Two New Sesquiterpenes from the Roots of Taraxacum coreanum
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.
