Abstract
A new oligostilbene, caragasinin C (1), and seven known compounds, betulinic acid (2), 4-hydroxybenzaldehyde (3), (‒)-medicarpin (4), wistin (5), (2E,4S)-4-hydroxy-2-nonenoic acid (6), pallidol (7), and (+)-α-viniferin (8), were isolated from the roots of Caragana sinica. The structure of caragasinin C was established on the basis of spectroscopic techniques, including HRESIMS, 1D and 2D-NMR.
