In 2011, a study was carried out on Iris halophila var. sogdiana and Iris halophila, to find the fat soluble constituents and volatility components. Using gas chromatography and mass spectrometry. (E,E) 9,12-octadecadienoic acid, methyl ester, 9-Octadecenoic acid(Z)-,methyl ester were found in both irises.
It is also known as Iris 'Halophila Sogdiana'.
It was commonly known as Iris sogdiana (before re-classification) or Ksiridion sogdiana (in Russia).
