Abstract:
The variation in terpene composition of the leaf essential oil was studied in three populations of Valeriana officinalis L. subsp, collina. These populations grow in Italy in environmentally very different areas. Our examination of geographically and ecologically distant populations has provided evidence for substantial Iocal intrasubspecific differentiation. Statistical treatment of chemical data revealed two distinct chemical varieties of subspecies collina.
