Centaurea cyanus

It is also astonishing how the rich blue of a cornflower (Centaurea cyanus) and the majestic red flame of the com poppy (Papaver rheas) each derive from the same chromophore - again based on an anthrocyanidin. The pH of cornflower and poppy sap does not vary with soil composition, which explains why we see neither red cornflowers nor blue com poppies.

Despite the extensive traditional and current use of Hypericum in skin care and skin disorders targeted pharmacological studies related to these applications have rarely been performed. In a preliminary experimental study in human volunteers, equal quantities of hydroglycolic extracts from Calendula officinalis, Matricaria chamomilla, Anthemis nobilis, Tilia chordata, Centaurea cyanus and Hypericum perforatum were added at a 5 % level into the aqueous phase of 0.5 % hydrocortisone cream. When this preparation was applied to artificially induced skin abrasions, it was found that the plant extracts containing cream accelerated the healing time on an average of 16 % (3.4 days) versus the control [173). However, from this study no conclusions on the active ingredients and the mode of action can be drawn. 

Another alteration of imsaturated fatty acids is the formation of acetylenic groups (-C C-). This apparently occurs by dehydrogenation of -CH=CH-. Examples of naturally occurring acetylenes are crepen5mic acid (p. 381), alloxanthin (p. 1240), and the following remarkable hydrocarbon from the common cornflower Centaurea cyanus ... 

Cyanidin chloride 6 occurs in the petals of the cornflower (Centaurea cyanus). It forms dark-red needles, soluble in H2O but insoluble in diethyl ether or hydrocarbons. It is cleaved in molten potassium hydroxide giving phloroglucinol and 3,4-dihydroxybenzoic acid, a reaction which served to establish its structure.
