An efficient microwave-assisted simultaneous distillation and extraction (MA-SDE) method has been developed for the separation of polysaccharides and essential oil from Taxus chinensis var. mairei. The key operating parameters for MA-SDE were optimized by single factor and central composite design experiments, and the optimal conditions were found to include a particle size of 60–80 mesh, liqui...

The volatile oil obtained from the cones of Cupressus funebris by hydrodistillation was subjected to anti-inflammatory activity using carrageenan induced paw oedema model using albino mice, Diclofenac sodium was used as standard drug (25 mg/kg body weight, p.o.). The volatile oil (100 mg/kg body weight, p.o.) showed significant anti inflammatory activity.

Piper hispidinervum (C. DC.), Piperaceae, is a promising source of sassafras oil, the source of safrol, currently derived from endangered plants of the Lauraceae such as Ocotea pretios Ness (Mez.), Cinamomum petrophilum, C. mollissimum, and Sassafras albidum Nutt. The essential oil of P. hispidinervum contains high levels (83–93%) of safrole in leaves which can be easily extracted by hydrodisti...

Abstract Virgin olive oil processing results in a large amount of biomass (leaves, pomace, stones and wastewater) during harvesting, pruning production. In recent years, these by-products have been studied as possible sources bioactive compounds, several techniques developed, including microwave, ultrasound, subcritical extraction, high hydrostatic pressure, pulsed electric field, high-voltage ...

Dendranthema indicum var. aromaticum, which is an aromatic plant with a strong and special fragrance throughout the whole plant, is used for the treatment of colds and headaches, and as a mosquito repellant in Shennongjia, Hubei province, China. To analyze the composition of the essential oil from this medicinal herb, we developed a gas chromatography-mass Spectrometry (GC-MS) method including ...

the aim of this study was to investigate the stachys turcomanica phytochemical compounds, antimicrobial and antioxidant activity of methanolic extract. the volatile constituents from the aerial parts of stachys turcomanica growing wild in iran were obtained by hydrodistillation and analyzed by gc and gc-ms. in the gc-ms analysis, forty-six components representing 81.1% of the oil were identifie...

Plant extracts are being studied in the development of novel edible food coatings. The antioxidant and antimicrobial compounds that naturally occur some plants key substances contribute to preserving quality. Besides plant material, method utilized produce extract influences its chemical preservative characteristics. In general, hydrodistillation products (essential oils) well recognized for co...

The search for new insecticides to control dengue fever, chikungunya, and Zika vectors has gained relevance in the past decades. The aim of the present study was to evaluate the larvicidal action of essential oils (EOs) from Thymus vulgaris, Salvia officinalis, Lippia origanoides, Eucalyptus globulus, Cymbopogon nardus, Cymbopogon martinii, Lippia alba, Pelargonium graveolens, Turnera diffusa, ...

This study focused on five different subspecies of Portuguese Daucus carota L., to identify the main compounds in essential oils umbels from each subspecies. The isolation was performed by hydrodistillation methods followed further composition analysis gas chromatography-mass spectrometry, ultimately demonstrating that had major compounds. concluded found subsp. maritimus were geranyl acetate, ...
