Abstract:
A new sesquiterpenoid, 10α-methoxyartemisinic acid (1) was isolated from Saussurea lappa roots along with two known compounds, costunolide (2) and dehydrocostus lactone (3) by high-speed countercurrent chromatography with purities of 85, 95 and 98%, respectively. Their structures were determined on the basis of spectral data including 1D and 2D NMR and HREIMS.
