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

Table 1

GLC analysis of methanolyzates of permethylated saccharides 1 and 2 isolated 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	1.03	1.25	2.60	3.89
Saccharide 2	1.03	1.26	2.67	3.96

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