As a peculiar folk medicinal plant, Acanthopanax brachypus was widely used to treat various diseases in China. At present, however, there is not a good quality standard for its quality evaluation. In this study, on the basis of the validation tests of precision, stability and repeatability, the chromatographic fingerprint of A. brachypus was established by using gas chromatography (GC)-flame io...

Water-distilled essential oil from the aerial parts of Dipsacus japonicus Miq. (Dipsacaceae) at the flowering stage was analysed by gas chromatography-mass spectrometry (GC-MS). Forty-six compounds, accounting for 96.76% of the total oil, were identified and the main compounds of the essential oil were linalool (11.78%), trans-geraniol (8.58%), 1,8-cineole (7.91%), beta-caryophyllene (5.58%), a...

As part of our continuing efforts in the search for potential biologically active compounds from medicinal plants, we have isolated 18 compounds including two novel nitrogen containing diterpenes from extracts of the fruits of Vitex agnus-castus. These isolates, along with our previously obtained novel compound vitexlactam A (1), were evaluated for potential biological effects, including cancer...

The chemical constituents of the essential oil from the leaves of Gynura divaricata (L.) DC. were investigated by GC-FID and GC-MS. Seventeen compounds, representing 97.1 % of the chromatographical fraction of the oil, were detected. The major constituents, cubenol (65.7 %) and spathulenol (6.4 %), were isolated using column chromatography and identified by NMR and MS analysis. The antioxidant,...

The aim of this work is to investigate the in vitro cytotoxic and antibacterial effects of the essential oils of Aloysia citriodora Palau, harvested in different regions of Morocco. The chemical profile was established using gas chromatography-mass spectrometry analysis. The cytotoxic activity against P815, MCF7, and VERO cell lines as well as the normal human peripheral blood mononuclear cells...

Leishmaniasis and trypanosomiasis are globally widespread parasitic diseases which have been responsible for high mortality rates. Since drugs available for their treatment are highly hepatotoxic, nephrotoxic and cardiotoxic, adherence to therapy has been affected. Thus, the search for new, more effective and safer drugs for the treatment of these diseases is necessary. Natural products have st...

the essential oils of the aerial parts of a. armeniaca and a. incana , collected from arasbaran area (east azarbaijan province, iran) were extracted by hydrodistillation and analyzed by gc-ms. in total, 16 and 40 constituents were identified and quantified in the oils of a. armeniaca and a. incana representing 80.5% and 84.6% of the oils, respectively. the essential oil of a. armeniaca was main...

In Brazil, Aedes aegypti mosquito is the most frequent vector of some arboviruses, such as dengue, yellow fever, Zika and chikungunya. The use synthetic insecticides to combat this has been compromised due development resistant populations collateral damage caused nature. Essential oils (EO) have studied an alternative insecticide. Thus, objective work was do a review EOs from Caatinga biome pl...

The chemical composition of the essential oils of flower at the pre-flowering, full-flowering and post-flowering stage of A. annua was analyzed by GC and GC/MS and sixty-two components were identified. The main compounds in the pre-flowering oil were β-myrcene (37.71%), 1, 8-cineole (16.11%) and camphor (14.97%). The full-flowering oil contained predominantly caryophyllene (19.4%), germacrene D...
