Primula latifolia Lapeyr. and Primula vulgaris Hudson flavonoids / P.S. Colombo, G. Flamini, G. Fico. - In: NATURAL PRODUCT RESEARCH. - ISSN 1478-6427. - 28:19(2014 Jun), pp. 1641-1644. [10.1080/14786419.2014.924003]
Abstract:
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 1H and 13C 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.
