Chemical Composition, Some Allelopathic Aspects, Free-Radical-Scavenging Property and Antifungal Activity of the Volatile Oil of the Flowering Tops of Leucanthemum vulgare Lam.

Hydrodistillation of the ground flowering tops of Leucanthemum vulgare (Asteraceae), collected from Heyran (Ardabil Province, Iran), afforded a greenish yellow oil (yield 0.15%, v/w), which was analyzed by the GC-MS and the GC-FID. The volatile oil comprised 47 compounds representing 90.3% of the oil. Caryophyllene oxide (21.2%), aromadendrene oxide (13.7%), cis-β-farnesene (6.5%), 1-octen-3-yl-acetate (5.6%) and trans-caryophyllene (4.9%) were the major compounds. The volatile oil composition of L. vulgare collected from Iran (present study) was significantly different from that collected from elsewhere, indicating two possible chemotypes. The volatile oil showed free-radical-scavenging, antifungal and allelopathic effects.
