An enzyme-linked immunosorbent assay for quassin and closely related metabolites
Analytical Biochemistry, 1984A microtitration plate enzyme-linked immunosorbent assay has been developed for quassin and closely related seco-triterpenes. The method is much more sensitive than conventional chromatographic techniques and enables the routine analysis of large numbers of samples with a detection limit of 5 ng quassin.

A thin-layer chromatographic method for the determination of “quassin” in cosmetic preparations
The Analyst, 1967A method is described by which “quassin” may be determined when used as a denaturant for the alcohol contained in cosmetic preparations. The two bitter principles, neoquassin and quassin are determined together as quassin, after oxidation with a solution of sodium dichromate in glacial acetic acid.

[Antiamebic properties of some derivatives of ailantone and quassin].
Il Farmaco; edizione scientifica, 1981Owing to its high toxicity, ailanthone, one of the most potent in vivo amoebicidal drugs of natural origin, cannot be safely employed in clinical trials. With the aim of obtaining a compound with a better therapeutic index and of studying possible relationships between biological activity and chemical structure, many derivatives of ailanthone and of ...
