THE PREGNANE GLYCOSIDE MARSDEKOISIDE A FROM MARSDENIA KOI

A new pregnane glycoside, mardekoiside A was isolated from the stems of Marsdenia koi (Asclepiadaceae) and its structure was elucidated from chemical and spectral data as 12-cinnamoyl-dihydrosarcostin-3-O-methyl-6-deoxy-β-D-allopyranosyl-(1->4)-O-β-D-oleandropyranosyl-(1->4)-O-β-D-cymaropyranoside. Key words: Marsdenia koi; Asclepiadaceae; preganane glycoside; marsdekoiside A; structure elucidation.

PREGNANE GLYCOSIDES FROM BOUCEROSIA AUCHERIANA

Ten glycosides named bouceroside-ANC, -ADC, -ANO, -ADO, -BNO, -BDO, -BNC, -BDC, -CNO and -CNC were isolated from Boucerosia aucheriana and their structures deduced on the basis of the chemical and spectral evidence.The absolute configuration of cymarose, which was obtained by acidic hydrolysis of seven of the glycosides, was determined by means of HPLC analysis of its carbamoyl derivative on a chiral column as D cymarose.
