title: Effect of variety on content of bioactive phenolic compounds in common elder (Sambucus nigra L.).
abstract: The inflorescence of common elder (Sambucus nigra L., Adoxaceae) is known to be rich in phenolic compounds. The content of five selected phenolic compounds (rutin, chlorogenic acid, isoquercitrin, isorhamnetin-3-O- rutinoside and dicaffeoylquinic acid) was determined in methanolic extracts from flowers and floral stems by HPLC in samples obtained from 20 varieties of S. nigra cultivated in Czech Republic. In all samples, there were determined rutin (11-54 mg/g), chlorogenic acid (23-46 mg/g), isoquercitrin (0.6-18 mg/g), isorhamnetin-3-O-rutinoside (3-10 mg/g), calculated on air-dried material. The content of dicaffeoylquinic acid was 0-13 mg/g of air-dried material. The amount of the analysed compounds in floral stems was lower than the flowers. The results are a unique set of information on the content of main phenolics in the inflorescence of cultured elderberry varieties.
