Title:
Flavanols in the nuclei of the tea bush (Camellia sinensis) -- broadening the perspectives to human health: Journal of Applied Botany and Food Quality; 86; 16-23 
Abstract:
Flavanols as a small subclass of the flavonoids stain selectively blue with the special reagent p-dimethylaminocinnamaldehyde (DMACA). Because of the prominent blue colour it is easy to recognize the flavanols histochemically in the vacuoles of expanding and maturing cells. However, the cells of the tea shrub (Camellia sinensis L.) show those blue coloured flavanols also in the nuclei. Silenced interphase nuclei of mature parenchyma cells indicate a pronounced diffuse distribution of blue staine...    »
