Many herbal medicines pertain characteristic odour which indicates the volatility of some compositions. Most of the volatiles constituents have low molecular weight, typically, monoterpenes, sesquiterpenes and phenylpropanes and their oxygenated derivatives (Harnone, 1998). Some herbs contain high content of volatile oils from which the oil themseleves are used as drugs, for example eucalyptus ...

Abstract Clinopodium serpyllifolium is a perennial medicinal plant generally used as herbal tea in folk medicine. Leaves of C. from the representative exemplars Newe Ya’ar living germplasm collection were analyzed for their polyphenolic and volatiles composition, tested antioxidant activity. The oxygenated monoterpenes pulegone (10.4–50.6%), piperitenone oxide (3.2–28.6%), (0.9–14.6%), trans -p...

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: This study aimed to examine the composition of essential oil (EO) of A. millefolium aerial parts wild plant grown in France and evaluate its antioxidant, antibacterial, and antifungal activities. Methods: GC-MS was used to identify the chemical composition of EO. Antioxidant activity (AA) of EO was evaluated by Oxipres method. Antimicrobial activity of EO was evaluated by Agar-well ...

The effects of different polyphenol-containing beverages on Fe absorption from a bread meal were estimated in adult human subjects from the erythrocyte incorporation of radio-Fe. The test beverages contained different polyphenol structures and were rich in either phenolic acids (chlorogenic acid in coffee), monomeric flavonoids (herb teas, camomile (Matricaria recutita L.), vervain (Verbena off...

BACKGROUND: The use of antibiotics as feed additive in animal feeds due to the appearance of residues in milk and meat and their effects on human health has restricted. Two of essential oils with high potential for use in ruminant diet are Mentha piperita (peppermint) and Mentha pulegium (pennyroyal) essential oil. OBJECTIVE: This study was conducted to investigate the effects of essential oils...

The essential oil of Salvia aegyptiaca was analysed by GC/ MS technique. Eighteen compounds were identified. It was found that the essential oil comprises 40% terpenoidal constituents, opposite to 32% fat derivatives. The major terpenoidal component was 1(10)aristolene (19.3%). From the non-volatile matter, β-amyrin, lupeol, β-sitosterol, stigmasterol, β-sitosterol-β-D-glucopyranoside and stigm...
