CHEMOTAXONOMIC STUDY OF INULA L. (S.STR.) AND ITS ALLIED GENERA (INULEAE - COMPOSITAE) FROM PAKISTAN AND KASHMIR
RUBINA ABID AND M. QAISER
Abstract
Leaves of 21 taxa belonging to Inula L. (s.str.) and its allied genera viz., Pentanema Cass., Duhaldea DC., Dittrichia Greuter and Iphiona Cass., have been analyzed from Pakistan and Kashmir for their phenolic compounds. Analysis was carried out by two dimensional chromatography. Spectral analysis was performed on Shimadzu UV-spectrophotometer. The chemical data of this intricate group also support the generic delimitation of Dittrichia by having O-coumaric acid and Sakuranetin, while tricin 5-glucoside is exclusive for Iphiona and Duhaldea is distinctive by the presence of Vitexin and Isovitexin. However, Inula and Pentanema shared a mix pattern of compounds which points out the close relationship of both genera as compared to other genera of this group.
