Two novel anthocyanins, delphinidin 3-O-(6-O-(2-O-acetyl-α-rhamnopyranosyl)-β-glucopyranoside) and delphinidin 3-O-(6-O-(3-O-acetyl-α-rhamnopyranosyl)-β-glucopyranoside), were identified from the anthers of Tulipa gesneriana. These and delphinidin 3-O-(6-O-(α-rhamnopyranosyl)-β-glucopyranoside) made up over 80% of the anthocyanin content in the dark purple anthers and could be responsible for t...

The metabolism in vitro of [1-(14)C]linoleate, [1-(14)C]linolenate and their 9(S)-hydroperoxides in tulip (Tulipa gesneriana) was found to be under the control of 9-lipoxygenase and allene oxide synthase, and directed towards alpha-ketol, gamma-ketol and the novel compound (12Z)-10-oxo-11-hydroxy-12-octadecadienoic acid (10,11-ketol). Potent activity of allene oxide cyclase (in bulbs) and a new...
