Several fatty acids and derivatives were isolated from the dichloromethane extract of Angelica pubescens Maxim f. biserrata Shan et Yuan (Umbelliferae) by following in vitro 5-LOX and COX-1 inhibitory assays. Linoleic acid showed potent inhibition against PGE2 production from purified COX-1 enzyme. Falcarindiol, which is an acetylenic alcohol, showed higher potency against LOX than COX (Table 3) [122]. Linolenic acid is an... 

Several synthetic analogues containing only one triple bond were tested and demonstrated significant activity at levels <1 lg/ml [85]. Maximum activity was observed for compounds containing a ketone conjugated with a triple bond, aryl or an ester group. Falcarindiol (21), from the fresh roots of Angelica pubescens, was nematocidal to A. besseyi [69].
