An EtOH extract of the dried aerial parts of Ruta graveolens was suspended
in water and then partitioned with EtOAc. Three new glycosides, 3'-sinapoyl
-6-feruloylsucrose (4), methylenidioside A (5), and methylpicraquassioside
A (6), together with four known glycosides, 3',6-disinapoylsucrose (1), cni
dioside A (2), rutin, and picraquassioside A (3), were isolated from the wa
ter-soluble part. Their structures were elucidated by interpretation of IR,
MS, and 1D and 2D NMR spectra and comparison with literature data.
