title: Isolation and identification of two steroid compounds from Oviductus Ranae.
abstract: In this study, cholest-5-en-3β,7β-diol and 3β-hydroxy-cholest-5-en-7-one were isolated from Oviductus Ranae by column chromatographies on Sephadex LH-20, octadecylsilyl (ODS) and pre high-performance liquid chromatography (HPLC). Their structures were elucidated on the basis of chemical and spectral analyses, including electrospray ionisation-mass spectrometry (ESI-MS) and nuclear magnetic resonance (NMR). The above two compounds were obtained from Oviductus Ranae for the first time.
