Antiproliferative cardenolides from Periploca graeca

Planta Medica, 2007
Nine cardiotonic steroids, six 17beta-cardenolides (2, 4, 6-9) and three 17alpha-cardenolides (1, 3, 5) have been identified from the chloroform and chloroform-methanol extracts of Periploca graeca L. (Asclepiadaceae) stems. Among these, compound 5, the 17alpha-isomer of periplocin 6, was identified as a new compound.

Cardenolides from the stem bark of Salacia staudtiana.

Fitoterapia, 2018
Seven new cardenolides, staudtianoside A-F (1-6) and staudtianogenin A (8), were isolated along with six known compounds from the stem bark of the Cameroonian medicinal plant Salacia staudtiana Loes. ex Fritsch. The structures were elucidated by means of

Glycosylation in cardenolide biosynthesis

Plant Cell, Tissue and Organ Culture, 1994
The glycosylation and deglycosylation of cardiac glycosides was investigated using cell suspension cultures and shoot cultures, both established from Digitalis lanata EHRH. plants, as well as isolated enzymes. Shoots were capable of glucosylating digitoxigenin, evatromonoside, digiproside, glucodigitoxigenin and digitoxin. Suspension cultured Digitalis

Alepposides, Cardenolide Oligoglycosides from Adonis aleppica

Journal of Natural Products, 1993
The structures of novel oligoglycosidic cardenolides, alepposide A (C55H86O23) [1] and alepposide B (C48H74O20) [2], have been deduced mainly by nmr methods. Based on homonuclear (1H and 13C nmr, 1H COSY) and proton-detected heteronuclear shift correlation experiments [HMQC both for 1J(C,H) and for long-range couplings], alepposide A [1] was shown to ...

Cardenolides ofSecurigera securidaca. II.

Chemistry of Natural Compounds, 1965
The seeds ofSecurigera securidaca have been found to contain a cardiac glycoside securidaside, which is securigenin xyloglucoside. By stepwise enzymatic hydrolysis, securidaside can be decomposed into the monoxyloside securiside or into the aglycone and the sugar component.

Saponins and Cardenolides

1998
Saponins are compounds that possess a polycyclic aglycone moiety with either a steroid (typically C27) or triterpenoid (C30) structure attached to a carbohydrate unit (a monosac-charide or oligosaccharide chain) (Fig. 24.1). These sugar units are composed variously of pentoses, hexoses, or uronic acids.
