[Isolation and identification of three steroid compounds from Mauremys mutics plastron].

ABSTRACT

OBJECTIVE: To investigate the steroids components from extract of Mauremys mutics. METHOD: The steroid compounds were isolated by using vacuum liquid chromatography and PTLC. The structures of three compounds were determined by spectral, chromatographic and chemical analysis. RESULTS: Three steroids were isolated from M. mutics and identified as cholesterol, elcosenoic acid cholesterol ester, cholester-4-ene-3-one. CONCLUSION: All the three compounds were isolated from M. mutics for the first time.
