MASS SPECTRUM OF GLYCOSIDES OF ECDYSTEROIDS AND THEIR PERACETATES

Mil'grom, Yu. M.,Rashkes, Ya. V.,Sadovskaya, V. L.,Saatov, Z.

, p. 193 - 197 (1991)

Features of the fragmentation of the carbohydrate chains of galactopyranosides of ecdysteroids (sileneosides A-D) and their peracetates under electron impact are discussed.The migration of Gal and AcGal residues from C-22 to C-20 has been detected.The secondary-ion mass spectra of the sileneosides using liquid matrices are considered.
