Two new resin glycosides, cuses 3 (1) and 4 (2), were initially obtained from the seeds of Cuscutachinensis. Both of them contained a reducing glucose unit, and thus existed as a pair of isomers. In order to solve the existing problem of tautomerism, the remanent resin glycoside fraction was converted into aminoalditol derivatives with p-anisidine, and then another eight new resin glycosides cuses
