Anthocyanin pigments in strawberry

Lopes-da-Silva, M.F.; Escribano-Bailón, M.T.; Perez-Alonso, J.J.; Rivas-Gonzalo, J.C.; Santos-Buelga, Celestino

The anthocyanin composition was analysed in strawberry fruits from five different cultivars (cv. Eris, Oso Grande, Carisma, Tudnew and Camarosa). Twenty-five defined anthocyanin pigments were detected, most of them containing Pelargonidin (Pg) as aglycone; some cyanidin (Cy) derivatives were also found. Glucose and rutinose were the usual substituting sugars, although arabinose and rhamnose were also tentativel...

Flavanol-anthocyanin condensed pigments in plant extracts

González-Paramás, A.M.; Lopes-da-Silva, M.F.; Martin-Lopez, P.; Macz-Pop, G.; Gonzalez-Manzano, S.; Alcalde-Eon, C.; Perez-Alonso, J.J.

Pigments resulting from the direct condensation of anthocyanins and flavanols are usually associated with reactions taking place during processing and storage of plant-derived foods and beverages and have been particularly studied in aged red wines. In this paper, small amounts of flavanol-anthocyanin condensed pigments are found in different plant extracts. Structures are suggested for 10 such condensed pigmen...

Anthocyanin composition and related pigments in strawberry

Lopes-da-Silva, M.F.; Escribano-Bailón, M.T.; Martin-Lopez, P.; Rivas-Gonzalo, J.C.; Santos-Buelga, Celestino

The anthocyanin composition of the strawberry has been object of various studies, but it is still not fully characterized. It is well known the presence af pelarganidin 3 - glucoside (Pg 3 -gluc) as major anthocyanin, usually accompanied of smaller proportions of pelargonidin 3- rutinoside (Pg 3 -rut) and cyanidin 3-glucosid e (Cy. 3- gluc).

Identification of anthocyanin pigments in strawberry (cv Camarosa) by LC using ...

Lopes-da-Silva, M.F.; Pascual-Teresa, Sónia de; Rivas-Gonzalo, J.C.; Santos-Buelga, Celestino

New high performance liquid chromatography (HPLC) conditions were developed for the separation of strawberry anthocyanins that provided a good resolution of peaks at a low flow rate compatible with the requirements of the mass spectrometry (MS) detector. A strawberry extract was fractionated by column chromatography and simple fractions containing basically anthocyanins were obtained, making their analysis by H...
