Abstract

The volatile oil of Polygonum alpinum L. (Polygonaceae) was prepered by hydrodistillation of flower, leaf and stem and characterized by GC and GC-MS. A total of 44,41 and 38 compounds were identified, constituting over 94.4, 96.3 and 97.2% of oil composition of the flower, leaf and stem of P. alpinum, respectively. Esters were shown to be the main group of constituents (flower: 46.2%, leaf: 59.1%, stem: 82.5%). The major components of the oils of R alpinum were ethyl hexadecanoate (flower: 11.7%, leaf: 15.0%, stem: 21.1%), methyl linoleate (flower: 30.7%, leaf: 11.7%, stem: 36.7%) and ethyl linoleate (leaf: 25.8%, stem: 14.7%). Terpenoids were the minor constituents in all parts (flower: 5.6%, leaf: 11.0%, stem: 6.4%) of the P. alpinum.
