Fig. 9. Sugar and fatty acid compositions of components B and D-1.
Tri-methysilyl ether derivatives of the N-acetylated methyl glycosides and the fatty acid methyl esters obtained by methanol-HCl hydrolysis of purified components B and D-1 were separated by gas-liquid chromatography. Each peak was identified by comparison of its retention time with standards and by the fragmentation patterns observed during electron impact and chemical ionization mass spectrometry (not shown).
