Mentha suaveolens, Lavandula stoechas, and Ammi visnaga are widely used in Moroccan folk medicine against several pathological disorders, including diabetes and infectious diseases. This work was designed to determine the chemical profile of M. suaveolens (MSEO), L. stoechas (LSEO), and A. visnaga (AVEO) essential oils and assess their antimicrobial, antioxidant, and antidiabetic effects. The volatile components of LSEO, AVEO, and MSEO were analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). The in vitro antidiabetic activity was assessed using α-amylase and α-glucosidase enzymes, while DPPH, FRAP, and β-carotene/linoleic acid methods were used to determine the antioxidant capacity. The antimicrobial activities were investigated using disc diffusion and broth-microdilution assays. GC-MS investigation revealed that the main components were fenchone (29.77 %) and camphor (24.9 %) for LSEO, and linalool (38.29 %) for AVEO, while MSEO was mainly represented by piperitenone oxide (74.55 %). The results of the antimicrobial evaluation showed that all examined essential oils (EOs) had noticeable antimicrobial activity against both bacteria and yeast, especially Micrococcus luteus and Bacillus subtilis. The MIC, MBC, and MFC values were ranged from 0.015 % to 0.5 %. The MBC/MIC and MFC/MIC ratios were less than or equal to 4.0 % (v/v), indicating their noticeable bactericidal and candidacidal efficacy. Moreover, the three EOs showed significant inhibitory effects on α-amylase and α-glucosidase (p < 0.05). It also exerted remarkable activity on FRAP, β-carotene, and DPPH radicals. These findings demonstrated that the tested plants have promising biological activities, validating their ethnomedicinal value and providing potential applications as natural drugs.

Lately, the entire society's focus has turned towards consuming more natural food products and the production of chemicals obtained utilising green technologies. The use of chemicals as food additives is a concern for consumers. For this reason, the search for natural and more sustainable additives is a key step to control food risks while meeting consumers' requirements.

The present study is centred on the analysis of the chemical compositions of essential oils (EOs) and volatile fractions extracted from the aerial parts of L. (APDSL) utilising traditional hydrodistillation (HD), solid phase microextraction (SPME), and a novel method known as innovative cigarette ignition (Incigig), all in combination with GC/MS. The results of this investigation reveal notable differences in both the types and relative percentages of the primary constituents; however, all identified profiles exhibit a significant presence of non-terpene hydrocarbons.

Exhaled breath offers an interesting matrix of low invasive sampling of potentially relevant information about the organism's metabolism in the form of volatile organic compounds (VOC). The VOC can be exhaled by the ructus (Islam et al., 2023) or passed the blood-lung barrier for expiration through the lungs.

Santalum album is an economically important plant in the craft, spices and medicine industries. The main chemical constituents found in sandalwood essential oils are sesquiterpenes. 3-Hydroxy-3-methylglutaryl monoacyl-coenzyme A reductase (HMGR) is one of the rate-limiting enzymes required for the synthesis of sandal sesquiterpenes, but there are no studies on the HMGR gene in S.
