Identification of two Stilbenoids from Vitis Roots.
Isolation and structural identification of two oligostilbenes from the roots of Vitis vinifera cv. Chardonnay is reported. The first compound, ampelopsin A, is a dimer of resveratrol and has been previously found only in the roots of Ampelopsis brevipedunculata var. hancei (Vitaceae). The second one, hopeaphenol, can be regarded as a dimer of ampelopsin A, and its presence in the Vitaceae is here reported for the first time. Both compounds are presented at grams per kg levels in vine roots.
