从紫锥菊干根正己烷萃取物中分离得到11种异丁酰胺。十一烷-2 E， 4 E -二烯-8,10-二甲酸异丁酰胺是一种新化合物。根和草本成分的亲脂性谱与先前在紫荆和刺叶中发现的酰胺谱相似。然而，土刺草根的极性成分和地上部分似乎与紫荆草和刺荆草有很大的不同，因为没有发现菊苣酸和刺荆草苷。
Eleven isobutylamides have been isolated from the n -hexane extract of the dried roots of Echinacea atrorubens Nutt. Undeca-2 E, 4 E -dien-8,10-diynoic acid isobutylamide represents a new compound. The lipophilic profiles of constituents of the roots and the herb were similar as the alkamide profiles previously found in E. purpurea and E. angustifolia. The polar components of E. atrorubens roots and the aerial parts, however, seem to be very different from E. purpurea and E. angustifolia, since neither cichoric acid nor echinacoside could be found.
