Abstract
C29H40OIl.H20. Mr = 582.7, orthorhombic, P2121, a=9.663(5), b=11.723(1), c=25.626 (3) Å, Z=4, V=2902.9Å3, Dx=1.33 Mg m-3, λ(Cu Ka) = 1.5418 Å, µ = 0.9 mm-1, F(OOO) = 1248, T= 295 K, final R for 2273 observed reflections is 0.077. Cryptosin contains deoxygluccse, a steroid group and a lactone ring. The glucopyranose ring assumes a chair conformation. The steroid group shows the presence of an epoxy group unlike in other cardioactive compounds such as strophanthidin and digitoxigenin. The AlB and CID ring junctions are cis as in other cardioacuve steroids. Thc molecules pack in a network which contains three distinct hydrogen bonds.
