Article

Phytochemical investigation of the roots of Taraxacum coreanum (Asteraceae) led to the isolation of two new sesquiterpenes, acetyldihydrotaraxinolide (2) and acetyltaraxinolide (4), together with two known sesquiterpene glycosides, 11β,13-dihydrotaraxinic acid (1) and taraxinic acid β-(6-O-acetyl)-glucopyranosyl ester (3). The structures of the isolated compounds were determined on the basis of spectroscopic analysis.
