用柱层分离刺五加中糖苷类化合物,得到了 B 和 B_1的结晶,并测定了它们在紫外光区的吸收光谱。用 TLC 比较了刺五加不同部位中糖苷组分,并测定了 B 和 B_1的含量。结果表明,茎皮中各种糖苷类组分及 B 和 B_1的含量与根皮基本相同。 Columns were used to separate the glycosides of Acanthopanax senticosus, and the crystals of B and B_1 were obtained, and their absorption spectra in the ultraviolet region were determined. TLC was used to compare the glycosides in different parts of Acanthopanax senticosus and the contents of B and B_1 were determined. The results showed that the contents of various glycosides and B and B_1 in bark were basically the same as those of root bark.
