Subject:
alcohols; aldehydes; epicuticular wax; exine; free fatty acids; hydrocarbons; pollen; wax esters; wings
Abstract:
... “Epicuticular waxes” from pine pollen and from pollen wings have been investigated. Various hydrocarbons, aldehydes, wax esters, free fatty acids and primary alcohols in the form of homologous series were identified. A noteworthy observation was the presence of a large number of unsaturated fatty acids.Although there were quantitative differences between the waxes from whole pollen and pollen wing ...

Subject:
Paeonia; Rumex; Spinacia oleracea; color; flavonols; pigmentation; pollen
Abstract:
... Yellow coloration of pollen in some exceptional cases can be caused by the presence of intensely coloured flavonoids. Derivatives of herbacetin (sexangularetin) and of gossypetin (limocitrin) have been found as “yellow flavonols” in the pollen of some species of Paeonia and of Rumex. The pollen of Spinacea oleracea contains the 6-methyl ether of galetin and the quercetagetin derivatives patuletin ...
