Key Word Index - Thapsia villosa; Umbelliferae; roots; phenylpropanoids; hemanticine; guaianolides; thapsivillosin K. - Five phenylpropanoids related to hemanticine have been obtained from Thapsia villosa roots.We propose for these substances the trivial names isohelmanticine, neohelmanticine, isoneohelmanticine, epoxyhelmanticine and epoxyhelmanticine angelate.All these substances are based on (1S,2R)1-(3-methoxy-4,5-methylenedioxyphenyl)-1,2-propanediol, which is esterified variously by acetic, angelic, epoxyangelic and/or (2R,3S)2,3-dihydroxy-2-methylbutyric acids.We also report three C6-guaianolides and their hydrolysis products.The name thapsivillosin K is proposed for a new guaianolide.

Helmanticine, a new phenylpropanoid esterified by angelic and 2,3-dihydroxy-2-methylbutyric acids, was isolated from Thapsia villosa and its full structure established by spectroscopic methods and chemical transformations.Hydrocarbons, 12-nonacosanone, sitosterol and latifolone were also isolated. Key Word Index - Thapsia villosa; Umbelliferae; phenylpropanoids; helmanticine; latifolone; 12-nonacosanone.
