ABSTRACT
Background: Phytochemical investigation of hydroalcoholic extract of the root of Inula racemosa Hook. Materials and Methods: Open silica gel column chromatographic techniques with different solvent systems was used for isolation of aliphatic and eudesmalolide esters from hydroalcoholic extract of the root of Inula racemosa. The structure elucidation of the compounds was done on the basis of spectral data analysis, chemical reactions and comparision with literature data. Results: Phytochemical investigation of the hydroalcoholic extract of the root of Inula racemosa Hook. f. led to the isolation of (5z, 13z)-n-decanyl-n-docos-5, 13-dienoate, a new fatty acid ester, two new sesquiterpenic ester identifi ed as 15-[(13z, 18’z, 20’z)-n-tricos-13, 18, 20-trienyl]-eudesmal-4 (11), 6, 12 (13)-trien-8,14-olide-15-oate and 15- [(16’z), (21’z)-n- tetracos-16’, 21’-dienyl]-eudesmal-4 (11) 6, 12 (13)-trien-8, 14-olide-15-oate, two new eudesmanolide ester i.e. 15-[(16z)-n-monadec-16’-enyl]-eudesmal-4 (11) 6, 12 (13)-trien-8,14-olide-15-oate and 15-[(16’z)-n-tetracos-16’-enyl]-endesmal-4 (11), 6, 12 (13)-trien-8,14-olide-15-oate along with the known compound n-Hexadecanyl n-docosanoate. Conclusion: Five new phytoconstituents were identifi ed along with one known compound as aliphatic and eudesmalolide esters from the hydroalcoholic extract of the root of Inula racemosa, as mentioned above.
