  GC-FID and GC-MS analyses of methyl derivatives, MALD-TOF-MS measurements and NMR spectra were used to confirm the structural characteristics of the isomers. The (1)H and (13)C NMR signals of each isomer saccharide were assigned using COSY, E-HSQC, HSQC-TOCSY, HMBC and H2BC techniques. These kestose isomers were identified as α-D-fructofuranosyl-(2- > 2)-α-D-glucopyranosyl-(1 < ->2)-β-D-fructofuranoside

  通过碳-塞利特柱色谱法和HPLC从甜菜糖蜜中分离出八种KestOSe异构体。甲基衍生物的GC-FID和GC-MS分析，MALD-TOF-MS测量和NMR光谱用于确认异构体的结构特征。使用COSY，E-HSQC，HSQC-TOCSY，HMBC和H2BC技术分配每种异构体糖的（1）H和（13）C NMR信号。这些异构体被鉴定为α-D-果糖呋喃糖基-（2-> 2）-α-D-吡喃葡萄糖基-（1 <-> 2）-β-D-果糖呋喃糖苷，α-D-果糖呋喃糖基-（2-> 3 ）-β-D-果糖呋喃糖基-（2 <-> 1）-α-D-吡喃葡萄糖苷，α-D-果糖呋喃糖基-（2-> 4）-β-D-果糖呋喃糖基-（2 <-> 1）-α -D-吡喃葡萄糖苷，β-D-果呋喃糖基-（2-> 4）-β-D-呋喃呋喃糖基-（2 <-> 1）-α-D-吡喃葡萄糖苷，β-D-呋喃呋喃糖基-（2-> 3） -α-D-吡喃葡萄糖基-（1

  Fermented beverage of plant extracts was prepared from the extracts of approximately 50 types of vegetables and fruits. Natural fermentation was carried out mainly by lactic acid bacteria (Leuconostoc spp.) and yeast (Zygosaccharomyces spp. and Pichia spp.). Two oligosaccharides containing an alpha-fructofuranoside linkage were detected in this beverage and isolated using carbon-Celite column chromatography and preparative HPLC. The structural confirmation of the saccharides was determined by methylation analysis. MALDI-TOF-MS, and NMR measurements. These saccharides were identified as alpha-D-fructofuranosyl-(2 -> 6)-D-glucopyranose, which was isolated from a natural source for the first time, and a novel saccharide beta-D-fructopyranosyl-(2-6)-alpha-D-fructofuranosyl-(2 <-> 1)-alpha-D-glucopyranoside.
