Abstract
This study was carried out to find the allelopathic effect of volatile materials released fromEupatorium rugosum. The GC method was employed for analysis of volatile materials from E. rugosum and 49 chemical substances were identified such as β-caryophyllene, α-terpinenol, chamazulene, bornyl acetate, α-pinene, etc. including unidentified thre chemicals. Germination test in Phaseolus radiatus was done to find the inhibition effect of volatile materials using some chemicals which were proved to be important component or much amounts ones in E. rugosum. It was strongly inhibited by linalool and terpinen-4-ol. Seedling elongation and radicle growth of that were proportionally inhibited by the concentration of the essential oil, especially α-pinene and bornyl acetate. Biomass of receptor plant was slightly decreased more than 58 μl of the extract in case of α-pinene, while it was decreased more than 19 μnon-significant. From the above results, it was found that volatile materials from E. rugosum showed a allelopathic effect and also α-pinene, bornyl acetate, linalool and terpinen-4-ol used in bioassay were some of major allelochemicals in germination inhibition and especially linalool and terpinen-4-ol are prominent effect on growth inhibition of other plant.
