  Composition of lipids from sunflower pollen (Helianthus annuus)

  摘要：

  The contents of the pollen lipids of the sunflower Helianthus annuus are described. The major component is the seco-triterpene helianyl octanoate, followed by new beta-diketones as second major group of compounds. They exhibit a shorter chain length and often other positions of the functional group compared to already known beta-diketones. Of particular note are the 1-phenyl-beta-diketones. not previously reported from nature. Further lipid classes present are related hydroxyketones and diols. Interestingly, new beta-dioxoalkanoic acids are present in the extracts. which most likely are biogenetic precursors of the diketones. Additionally, we investigated the composition of the pollen coat which resembles the total extract, but lacks the dioxoalkanoic acids and certain estolides. (C) 2000 Elsevier Science Ltd.

  A method for synthesizing beta-dicarbonyl compounds, particularly beta-diketones, from at least two carbonyl compounds, such as esters and ketones, in the presence of a strong base or a mixture of strong bases by Claisen condensation with a titer of greater than 95%. The method includes providing a synthesis reactor on which a separation column, provided with a condenser and with at least one microwave generator, is mounted; feeding a first carbonyl compound and the strong base into the synthesis reactor; heating the reactor and starting up the condenser; starting up the microwave generator(s); when the mixture is brought to a boil at total flux, feeding the second carbonyl compound into the reactor; and after a waiting time, stopping the reactor and acidifying and washing the reaction mixture.)
