“…Figure 4b shows the biplot designed to graphically demonstrate how the active components in volatile oils fluctuate over time depending on the time of collection. Evaluation of the stability of harvest dates is possible using the average coordinate axis resulting from characteristics and harvest dates (Akçura, 2023). In terms of volatile oil content and active components, the months of August, September, and July, which were closest to the mean axis in the positive direction, outperformed the other months.…”

This research was carried out to examine the monthly changes in both the volatile oil content and volatile components of cherry laurel leaves by taking samples every month for 12 months in Turkey. Harvest periods significantly affected volatile oil content (P < 0.01). Depending on harvest periods, volatile oil ratios ranged from 0.19 to 0.35%. The months of August, July, and September yielded the highest volatile oil ratios. Benzaldehyde, phenol, benzoic acid, benzeneacetonitrile, pentadecanone, 1,54-dibromotetrapentacontane and, tetrapentacontane were determined as components in the volatile oil. The ratio of benzaldehyde, the main active ingredient, varied between 83.89 and 94.41%, depending on the harvest time. The cherry laurel leaf should be harvested in July, August, and September for high essential oil ratios and in May, June, and July for high benzaldehyde ratios. Due to the high concentration of benzaldehyde in its volatile oil, cherry laurel evergreen leaf can be considered a valuable source of raw materials for the fragrance and pharmaceutical sectors.

Electrospinning method used in nanofiber production is an economical method applied with high voltage electricity.Essential oils obtained from natural sources have antioxidant, antimicrobial and antifungal properties and are preferred in the production of nanomaterials by electro-spinning method. In this study, tangerine peel (citrus unshiu) essential oil (TPEO) was obtained by hydro-distillation method. The major one of the 10 components of the extract detected by Gas Chromatography Mass Spectrometry (GS-MS) was D-Limonene (%77.45). The composite nanofiber was prepared with 25% TPEO and polylactic acid (PLA). Nanofibers were characterized by Scanning Electron Microscopy (SEM) and Thermogravimetric Analysis (TGA). According to the SEM results, it is seen that the essential oil is composited with prominent spheroidal structures in PLA nanofiber structure, and nanofiber diameter obtained is approximately 76.8 nm. Its decomposition temperature is about 320°C. Nanofibers obtained from tangerine peels and their antibacterial properties, can be recommended use for food preservation and medicine fields.
