[Studies on chemical constituents of the gall of Python molurus bivittatus Schlegel].

Two constituents were isolated from the gall of Python molurus bivittus Schlegel, one is sodium taurodeoxycholate (I). The other is a new compound--sodium tauropythocholate (II). Its structure was elucidated as 3 alpha, 12 alpha, 16 alpha-trihydroxy-5-cholan-24-oic acid N-[2-sulfoethyl] amide by IR, 1HNMR, 13CNMR, MS 13C-1H COSY, and chemical reaction.
