α-Phellandrene (α-PA) is a component of dietary spices and herbs. The effect of α-PA on anticancer is unclear. This study aims to investigate the effects of α-PA on liver tumor cell death fate. Human liver tumor (J5) cells were incubated with α-PA and analyzed for cell cycle distribution, expression
Conobea scoparioides (Cham. & Schltdl.) Benth. (syn. Sphaerotheca scoparioides Cham. & Schldtl.) (Plantaginaceae), popularly known as "pataqueira", "vassourinha-do-brejo" and/or "hierba-de-sapo", is a popular medicinal plant used to treat leishmaniasis, pain and beriberi. In addition,
This study was undertaken to investigate the in vitro wound healing effects and the anti-inflammatory and antioxidant activities of terpinolene and α-phellandrene. The in vitro stimulatory effects on the proliferation and migration of fibroblasts were assessed using the scratch assay. The
Isolation of volatile and fixed oils from nutmeg have been obtained by supercritical fractioned extraction with carbon dioxide. Extraction experiments were carried out at pressures of 90 and 250 bar and temperature of 40 °C. The extraction step performed at 90 bar produced a volatile fraction mainly
Bioautography has been used as rapid and easy strategy to detect and identify bioactive fractions/molecules in the never before investigated Hedyosmum sprucei Solms (Chloranthaceae) essential oil (EO). The antioxidant activity, performed through DPPH bioautographic assay and spectrophotometric
The leaf essential oils of Zanthoxylum rhoifolium and Zanthoxylum setulosum (Rutaceae) from Monteverde, Costa Rica have been obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry. The principal constituents of Z. rhoifolium leaf oil were germacrene D (14.6%), limonene
Essential oils (EOs) from leaves and branches of Aniba parviflora (Meisn.) Mez were obtained by hydrodistillation and their chemical compositions determined by gas chromatography - mass spectrometry. Oxygenated sesquiterpenoids were the most representative compound class in both EOs (~ 40%).
BACKGROUND
Cancer has become a global public health problem and the search for new control measures is urgent. Investigation of plant products such as essential oils from Monodora myristica, Xylopia aethiopica and Xylopia parviflora might lead to new anticancer therapy. In this study, we have
OBJECTIVE
The bioactivities of Santolina corsica Jord. & Fourr. n-hexane (EHS) and methanol (EMS) extracts were evaluated in relation to their chemical profile.
METHODS
EHS and EMS were analysed by gas chromatography-mass spectrometry () and high performance liquid chromatography-diode array
BACKGROUND
Solanum erianthum D. Don and Solanum macranthum Dunal (Solanaceae) are widely used in traditional medicine. The leaves act as an abortifacient and in particular to treat leucorrhoea, sores, and skin irritations.
OBJECTIVE
This study was undertaken to characterize the volatile constituents
BACKGROUND
The aim of this work was to study the constituents and cytotoxicity of the essential oils from the fruits of Angelica archangelica growing in Iceland.
METHODS
Three samples of essential oils were prepared by steam distillation. Their composition was established with GC/MS. The effects of
The present study was carried to observe the phytochemical profile of aromatic constituents of Artemisia gmelinni essential oil using GC-FID, GC-MS and 13C NMR and to evalute anticancer and antioxidant activities. Twenty chemical constituents were detected from EO accounting 92.05% of
The essential oil from the leaves of Phoebe formosana from Taiwan was isolated using hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. Seventy-one compounds were identified, representing 100% of the oil. The main components identified were a-humulene (16.8%),
Two novel tricyclic spirolactones bearing long linear alkyl chains, yaoshanenolides A (1) and B (2), formed by Diels-Alder[4 + 2] cycloaddition of a molecule of each butenolide with β-phellandrene, were isolated from the bark of Machilus yaoshansis. Their structures and absolute configurations were
Myrica gale L. (Myricaceae), a native plant from Canada used in traditional medicine, was extracted by hydrodistillation and the oil was collected after 30 and 60 min. The chemical composition of these two extracts was determined using GC-MS analysis. We identified 53 components and myrcene
