calumbin

Cissampelina, the intensely sweetish-bitter principle found in this body, is very like calumbin in some physical properties; yet we have been wont to associate other therapeutic ideas with pareira, than with calumba.

1844, Richard Dennis Hoblyn, A Dictionary of Terms Used in Medicine and the Collateral Sciences:

It also contains bitter terpene-dilactones, such as calumbin and dihydronaphthalene (chasmanthin and palmanin).

Although catalyst IV also has good catalytic performance, it was totally soluble in the reaction system during and after the epoxidation, because it contains a big octadecyl benzyl dimethyl ammonium ion.

2001 May 11, Xi Zuwei et al., “Reaction-Controlled Phase-Transfer Catalysis for Propylene Epoxidation to Propylene Oxide”, in Science, volume 292, number 5519, →DOI, pages 1139–1141:

A 0.5-ml sample of the supernatant was put on a 6-ml activated, octadecyl solid-phase extraction cartridge (Bakerbond, J. T.
