1890 J. S. Billings National Med. Dict. II. 338/1 Picrotoxinin, according to Barth and Kretschy, one of the constituent principles of picrotoxin.

1918 Jrnl. Amer. Chem. Soc. 40 1937 It is also perhaps interesting to note the natural occurrence of a series of lactones, corresponding to..the various terpene series. Sesquiterpenes, C₁₅H₂₄... C₁₅H₁₈O₃ Santonin... C₁₅H₁₆O₆ Picrotoxinin.

1952 Jrnl. Amer. Chem. Soc. 74 3046 The unique relationship of picrotoxinin to the steroid family is pointed out.
