Abstract

PURPOSE:To obtain a yield-increasing agent capable of remarkably increasing the yield of various crops such as vegetables, fruits and cereals by using naringenin (a kind of flavonoid) and its 7-O-glucoside as an active component. CONSTITUTION:A yield-increasing agent for crop is produced by using naringin, naringenin, naringenin monoglucoside or naringenin transglucoside expressed by formula I (A is rhamnoglucoside, H, monoglucoside or polyglucoside). The compound of formula I wherein A is rhamnoglucoside (RG), i.e., glycoside naringin of formula III is present in the flower peel of shaddock and is separable by extraction. Another compound of formula I wherein A is H, i.e., naringenin of formula III is produced by extracting raw bark of peach tree or by hydrolyzing naringin of formula II with a dilute acid. A compound of formula I wherein A is monoglucoside (G), i.e., naringenin monoglucoside of formula IV can be produced from naringin of formula II. The compound of formula V can be derived from the compound of formula IV.
