Abstract:
This study aimed to provide information on the extraction yields, total
phenols, total flavonoids, antioxidant activity, and
qualitative-quantitative chemical composition of the extracts obtained from
the dried fruit of Sambucus racemosa L. with conventional solvents
(methanol, acetone, chloroform) and deep eutectic solvents (choline chloride
urea and choline chloride glycerol). Solid-liquid extraction, Folin-
Ciocalteu method, DPPH free radical scavenging, HPLC-UV/VIS were the methods
used in this study. The highest extraction yield (18%) was obtained with
ChCl:G as an extragent. The highest amount of total flavonoids was the
content of this extract (12.3 mg QE/g d.e.). Extracts obtained with acetone
and ChCl:U possess the highest amount of total phenol content (125.26 and
104.38 mg GAE/g d.e. respectively). All tested extracts showed free radical
scavenging activity. Identified components of extracts are gallic acid,
rutin, caftaric acid, caffeic acid, hyperoside, vitexin, and quercetin.
Fruit extracts of S. racemosa are a rich source of phenols and flavonoids.
The extracts obtained with DESs are more active in free radical scavenging
than those obtained with conventional solvents, and possess qualitatively
and quantitatively more components, apart from vitexin that was detected
only in the methanol extract.
