Abstract
This is the first study showing that alkaloids are present on the leaf surface of plants. A concentration of 30-230 pmol/cm2 pyrrolizidine alkaloids (PA's) was detected in 8 different samples taken from Senecio jacobaea. PA concentration on the leaves was marginally correlated with PA concentration of the total leaf tissues. The PA spectrum on the leaf differed from the PA spectrum of the total leaf.
摘要
这是第一项表明生物碱存在于植物叶片表面的研究。从千里光中采集的8个不同样本中检测到吡咯里西啶生物碱（PA）的浓度为30 - 230 pmol/cm²。叶片上的PA浓度与叶片总组织中的PA浓度呈微弱相关。叶片上的PA谱与叶片整体的PA谱不同。
