The essential oil obtained from the fresh leaves of Zanthoxylum alatum was analysed by gas chromatography/mass spectrometry (GC/MS). Fourteen components were identified, and linalool (30.58%), 2-decanone (20.85%), β -fenchol (9.43%), 2-tridecanone (8.86%), β -phellandrene (5.99%), Sabinene (4.82%), and α -pinene (4.11%) were the main components. The EO and methanolic extract of Z. alatum exhibi...

Zanthoxylum limonella (Dennst.) Alston. (Rutaceae) or Ma-khwaen is one of the medicinal plants in Thai traditional medicine. To investigate the pharmacognostic specifications and chemical constituents of Z. limonella fruits and seeds. Fruits and seeds of Z. limonella were collected from 15 sources throughout Thailand; then examined the pharmacognostic specification following WHO guideline of qu...

In this study, Angelica dahurica and Angelica pubescentis root essential oils were investigated as pest management perspectives, and root samples were also analyzed genetically using the nuclear ribosomal internal transcribed spacer (ITS) region as a DNA barcode marker. A. pubescentis root essential oil demonstrated weak antifungal activity against Colletotrichum acutatum, Colletotrichum fragar...

The essential oils associated with the flowers of Tithonia diversifolia (Hemsl.) A. Gray were extracted and characterized via hydrodistillation and Gas Chromatography. Hydrodistillation was done in an all-glass Clevenger-type apparatus. The extracts from the hydrodistillation were subjected to gas chromatography where the components of the essential oils were separated based on their molecular ...

A number of essential oils derived from plants are claimed to have several medicinal functions, including anti-cancer and anti-inflammation effects. However, the chemical composition and biological activities of flower-derived components have not been sufficiently characterized. Therefore, we investigated the composition of essential oils from Hallabong flower [(Citrus unshiu Marcov × Citrus si...

The secondary organic aerosol (SOA) mass yields from NO3 oxidation of a series of biogenic volatile organic compounds (BVOCs), consisting of five monoterpenes and one sesquiterpene (α-pinene, β-pinene, Δ-3-carene, limonene, sabinene, and β-caryophyllene), were investigated in a series of continuous flow experiments in a 10 m(3) indoor Teflon chamber. By making in situ measurements of the nitrat...

Zanthoxylum nitidum (Roxb.) DC is a traditional Vietnamese medicine to treat coughs, stomachache, toothache, blood stagnation, and sore throats. The essential oils (EOs) of the leaves, fruits, stems this plant were extracted by hydrodistillation subjected analysis gas chromatography (GC)-flame ionization detector (FID) GC-mass spectrometry (MS). isolated EOs then evaluated in terms their antimi...

The aim of the present work was to study bioactivity lemon, orange, and grapefruit peel essential oils (EOs) obtained from Argentinian plantations on different agronomically important insect fungal species. chemical profile EOs determined by Gas Chromatography-Mass Spectrometry (GC/MS); insecticidal activity studied through contact fumigant assays; antifungal evaluated with tests. Orange EO mos...

The orange tree (Citrus sinensis) is a species of fruit shrubs the Rutaceae family. Essential oils from citrus peels are widely used in various agro-food and pharmaceutical preparations hence they must be recovered using green extraction methods. In this study, we compare efficiency five techniques (conventional hydro-distillation (HD), Salt-assisted by HD (S-HD), Ultrasound-assisted (US-HD), E...

Artemisia afra is a medicinal plant with antimicrobial activities, known to treat tuberculosis, measles, cough, and influenza. In consequence, its applications have increasingly become pivotal control various microbes which cause different diseases. This study therefore, evaluated the chemical composition antifungal activity of A. essential oil. The extraction oil was done using steam distillat...
