Commercial digitonin has been separated into its components using high-performance liquid chromatography and centrifugal countercurrent chromatography. The individual glucosides have been identified by californium-252 plasma desorption mass spectrometry, occasionally supplemented by hydrolysis and analysis of the liberated sugars and aglycones. Mass spectra of commercial digitonin that have appeared in the literature are discussed in the light of their complex nature. A new glycoside of molecular weight 1035 is described and a structure proposed.
已利用高效液相色谱法和离心逆流色谱法将市售洋地黄皂苷分离成其组分。通过锎 - 252等离子体解吸质谱法鉴定了各个糖苷，偶尔还辅以对释放出的糖和苷元的水解及分析。根据文献中出现的市售洋地黄皂苷的质谱图的复杂性质进行了讨论。描述了一种分子量为1035的新糖苷并提出了其结构。
