decursin and falcarindiol

In this study, the anticholinesterase effects of the extracts and isolated compounds from the roots of endemic Prangos uechtritzii Boiss & Hausskn (Apiaceae) are reported. A novel polyacetylenic compound; (+)-8-O-methyloplopantriol A along with two known polyacetylenes; (-)-panaxynol, (+)-falcarindiol and fifteen known coumarin derivatives; umbelliferone, 6-formylumbelliferone, suberosin, 7-demethylsuberosin, (+)-ulopterol, tamarin, psoralen, imperatorin, (+)-oxypeucedanin, (+)-oxypeucedanin hydrate, (+)-oxypeucedanin methanolate, (+)-marmesin, (-)-prantschimgin, (+)-decursinol, and (-)-adicardin were isolated from the hexane (Pu-HE), chloroform (Pu-CE), and methanol (Pu-ME) extracts of P. uechtritzii roots. (-)-Panaxynol, (+)-falcarindiol, 6-formylumbelliferone, (+)-decursinol, and (-)-adicardin were obtained from the genus Prangos for the first time. (+)-8-O-Methyloplopantriol A inhibited both AChE (IC
