Figure 1. ESI-MS (positive ion mode, Li+ adducts) analysis of the GlcCer species of S. apiospermum.

Figure 1

(A) MS1 spectrum. (B) ESI-MS2 of the ions species with m/z 734.9 observed in (A) and proposed structures for the major GlcCer species in S. apiospermum. (C) HPTLC plate of monosaccharides from S. apiospermum CMH. 1. Galactose, glucose, mannose and rhamnose standards; 2. Glucose from CMH. The sugars were detected using the orcinol-sulfuric acid spray reagent.
