摘要：
Composition comprises, in a medium, iridoid compounds (I) or their plant extracts, and at least one nucleophilic carbonyl compound or its optical or geometrical isomer, organic or mineral acid salt or solvate, where the compounds (II)-(V) optionally comprise an anion or mixture of anions to ensure electrical neutrality of the composition. Composition comprises, in a medium, iridoid compounds of formula (I) or their optical or geometrical isomers, or their mineral or organic acid salts, or solvates, or their plant extracts, where (I) optionally undergo a step comprising replacing the radical R with a hydrogen atom produced by an enzyme, prior to or simultaneously during the coloring of hair, and at least one nucleophilic carbonyl compound of formula (A1-C(=O)-C((R1b) 2)-C(=O)-B1) (II), (III), (IV) or (R25-O-C(=O)-CH 2-CN) (V) or its optical or geometrical isomer, organic or mineral acid salt or solvate, where the compounds (II)-(V) optionally comprise an anion or mixture of anions to ensure electrical neutrality of the composition, and are also from carbonyl oligomers or polymers comprising polymalonic acids or their esters, polysuccinic acids and/or sulfoacetic acid polymers. R1 : hydroxymethyl, -CO 2R4 or a sugar radical； R4 : H or 1-2C-alkyl； R2 : H, hydroxy or a sugar radical； R3 : H, hydroxy or 1-4C-alkyloxy, where the number of hydroxy groups is = 2； R : a sugar radical, where the sugar radical is a derivative obtained from an aldose or its derivative； n : 1-5； either A1 : A11-[C((R1a) 2)-C((R1a) 2)] n1-, A11a-[C(R1a)=C(R1a)] n1- or A22-O-； and B1 : B11-[C((R1a) 2)-C((R1a) 2)] m1-, B11a-[C(R1a)=C(R1a)] m1- or B22-O-； or A1+B1 : a 5- or 6-membered ring or heterocycle optionally comprising a heteroatom, preferably O, where the ring or heterocycle is optionally fused to a phenyl radical i.e. optionally substituted with at least one CH 3CO-, -COOR66 or -OCOR66； n1 : 0 or 1； m1 : 0 or 1； R1a : H or 1-4C-alkyl； either R1b : H or CH 3CO-, where one of the two radicals
