Eighteen compounds including new caryophyllene-type sesquiterpene and flavonol tetraglycoside were purified and isolated from sword beans (Canavalia gladiata). Two new compounds, (Z,1R,7S,9S)-7-hydroxy-11,11-dimethyl-8-methylenebicyclo[7.2.0]undec-4-ene-4-carboxylic acid (2) and kaempferol-7-O-α-L-dirhamnopyranosyl(1 → 2;1 → 6)-O-β-D-glucopyranosyl(1 → 2)-O-α-L-rhamnopyranoside (9), were identified. Other known compounds including Me gallate (1), (2S,3S,4E,8E)-2-aminooctadeca-4,8-diene-1,3-diol 1-O-β-D-glucopyranoside (3), (2S,3S,4E,8Z)-2-aminooctadeca-4,8-diene-1,3-diol 1-O-β-D-glucopyranoside (4), lupeol (5), trilinolein (6), 1,6-di-O-galloyl β-D-glucopyranoside (7), N-(2-methoxybenzoyl)homoserine (8), dihydrophaseic acid (10), dillenetin (11), kaempferol-7-O-[2-O-β-D-glucopyranosyl-6-O-α-L-rhamnopyranosyl]-α-L-rhamnopyranoside (12), canavalioside (13), kaempferol-3-O-[2-O-β-D-glucopyranosyl-6-O-α-L-rhamnopyranosyl]-β-D-glucopyranoside (14), kaempferol-3-O-(2,6-O-α-L-dirhamnopyranosyl)-β-D-glucopyranoside (15), kaempferol-3-O-rutinoside (16), gladiatoside A1 (17), and gladiatoside B1 (18) were identified. The chem. structures of these compounds were determined by ESI-MS and NMR analyses. In the experiment, the researchers used many compounds, for example, rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1Application of 54-17-1)
rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1) is the monohydrate form of the alpha isoform of D-glucopyranose, a synthetic simple monosaccharide that is used as an energy source.Application of 54-17-1
