essential oils are considered as very complex natural mixtures containing numerous components at quite various concentrations. lythrum salicaria has not been previously subjected to examination of its volatile oil. the present study was carried out to evaluate the essential oil composition of the flowering aerial parts of the plant by using conventionally hydro-distillation (hd) and microwave a...

The constituents of honey's volatile compounds depend on the nectar source and differ depending on the place of origin. To date, the volatile constituents of Tualang honey have never been investigated. The objective of this study was to analyze the volatile compounds in local Malaysian Tualang honey. A continuous extraction of Tualang honey using five organic solvents was carried out starting f...

BACKGROUND Artemisia aerial parts are well known for antimicrobial activities including anti malaria. OBJECTIVES This study was carried out to evaluate the antimicrobial activity and chemical composition of essential oil from the seeds of Artemisia aucheri Boiss (Asteraceae). MATERIALS AND METHODS Essential oil was extracted from the powdered seeds of Artemisia aucheri by hydrodistillation....

The present study was designed to identify the chemical constituents of the methanolic extract of Curcuma longa L. rhizomes and their inhibitory effect on a hepatoma cell line. The methanolic extract was subjected to GC-MS analysis to identify the volatile constituents and the other part of the same extract was subjected to liquid column chromatographic separation to isolate curcumin. The inhib...

Abstract—Boerhavia diffusa L. is a plant which is extensively used in folk medicine and little attention has been given to the characterization of secondary metabolites other than rotenoids and alkaloids. The present study was carried out to identify the phytochemical components of the plant using ethanolic, chloroform, petroleum ether and water extracts and to analyse the volatile composition ...

The present research was planned to characterize the aroma composition of important members of the Lamiaceae family such as Salvia officinalis, Lavandula angustifolia and Mentha asiatica. Aroma components of the S. officinalis, L. angustifolia and M. asiatica were extracted with the purge and trap technique with dichloromethane and analyzed with the gas chromatography-mass spectrometry (GC-MS) ...

In lizards, the epidermal glands of the femoral and precloacal regions are involved in the production of semiochemicals. In addition to its femoral glands, the giant girdled lizard, or sungazer, Cordylus giganteus, which is endemic to South Africa, has generation glands as an additional potential source of semiochemicals. These epidermal glands are described as glandular scales that overlay the...

Introduction:  Plants are a rich source of phenolic compounds that as natural antioxidants prevent oxidative stress and are very good for health. Ziziphora clinopodioides belongs to Lamiaceae family and its aerial parts are used in pharmaceutical and food industries. It is effective in the treatment of heart disorders, cold, depression, diarrhea, coughing, migraine and...

Sádecká J. (2010): Influence of two sterilisation ways, gamma-irradiation and heat treatment, on the volatiles of black pepper (Piper nigrum L.). Czech J. Food Sci., 28: 44–52. The objective of this study was to investigate and compare the effects of ionising irradiation with different doses of gamma-rays (5 kGy, 10 kGy, and 30 kGy) versus the effect of heat sterilisation (dry steam, 130°C, 3 m...
