Chemical composition of Inula cuspidata C.B. Clarke

Abstract

1249-1253Thymyl isobutyrate, thymol, thymyl isovalerate, 8α-hydroxy presilphiperfolene and intermedeol have been isolated from steam volatile extract of Inula cuspidata and identified from their spectral data, synthesis and chemical modification of major constituents. Sharp qualitative and quantitative variations among the constituents of leaf, flower and roots of Inula cuspidata are noticed
