Both Lamprocampnos and Corydalis are members of the Papaveraceae family, with seeds having an attached elaiosome that makes them attractive to ants, which disperse the seeds.
Yuanhunine is an anti-allergic compound isolated from Corydalis.
Corydalus (also transcribed corydalis) comes from the Greek (κορυδαλλις) meaning a crested lark or the flower, larkspur, apparently related to Greek corys (κορυς) a helmet crest.
