Table 2 Sugar profile obtained from the paint replicas containing arabic gum and red lead using the procedure with and without ammonia extraction

From: Analysis of plant gums and saccharide materials in paint samples: comparison of GC-MS analytical procedures and databases

Sample Relative percentage content (%) Weight%
   xylose arabinose rhamnose fucose galacturonic acid glucuronic acid glucose mannose galactose  
paint replica with arabic gum and red lead without ammonia extraction 9 11 1 0 0 7 1 0 71 0.7*
  with ammonia extraction 0 34 15 0 0 12 0 0 39 1.4*
Reference arabic gum 0 26 13 0 0 12 0 0 49 65.2*
  1. *UC note that the paint replica gave a much lower recovery of arabic gum, as the sample weigh is dominated by the read led.
