Isolation and Structural Analysis In Vivo of Newly Synthesized Fructooligosaccharides in Onion Bulbs Tissues (Allium cepa L.) during Storage

Table 2

GLC analysis of methanolyzates of permethylated saccharides 1 and 2 synthesized by purified from G-FFT from onion bulbs.

Methanolyzate from permethylated	Relative retention time*
	Methyl 1,3,4,6-tetra-O-methyl-D-fructoside		Methyl 3,4,6-tri-O-methyl-D-fructoside
Saccharide 1	1.04	1.25	2.59	3.86
Saccharide 2	1.03	1.26	2.66	3.94

* Retention time of methyl 2,3,4,6-tetra-O-methyl-β-D-glucoside = 1.
