Glimpse #5: Queraëlle GJ Red in honour of Mrs Gaëlle Van Merendonk (maiden name Pichon)

I’m going to a place where the love can thrive
I’m going to a place where the cancer dies
I’m going to a place where there is no shame
And I can feel no pain
Yeah, this is where I’ll stay
Cause I’ll be so much more than under oak trees”
Oak trees by Daniel Nunnelee

Daniel Nunnelee calls the song himself “my happy song about death”.

Today, lili would like to present lili’s new red complexes based on quercetin. Quercetin is found in oak trees (i.e. Quercus tentoria or quercus velutina or quercitron) and was imported to England by Bancroft around 1775 from America. The first documented extraction (Chevreul, 1829?) ¾according to L Rigaud in a temporary notice on the yellow colorant from the quercitron bark (in German) on 1853¾ was performed by boiling a yellow wood (quercitron?) with 10 parts of water for fifteen minutes. Then, yellow crystals (quercetrin?) were found after the extract was left standing for some days according to M. Chevreul. Mr Ragaud managed to mention the name Chevreul (without any further details) in the provisional and final publication on Quercetrin (in German) (L. Rigaud, 1854 ) one year later.

Lili wonder why Rigaud did downplay Chevreul’s work?…

Queraëlle GJ Red is named as a memorial to Gäelle van Merendonk, née Pichon, who was my first wonderful partner and the first who was asking for license agreements.
