Abstract: | Summary From the seends ofCheiranthus allioni hort. another three cardiac glycosides have been isolated. One of them has been identified as cheirotoxin. It has been established that in cheirotoxin the D-glucose is attached to C4 of the D-gulomethylose and this glycoside therefore has the structure of strophanthidin 3 -O-4 -O- -D-glucopyranosyl- -D-gulomethylopyranoside]. The two other glycosides, which have been named sarmentogulomethyloside and gulosarmentoglucoside are new and are, respectively, sarmentogenin-3 -O- -D-gulomethylopyranoside and sarmentogenin 3 -O-4 -O- -D-glucopyranosyl- -D-gulomethylopyranoside].For Communication VIII see 1].Khar'kov Scientific-Research Institute of Pharmaceutical Chemistry.
