title: [Studies on the chemical constituents from the skin of Bufo bufo gargarizans Cantor].
abstract: Four bufotoxins were isolated by means of preparative reversed phase HPLC from the water soluble fraction of the skin of Bufo bufo gargarizans Cantor. On the basis of their spectral data (UV, IR, 1HNMR, 13CNMR, EIMS and FDMS), amino acid analyses and chemical properties, they were identified as bufotalin 3-succinoylarginine ester(I), bufalin 3-succinoylarginine ester(II), cinobufagin 3-succinoylarginine ester(III), and resibufogenin 3-succinoylarginine ester(IV). Compound I is a new bufotoxin.
