ABSTRACTThe essential oils extracted from the leaves, inflorescence, whole aerial-parts and root of patchouli [Pogostemon cablin (Blanco) Benth.] were analyzed and compared using GC-FID and GC-MS. Altogether thirty-four constituents, representing 86.9–97.7% of the total oil compositions, were identified. Major constituents of the oils of aerial-parts (leaves, inflorescence and whole aerial-parts) were patchouli alcohol (42.2–57.7%), α-bulnesene (9.0–15.2%), α-guaiene (6.4–17.9%), seychellene (3....

An investigation was carried out to assess the genetic variability, genetic divergence and association of pheno-morphic and agronomic traits along with major chemical constituents of essential oil in 41 accessions of spearmint (Mentha spicata L.). Highly significant differences were noted for all 10 economic traits indicating the existence of considerable genetic variability among 41 accessions. High heritability (h2) and high genetic advance was noted for herb yield (120.64 %). On the basis of ...

The essential oil compositions of leaves and inflorescences of Elsholtzia densa Benth. from western Himalaya were studied and compared using gas chromatography-flame ionization detector and gas chromatography-mass spectrometry. Altogether, forty constituents comprising 83.3–83.7% of essential oil composition were identified. The leaf essential oil of E. densa was characterized by citral (52.2%), geranyl acetate (3.3%) and geraniol (3.1%), whereas the inflorescence essential oil of E. densa was f...

ABSTRACTThe influences of cropping seasons, crop maturity stages and wilting period on essential oil composition of Ocimum africanum Lour. var. CIM-Jyoti, grown at foothills agroclimatic conditions of northern India, were studied and compared using gas chromatography–flame ionization detector and gas chromatography–mass spectrometry. Altogether, 28 constituents, forming 91.8–99.1% of the total oil composition, were identified by comparing their retention indices and mass spectral data. The essen...

Abstract This study investigates the variations in the chemical, genetic, and biological activity (antibacterial, antifungal, and antioxidant) profiles of thirteen populations of Ocimum kilimandscharicum Guerke (OK1-OK13) from India. Correlations between chemical composition and the biological activities of O. kilimandscharicum were assessed. The essential oils (EOs) of different populations, extracted by hydrodistillation process were characterised by gas chromatography-flame ionization detecto...

In this study, the essential oil composition and antibacterial activity of an underexplored population of Cymbopogon martinii (Roxb.) W. Watson was investigated using GC–FID, GC–MS, disc diffusion and micro dilution broth assay. To substantiate the stability of the essential oil profile, the population was grown in the experimental field and its oil was analysed at different growth stages. Altogether, forty-eight constituents, comprising 91.5–96.8% of the total oil composition were identified. M...
