Abstract
Inula koelzii of Astereaceae, an endemic plant growing at Ladakh and Kashmir regions, has been observed a potential allelopathic plant species. Further observing its allelopathic role, four subfractions (hexane, chloroform, butanol and water) were extracted from 80% MeOH of the aerial plant material. While using EDX technique for inorganic profile of each subfraction, it revealed 18 different elements i.e., C, O, Cl, K, Ca, Cr, Mn, Fe, Zn, Ag, Cd, Co, Ni, Cu, Al, Si, S and P. However, C, O, K, Fe, Zn and Co was present in highest percentages in each subfraction. Overall, chloroform (CHCl3) revealed a composition of 13 different elements and the most abundant were Cl, K, Ca, Zn, Co, Ni, Cu and Al. To know the allelopathic effect of each subfraction, dish pack method was used for bioassay with a concentration gradient of 10, 30
