The stems of Tinospora rumphii yielded clerodane type furanoidditerpene glucosides: the new rumphioside I, the known borapetosides C and F and three other compounds. Their structures were established on the basis of various spectroscopic techniques. The three compounds have physical and spectral data identical to those of the reported compounds borapetosides E, D and B, respectively. However, the
Tinospora rumphii 的茎产生了 clerodane 型呋喃类二萜葡萄糖苷:新的 rumphioside I、已知的硼烷甙 C 和 F 以及其他三种化合物。它们的结构是在各种光谱技术的基础上建立的。这三种化合物的物理和光谱数据分别与所报道的化合物硼烷甙 E、D 和 B 的物理和光谱数据相同。然而,前两种化合物的内酯环的位置以及将葡萄糖部分连接到第三种化合物的 C-6 的键的构型与报道的不同。
