Strophanthi grati semen (1) is characterized by g-strophanthin (Tl) as the main compound at R 0.1, with smaller amounts of sarmentosides at Rf 0.25-0.4 and glycosides above and below g-strophanthin. Strophanthi kombd semen (2) contains the k-strophantin-glycoside mixture , which consists of k-strophanthoside (R, 0.05/T7), k-strophanthin 3 (R, 0.25/T3) and erysimoside (Rf 0.2/T4), They form major bands, while helveticoside (Rf — 0.55/T5) and cymarin (Rf — 0.6/T6) are minor compounds.
