Naturally occurring 4'-dihydrophaseic acid (DPA) has been isolated from mature, non-imbibed bean seed. The concentrations of abscisic acid (ABA), phaseic acid (PA) and DPA in the seed were estimated to be 0.06, 0.11 and 5.95 mg/kg dry wt., respectively. The results suggest that DPA is a major inactivation product of ABA in this tissue. The possible pathway from ABA to DPA is discussed.
天然存在的 4'-二氢黄酸（DPA）已从成熟、未吸胀的豆种子中分离出来。种子中脱落酸（ABA）、黄酸（PA）和 DPA 的浓度分别估计为 0.06、0.11 和 5.95mg/kg 干重。结果表明，DPA 是该组织中 ABA 的主要失活产物。讨论了从 ABA 到 DPA 的可能途径。
