Cupressus torulosa is an evergreen tree with a wide distribution in north-western Himalayan region of India. Its needles have long been used traditional medicine for anti-inflammatory, antimicrobial, and wound-healing properties. This study aimed to scientifically validate the claim treat inflammation by evaluating chemical composition, antioxidant potential, anti-inflammatory activity essential oil extracted from (CTEO) using hydro-distillation. Qualitative quantitative composition CTEO was...

The essential oils derived from various coniferous species, including Cupressus torulosa, have been historically valued for their aromatic properties. In the present study, oil C. torulosa needles (CTEO) was analyzed using Gas Chromatography (GC), Chromatography-Mass Spectrometry (GC-MS), and Chromatography-Olfactometry (GC-O) with Aroma Extract Dilution Analysis (AEDA). A total of 36 compounds were identified, δ-3-carene (0.1824 ± 0.0084 mg/g), sabinene (0.1125 0.036 terpinen-4-ol (0.0891...

This research investigates the chemical composition of flower essential oil Robinia pseudoacacia (FEORP) by GC-MS analysis and reports its antimicrobial efficacy against selected foodborne pathogens. The FEORP confirmed presence 27 compounds which represented 94.46 % total oil. Further, (1000 μg/disc) exhibited significant effects some pathogens such as Staphylococcus aureus KCTC 1621, Bacillus subtilis 3569, Listeria monocytogenes Escherichia coli O157:H7 Salmonella enterica ATCC 4731 with...

AbstractCupressus torulosa, a large aromatic evergreen conifer tree widely distributed in the northwestern Himalayan region of India, holds various traditional uses its aerial parts. The objective this study was to compare essential oil content and chemical composition C. torulosa needles obtained using two distinct distillation methods: hydro-distillation (HD) steam-water (SWD). Gas Chromatography with Flame Ionization Detector (GC-FID) Chromatography-Mass Spectrometry (GC-MS) techniques...

Prinsepia utilis Royle, native to the Himalayas, is esteemed in Chinese and Indian folk medicine for its diverse medicinal benefits, targeting arthritis, pain relief, bone disorders, joint discomfort. This study examined 25% aqueous methanol extract of P. leaves using UPLC-Q-TOF-MS/MS, identifying 78 metabolites, 76 which were reported first time utilis. These included 64 phenolics represented by 56 flavonoids, 5 phenolic acids, 3 glycosides, 4 terpenoids, 2 lignan 8 other compounds,...

ABSTRACT This study aimed to assess the geographical variation in content and chemical composition of Cupressus torulosa needles essential oil across different locations Himalayan region India. The methodology involved collection from 14 distinct locations, followed by hydro‐distillation using a Clevenger‐type apparatus. Qualitative analysis was conducted gas chromatography–mass spectrometry (GC–MS), while chromatography with flame ionisation detector (GC‐FID) employed for quantitative...

An effort was made to investigate the chemical composition of hydrodistillated Ligustrum obtusifolium flower essential oil (LOFEO). Further, LOFEO tested against various foodborne pathogens confirm its antimicrobial effects. The GC-MS analysis confirmed presence 35 constituents in LOFEO, composing 84.91% oil. As expected, exhibited considerable inhibitory effects (zone inhibition: 12.6±0.1–18.2±1.0 mm) Bacillus subtilis KCTC 3569, Staphylococcus aureus 1621, Listeria monocytogenes Salmonella...
