Abstract A phytochemical study of the rhizome essential oils four different Hedychium species was performed by means GC and GC/MS analyses. H. ellipticum mainly contained 1,8‐cineole, sabinene, terpin‐4‐ol, while aurantiacum possessed para ‐cymene, bornyl acetate as major entities. Similarly, trans‐meta ‐mentha‐2,8‐diene linalool were noticed in coronarium. Three collections ( I – III ) spicatum showed amazing differences relative contents their oils, 1,8‐cineole 10‐epi‐ γ ‐eudesmol being...
Abstract This study includes a comparative investigation to analyze the phytochemical composition, nematicidal efficacy, in vitro AChE inhibitory activity, and molecular docking of Leucosceptrum canum . (LC) extracts. Various polarity solvent extracts including hexane (LCHE), dichloromethane (LCDE), methanol (LCME) were prepared from LC aerial parts using Soxhlet extraction. Phytochemical analysis was done GC‐MS technique identify quantify presence bioactive compounds revealing that LCHE is...
AbstractAbstractZanthoxylum armatum DC. is a medicinally important deciduous shrub belonging to the family Rutaceae, which widely distributed in Eastern and South Asia. The aim of present study was assess chemical composition essential oil bark Z. collected from three different altitudes Kumaun region, Uttarakhand, India, determine antioxidant, vitro anti-inflammatory antibacterial activity oils. plant material subjected hydro-distillation using Clevenger apparatus order obtained volatile...
The aim of present study was to evaluate chemical composition and different biological activities viz., pharmacological antioxidant essential oils. oils determined by gas chromatography/mass spectrometry while were evaluated standard protocols. Essential Hedychium spicatum Sm. from two ecological niches viz; Nainital (Site-I) Himachal Pradesh (Site-II) India revealed the qualitative quantitative chemo-diversity. Both dominated oxygenated terpenoids. Major marker compounds identified...
Abstract The essential oil obtained from rhizomes of Hedychium coronarium Koenig and spicatum Buch-Ham. growing wildly in Kumaun region central Himalaya were analysed by GC GC-MS. Forty six compounds representing 98.7 % H. identified. main components identified linalool (29.3 %), limonene (20.3 trans-meta-mentha,2,8diene (12.9 γ-terpinene (8.9 %) 10-epi-γ-eudismol (3.8 %).Thirty accounting 87.4 identified.The major constituents 1,8-cineole (17.6 α-eudesmol (17 (9.7%), δ-cadinene (7.5 cubenol...
The chemical composition of hydro-distilled essential oil from rhizomes Curcuma amada was analysed. Nineteen compounds representing 77.31% the total were identified by GC and GC-MS. Rhizomes extracted various solvents with different polarities using antioxidant assay systems. petroleum ether extract showed potent DPPH radical scavenging activities (IC50 = 18.98 ± 0.05) reducing power (A700 0.861 0.001). Ethyl acetate exhibited remarkable nitric oxide activity (IC 50 5.97 0.09) higher than...
The study was performed to check the chemical, antioxidant, antimicrobial and protein binding qualities of hydro-ethanolic extract Tinospora cordifolia (TC). In qualitative quantitative analysis extract, major compounds were tinocordioside, cordifolide A, palmatine, quercetin, β-sitosterol, heptacosanol, syringin. Hydro-ethanolic TC exhibited low antibacterial antifungal activities. Excellent antioxidant activities (60–80 %) noticed for various assays viz DPPH...
Present research reports chemical composition, antioxidant, anti-inflammatory insect anti-feedant, and sprout suppressant activity in essential oil from aerial parts of Cotinus coggygria Scop. (syn. Rhus cotinus) growing widely Uttarakhand, Himalaya. C. is commonly known as 'smoke tree' or bush' due to its flowers those give the smoke like appearance. It an ornamental plant with many medicinal usages. GC/MS analysis identified over 52 compounds, which contributed 96 % total oil. The...
Micromeria biflora Benth. (Lamiaceae) is an important medicinal herb used widely for treating the ailments like nose bleeds, toothaches, wounds, and sinusitis. The essential oil (EO) of collected from Bageshwar, Uttarakhand in India was examined by GC GC/MS, which contributed 97.1% total oil. EO found to be dominated E-caryophyllene (19.6%), geranial (16.2%), neral (11.5%) caryophyllene oxide (10.8%). studied antioxidant, antiamylase, nematicidal, antifeedant, insecticidal, antimicrobial...
The essential oils from fresh aerial parts of Mentha spicata L. collected ten different natural habitats Uttarakhand, India were analyzed by a combination GC, GC/MS and NMR spectroscopy. analysis revealed that monoterpenoids (46.1%-91.6%), mainly carvone (15.3%-68.5%), piperetenone oxide (24.0%-79.2%) alpha-humulene (0.1%-29.9%), the major constituents oils, but with significant qualitative quantitative differences among other constituents. Cluster oil composition was carried out in order to...
The volatile constituents of the rhizomes and aerial parts Globba sessiliflora Sims were analyzed by a combination gas chromatography (GC) chromatography–mass spectrometry (GC–MS). major identified in rhizome oil β-caryophyllene (20.1%), α-cadinol (14.7%), selin-11-en-4α-ol (12.0%), caryophyllene oxide (8.6%), γ-eudesmol (7.1%) myrcene (4.7%). from part contained (15.8%), (12.3%), (11.0%), β-longipinene (10.9), manool (8.1%), germacrene D (5.2%) β-eudesmol (4.1%) as constituents. Both oils...
