Isolation of a New Phenolic Compound, 3, 5-Dihydroxy- 2-(Methoxycarbonylmethyl)phenyl 3, 4-Dihydroxybenzoate, from Leaves of Actinidia chinensis (Kiwifruit)

Abstract:
Extraction of leaf tissue from the golden–fleshed kiwifruit cultivar Actinidia chinensis `Hort16A` expressing genotype–resistance against the fungus Botrytis cinerea revealed the presence of a novel phenolic compound, 3,5–dihydroxy–2–(methoxycarbonyl-methyl)phenyl 3,4–dihydroxybenzoate (1). In addition, the known phenylpropanoids, caffeic acid (2) and quercetin (3) were amongst the principal compounds present in a fungi–toxic phenolics extract from `Hort16A` leaf tissue. TLC fungi–toxicity bioassays indicated that 100 μg quantities of these pure compounds were not fungi–toxic, but caffeic acid is a central compound in the phenylpropanoid pathway and therefore might function indirectly in host resistance, by acting as a pre–cursor of fungi–toxic secondary metabolites. The other compounds could possibly act in a similar role.
