Antiscratching behavioral effects of the water extract of two black colored rice (BCR) varieties [Oryza sativa L. cv. Heugjinjubyeo (HJ) and Josaengheugchalbyeo (JH)], major pigment of which is cyanindin 3-glucoside, were investigated. Orally administered BCRs' extracts exhibited potent inhibitory activity against scratching behaviors which were induced by compound 48/80 and histamine. The inhibitory effect of Josaengheugchalbyeo in vivo and in vitro were more potent than those of Heugjinjubyeo. These finding suggest that black colored rice, especially Josaengheugchalbyeo, may inhibit scratching behaviors and anaphylaxis reaction by stabilizing membrane.

The anti-allergic effect of C3GHi rice breeded from the cross of 'Heugjinjubyeo' and 'Suwon 415' was investigated. Antiscratching behavioral effects of the water extract of C3GHi was higher than Heugjinjubyeo. Orally administered BCRs' extracts exhibited potent inhibitory activity against scratching behaviors which were induced by compound 48/80. The inhibitory effect of C3GHi against the passive cutaneous reaction was more potent than that of Heugjinjubyeo. These finding suggest that black colored rice, especially C3GHi, may inhibit scratching behaviors and passive cutaneous reaction, and its anti-allergic activities were increased by means of selecting high C3G rice seeds.
