“…Peak A had a calculated A S . value of 5.89 compared to 5.88 for cevacine and exhibited an infrared spectrum similar to that of authentic cevacine.The treatment of Peak B, Fraction I, from which sabadilline I was isolated has been described previously(2).The fractions which constituted Peak C(Fig. 1) were combined and yielded 159 mg. of crystalline -Countercurrent distribution of Peak A, Fraction I at pH 5.88 for 464 transfers us.…”
