Total antioxidant activity of several kinds of honey<br />

Honey kind TAS [mmol 100 g –1 ]<br />

linden 45.01 ± 0.51<br />

floral (whisked) 2007 26.86 ± 0.38<br />

floral (whisked) 2006 51.34 ± 0.61<br />

sunflower 55.76 ± 0.58<br />

rape (natural) 16.51 ± 0.31<br />

rape (pasted) 40.23 ± 0.50<br />

meadow (floral)<br />

(supermarket 1)<br />

22.31 ± 0.35<br />

forest (floral mixed)<br />

(supermarket 1)<br />

37.84 ± 0.49<br />

meadow (floral)<br />

(supermarket 2)<br />

16.20 ± 0.30<br />

forest<br />

44.61 ± 0.48<br />

(supermarket 2)<br />

thyme and herbal 55.04 ± 0.58<br />

acacia 16.73 ± 0.32<br />

royal jelly in honey 3,118.93 ± 11.02<br />

meadow (meadow flora) 21.99 ± 0.34<br />

eucalyptus 62.14 ± 0.67<br />

meadow 47.09 ± 0.44<br />

acacia 3<strong>3.</strong>28 ± 0.45<br />

orange flower honey 12.75 ± 0.29<br />

cereal 58.63 ± 0.55<br />

raspberry leaves 40.20 ± 0.42<br />

Floral – bee-keeper 146.68 ± 1.28<br />

honydew 137.49 ± 1.16<br />

Royal yelly 198.62 ± 1.33<br />

propolis 57,355.93 ± 300.42<br />

Ascorbate content ranged (0.65–4.65) mg100 g –1 . Content of<br />

hydroxymethyl furfural ranged (0.26–4.06) mg100 g –1 .<br />

By LC/MS method luteolin, naringenin, protocatechin<br />

acid, coffee acid and p-cumaric acid in honeydew were detected<br />

and, furthermore, kyanidin and pinocembrin in floral<br />

honey were found.<br />

Mono-floral honey contained biologically active compounds<br />

the most, imperceptibly less contained multi-floral<br />

honey and honeydew honey. Acacia honey contained the<br />

lowest amount of biologically active compounds.<br />

propolis 0.54 ± 0.01<br />

Conclusions<br />

According to our analytically obtained data there is<br />

no possible to say which kind of honey (meadow or forest)<br />

exhibited more beneficial health effect. It seems that honey<br />

quality is more significantly influenced by processing and<br />

storage conditions than by honey origin alone.<br />
