Abstract

Petal laminae in Silene pratensis (Rafn.) Godron et Gren, contain 60 to 80% of the flower flavonoids. The flavone content of the petal lamina on a fresh weight basis is about 10 times that of the petal claw and at least five times that of the calyx. The ratios between the different glycosides found in the stigmata or in the stamen usually differ from those in the rest of the flower. The highest flavone concentration is always found in the vacuoles of the epidermal cells in the most exposed parts of both leaves and the flower. The total flavone distribution pattern is not influenced by the type of glycosylation.

摘要

草原蝇子草（Rafn.）戈德隆和格伦的花瓣薄片含有60%至80%的花黄酮类化合物。以鲜重计，花瓣薄片中的黄酮含量约为花瓣爪的10倍，至少是花萼的5倍。在柱头或雄蕊中发现的不同糖苷之间的比例通常与花的其他部分不同。在叶片和花最暴露部分的表皮细胞液泡中总能发现最高的黄酮浓度。总黄酮分布模式不受糖基化类型的影响。
