ECD exciton chirality method today: a modern tool for determining absolute configurations
Chirality, Volume 34, Issue 2, Page 333-363, February 2022., 2022 Abstract The application of the exciton chirality method (ECM) to interpret electronic circular dichroism (ECD) spectra is a well‐established and still popular approach to assign the absolute configuration (AC) of natural products, chiral organic compounds, and organometallic species. The method applies to compounds containing at least two chromophores

Larvicidal efficacy of Quassin against Culex quinquefasciatus.
The Indian journal of medical research, 1992 Crushed aqueous extracts of leaf, wood, bark and flowers of Quassia amara showed antilarval activity against C quinquefasciatus. Quassin has been identified to be the antilarval principle present in this plant and was effective against mosquito larvae at a concentration of 6 ppm. Quassin was present to the extent of 0.1 to 0.14 per cent (average 0.12%)
