Abstract:
The purpose of this study is
to evaluate the anthocyanin (AC) and
phenolic compounds (TPC) content, and the
description of anthocyanin profile obtained
by HPLC-DAD technique (High-
Performance Liquid Chromatography -
Diode Array Detector), from hydroalcoholic
extracts of four varieties of sour cherry
(Prunus cerasus L.) grown in experimental
field of Research-Development Station for
Fruit growing Iași, Miroslava area. Were
also examined some physical-chemical
properties of fruits, variety Mocăneşti 16
showing the highest moisture content
(87.98%), titratable acidity (1.32 g
malic/100g acid) and ascorbic acid (12 mg /
100g). AC, determined by pH differential
method, had the highest value at Engleze
timpurii variety (176.2 ± 0.97 mg/100g) and
TPC, determined by the Folin-Ciocâlteu
colorimetric method, had the maximum
value at Mocăneşti 16 variety (446.89 ±
0.70 mg GAE/100g). Based on the
chromatograms obtained, were identified
four anthocyanins: cyanidin (cy)-3-
glucoside, cy-3-rutinoside, cy-3-
sophoroside, cy-3-glucosylrutinoside,
expressed as a percentage of anthocyanins
area. Anthocyanin profile obtained was not
similar in varieties examined, and the ratio
between anthocyanins differed from one
variety to another. The data obtained
confirm previous results on the sour cherries
anthocyanin profile and can be used in food
and pharmaceutical industry (functional
foods) and as a basis of comparison for
future studies.
