Out of these number of species, 96 were being studied for the first time. Fats and oils were found in all the species investigated comprising herbs and shrubs, (100% detection rate). Starch was not detected in any species, showing a zero persent detection rate. No correlation could be establisnhed between life form and the nature of ergastic substance in the Asteraceae.
