“…Table 7 suggested that oil yield was positively correlated with the location temperature (r 2 = 0.697; p < 0.05) and negatively correlated with the altitude (r 2 = − 0.891; p < 0.01). This may be due to the excessive low temperature at higher altitudes that causes cold stress to the plant and result in the loss of plant yield and quality of oil, while in a previous study on Foeniculum vulgare from Himalayan region showed that the oil yield was the highest in the collections from higher altitudes (Pithoragarh and Didihat) [30]. In the present investigation, EO of thyme grown at different altitudes showed great variation in the percentage of major compounds such as thymol, α-terpineol, p-cymene, camphor and γ-terpinene.…”

Thymus serpyllum L., a well-known aromatic plant of the Himalayan region is often used in pharmaceutical, cosmetic, flavoring and fragrance industries because of its phenolic and non-phenolic constituents. The amount of these compounds varies with the origin, the climatic conditions and the developmental stage of harvesting time of the plant. Under different environmental conditions, plant specimen of the same species respond differently through production and accumulation of the primary and secondary metabolites. In the present work, T. serpyllum L. was collected from its natural habitat and grown at different agro-climatic zones, i.e., Auli (higher Himalayas; 2744 m asl), Pithoragarh (lower Himalayas; 1524 m asl) and Haldwani (foothill areas; 412 m asl). The essential oil from fresh aerial parts of cultivated plants at full blooming stage was obtained using Clevenger apparatus and analyzed by GC-FID and GC-MS. The amount of thymol was also quantified by HPTLC. The data were statistically analyzed using MS Excel and SPSS 16.0. The percentage yield of the essential oils varied from 0.20 to 0.84%. Thymol was the major compound found in all the three cultivations, being the highest for Haldwani (84.63%) followed by Auli (50.80%) and Pithoragarh (41.15%) cultivations. Camphor was the second major compound, only identified in Pithoragarh (36.34%) region. Alpha-thujene, p-cymene, alpha-terpineol, (E)-caryophyllene, beta-bisabolene, alpha-pinene and carvacrol were also identified in significant amounts. HPTLC quantification suggested the similar pattern of thymol percentage as obtained from GC-FID. The study revealed that there was a significant difference in the terpenoid constituents of the plant grown at different agro-climatic zones. Thymus serpyllum grown at lower altitude area (warm climatic zone) can be a potential source of thymol along with high essential oil yield.

“…Thus, FEO, which was cultivated from five different agro-environmental conditions in India, represented that the concentrations of limonene in FEO cultivated from Moradabad (latitude: 28 • 3 N; longitude: 78 • 77 E), Tanakpur (latitude: 29 • 07 N; longitude: 80 • 10 E), and Haldwani (latitude: 29 • 13 N; longitude: 79 • 31 E) detected more than 30% of FEO; however, the concentrations of limonene in FEO cultivated from Pithoragarh (latitude: 30 • 08 N; longitude: 80 • 36 E) and Didihat (latitude: 29 • 80 N; longitude: 80 • 24 E) detected less than 10% of FEO. Additionally, the concentrations of trans-anethole in FEO cultivated from Moradabad and Haldwani detected less than 30% of FEO, while concentrations of trans-anethole in FEO cultivated from Tanakpur, Pithoragarh, and Didihat detected more than 40% of FEO [12]. Furthermore, volatile profiles of fennel in Spain have been identified where the concentrations of volatile compounds were varied according to the agor-environmental conditions [13].…”

In this study, odor components were analyzed using gas chromatography/mass spectrometry (GC/MS) and solid-phase microextraction (SPME), and odor-active compounds (OACs) were identified using GC-olfactometry (GC-O). Among the volatile compounds identified through GC-O, p-anisaldehyde, limonene, estragole, anethole, and trans-anethole elicit the fennel odor. In particular, trans-anethole showed the highest odor intensity and content. Changes in body weight during the experimental period showed decreasing values of fennel essential oil (FEO)-inhaled groups, with both body fat and visceral fat showing decreased levels. An improvement in the body’s lipid metabolism was observed, as indicated by the increased levels of cholesterol and triglycerides and decreased levels of insulin in the FEO-inhaled groups compared to group H. Furthermore, the reduction in systolic blood pressure and pulse through the inhalation of FEO was confirmed. Our results indicated that FEO inhalation affected certain lipid metabolisms and cardiovascular health, which are obesity-related dysfunction indicators. Accordingly, this study can provide basic research data for further research as to protective applications of FEO, as well as their volatile profiles.

“…verificou-se a presença dos sesquiterpenos α-santalal e α-cadineno em grande altitude, e ausência deles no óleo da planta cultivada em baixa altitude. Alguns monoterpenos oxigenados como verbenol, pinocarvona, p-mentha-1,5-dien-8-ol, myrtenal, transmyrtenol, trans-carveol e trans-3-caren-2-ol foram detectados apenas em baixas altitudes (PUNETHA et al, 2019).…”
