New sesquiterpene polyol esters from the root bark of Pseudolarix kaempferi

Publication date: September 2016 Source:Phytochemistry Letters, Volume 17 Author(s): Hai-Long Jiang, Wei Ha, Jun-Li Yang, Yan-Ping Shi A series of sesquiterpene polyol esters, including two new β-dihydroagarofuran sesquiterpenes (1-2) and 14 known compounds (3-16), were isolated from the root bark of Pseudolarix kaempferi. The esters’ structures were elucidated by employing extensive spectroscopic analyses and by comparison to literature compounds. The absolute configurations of the two new compounds were determined by the CD exciton chirality method. The known compounds 3-16 were isolated from the Pseudolarix genus for the first time.
