Three flavonoids were isolated from the leaf MeOH extracts of Primula latifolia Lapeyr. and Primula vulgaris Hudson collected from Italian Alps: rutin (1) and kaempferol 3-neohesperidoside (2) from P. latifolia, and kaempferol 3-β-O-glucopyranosyl-(1 → 2) gentiobioside (3) from P. vulgaris. The structures were assigned on the basis of their (1)H and (13)C NMR data, including those derived from 2D NMR, as well as on HPLC-MS results. This article is the first to report on P. vulgaris tissue flavonoids after Harborne's study in 1968 and the first work ever on these compounds from P. latifolia.
芦丁（1）和山奈酚 3-新橙皮糖苷（2）来自宽叶珍珠菜，以及来自欧洲报春花的山奈酚 3-β-O-吡喃葡萄糖基-（1 → 2）龙胆二糖苷（3）。结构基于它们的（1）H 和（13）C NMR 数据，包括来自 2D NMR 的数据，以及 HPLC-MS 结果。这是继 1968 年 Harborne 研究之后首次报道欧洲报春花组织中的类黄酮，也是首次对宽叶珍珠菜中的这些化合物进行研究。
