Nepeta L. is one of the important genus in Lamiaceae family. It includes ca. 300 herbaceous species and mostly grows Eurasia. represented Turkey by 40 taxa these 16 are endemic. commonly utilized traditional medicine local people, primarily as spasmolytic, diuretic, bronchodilator agents. As a consequence studies on taxa, terpenoids flavonoids have been identified most common components. In thi...

Salvia rosmarinus Spenn (synonym: Rosmarinus officinalis L.) is economically and medically important grows naturally in Al-Marj (Libya). Macro, micro morphological chemical characteristics were studied. Leaf venation, leaf anatomy compounds of essential oils carried out according to traditional methods. The objective the present study provide detailed description this species. Morphological cha...

Glucuronic acid has been found in the urine of a variety of experimental animals (1, 2), chiefly in the form of conjugation products with phenolic substances and steroids (2, 3). The presence of glucuronides is widely interpreted as evidence of the ability of the animal organism to make use of the conjugation reaction to eliminate a great variety of toxic substances. Variations in the aglucone ...

Stachys L. one of the biggest genus of the Lamiaceae family comprises about 200-300 species.  In this research, aerial parts essential oil composition and content of Stachys lavandulifolia Vahl (Lamiaceae)at different stages (vegetative, full flowering and initial fruiting stages) is reported. The oils obtained by water distillation method (Clevenger apparatus) and analyzed by GC and GC/MS. The...

A new chiral compound was synthesized based on L-borneol. A cholesteric liquid crystal (LC) electrolyte solution was prepared by adding it as a chiral inducer to a nematic LC. A chiral poly(3,4-ethylenedioxythiophene) (PEDOT*, * = asymmetry) film was prepared by electrochemical polymerization in the induced cholesteric LC. The PEDOT* film showed a maximum absorption band due to a π–π* transitio...

Flower fragrance compounds were found to be produced from the precursor solution obtained from flower buds by crude enzyme prepared from the flowers at the opening stage. GC and GC-MS analyses showed the formation of volatile aroma constituents from the precursor solution of Jasminum polyanthum F, Jasminum sambac Ait, and Gardenia jasminoides E, but none in the case of Osmanthus fragrans L. The...

It was previously reported by the authors (1) that, in a normal rat with daily administration of 100 mg/kg borneol and intraperitoneal injection of 400 mg/kg glucuro nolactone for the period of 13 days, the amounts of total glucuronic acid, of o-glucuronide and of 1-ascorbic acid excreted in rat's urine, increased significantly, and that, in a bilate rally adrenalectomized rat administrated dai...

AIM The purpose of this study was to evaluate how increasing NaCl salinity in the medium can affects the essential oils (EOs) composition and phenolic diterpene content and yield in leaves of Salvia officinalis L. The protective role of such compounds against NaCl stress was also argued with regard to some physiological characteristics of the plant (water and ionic relations as well as the leaf...

background & aim: a simple and rapid microwave- assisted extraction (mae) procedure was developed and optimized for the isolation of borneol and bornyl acetate from ferulago macrocarpa. ferulago macrocarpa (apiaceae) is an endemic plant in iran. experimental: dried powdered aerial parts of plants were soaked in water and irradiated with microwave in a clevenger extraction approach under opt...
