Commercial plant essential oils obtained from 11 Myrtaceae plant species were tested for their fumigant antifungal activity against Aspergillus ochraceus, A. flavus, and A. niger. Essential oils extracted from Leptospermum petersonii at air concentrations of 56 × 10(-3) mg/mL and 28 × 10(-3) mg/mL completely inhibited the growth of the three Aspergillus species. However, at an air concentration...

The volatile compounds obtained from the different organs of Houttuynia cordata (Saururaceae) and Litsea cubeba (Lauraceae) were analyzed by Gas Chromatography/Mass Spectrometry (GC/MS), Headspace Solid Phase Micro Extraction-Gas Chromatography/Mass Spectrometry (HS-SPME-GC/MS), and GC/olfactometry (GC/O). The major component of all parts of H. cordata is assigned as 4-tridecanone. Each organ p...

The orange-yellow and colorless essential oils with respective yields of 1.54% 3.59% were extracted from the dry leaves Cymbopogoncitratus (DC.) Stapf Eucalyptus citriodora Hook. collected south Brazzaville. Analysis by gas chromatography (GC) coupled mass spectrometry (GC/MS) allowed identification fifteen (15) eight (8) constituents representing (96.25%) (98.46%) total respectively. oil consi...

Introduction & Aim: The aim of this study was evaluating effect of methanol and ethanol foliar application as a new and safe technology in plant production on lemon balm’s (Melissa officinalis L.) volatile oil components. Experimental: Experimental carried out based on a Randomized Complete Block Design (RCBD) with fifteen treatments and three replications in the experimental field of...

Single-strength orange juice was irradiated with 0, 0.89, 2.24, 4.23, and 8.71 gGy of gamma radiation at 5 degrees C and then stored at 7 degrees C for 21 days. Volatile compounds, isolated by solid-phase microextraction, were separated and identified using a gas chromatograph equipped with a mass selective detector. The majority of the volatile compounds were terpenes, and the most abundant vo...

Aromatic plants are rich in essential oils with considerable antimicrobial properties.The aim of this study was to investigate chemical composition, antimicrobial activity and antioxidant properties of Melissa officinalis and Deracocephalum moldavica essential oils (EOs). The identification of chemical constituents of the EOs was carried out using gas chromato-graphy-mass spec...

Environmental stress has a major influence on the growth and quality of medicinal plants. More than half agricultural land worldwide suffers from lack water. In this study, we estimated effect different irrigation intervals growth, yield, essential oil content as well their main compounds lemongrass, Cymbopogon citratus. The objective was to test how much consumption can be lowered without sign...

Background: Lemon verbena (Lippia citriodora H.B.K.) is an aromatic and medicinal plant of family Verbenaceae, which cultivated in the North region of Iran. Objective: This comparative study was carried out on essential oil content and composition of Lippia citriodora H.B.K. from micro-propagated and rooted apical stem cutting plantlets. Methods: The micro-propagated plantlets were obtained ...
