摘要:
摘要 两种新的异戊二烯化氧杂蒽酮(garciniaxanthones A 和 B)与先前已知的氧杂蒽酮一起从 Garcinia subelliptica 的心材中分离出来。它们的结构是通过结合一维和二维核磁共振光谱和化学转化来建立的。Garciniaxanthone B 增强来自胎鼠半球的培养神经元细胞系统中的胆碱乙酰转移酶活性。
Abstract Two new prenylated xanthones, garciniaxanthones A and B, have been isolated from the heartwood of Garciniasubelliptica along with the previously known xanthones. Their structures were established by a combination of one- and two-dimensional NMR spectroscopy and chemical transformations. Garciniaxanthone B enhances choline acetyltransferase activity in a cultured neuronal cell system derived
