New dammarane-type triterpene oligoglycosides, jujubosides A1 and C and acetyljujuboside B1 were isolated from Zizyphi Spinosi Semen, the seeds of Zizyphus jujuba MILL. var. spinosa Hu, together-with three known saponins. The structures of jujubosides A1 and C and acetyljujuboside B were determined on the basis of chemical and physicochemical evidence. Jujubosides A1 and C and acetyljujuboside B were found to inhibit the histamine release from rat peritoneal exudate cells induced by antigen-antibody-reaction.
从酸枣(鼠李科枣属植物酸枣的种子)中分离出了新的达玛烷型三萜寡糖苷——酸枣仁皂苷A1、C和乙酰酸枣仁皂苷B1,以及三种已知的皂苷。基于化学和物理化学证据确定了酸枣仁皂苷A1、C和乙酰酸枣仁皂苷B的结构。发现酸枣仁皂苷A1、C和乙酰酸枣仁皂苷B可抑制抗原抗体反应诱导的大鼠腹腔渗出细胞释放组胺。
