The isoflavonoid diphenol 3',7-dihydroxyisoflavan, an isomer of the known compound equol (4',7-dihydroxyisoflavan), has been identified in human urine and in cow's milk. The compound was isolated as the glucuronide, purified by column chromatography and identified after hydrolysis to the aglycon. The trimethylsilyl ether derivative was characterized by comparison of its mass spectrum and chromatographic properties with those of synthesized silylated isomers of equol.
异黄酮二酚3'，7 - 二羟基异黄烷，即已知化合物雌马酚（4'，7 - 二羟基异黄烷）的异构体，已在人尿和牛奶中被鉴定出来。该化合物以葡糖醛酸苷形式分离出来，通过柱色谱法纯化，并在水解为苷元后进行鉴定。通过将其质谱和色谱性质与合成的雌马酚硅烷化异构体的质谱和色谱性质进行比较，对三甲基硅醚衍生物进行了表征。
