herbal water is referred to the liquid obtained from the distillation of medicinal plants. different parts of plants, such as flowers, fruits, leaves, seeds and roots have long been used to produce herbal waters. herbal waters are used as dietary supplements and alternative medicine and are commonly used for flavoring in baking. previous studies focused on the non-volatile constituents of herbs...
There is a few reported about the volatile oil component of petal, herbal and component of seed oil of borage. This research worked carried out for analysis and identification the volatile oil in herbals, petals, and seed oil compositions of Borago officinalis L. in Lorestan province. Material and methods: Extraction of essential oil from petals carried out using steam distillation by Cleveng...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
background: moringa peregrina (forssk.) fiori. is a small tree, which grows in south east of iran. the shoot and root of m. peregrina contain volatile oil which has several isothiocyanates. objective: to study the effect of salinity on volatile constituents of root and shoot of m. peregrina. methods: the experiment was conducted on randomized complete blocks design (rcbd) with 8 treatments and ...

The aim of this study was to explore the volatile compounds of hind leg, foreleg, abdomen and Longissimus dorsi in both male and female Hyla rabbit meat by solid phase microextraction tandem with gas chromatography mass spectrometry, and to seek out the key odorants via calculating the odor activity value and principal component analysis. Cluster analysis is used to study the flavor pattern dif...
"Padrón-type" peppers are a small variety of Capsicum annuum cultivated mainly in Galicia, Spain. To compare the effects of freezing and freeze-drying on the volatile components of Padrón-type peppers, preserved samples are analyzed by means of dynamic headspace sampling on an adsorbent followed by microwave desorption into a gas chromatograph equipped with a mass spectrometric detector. Sixty-...
Chemical compositions, volatile compounds and sensory property of Kapi produced from two shrimp species, Acetes vulgaris and Macrobrachium lanchesteri, were comparatively determined. Kapi produced from M. lanchesteri (KM) had the higher protein content but lower fat content, compared with that from A. vulgaris (KA) (p < 0.05). However, KA showed higher browning intensity (A420) and fluorescence...
Anti-diabetic capacity of Curcuma longa volatile oil in terms of its ability to inhibit glucosidase activities was evaluated. Turmeric volatile oils inhibited glucosidase enzymes more effectively than the reference standard drug acarbose. Drying of rhizomes was found to enhance α-glucosidase (IC₅₀ = 1.32-0.38 μg/ml) and α-amylase (IC₅₀ = 64.7-34.3 μg/ml) inhibitory capacities of volatile oils. ...
