11. Constituents: D. purpurea
It also contains primary and
secondary glycosides. Primary glycosides
are
Purpurea glycoside A (3 digitoxose,1glucose)
Purpurea glycoside B (3digitoxose, 1 glucose)
Glucogitaloxin.(3 digitoxose, 1 glucose)
Purpurea A and B are present in fresh leaves
12. • Digitoxigenin-------Purpurea glycoside A
• Gitoxigenin-------- Purpurea glycoside B
• Gitaloxigenin------Gluco-gitaloxin
D. lanata
• Digitoxigenin-------Lanatoside A
• Gitoxigenin----------Lanatoside B
• Gitaloxigenin--------Lanatoside E
• Digoxigenin------- Lanatoside C
• Diginatigenin-------Lanatoside D

14. • and on hydrolysis by the enzyme
digipuridase yield digitoxin and glucose or
gitoxin and glucose.
D. lanata
It also contains cardiac glycosides
like lanatoside A, B, C and E. Lanatoside A
and B are acetyl derivatives purpurea A and
B. On hydrolysis Lanatoside C yields
digoxin.
16. MEDICINAL USES
D.Purpurea
Used in chronic heart failure
Also used in the treatment of internal
hemorrhages, in inflammatory diseases , in
epilepsy and other diseases.
D lanata
has cardiac effect 3to 4 times greater than
purpurea.
Commercial source of digoxin
Used in the treatment of CHF
