Catalyzes the reduction of 2-phenylethylamine to produce 2-phenylethanol, a constituent of floral scent in petals. 2-phenylacetaldehyde + H(+) + NADPH = 2-phenylethanol + NADP(+) 2-phenylacetaldehyde + H(+) + NADH = 2-phenylethanol + NAD(+) Highly expressed in petals (PubMed:20650544). Expressed in calyxes and leaves (PubMed:20650544). Belongs to the NAD(P)-dependent epimerase/dehydratase family. Dihydroflavonol-4-reductase subfamily.
