Other constituents of the essential oil from the gum resin of F. assa‐foetida L. accounting on average for > 0.5% of the composition (based on the analysis of three batches) not included in the specification. 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%
