Their structures were determined as neoline 14-O-a-and 14-O-b-L-arabinopyranosides（1 and 2） and 14-O-a-and 14-O-b-L-arabinofuranosides（3 and 4）, by spectroscopic and chemical methods including 2D NMR experiments and acid hydrolysis. Compounds 1–4 represent the first examples of glycosidic diterpenoid alkaloids.展开更多
