Two new stilbenoid dimers, cajanstilbenoids A (1) and B (2), were isolated from the leaves of Cajanus cajan. Planar structures of these compounds were verified by NMR (1D and 2D) and high-resolution electrospray ionization mass spectroscopy (HR-ESI–MS). Absolute configurations were assigned by comparing experimental and calculated electronic CD values. The cytotoxicity of 1 and 2 against human hepatoma (HepG2), human breast adenocarcinoma (MCF-7), and human lung cancer (A549) cells were evaluate...

Objective: To study the chemical constituents from Periploca forrestii. Methods: The constituents were separated by column chromatography and their structures were elucidated by spectroscopic methods. Results: Seven compounds were isolated from Periploca forrestii and identified as wogonin( 1),negletein( 2),vanilline( 3),isovanilline( 4),periplocoside L( 5),β-sitosterol( 6) and β-daucosterol( 7). Conclusion: Compounds 1 and 2 are obtained from this genus for the first time,and compounds 3 ~ 5 ar...
