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

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

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*

*UC note that the paint replica gave a much lower recovery of arabic gum, as the sample weigh is dominated by the read led.
