Aromadendrin (aromodendrin or dihydrokaempferol) is a flavanonol, a type of flavonoid. It can be found in the wood of Pinus sibirica.^[1]

Metabolism

The enzyme dihydrokaempferol 4-reductase uses cis-3,4-leucopelargonidin and NADP⁺ to produce (+)-aromadendrin, NADPH, and H⁺.

Glycosides

(2R,3R)-trans-Aromadendrin-7-O-beta-D-glucopyranoside-6′′-(4′′′-hydroxy-2′′′-methylene butanoate) is an acylated glucoside of aromadendrin isolated from the stem bark of Afzelia bella^[2] (Fabaceae).

Phellamurin is the 8-prenyl 7-glucoside derivative of aromadendrin.

Chemistry

(+)-Leucopelargonidin, (2R,3S,4R)-3,4,5,7,4'-pentahydroxyflavan, can be synthesized from (+)-aromadendrin by sodium borohydride reduction.^[3]
