Hippulin , also known as Δ8 -14-isoestrone , as well as 14-isoestra-1,3,5(10),8-tetraen-3-ol-17-one , is a naturally occurring estrogen found in horses and an isomer of equilin .[ 1] [ 2] [ 3] [ 4] The compound, likely in sodium sulfate form, is a component of conjugated estrogens (Premarin), a pharmaceutical extract of the urine of pregnant mares ,[ 1] [ 2] [ 3] though it is present only in small amounts in pregnant mare urine.[ 5] It has been reported by possess either equivalent estrogenic activity to that of equilin or only slight estrogenic activity.[ 3] The compound was first described in 1932.[ 4] [ 3]
