摘　　要：从黄花棘豆总皂苷的酸水解产物中分离出两种三萜皂苷元Ⅰ和Ⅱ,总皂苷经反复柱层析又得一微量三萜皂苷Ⅲ.本文报道它们的结构鉴定以及Ⅰ和Ⅱ的有关化学转变,用^(13)C NMR技术指定了Ⅰ和Ⅱ的^(13)C NMR信号.Two triterpenoid sapogenols Ⅰ and Ⅱ were obtained from the acidic hydrolysis products of the total saponin mixture of oxytropis ochrocephala bunge. Compound Ⅰ , the genuine sapogenol of the total saponin mixture, was identified as soyasapogenol B; compound Ⅱ , a new type artifact sapogenol, was determined to be olean-13(18)-ene-22a-chloro-33, 24-diol. We also isolated a minor saponin Ⅲ which was identified as 3-O-[β-D-glucopyranosyl(1→2)-β-D-glucuronopyranosyl] soyasapogenol B. This paper deals with the identification of compound Ⅰ , Ⅱ and Ⅲ , as well as the chemical transformations between them. The 13C NMR signals of compound Ⅰ and Ⅱ were also assigned by using 13C, 1H spin couplings and PRFT-13C NMR technique.
