Species of Capsicum L. genus are widely used by the human and known by their food
value, health-promoting properties and has cultivated in many countries (India, China, Japan,
Vietnam, Mexica, countries of Africa, South and Middle America, etc.).
Collection of chili peppers in the Botanical Garden of Slovak University of Agriculture in
Nitra created in 2017 and represented by 60 cultivars. In 2018 the collection contained
100 samples. 'Caroline Reaper' (C. chinense) one of the most impressive cultivar, which was
registered in the Guinness Book of Records. There are many interesting cultivars among
which 'Aji Charapita' that is added to soups. One kilogram of this spice has cost 35 000 dollars.
The spices has strong fruit aroma and is an ingredient of souses (as powder).
In this research represented results of study of antioxidant capacity of selected cultivars
of Capsicum species (Capsicum annum L., C. baccatum L., C. chinense Jacq.) from experimental
collection of Botanical Garden of Slovak Agricultural University in Nitra. For experiment
chosen 28 samples and dried at the 35 С for 36 hours. Crushed samples (200 mg) extracted
o
in 20 ml of 80 % ethanol for 2 hours at the constant stirring. After filtration obtained extracts
used to determine total content of polyphenols (TCP), total content of phenolic acids (TCPA),
total content of flavonoids (TCF). Antioxidant activity determined by both DPPH scavenging
activity (DPPH) and reducing power of extracts (RP).
Obtained data demonstrated that TCP was in range from 10.13 (С. baccatum, Aji Fantasy
Sparkly White) to 38.69 (C. baccatum, Habanero Red Savina) mg GAE/g DW, TCPA was in
range from 2.24 (С. baccatum, Aji Fantasy Sparkly White) to 13.71 (C. chinense, Fatalii Red) mg
CAE/g DW, flavonoids from 5.73 (С. baccatum, Aji Fantasy Sparkly White) to 27.32
(C. baccatum, Habanero Red Savina) mg QE/g DW. Antioxidant activity by DPPH method was
from 1.45 (C. chinense, Habanero Chocolate) to 8.21 (C. chinense, Fidalgo Roxa) mg TE/g DW
and reducing power of extracts had values from 24.81 (C. annuum, Black Prince) to 198.21
(C. baccatum, Habanero Red Savina) mg TE/g DW.
This study demonstrated that varieties of Capsicum annum, C. baccatum, C. chinense are a
valuable source of antioxidants of phenolic nature. They have significantly different values of
phenolic compounds and their antioxidant activity. Results of research support the use of
different investigated cultivars for functional food production and pharmacology.

Keywords: chili peppers, antioxidant activity, polyphenols.
