sapogenol artefact identified as 3β,22β,24-trihydroxyolean-18(19)-en and named soyasapogenol H. From a zanhic acid saponin two major artefact compounds identified as 2β,3β,16α-trihydroxyolean-13(18)-en-23,28-dioic acid and 2β,3β,16α-trihydroxyolean-28,13β-olide-23-oic acid were obtained, together with some zanhic acid. Other compounds, detected in very small amount in the reaction mixture, were also tentatively
紫花苜蓿皂苷酸水解过程中获得的人工制品化合物。(豆科),已通过 GC-FID 进行监测和评估。它们的鉴定已通过 GC-MS 和 1H 和 13C NMR 进行。考虑了在三萜五环苷元上具有不同取代基的皂苷,并在 10 小时的时程反应中检测和量化了它们的水解产物。从大豆皂甙 B、C、D 和 F 中获得众所周知的大豆皂甙 B、C、D 和 F,以及先前未描述的皂甙人工制品,鉴定为 3β,22β,24-trihydroxyolean-18(19)-en 并命名为 soyasapogenol H。来自 zanhic acid saponin鉴定为 2β,3β,16α-trihydroxyolean-13(18)-en-23,28-dioic acid 和 2β,3β,16α-trihydroxyolean-28,13β-olide-23-oic acid 的两种主要人工合成化合物被一起获得用一些山楂酸
