| 摘要 |
The invention relates to the use of specific compounds from the structural class of vanillyl lignans or the salts and/or mixtures thereof for modifying or masking unpleasant taste impressions, in particular bitter, astringent, and/or metallic taste impressions. The invention also relates to a corresponding method for masking unpleasant taste impressions, in particular bitter, astringent, and/or metallic taste impressions. The invention further relates to specific preparations containing an effective amount of vanillyl lignans or the salts and/or mixtures thereof to be used in accordance with the invention. |

1. A method for masking a bitter, an astringent, and/or a metallic taste of caffeine, theobromine, naringin, quinine hydrochloride dihydrate and/or salicin comprising combining the caffeine, theobromine, naringin, quinine hydrochloride dihydrate and/or salicin with one or more vanillyl lignans selected from the group consisting of:
(1-(−)) (−)-Matairesinol ((3R,4R)-3,4-bis[(4-hydroxy-3-methoxyphenyl)methyl[oxolan-2-one); (2-(−)) (−)-7-hydroxymatairesinol ((3R,4R)-4-[(S)-hydroxy-(4-hydroxy-3-methoxy-phenyl)methyl]-3-[(4-hydroxy-3-methoxyphenyl)methyl]oxolan-2-one); (3-(+)) (+)-lariciresinol (4-[[(3R,4R,5S)-5-(4-hydroxy-3-methoxyphenyl)-4-(hydroxy-methyl)-oxolan-3-yl]methyl]-2-methoxyphenol); (4-(−)) (−)-arctigenin ((3R,4R)-4-[(3,4-dimethoxyphenyl)methyl]-3-[(4-hydroxy-3-methoxy-phenyl)m-ethyl[oxolan-2-one); (5-(+)) (+)-isolariciresinol (1,2,3,4-tetrahydro-7-hydroxy-1-(4-hydroxy-3-methoxy-phenyl)-6-methoxy-2,-3-naphthalenedimethanol); (6-(−)) (−)-.alpha.-conidendrin ((3aR,9R,9aS)-7-hydroxy-9-(4-hydroxy-3-methoxyphenyl)-6-methoxy-3a,4,9,9a-tetrahydro-1H-benzo[f][2]benzofuran-3-one); (7-(−)) (−)-nortrachelogenin ((3S,4S)-3-hydroxy-3,4-bis[(4-hydroxy-3-methoxyphenyl)methyl]-oxolan-2-on-e); and (8-(+)) (+)-pinoresinol (4-[(3S,3aR,6S,6aR)-6-(4-hydroxy-3-methoxyphenyl)-1,3,3a,4,6,6a-hexahydro-furo[3,4-c]furan-3-yl]-2-methoxyphenol),
wherein the stereoisomer purity is greater than 50% relative to all the stereoisomers of the respective vanillyl lignin(s). |
