Discrimination of Pure and Mixture Agarwood Oils via Electronic Nose Coupled with k-NN kfold Classifier
Publication date: 2016 Source:Procedia Chemistry, Volume 20 Author(s): Sahrim Lias, Nor Azah Mohamad Ali, Mailina Jamil, Abdul Majid Jalil, Mohd Fadhli Othman Agarwood oils are extracted from low grade agarwood chips which are commonly processed via distillation. They can be obtained from various Aquilaria species such as A. malaccensis, A. hirta and A. crassna. This viscous oil is called as pure agarwood essential oil (100% of extracted material). Commonly, the oils are releasing long-lasting woody, warm and smoky scent due to slow release when applied to the skin. The blending of a small amount of this precious ag...

Essential Oils, Part IV: Contact Allergy.
Abstract
Nearly 80 essential oils (including 2 jasmine absolutes) have caused contact allergy. Fifty-five of these have been tested in consecutive patients suspected of contact dermatitis, and nine (laurel, turpentine, orange, tea tree, citronella, ylang-ylang, sandalwood, clove, and costus root) showed greater than 2% positive patch test reactions. Relevance data are generally missing or inadequate. Most reactions are caused by application of pure oils or high-concentration products. The clinical picture depends on the responsible product. Occupational contact dermatitis may occur in professionals perform...

Characterization of radicals arising from oxidation of commercially-important essential oils.
Authors: Mori HM, Iwahashi H
Abstract
Inappropriate use of essential oils may entail risks to human health due to mutational events, carcinogenic effects, genetic damages and sensitizing effect caused by generation of reactive oxygen species. In order to detect radicals that are expected to form during their oxidation, we measured the electron spin resonance (ESR) spectra of a standard reaction mixture (I) containing 25 μM flavin mononucleotide, 0.018% several essential oils (or 0.015% geraniol), 1.9 M acetonitrile, 20 mM phosphate buffer (pH 7.4), 0.1 M α-(4-pyridyl-1-oxide)-N-tert-butylnitrone (4...

Essential Oils, Part I: Introduction.
Abstract
Essential oils are widely used in the flavor, food, fragrance, and cosmetic industries in many applications. Contact allergy to them is well known and has been described for 80 essential oils. The relevance of positive patch test reactions often remains unknown. Knowledge of the chemical composition of essential oils among dermatologists is suspected to be limited, as such data are published in journals not read by the dermatological community. Therefore, the authors have fully reviewed and published the literature on contact allergy to and chemical composition of essential oils. Selected topics f...

Abstract P1-10-29: Randomized trial of aromatherapy vs. conventional care for breast cancer patients during perioperative periods
We examined Japanese breast cancer patients operated at Nahanishi Clinic , Okinawa, JAPAN.The patients were randomly assigned to a 2:1 ratio to aromatherapy or usual care following the informed consents were obtained. The aromatherapy group had aroma-oil (lavender, orange or ylang-ylang) placed at the bedside from 9 pm until 6 am. QOL of the patients was the primary endpoints and the changes of vital signs and the rate of hypnotic usage as secondary endpoints. QOL was assessed using the EORTC QLQ-C30,in which the Patients completed a baseline QOL assessment at the time of admission , of surgery day (AM7:00) and at the morn...

Adverse effects of aromatherapy: a systematic review of case reports and case series.
CONCLUSION: Aromatherapy has the potential to cause adverse effects some of which are serious. Their frequency remains unknown. Lack of sufficiently convincing evidence regarding the effectiveness of aromatherapy combined with its potential to cause adverse effects questions the usefulness of this modality in any condition.

Traditional Uses, Phytochemistry, and Bioactivities of Cananga odorata (Ylang-Ylang).
Authors: Tan LT, Lee LH, Yin WF, Chan CK, Abdul Kadir H, Chan KG, Goh BH
Abstract
Ylang-ylang (Cananga odorata Hook. F. & Thomson) is one of the plants that are exploited at a large scale for its essential oil which is an important raw material for the fragrance industry. The essential oils extracted via steam distillation from the plant have been used mainly in cosmetic industry but also in food industry. Traditionally, C. odorata is used to treat malaria, stomach ailments, asthma, gout, and rheumatism. The essential oils or ylang-ylang oil is used in aromatherapy and is believed to be effective in tr...

Efficacy of Thai herbal essential oils as green repellent against mosquito vectors.
Abstract
Repellency activity of Thai essential oils derived from ylang ylang (Cananga odorata (Lamk.) Hook.f. & Thomson: Annonaceae) and lemongrass (Cymbopogon citratus (DC.) Stapf: Poaceae) were tested against two mosquito vectors, Aedes aegypti (L.) and Culex quinquefasciatus (Say). There were compared with two chemical repellents (DEET 20% w/w; Sketolene Shield(®) and IR3535, ethyl butylacetylaminopropionate 12.5% w/w; Johnson's Baby Clear Lotion Anti-Mosquito(®)). Each herbal repellent was applied in three diluents; coconut oil, soybean oil and olive oil at 0.33μl/cm(2) on the forearm of volunte...

Molecules, Vol. 19, Pages 17943-17956: Efficiency of Vanilla, Patchouli and Ylang Ylang Essential Oils Stabilized by Iron Oxide@C14 Nanostructures against Bacterial Adherence and Biofilms Formed by Staphylococcus aureus and Klebsiella pneumoniae Clinical Strains
Biofilms formed by bacterial cells are associated with drastically enhanced resistance against most antimicrobial agents, contributing to the persistence and chronicization of the microbial infections and to therapy failure. The purpose of this study was to combine the unique properties of magnetic nanoparticles with the antimicrobial activity of three essential oils to obtain novel nanobiosystems that could be used as coatings for catheter pieces with an improved resistance to Staphylococcus aureus and Klebsiella pneumoniae clinical strains adherence and biofilm development. The essential oils of ylang ylang, patchouli an...

Structure of constituents isolated from the flower buds of Cananga odorata and their inhibitory effects on aldose reductase
Abstract
Three new terpenoid derivatives, canangaterpenes IV–VI, were isolated from the flower buds of Cananga odorata, cultivated in Thailand, together with eight known flavonoids. The chemical structures of the new compounds were elucidated on the basis of chemical and physicochemical evidence. The inhibitory effects of the isolated compounds on aldose reductase were also investigated. Several terpenoid derivatives and flavonoids were shown to inhibit aldose reductase.

Aroma helps to preserve information processing resources of the brain in healthy subjects but not in temporal lobe epilepsy
Conclusion: The current results show that exposure to the ylang–ylang aroma reduced information processing resources in healthy subjects but had limited effects in patients with TLE. We suggest that impaired higher-order olfactory processing in TLE patients may inhibit the effects of the ylang–ylang aroma on the P300. (Source: Seizure: European Journal of Epilepsy)
