Objective: To study optimum inclusion process condition for volatile oil with beta-cyclodextrin (beta-CD).
Methods: The optimum preparation condition were investigated by orthogonal design. The influence of utilization beta-CD and oil, inclusion temperature and time were studied to determin the utilization ratio of volatile oil and oil-bearing rate.
Results: The optimum preparation conditions were established as: volatile oil: beta-CD was 1:10, the inclusion temperature was 60 degrees C and inclusion time was 3h.
Conclusion: The method is convenient and can he used for mass production.

Background: Amorpha fruticosa was used for treating burn, ambustion, carbuncle, and eczema in the traditional Chinese medicine. Although more and more attention has been paid to its biological activity recently, the antitumor activities of the essential oils (EOs) extracted from its leaves (AFLEO) and flowers (AFFEO), and their molecular mechanisms have never been reported up to now. The objective of present study was to examine the chemical compositions of AFLEO and AFFEO, then investigate the effects and pharmacological mechanism of EOs against hepatocellular carcinoma (HCC).

Various practical strategies have been employed to mitigate the detrimental effects of water deficit stress on plants such as application of nano-stimulants. Nanosilicon plays a crucial role in alleviating the deleterious impacts of both abiotic and biotic stresses in plants by modulating various phyto-morphological and physiological processes. This study aimed to examine the combined effects of drought stress and nanosilicon application on the morphological traits and essential oil content and compositions of hemp (Cannabis sativa L.

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).

The goal of the present work is to quantify the performance of ozonation as a method for the in situ remediation of soils polluted at varying degree with different types of hydrocarbons, and assess its applicability, in terms of remediation efficiency, cost factors, and environmental impacts. Ozonation tests are conducted on dry soil beds, for three specific cases: sandy soil contaminated with low, moderate and high concentration of a non-aqueous phase liquid (NAPL) consisting of equal concentrations of n-decane, n-dodecane, and n-hexadecane; sandy soil polluted with diesel fuel; oil-drilling cuttings (ODC). The transient changes of the concentration of the total organic carbon (TOC), total petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAHs), and soluble chemical oxygen demand (SCOD) in soil and carbon dioxide (CO), carbon monoxide (CO), volatile organic compounds (VOCs), and ozone (O) in exhaust gases are recorded.

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.
