Chemical composition and bioactivities of the volatile oil of the seeds of Eryngium bungei Boiss.
The volatile oil of the seeds of Eryngium bungei Boiss. (family Apiaceae), was obtained by hydrodistillation and analyzed by the GC-MS and the GC-FID. The analyses revealed at least 69 compounds representing 94 % of the total oil. The results showed that the oil was dominated by chrysanthenyl acetate (20.0 %), spathulenol (17.2 %), endo-isofenchol (10.8 %) and α-pinene (5.1 %). The free-radical-scavenging activity of the oil was evaluated by DPPH assay and RC50 value was calculated as 7.5 µg/mL. The antifungal and phytotoxic activities of the oil were tested against Sclerotinia sclerotiorum, and some common weeds. The MIC value for anti sclerotinia activity of the seed oil was evaluated as 12.5 µg/mL. The IC50 values were determined as 1.32-2.1 µg/mL for inhibitory effects of the oil on seed germination of different weeds. This is the first report on chemical composition and bioactivities of the volatile oils of the seeds of Eryngium bungei.
