The chemical components of the leaf oil of Litsea acutivena Hayata collected from Pu Huong Natural Reserve, Nghe An Province, Vietnam, were identified by co-chromatography with authentic samples, gas chromatography/mass spectrometry (GC/MS) and linear retention indices. The significant compounds of L. acutivena were α-phellandrene (30.4%) and α-pinene (14.2%). The constituents of essential oil of L. acutivena from Vietnam are being reported for the first time.

Essential oils have been largely employed for human need due to their antibacterial, antifungal and insecticidal activities. At present, approximately 3000 essential oils are known, 300 of which are commercially important. Essential oils or some of their components are used in perfumes and make-up products, sanitary products, dentistry, agriculture, as food preservers and additives, and as natural remedies. The essential oil compositions of Malaysian Lauraceae family have been investigated for m...

Pogostemon cablin Benth. (patchouli) is an important herb which possesses many therapeutic properties and is widely used in the fragrance industries. In traditional medicinal practices, it is used to treat colds, headaches, fever, nausea, vomiting, diarrhea, abdominal pain, insect and snake bites. In aromatherapy, patchouli oil is used to relieve depression, stress, calm nerves, control appetite and to improve sexual interest. Till now more than 140 compounds, including terpenoids, phytosterols,...

AbstractIn this paper, the compositional pattern of essential oils from five plants in the genus Litsea (Lauraceae family) cultivated in Vietnam, were being reported. The air-dried plant materials were hydrodistilled and the oils were analysed by Gas chromatography-flame ionization detector (GC-FID) and Gas chromatography coupled with Mass spectrometry (GC-MS). The leaf oil of Litsea helferi Hook.f., was rich in limonene (17.5 %), β-caryophyllene (14.2 %), bicyclogermacrene (13.1 %), bicycloelem...

β-caryophyllene is a sesquiterpene widely distributed in essential oils of various plants. Several biological activities are attributed to β-caryophyllene, such as anti-inflammatory, antibiotic, antioxidant, anticarcinogenic and local anaesthetic activities. In this work, the potentiating effect of β-caryophyllene on the anticancer activity of o-humulene, isocaryophyllene and paclitaxel against MCF-7, DLD-1 and L-929 human tumour cell lines was evaluated. A non-cytotoxic concentration of /3-cary...

The psychoactive cannabinoids from Cannabis sativa L. and the arachidonic acid-derived endocannabinoids are nonselective natural ligands for cannabinoid receptor type 1 (CB(1)) and CB(2) receptors. Although the CB(1) receptor is responsible for the psychomodulatory effects, activation of the CB(2) receptor is a potential therapeutic strategy for the treatment of inflammation, pain, atherosclerosis, and osteoporosis. Here, we report that the widespread plant volatile (E)-beta-caryophyllene [(E)-B...

Abstract Since the middle ages, essential oils have been widely used for bactericidal, virucidal, fungicidal, antiparasitical, insecticidal, medicinal and cosmetic applications, especially nowadays in pharmaceutical, sanitary, cosmetic, agricultural and food industries. Because of the mode of extraction, mostly by distillation from aromatic plants, they contain a variety of volatile molecules such as terpenes and terpenoids, phenol-derived aromatic components and aliphatic components. In vitro p...

Abtracst The volatile components of the leaf oil of Litsea euosma J.J.Sm. from the Nghean province, Vietnam were analyzed by Capillary GC, GC/MS as well as in some cases by background subtraction of coeluting compounds. 41 constituents representing (96.5%) of the oil were identified, of which α-pinene (11.8%), sabinene (24.9%) and β-pinene (14.0%) were major components. Lesser amounts of β-myrcene (2.1%), limonene (5.0%), (Z), and (E)-β-ocimene (4.4% and 3.1%), citronellal (2.0%) and germacrene ...

Abstract A method for the screening of antioxidant activity is reported as a decolorization assay applicable to both lipophilic and hydrophilic antioxidants, including flavonoids, hydroxycinnamates, carotenoids, and plasma antioxidants. The pre-formed radical monocation of 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS •+ ) is generated by oxidation of ABTS with potassium persulfate and is reduced in the presence of such hydrogen-donating antioxidants. The influences of both the co...
