Ocimum basilicum is a valuable source of bioactive metabolites with high preventive and therapeutic effectiveness. Here we aimed to investigate the effect phenological stages (vegetative flowering stages) on essential oil composition biological activities two varieties O. (Fino Verde variety Genovese varieties). To this end, level oils, flavonoids phenols, as well antioxidant antifungal were me...

Mikania laevigata leaves are used worldwide as herbal medicines. Our study investigates the production differences among three different genotypes of this herb: genotypes’ influence on essential oil yield, chemical composition, and plant tissues involved in secretion compounds produced by leaves. The performed analysis during summer winter seasons. Plants were grown under an organic cultivation...

The hydro-distilled essential oil from the fresh aerial part of Orchidantha vietnamica K. Larsen collected Lamdong-Vietnam was analyzed by GC-FID (Gas Chromatography-Flame Ionization Detection) and GC-MS Chromatography-Mass Spectroscopy) for first time. characterized presence volatile compounds type terpenoids, in which oxygenated monoterpenes (30.04 %) sesquiterpene hydrocarbons (37.32 are maj...

The purpose of this systematic review was to identify the available literature on essential oil from species genus Cordia. This study followed Preferred Reporting Items for Systematic Reviews. search conducted four databases: LILACS, PubMed, Science Direct, and Scopus until June 5th, 2020, with no time or language restrictions. Sixty out 1,333 initially gathered studies fit inclusion criteria a...

Objective(s):Various species of genus Trigonella are important from medical and culinary points of view. The essential oil of Trigonella torbatejamensis Ranjbar as an endemic plant in Iran has not been studied previously. The essential oil of this plant was analyzed by different methods for identification of its components. Materials and Methods: The essential oil composition of aerial parts o...

Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal microorganisms and cytotoxic properties. EOs of Kielmeyera coriacea Mart. & Zucc. were analyzed by gas chromatography coupled to mass spectrometry (GC-MS). The EO from leaves is rich in sesquiterpenes hydrocarbons and oxygenated sesquiterpenes. The three major compounds identified were germa...

Natural products represent a source of biologically active molecules that have an important role in drug discovery. The aromatic plant Blepharocalyx salicifolius has a diverse chemical constitution but the biological activities of its essential oils have not been thoroughly investigated. The aims of this paper were to evaluate in vitro cytotoxic, antifungal and antibacterial activities of an es...

Helichrysum gymnocephalum essential oil (EO) was prepared by hydrodistillation of its leaves and characterized by GC-MS and quantified by GC-FID. Twenty three compounds were identified. 1,8-Cineole (47.4%), bicyclosesquiphellandrene (5.6%), γ-curcumene (5.6%), α-amorphene (5.1%) and bicyclogermacrene (5%) were the main components. Our results confirmed the important chemical variability of H. g...

BACKGROUND Rhaphiodon echinus is a weed plant used in the Brazilian folk medicinal for the treatment of infectious diseases. In this study, the essential oil of R. echinus leaf was investigated for its antimicrobial properties. METHODS The chemical constituents of the essential oil were characterized by GC-MS. The antimicrobial properties were determined by studying by the microdilution metho...

Lippia dulcis is a sweet-tasting, woody herb but the sweetness is often mixed with a camphorous taste. Lippia dulcis oil from Brazil was found to be low in camphor (trace), whereas the oil from Mexico had considerable camphor (33.9%). The Lippia oil from Brazil was high in 6-methyl-5-hepten-2-one (10.5%), α-copaene (8.6%), (E)-caryophyllene (10.6%), bicyclogermacrene (6.6%), δ-cadinene (7.2%), ...
