Abstract:
This study was intended to look for anti-HIV chemical constituents of aerial parts of
Caragana rosea Turcz. Column chromatographic technique was used for the isolation and purification of constituents of
Caragana rosea under the guide of anti-HIV assay. The structures were established on the basis of physical and chemical properties and spectroscopic data. Five compounds were obtained from the EtOAc fraction of aerial parts of
Caragana rosea and identified as myricetin (1), mearnsetin (2),
P-hydroxy cinnamic acid (3), cararosinol A (4) and cararosinol B (5). At the same time, one possible transformation route between cararosinol B and kobophenol A, another resveratrol tetramer isolated from this plant previously, was proposed. Compounds 4, 5 are new resveratrol tetramers, compounds 1-3 were isolated from this plant for the first time. All compounds showed no activities in an
in vitro assay against HIV-1.
