| Popis: | The variations in essential oil yield and composition of Cymbopogon flexuosus var. GRL-1 were compared with respect to four different harvesting regimes in monsoon-influenced humid subtropical climate of north India. The essential oil yield was found to vary from 0.65 to 0.75% during different harvesting mode. GC and GC–MS analysis revealed 28 constituents comprising 93.0–99.7% of total compositions. Geraniol (58.9–75.5%) and geranyl acetate (9.5–26.6%) were identified as the major constituents. Other constituents detected with significant content were 1,8-cineole (0.3–4.8%), (E)-β-ocimene (≤ 0.03–2.3%), linalool (1.2–1.9%), and citronellal (0.2–1.6%). Significant variations were noticed in the herb and oil yield, and contents of geraniol and geranyl acetate due to different harvesting regimes. The results obtained could be of economic importance for obtaining higher yield of geraniol-rich essential oil from C. flexuosus var. GRL-1 for varied industrial applications. |
