本酶催化的反应为7-[beta-D-Apiofuranosyl-(1->6)-beta-D-Glucopyranosyloxy]isoflavonoid + H2O = A 7-Hydroxyisoflavonoid + beta-D-Apiofuranosyl-(1->6)-D-Glucose，系统名称为7-[beta-D-Apiofuranosyl-(1->6)-beta-D-Glucopyranosyloxy]isoflavonoid beta-D-Apiofuranosyl-(1->6)-D-Glucohydrolase，来自热带树木 Dalbergia nigrescens Kurz（黄檀属）的该酶属于糖苷水解酶家族1。该酶从天然底物dalpatein 7-O-β-D-呋喃芹菜糖基-(1->6)-β-D-吡喃葡糖苷和7-羟基-2',4',5',6-四甲氧基-7-O-β-D-呋喃芹菜糖基-(1->6)-β-D-吡喃葡糖苷（dalnigrein 7-O-β-D-呋喃芹菜糖基-(1->6)-β-D-吡喃葡糖苷）上去除二糖，但它也能从异黄酮类7-O-葡糖苷上去除单个葡萄糖残基[2]。黄豆苷和染料木苷也是底物。
