Effect of Soil Parameters on Rhizome Chemical Profiles of Different Accessions of Hedychium Spicatum Sw. Grown in Uttarakhand, India

ABSTRACTHedychium spicatum Sw. is utilized in treating several ailments due to its medicinally richrhizome. Present study aims to analyze the effect of soil parameters on H. spicatum rhizomeessential oils (HSREOs). Ten accessions of H. spicatum rhizomes were collected from variouslocations of Uttarakhand. HSREOs were extracted by hydro-distillation using a Clevenger-typeapparatus and characterized by GC and GC-MS. Results revealed identification of 89.74-94.96%of HSREOs, composed of oxygenated monoterpenes (32.4-80.46%) followed by oxygenatedsisquiterpene (2.08-38.59%), sisquiterpene hydrocarbon (0.26-19.84%) and monoterpene hydrocarbon (1.8-19.47%). Dominant oil chemicals were: 1,8-cineole, linalool, τ-cadinol, δ-cadinene, cubebol, γ-eudesmol, sabinene, germacra-4(15),5,10(14)-trien-1-α-ol, limonene and cis-γ-bisabolene. Pearson’s analysis of soil effect on HSREOs indicated positive correlation ofsoil EC, Mn and K with oils’ limonene; Mn and K with linalool and negative correlation of OCwith limonene; K with 1,8-cineole and Zn with eudesmol. Thus, a quantitative effect on oils’composition was observed due to soil variation.
