Nine fructose-derived carbohydrates were obtained from the methanol extract from the rhizome of Alisma orientalis. On the basis of spectroscopic analysis, their structures were determined to be α-D-fructofuranose (1), β-D-fructofuranose (2), ethyl α-D-fructofuranoside (3), ethyl β-D-fructofuranoside (4), 5-hydroxymethyl-furaldehyde (5), sucrose (6), raffinose (7), stachyose (8) and verbascose (9), along with two oligosaccharides of manninotriose (10) and verbascotetraose (11). Compounds 3, 4 and 7-11 were isolated from this plant for the first time. A hypothetical biosynthesis pathway among these isolated carbohydrates (1-11) was briefly introduced.
