产品描述: 棘囊酸(ea)是一种天然三萜酸衍生物。报道了它在硒存在下的脱氢反应。据报道，它可以诱导人肝癌细胞系 hepg2细胞和人肝癌细胞系 hl-60的细胞程序性死亡早幼粒细胞白血病蛋白。由于其抗癌作用，广泛应用于草药中。Ea 在铬酸存在下进行氧化，得到3:12:16-三酮 -13- 羟基丙酸内酯。至今已有报告指出，洋葱的树皮和叶子都含有细菌。洋葱酸是羊乳的活性成分，在亚洲被用作食物和草药。 产品应用: 细粒棘囊酸(eea)可用于合成异核异氰酸根，在 kiliani 试剂的存在下经氧化反应合成。 Echinocystic acid (EA) is a natural triterpene acid derivative. Its dehydrogenation in the presence of selenium has been reported. It has been reported to induce programmed cell death in human HepG2 (human hepatocellular liver carcinoma cell line) cells and human promyelocytic leukemia cells (HL-60). Due to its anticancer action, it is widely used in herbal medicines. EA undergoes oxidation in the presence of chromic acid to afford lactone of 3:12:16-triketo-13-hydroxyoleananonic acid. EA has been reported to be present in the bark and leaves of Pithecellobium dulce. Echinocystic acid is an active component of Codonopsis lanceolata, which is treated as food and herbal medicine in Asia. Itis also found in fruits of Gleditsia sinensis. Product Application： Echinocystic acid (EA) may be used for the synthesis of isonorechinocystenedione, via oxidation in the presence of Kiliani′s reagent.
