title: Glycosides of 2-C-methyl-D-erythritol from the fruits of anise, coriander and cumin.
abstract: Eight glycosides of 2-C-methyl-D-erythritol (1) were isolated from the fruit of anise, and their structures were clarified as 1-O-beta-D-glucopyranoside, 3-O-beta-D-glucopyranoside, 4-O-beta-D-glucopyranoside, 1-O-beta-D-fructofuranoside, 3-O-beta-D-fructofuranoside, 4-O-beta-D-fructofuranoside, 1-O-beta-D-(6-O-4-hydroxybenzoyl)-glucopyranoside and 1-O-beta-D-(6-O-4-methoxybenzoyl)-glucopyranoside of 2-C-methyl-D-erythritol (2-9), respectively. Furthermore, 2 and 4 were isolated from the fruit of coriander, and 2, 3 and 4 were isolated from the fruit of cumin. Though the phosphate of 1 was known to be one of the first precursors of isoprenoids in the non-mevalonate pathway, and 1 is considered to be a common constituent in Umbelliferous plants, the glycosides of 1 are found for the first time.
