Aim:
To study the chemical constituents of the roots and stem bark of Kadsura coccinea.
Method:
Compounds were isolated by column chromatography on silica gel and Sephadex LH-20, and finally purified by prep-HPLC. Their structures were elucidated by extensive spectroscopic methods, including 1D- and 2D-NMR, and HR-ESI-MS.
Results:
Two compounds were determined as (7'S,8'S,8R)-(8β,8'α)-dimethyl-4,4'-dihydroxy-5,3'-dimethoxy-5'-cyclolignan glucoside (1) and micrandiactone H (2), respectively.
Conclusion:
Compunds 1 and 2 are new and neither showed inhibitory effects on nitric oxide (NO) production in lipopolysaccharide-induced RAW264.7 macrophages.
