Abstract
The fractions extracted with methylene chloride from colored rice seeds of 19 cultivars were prepared to examine the correlationties of both antimutagenicity and antioxidiativity with physiological functionalities. The data revealed a positive correlation of the antimutagenicity with the content of $(3.{\beta},22Z)-Acetate-stigmasta-5,22-dien-3-ol$, 24-Oxocholesterol acetate, 6(E),8(E)-Heptadiene, and Eicosane. For antioxidativity, electron donating ability to DPPH radicals exhibited a positive correlation with the content of (24R,25S)-Aplysterylacetate, however, negative correlations were found between scavenging activity toward hydroxyl radicals and the content of either Tetradecanoic acid or Methyl ester-hexadecanoic acid, $(3.{\beta},24S)-Stigmast-5-en-3-ol$, respectively. In addition, a positive correlation was detected between the inhibitory effect of the fractions and the content of $(3.{\beta},24S)-Stigmast-5-en-3-ol$, however, a negative correlation with the content of 3',3'-Dimethylspiro [acridane-9,1'-indane], $(3.{\beta})-24-Methylene-9,19-cyclolanostan-3-ol$, and some other compounds was observed, respectively.
