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.
Materials And Methods: Three samples of essential oils were prepared by steam distillation. Their composition was established with GC/MS. The effects of the oils were examined in PANC-1 human pancreas cancer cells and Crl mouse breast cancer cells in concentrations ranging from 10-400 microg/ml, measuring the reduction of the tetrazolium salt 3-(4,5-dimethylthiazol-2-yl) -5- (3-carboxymethoxyphenyl)-2- (4-sulphophenyl) -2H-tetrazolium (MTS) by mitochondrial enzymes.
Results: Two types of essential oils were found, differing mainly in the absence or presence of beta-phellandrene. The ED50 of the oils ranged from 48.6 microg/ml to 108.3 microg/ml for PANC-1 and 48.0 microg/ml to 91.8 microg/ml for Crl cells.
Conclusion: The cytotoxic activity of the essential oils was independent of the quantity of their main components.

A nanoemulsion was fabricated from Cananga odorata essential oil (EO) and stabilized by incorporation of Tween 80 using ultrasonication. The major constituents of the EO were benzyl benzoate, linalool, and phenylmethyl ester. Differing sonication amplitude (20-60%) and time (2-10 min) were assessed for effects on nanoemulsion droplet size and polydispersity index (PI).

α-Terpineol and 1,8-cineole are two important compounds in essential oils. This study developed an efficient method to recover α-terpineol from model oil (MO) based on association extraction by in situ formations of deep eutectic solvent (DES) between α-terpineol and some quaternary ammonium salts (QASs) by hydrogen-bond (HB) interaction. Such interaction could be broken almost completely by the introduction of water, due to the stronger HB interaction between water and QASs, which could release α-terpineol by liquid-liquid separation and save the organic solvents consumption.

Resins are complex mixtures of natural constituents containing non-volatile and volatile terpenes, in combination with gums and polyphenols, used since ancient times for their medicinal properties. Current research has evidenced their therapeutic value with a plethora of activities. The main limits of resins and their constituents for their clinical use are low water solubility, poor stability and bioavailability.
