A number of the flavones found in " S . lateriflora " have been reported to selectively bind with high affinity to central benzodiazepine receptor sites, leading to the view that the flavones exert anxiolytic and other benzodiazepine effects in rats.

Chemically, quercetin is a member of a fairly extensive class of natural coloring matters derived from phenyl benzoyl-pyrone or flavone, the constitution of which followed on the researches of St von Kostanecki, A . G . Perkin, Herzig, Goldschmidt and others.

Natural dietary flavones, found in parsley, celery, and citrus peels, reactivate DLC1 expression in breast cancer cell lines which have decreased DLC1 expression due to promoter hypermethylation, and may potentially be used as an anti-cancer agent for prevention and therapy of breast and other DLC1 downregulated cancers.

The results of these researches are published in upwards of 60 papers in the'Journal of the Chemical Society .'Partly in conjunction with the late Prof J J Hummel he investigated morin, apinin, quercitin, and other flavone compounds, he discovered and investigated curious compounds which such dyestuffs forms with acids.

"' Vitexin "'is an apigenin flavone glucoside, a chemical compound found in the passion flower, " Vitex agnus-castus " ( chaste tree or chasteberry ), in the " Phyllostachys nigra " bamboo leaves, in the pearl millet ( Pennisetum millet ), and in Hawthorn.

These scales give butterfly wings their colour : they are pigmented with melanins that give them blacks and browns, as well as uric acid derivatives and flavones that give them yellows, but many of the blues, greens, reds and iridescent colours are created by structural coloration produced by the micro-structures of the scales and hairs.
