Medicinal plants are quite popular in the medicine development process because they contain bioactive chemicals. Traditional has made extensive use of Crataegus orientalis L., which also significant biological effects. In this study, essential oils (EOs) C. var. collected from Tokat-Türkiye were isolated by hydrodistillation. Chemical constituents detected GC-MS and benzaldehyde (%52.75), α-ter...

Betonica bulgarica is an endemic species distributed in Bulgaria. The chemical composition of the essential oil analysed by GC–MS (Gas chromatography–mass spectrometry) and content trace elements ICP–MS (Inductively coupled plasma mass were determined. Additionally, a study on types distribution trichomes was done using microscope with camera. characterized high concentration sesquiterpene hydr...

The study investigated the phytochemical and essential oil compositions of Piper umbellatum Linn leaves. leaves were detached from stalk washed carefully under running tap water, air dried at room temperature (20-25 ) for 14 days. ground into a fine powder using grinding mill. Phytochemical oils composition analyzed GC/MS. revealed higher concentrations phenolic acids (434.95164 mg/100 g), tann...

The floral aroma, sometimes known as an incorporeal gift of flowers, is one the primary ornamental features plants. Flowers genus Tilia are fragrant and have great value for development utilization. In this study, first time, headspace solid-phase microextraction (HS-SPME) gas chromatography-mass spectrometry (GC-MS) combined with chemometrics were used to analyze dynamic variations scent compo...

UNLABELLED BACKGROUND The biological importance of members of genus Ferula promoted us to investigate the leaves of Ferula vesceritensis Coss et Dur. (endemic plant) previously not investigated. This study presents the chemical composition and antibacterial activities of the hydrodistilled oils. RESULTS Volatile components of the leaves of F. vesceritensis have been studied by gas chromato...

GC-MS analysis identified forty seven and fourteen components in oils extracted using HD and in the volatile fractions extracted using HSE, respectively. eudesm-7(11) en-4-ol (28.46%), α-terpinyl acetate (12%), germacrene D-4-ol(7.3%), 1,8-cineole (6.22%), δ-cadinene (6.49%), bicyclogermacrene (5.20%) and α-cadinol (5.06%) were recorded as the main components of the essential oil and The major ...

The essential oils obtained by steam distillation from needles of six China endemic Pinus taxa (P. tabulaeformis, P. tabulaeformis f. shekanensis, P. tabulaeformis var. mukdensis, P. tabulaeformis var. umbraculifera, P. henryi and P. massoniana) were analysed by GC/MS. A total of 72 components were separated and identified by GC/MS from the six taxa. The major constituents of the essential oils...

Essential oils composition of the aerial parts of Artemisia nilagirica (Clarke) Pamp. var. septentrionalis Pamp. in different seasons viz. spring, summer, rainy, autumn and winter seasons under foot hills agroclimatic conditions of western Himalaya were analyzed and compared by GC–FID and GC–MS. Essential oils were mainly composed of monoterpenoids (59.0%-77.3%) and sesquiterpenoids (15.7%-31.6...
