"//**Pimpinella saxifraga subsp. eusaxifraga**//: Because of the wide range of morphological variability and the unsatisfactory systematic division it seemed necessary to investigate the essential root oils from plants with simple segmented leaves and dissected leaves separately. Main constituent (about 60%) of the root oils from both forms is trans-epoxy-pseudoisoeugenyl-2-methylbutyrate. Furthermore, it is characteristic for these two oils that 1,4-dimethyl-azulene and its postulated precursors are only present in relatively low concentrations (totally about 5%). In a very few cases we could not at all establish the occurrence of 1,4-dimethylazulene in the volatile oils of roots from Pimpinella saxifraga subsp.eusaxifraga. Interestingly, the root oils of plants with simple segmented and dissected leaves also exhibit significant differences, mainly in the sesquiterpenes. | "//**Pimpinella saxifraga subsp. eusaxifraga**//: Because of the wide range of morphological variability and the unsatisfactory systematic division it seemed necessary to investigate the essential root oils from plants with simple segmented leaves and dissected leaves separately.
