Yoritomo's Hunt by Torii Kiyomitsu I

Flavonoids フラボノイド: A group of organic colorant composed of heterocyclic aromatic compounds. For this database, a group of organic yellow colorants have been grouped under flavonoids due to this common chemical composition and difficulty in identifying them individually. Organic yellow colorants that have been thought to have been traditionally used in ukiyo-e prints that fall into this category are: Gardenia (Gardenia jasminoides) or (梔子 kuchinashi), Miscanthus tinctorius grass plant or (苅安 kariyasu), Mountain peach (Myrica rubra) or (山桃 yamamomo), Pagoda tree (Styphnolobium japonicum) or (槐 enju), and Toringo crabapple (Malus toringo) or (棠梨 zumi).

Flavonoids have been detected throughout the production of prints from 1690s through the 1860s. With current non-destructive analytical techniques, it is difficult to identify the exact source of each flavonoid. Flavonoids are duller and more beige when compared to the vibrant yellows produced by turmeric and orpiment. On prints, the dull appearance of flavonoids is little known since it can be their natural state or due to age and/or fading.

Analysis

Flavonoids, such as pagoda tree and kariyasu fluoresce weakly under ultraviolet radiation and have some differences in their EEM patterns. At this point, however, due to the difficulty in distinguishing these organic yellows, the decision was made to group them as flavonoids to minimize mistakes in identification.

Images of Flavonoids

Take photos of the other yellows to add.
