Background: The chemical composition and bioactivities of essential oils (EOs) of fingered citron (Citrus medica L. var. sarcodactylis (Noot.) Swingle) are considerably sensitive and lapsible during high-temperature processing of traditional separating techniques. In the present research, vacuum distillation and ultrafiltration were utilized in order to process the concentrated juice from finge...

Background and objectives: Pterocarya fraxinifolia Lam. is a deciduous, fast-growing tree from walnut family. The stem barks and fruits of the plant have been used as diaphoretic in traditional medicine. Variation in the quantity and quality of the essential oil and extract of stems of the plant at different developmental stages was evaluated in addition to assessing t...

The focus of the present study was to investigate the chemical composition of essential oil of Salvia hydrangea DC. ex Benth. growing wild in Kiasar-Hezarjrib, Iran. In addition, effects of altitude and some soil properties on the essential oil quality and quantity of S. hydrangea was identified. The samples collected from two altitudes (1100 and 2000 m) in blossoming period, were analyzed by h...

Background: In the recent decade, artificial drying has been one of the most important needs of the pharmaceutical industries. In addition, different drying methods have different effects on the quantity and quality of the essential oils produced from medicinal plants. Objective: The main objective of this study was to evaluate the effects of different drying methods (shade and oven drying a...

Achillea moschata Wulfen (Asteraceae) is an endemic species growing on the Alps and traditionally used in several medicinal remedies. For its aromatic properties, it is also collected for food purposes. Chemical content and biological activity of A. moschata oil are not extensively studied. We investigated whether the different lithological and geomorphological features of two alpine areas incl...

A study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (Ocimum basilicum L.). The research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. The experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

Soybean oil contains 14 fatty acids and five of them, C16:0, C18:0, C18:1, C18:2, and C18:3, are considered essential fatty acids for proper human nutrition. Increasing the oil content and improving the ratio of the various fatty acids in soybeans is a goal for many breeding programs. The objective of this research was to evaluate the relationship between grain yield, oil content, and fatty aci...

background: summer savory (satureja hortensis l.) is one of the most important medicinal and spice plants cultivated in many parts of the world. objective: a greenhouse experiment was conducted to study the effects of feso4 and citric acid application on the morphological traits and essential oil content and its component, gamma-terpinene in s. hortensis. methods: feso4 in four levels (0, 3, 4 ...

the present study was designed to determine the effects of the essential oil of laurusnobilis l. (lauraceae) and its three main components on α-glucosidase and reactive oxygenspecies scavenging activity. the chemical composition of the essential oil from laurus nobilisl. leaves was analyzed by gc/gc-ms and resulted in the identification of 29 compounds,representing 99.18% of the total oil. 1,8-...
