Abstract

Graphical abstract: Highlights: Two new sesquiterpenepolyol esters were isolated from Pseudolarix kaempferi . All known compounds were isolated from Pseudolarix genus for the first time. CD exciton chirality method was used to determine the absolute configuration of new compounds. Abstract: 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 compounds3 -16 were isolated from the Pseudolarix genus for the first time.
