Objective: To study the chemical constituents from Serissa japonica.
Methods: The constituents were isolated by various chromatographic techniques and their structures were determined on the basis of spectroscopic data,as well as literatures.
Results: Eleven compounds were obtained and identified as 3-hydroxy-1,2-dimethoxyanthraquinone( 1),1,2,4-trimethoxy-3-hydroxy-6-methyl anthraquinone( 2),emodin( 3),pinoresinol( 4),medioresinol( 5),( 7S,8R)-balanophonin-4-O-β-D-glucopyranoside( 6),lupeol( 7),icariside F2( 8),gallic acid( 9),methyl caffeate( 10) and 4-hydroxy-3-methoxyphenyl-β-D-glucopyranoside( 11).
Conclusion: Compounds 4and 5 are isolated from this plant for the first time,compounds 1 ~ 3 and 6 ~ 11 are isolated from Serissa genus for the first time.
