in this research, the effect of foliar spraying times and different levels of farmax® nano fertilizer on morphological characteristic and dry and fresh flower yield, essential oil and chamazulene percentage of chamomile (matricaria recutita l.) cv. bodegold was studied. the experiment was factorial in the bacic of randomized complete blocked design (rcbd) with eight treatment and four replicati...

conclusions according to antioxidant activity outcomes, the amount of ic50s of aqueous extracts of flower and stem and also butylated hydroxyl toluene (bht) as standard were 232.34, 63.25 and 45.59 ppm respectively. ultimately, it was highlighted that antioxidant activity of aqueous extract of flower was weaker than stem. results sixty one compounds were identified in the essential oil of the f...

Pollination contributes to an estimated one third of global food production, through both the improvement of the yield and the quality of crops. Volatile compounds emitted by crop flowers mediate plant-pollinator interactions, but differences between crop varieties are still little explored. We investigated whether the visitation of crop flowers is determined by variety-specific flower volatile...

Anthemis nobilis (Roman chamomile) flower extract, anthemis nobilis flower oil, anthemis nobilis flower powder, and anthemis nobilis flower water are ingredients that function as fragrance ingredients and skin-conditioning agents in cosmetic products. These ingredients are being used at concentrations up to 10% (anthemis nobilis flower water) in cosmetic products. The available data indicate th...

pumpkin is one the most important cultivated medicinal plants. because of high quality oil it uses as edible and herbal medicine. to find out the effects of different rates of pelleted animal manure and urea levels and some micronutrients on morphophysiological characteristics and oil yield of medicinal pumpkin, a split plot experiment based on rcbd with three replicates was conducted at the re...

This paper reports a methodology for fast analysis of two important antioxidants: tyrosol and oleuropein in real samples of alimentary oils by using a ready-to-use portable microfluidic system (MicruX ® iHVStat) based on microchips electrophoresis with electrochemical detection. The portable system integrates for the first time a high voltage power supply and a bipotentiostat for using microflu...

salvia genus belongs to lamiaceae family that was used in ancient and its application in culinary, flavor cosmetics, food and drinking industries is important. in the present study to assess compatibility of salvia sclarea to field condition and determine its potential for medicinal and ornamental applications, wild seed were cultured in pots. after initial growth, seedlings at 6-8 leaf stage t...

We report the chemopreventive activity of Acacia nilotica (Linn.) gum, flower and leaf aqueous extracts, on 7,12-dimethylbenz(a)anthracene (DMBA) induced skin papillomagenesis in male Swiss albino mice. Animals were divided into following groups: Group I (Controls) given DMBA and croton oil, with no extract ; Group II (treatment) animals treated with Acacia nilotica gum (Group II-a) (800 mg/kg ...

The essential oils of two Alpinia species, ie. A. hainanensis and A. katsumadai, from Hainan Island, China were analyzed by using GC-MS. The major constituents in the leaf oil of A. hainanensis were ocimene (27.4%), beta-pinene (10.1%), 9-octadecenoic acid (6.5%), n-hexadecanoic acid (5.8%), 9,12-octadecadienoic acid (5.4%), and terpinen (4.3%). The oil constituents obtained from the flowers of...

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...
