“…LEO is considered GRAS and contains as main components: linalyl acetate (22-50%) and linalool (11-53%) (Kivrak, 2018). LEO is recognised for several therapeutic effects, such as: sedative, relaxant, antioxidant, anti-depressive, anti-inflammatory, anticonvulsive, antiviral and antibacterial as well as for gastrointestinal, nervous and rheumatic disorders (Jalali-Heravi, Moazeni-Pourasil, & Sereshti, 2015). However, the stability of LEO is limited to factors such as air, light, moisture and temperature under natural ambient temperature conditions.…”

Black rice and lavender are promising sources of bioactives, in terms of anthocyanins and essential oils. Their bioaccessibility were improved by microencapsulation, followed by mixing in order to benefit both from colour and flavour, along with radical scavenging and biological properties. The mixed powder showed a satisfactory anthocyanins of 2.55 mg g −1 DW, leading to a radical scavenging activity of 65.14 mmol g −1 DW. The powder displayed an inhibitory effect against α-glucosidase (~49%) and α-amylase (39%), respectively, with a controlled release in intestinal environment. To further examine the functional properties, the powder was added to a food model system. During storage, a release in anthocyanins and flavonoids were found, leading to an increase in radical scavenging activity. The sensorial analysis showed that supplemented biscuits were appreciated for colour and lavender aroma. The obtained results were promising in tailoring the health benefits of secondary metabolites, underutilised in human's nutrition due to their low stability and bioavailability.

In this study, the chemical composition and antimicrobial activity of the essential oil (EO) from aerial parts of Rhetinolepis lonadioides collected from southwestern Algeria were assessed. The EO was obtained by hydrodistillation and analyzed by GC/MS. In total, thirty-two compounds were identified representing 80.00% of the total of the EO, withβ-Pinene (41.85%) being the major monoterpenes. Phenanthroquinone (10.39%) and Ethanone, 1-[1,1'-biphenyl]-4-yl- (2.66%) were the main oxygenated monoterpenes, and the diterpene hydrocarbons were mainly represented by m-Camphorene (5.43%). Six EO samples of R. lionadioides collected in location exhibited similar chemical composition evidencing a chemical homogeneity. The agar disc diffusion method showed that R. lonadioides EO was effective against Bacillus cereus, Pseudomonas aeruginosa, and Staphylococcus aureus with diameters of inhibition ranging from 17±2.65 to 12.33±1.13 mm, and the minimum inhibitory concentration (MIC) values were between 4 and 10 µL /mL. The lowest MIC values (4.0 µL/mL) were measured for Bacillus cereus.

“…For this purpose, curve resolution techniques result in chromatographic and spectral profiles of pure components. Examples of such techniques are heuristic evolving latent projections, orthogonal projection resolution, evolving factor analysis, window factor analysis, sub-window factor analysis, simple interactive self-modeling mixture analysis, evolving window orthogonal projections, alternating regression, iterative target transformation factor analysis and multivariate curve resolution-alternating least squares [15,17,18,34,35].…”
