Phytochemical investigation of Cassia multijuga seeds.
From the seeds of Cassia multijuga 1,3,8-trihydroxy-2-methyl anthraquinone, 1:3-dihydroxy 6,8-dimethoxy-2-methyl anthraquinone and two glycosides 3-hydroxy-6,8-dimethoxy-2-methyl anthraquinone-1-O-beta- D(+) glucopyranoside and 3-hydroxy 6,8-dimethoxy-2-methyl anthraquinone 1-O-rhamnopyranosyl (1 --> 6) glucopyranoside (rutinoside) have been isolated and their structures elucidated. The last three compounds are new and have not been isolated previously from any plant source.
