“…Other main components of this essential oil were found to be β-terpinyl acetate (13.7 ± 1.9%), eugenol methyl ether (11.7 ± 1.8%), linalyl acetate (5.8 ± 0.6%), sabinene (4.1 ± 0.9%), α-pinene (4.1 ± 0.3%), as well as terpinen-4-ol (3.6 ± 0.3%) and β-pinene (3.2 ± 0.9%). Taban et al [46] mentioned the presence of α-pinene (2.94-4.11%), β-pinene (2.51-3.22%), cis-sabinene hydrate (0.49-1.03%), eugenol (0.55-1.03%), methyleugenol (2.34-3.99%) and trans-caryophyllene (0-1.33%) in the chemical composition of the L. nobilis essential oil. Constituent analysis indicated the presence of volatile compounds such as isoeugenol (53.50%), myrcene (16.60%), and chavicol (10.20%) in the chemical composition of the L. nobilis essential oil [47].…”

Bay Leaf (Laurus Nobilis L.) Incense Improved Scopolamine-Induced Amnesic Rats by Restoring Cholinergic Dysfunction and Brain Antioxidant Status

Bay leaf (Laurus nobilis L.) has been shown to possesses various biological activities such as wound healing activity, antioxidant activity, antibacterial activity, antiviral activity, immunostimulant activity, anticholinergic activity, antifungal activity, insect repellant activity, anticonvulsant activity, antimutagenic activity, and analgesic and anti-inflammatory activity. The present study aimed to investigate whether the bay leaf incense (BL) elicits the memory formation via the action on the cholinergic system using a scopolamine (Sco)-induced rat model. Rats were exposed to BL over 5 min in a smoking chamber apparatus once daily for 22 days, whereas memory impairment was induced by Sco (0.7 mg/kg), a muscarinic receptor antagonist, delivered 30 min before each behavioral test. The phytochemical composition of BL was achieved by gas chromatograph–mass spectrometry (GCMS). Behavioral effects in rats were assessed by Y-maze, radial arm maze (RAM), and novel object recognition (NOR) paradigms. Additionally, the acetylcholinesterase (AChE) activity and the oxidative stress markers in the rat hippocampus were also evaluated. Exposure to BL significantly ameliorated Sco-induced cognitive impairment and oxidative stress in the rat hippocampus. The obtained results suggested that BL-induced ameliorative cognitive effects are mediated by enhancement of the cholinergic system and antioxidant activities.

“…The dried leaves of Laurus nobilis are used as a spice or flavoring agent in the culinary and food industries [ 13 ]. The essential oil (EO) prepared from the leaves has been reported to have antibacterial, antioxidant and anti-inflammatory activities [ 14 , 15 ]. Further leaves of Laurus nobilis have been also used to treat rheumatism, neuralgia, and scabies [ 16 , 17 ].…”

Diabetes mellitus (DM) has been treated with herbs for centuries and many herbs reported to exert antidiabetic activity. Laurus nobilis is an aromatic herb belonging to the Lauraceae family, commonly known as bay. This study aimed to investigate the activity of Laurus nobilis leave extracts on histopathological and biochemical changes in β-cells of streptozotocin (STZ)-induced diabetic rats. Thirty healthy adult male albino rats were included in the study and divided equally into 5 groups for 4 weeks as follow; control group (C), diabetic group (D), diabetic Laurus nobilis extract group (DLN), Laurus nobilis extract group (LN) and diabetic acarbose (DA) group. Histopathologically, D group rats exhibited various degenerative and necrotic changes in their liver, pancreas and kidney, whereas the DLN rats had nearly normal histology. Insulin immunostaining in the pancreatic beta cells was decreased in the D group compared to the C group, whereas the DLN group was similar to the C group. The glucose concentration decreased significantly in both diabetic rats treated with L. nobilis and acarbose ( p < 0.05). Additionally, the levels of aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT) and alanine aminotransferase (ALT) enzyme were significantly decreased in both diabetic rats treated with L. nobilis and acarbose, compared to the D group ( p ˃ 0.05). Outcomes of this study said that leave extracts of L. nobilis has valuable effect on blood glucose level and ameliorative effect on regeneration of pancreatic islets, it also restored the altered liver enzymes, urea, creatine kinase, total protein levels, calcium and ferritin to near normal.

“…It is a challenging area of research because the chemical profile of these products can be characteristic of specific plant genotype but also vary due to several biotic and abiotic factors (e.g., the stage of plant development, the part of the plant) as well as post-harvest treatments and extraction means [5]. Regarding L. nobilis EO, the effect of plant organ [6,7], gender [8], phenological stage [9], post-harvest handling [10] and EO production methods [11,12] have been examined to a certain extent.…”

Diagnostic Potential of FT-IR Fingerprinting in Botanical Origin Evaluation of Laurus nobilis L. Essential Oil is Supported by GC-FID-MS Data

et al. 2020

The last years, non-targeted fingerprinting by Fourier-transform infrared (FT-IR) spectroscopy has gained popularity as an alternative to classical gas chromatography (GC)-based methods because it may allow fast, green, non-destructive and cost-effective assessment of quality of essential oils (EOs) from single plant species. As the relevant studies for Laurus nobilis L. (bay laurel) EO are limited, the present one aimed at exploring the diagnostic potential of FT-IR fingerprinting for the identification of its botanical integrity. A reference spectroscopic dataset of 97 bay laurel EOs containing meaningful information about the intra-species variation was developed via principal component analysis (PCA). This dataset was used to train a one-class model via soft independent modelling class analogy (SIMCA). The model was challenged against commercial bay laurel and non-bay laurel EOs of non-traceable production history. Overall, the diagnostic importance of spectral bands at 3060, 1380–1360, 1150 and 1138 cm−1 was assessed using GC-FID-MS data. The findings support the introduction of FT-IR as a green analytical technique in the quality control of these often mislabeled and/or adulterated precious products. Continuous evaluation of the model performance against newly acquired authentic EOs from all producing regions is needed to ensure validity over time.
