 Title    Chemical Structure-Odor Correlation in Series of Synthetic Methylene Interrupted n-Nonadien-l-ols  
 Abstract    Chemical structure-odor correlations in the isomers of «-Cq-methylene interrupted dienols were explored using synthetic nine isomers of these alcohols. The synthetic dienols were purified by recrystallization or column chromatography of their 3,5-dinitrobenzoate de­ rivatives. Chemical structure-odor correlations in all the isomers of the purified «-nonadien-l-ols were analyzed by treating the data obtained statistically with the principal com ponent analy­ sis method (Sakoda et al., 1995; Cramer et al., 1988) in comparison with those of « -n on en -l-ols. The odor profiles of the /7-nonadien-l-ols were attributable largely to the geom etries of the isomers, compared with «-n on en -l-ols (Sakoda et al., 1995). With the principal com ponent analysis, the odor profiles of the series of the dienols were successfully integrated into the first and the second principal components. The first component (PC 1) consisted of combined char­ acteristics of fruity, fresh, sw eet, herbal and oily-fatty, and the second com ponent (PC 2) leaf or grassy and vegetable-like. O f the methylene interrupted dienol isomers, (2E ,6Z)-and (3Z,6Z)-nonadien-l-ols which are natural products and have (6Z) in the same, deviated markedly from the other isomers as seen in (6Z)-n on en -l-ol of n-nonen-l-ols. That suggests that the double bond of (oo3Z) was an important factor for natural characteristic odor.

 Title    Odor-Structure Relationships in n-Hexenols and n-Hexenais  
 Abstract    The relationships between the chemical structures and the odor characteristics were exam ­ ined on a series o f highly purified «-hexenols and «-hexenals (14 isomers). The C6-enals and the corresponding alcohols resembled in odor characteristics each other. However, the odor strength o f the aldehydes was 1 0 0 -1000 times higher than those o f the alcohols. In the princi­ pal com ponents analysis, the position o f carbon-carbon double-bond in the C6-com pounds was closely related to the scores o f the first principal com ponent, whereas the functional groups, hydroxy and formyl groups, were related to those o f the second principal com ponent except for (Z)-3-hexenol.
