- W1997452103 abstract "The distribution and concentration of two sesquiterpene lactones (I = niveusin C, II = 15-hydroxy-3-dehydrodesoxyfruticin) in different tissues of sunflower seedlings (Helianthus annuus L.) were investigated. A fast extraction method was developed. Quantitative analysis of these compounds in the nanomolar range was carried out using a high performance liquid chromatography (HPLC) technique. Both compounds were found mainly in leaves, with the greatest amounts in leaves close to the apex. The biosynthesis of the investigated sesquiterpene lactones (SQL) depends on light conditions and on the developmental stage of the leaves. The SQL content in leaves increased only during the first eight to ten days of leaf development. Within different individuals, the SQL content varied as much as 40% from the mean. When plants were grown under identical conditions, the SQL content of young leaves of seven distinct varieties of Helianthus annuus ranged from about 0.003% to 0.1% of the fresh weight. The function of these substances as a chemical defence mechanism of the plants against microbial infection and animal feeding is discussed." @default.
