Variation in essential oil content and composition ofRidolfia segetumMoris based on 30-hour prolonged fractionated extraction procedure
Natural Product Research(2020)
Abstract
A comprehensive study on essential oil samples extracted fromRidolfia segetumMoris (Apiaceae) collected in Tarquinia (Italy) is reported. In this study, a 30-hour, fractionated, steam distillation procedure for essential oil preparation was applied. The gas chromatographic-mass spectrometry analysis showed monoterpeneo-cymene and phenylpropanoid dill-apiol as the major essential oil's constituents revealing a new chemotype dependent on extraction duration. Great impact of the duration of the distillation process on chemical profile of essential oil was observed; prolonged distillation gives chemically more diverse essential oil samples. Preliminary microbiological evaluations of the essential oils samples revealed some activity, although not high, againstCandida albicans.
