Constituents of the essential oil from the aerial part of Cymbopogon flexuosus (Nees ex Steud.) Will. Watson, accounting for > 0.5% of the composition (based on the analysis of six batches) not included in the specifications. The content of each constituent is expressed as the area per cent of the corresponding chromatographic peak (% GC area), assuming the sum of chromatographic areas of all detected peaks as 100%
