“…most of which have Mediterranean origin and among them, three have high commercial value. While the essential oil quality of the lavender species (British lavender) is high the lavandin species (hybrid lavender) have high essential oil yield [2,3]. It plays an important role in the pharmacology and perfumery industries since it contains essential and aromatic oils [4].…”

Abstract:The content of the extracts obtained from Lavandula angustifolia, which were grown in Burdur Örtülü locality, was determined via HPLC and GC-MS analysis and the anti-microbial effect of the essential oil L. angustifolia was also investigated. The dried flowers of L. angustifolia were extracted and the essential oil was distilled from the remaining part. Various phenolic compounds in the extract were quantitatively determined by HPLC. Quantitatively caffeic acid, rosmarinic acid, and 4-hydroxybenzoic acids were the most abundant phenolic acids in the content in decreasing order. 31 different compounds were determined by GC-MS analysis: Linalool and linalyl acetate have the highest concentration. Anti-microbial effects of the essential oil of L. angustifolia were determined against the most frequently encountered microorganisms in the cosmetics: Candida albicans, Staphylococcus aureus, Pseudomonas aeruginosa, and Aspergillus brasiliensis. It was observed that the essential oil L. angustifolia could completely remove the contamination caused by the microorganisms as of the 14 th day. According to the results it is concluded that the essential oil of L. angustifolia, can be used either directly or incorporated into the cosmetics without the necessity for any other extra preservative against the above mentioned microrganisms.

“…42,43 Fresh herb oil is primarily composed of aliphatic aldehydes (primarily C10-C16 aldehydes), which have a fetid scent, 44 while the oil extracted from coriander fruit is primarily composed of linalool and a few other oxygenated monoterpenes and monoterpene hydrocarbons. 45 Additionally, coriander contains a significant number of essential oils (EO), which are crucial for brain and development activities, as well as lipids like petroselinic acid. Linalool, linoleic, and linolenic acids make up most of the coriander essential oil.…”

Traditional medicine has received more attention in recent years. Numerous plants have been employed in medicine to treat neurological disorders like AD and other memory-related problems. Traditional uses for dietary, spice, and food additive medicinal purposes included the use of, Nigella sativa, Crocus sativus, Ferula assafoetida, Coriandrum sativum, Zataria multiflora, Thymus vulgaris Cats Claw, and Carotenoids, monoterpenes, and polyphenol chemicals, which are the main ingredients in these plants, improved neurological processes. These healing plants improved antioxidant production, reduced oxidative stress, and prevented the neurological system's acetylcholinesterase enzyme from working. Reduced production of proinflammatory cytokines such IL-6, TNF-an ,IL-1b, NF-Kβ, Bax Protein, Bcl-2,Caspase-3 and total nitrite is another way that plants are neuroprotective. As a result, the effects of the aforementioned medications and their active ingredients improved neurodegenerative diseases, indicating their therapeutic promise in diseases like AD and depression that are linked to neuro-inflammation and neurotransmitter deficit.

“…This amount was designed to represent a grossly exaggerated quantity as compared to that occurring naturally in plants, so as to force a sizeable quantity to be passed over into the sodium picrate solution. Cymbopogon citratum was also examined as a natural, rich source of low molecular weight carbonyl derivatives such as isovaleraldehyde, citronellal, n-decylaldehyde, citral, aand b-farnesal, methyl heptenone, and a,b-isopseudoionone (Guenther, 1950), compounds sufficiently volatile to cause possible interference. The results shown in Table 3 expose the capability of some of the most volatile among these compounds to disrupt the qualitative analysis.…”

A procedure for the quantitative determination of hydrogen cyanide (HCN) released by plants has been developed based on the UV-vis spectrum of the sodium picrate-cyanide complex. Fresh plant tissue mixed with toluene was placed in a gas flow system designed to carry the evolved HCN through 2,4dinitrophenylhydrazine solution in acidic water:ethanol to trap interfering volatile carbonyl derivatives, and then into an alkaline solution of sodium picrate. After 18 h of gas flow at a rate of 6 mL/min, the absorbance of the solution was measured at 500 nm and the concentration of HCN was determined by calibration in the range 10 À3 -10 À5 M. The molar absorptivity coefficient (1.385 L/cm M) yielded a detection limit of 2.6 Â 10 À6 mol/L and a 92.6 AE 2.6% recovery yield of HCN. The method was applied to determine the cyanide release capacity of Passiflora capsularis (up to 3.34 mg of HCN/g fresh plant tissue), and of croziers of Pteridium aquilinum var arachnoideum (10.4-61.3 mg of prunasin/g fresh plant tissue), and its rate of HCN production (K = 2.20 AE 0.01 Â 10 À4 / s ). Cymbopogon citratum, known to release large quantities of volatile, potentially interfering, monoterpene ketones and aldehydes, gave a negative reaction. Copyright
