Chemical constituents of essential oils from three Vietnamese species of Pinus

This paper reports the chemical composition of essential oils obtained from Pinus dalatensis Ferré, Pinus kwangtungensis Chun ex. Tsiang and Pinus armandii subsp. xuannhaensis L.K. Phan. The oils were studied by gas chromatograpgy (GC) and gas chromatography coupled to mass spectrometry (GC-MS). The ma...

Phthalate contamination of some plants and herbal products

Phthalate derivatives cause a number of risks to human health and the environment. Essential oil and volatile fractions of some vegetables and herbal products were extracted by hydrodistillation and percolation methods to analyze using gas chromatography and mass spectrometry (GC-MS) for evaluation of ph...

Antifungal activity of Gallesia integrifolia fruit essential oil

Braz. j. microbiol; 49 (supl.1), 2018
ABSTRACT Gallesia integrifolia (Phytolaccaceae) is native to Brazil and has a strong alliaceous odor. The objective of this study was to identify the chemical composition of G. integrifolia fruit essential oil and evaluate fungicidal activity against the main food-borne diseases and food spoilage fungi. ...

Antifungal activity of the essential oil of cymbopogon citratus (DC) stapf: an in vitro study

J. oral res. (Impresa); 6 (12), 2017
Aim. to evaluate the antifungal potential of the essential oil of cymbopogon citratus by determining the minimum inhibitory concentration (MIC) and the minimum fungicidal concentration (MFC) for candida albicans (ATCC 90029), candida albicans (CBS 562), candida tropicalis (ATCC 705) and candida tropicali...

Repellent activity of essential oils extracted from five Artemisia species against Tribolium castaneum (Coleoptera: Tenebrionidae)

Artemisia genus (family Asteraceae) has been widely used as medicines and cosmetic. The chemical compositions of essential oils extracted from five Artemisia species (A. anethoides, A. giraldii, A. roxburghiana, A. rubripes and A. sacrorum) were analyzed and the repellent activities of five essential oil...

Chemical composition of essential oil from leaves of Ocotea limae Vattimo Gil. and Ocotea gardneri (Meisn. ) Mez. growing wild in Atlantic forest of North-Eastern Brazil

Essential oils from leaves of Ocotea limae and Ocotea gardneri species were analyzed by GC-FID and GC-MS. The analysis revealed the presence of 48 components accounting for 98.1 ± 1.3% e 98.0 ± 0.5% of the essential oils from the O. limae and O. gardneri, respectively. The oils were characterized by hi...

Chemical constituents and insecticidal activity of essential oil of Paullinia pinnata L (Sapindaceae)

The chemical constituents and insecticidal activity of essential oil obtained by hydrodistillation of the leaves of Paullinia pinnata Linn (Sapindaceae) are being reported. The essential oil were analysed by using gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC-MS). Diff...

Essential oil composition, carotenoid profile, antioxidant and antimicrobial activities of the parasitic plant Cuscuta mitraeformis

The chemical composition of the essential oil and carotenoid content of the parasitic plant Cuscuta mitraeformis are described for the first time. The essential oil was analyzed by GC-FID and GC-MS revealing nonanal (24.6%) as the main constituent followed by thymol (16.5%) and eugenol (7.5%). The total ...

Uses of hazardous medicinal plants: composition of the essential oil of Clinopodium gilliesii (Benth. ) Kuntze (Lamiaceae), collected in Chile

Clinopodium gilliesii (Benth.) Kuntze, harvested in the Chilean highlands, contains a surprising 93.87% of the toxic monoterpene pulegone in the essential oil. These results show remarkable differences with studies of the same species carried out in Argentina and Peru. These dissimilarities in the monote...

Cytotoxic effects of the essential oil from leaves of Casearia sylvestris Sw. (Salicaceae) and its nanoemulsion on A549 tumor cell line

Extracts from leaves of C. sylvestris have cytotoxic effect in different tumor cell lines, possibly due to clerodane type diterpenes (casearins). On the other hand, there are few studies related to the antitumor activity of the essential oils from this species. This work evaluated for the first time the ...
