae has been made in the Kingdom of Saudi Arabia. Among reported flora Arabia, highest species. total 23 species with high value. detail 12 had done know their phytochemical constituents, uses and pharmacological properties. In this we also explore chemical constituents present each unique list 3D structures. (E)-2-Hexenal, 1,8-Cineole, Bicycl...

The mechanisms and conditions affecting expression of systemic induced resistance (SIR) in pine are not clearly understood. Two hypotheses were tested here: that SIR against a pathogen induced by either a pathogen or an insect involves coordinated shifts in phloem secondary metabolism; and that fertility affects the production of these compounds. To test these hypotheses, a tripartite system wa...
