Four kinds of honey from acacia, bush clover, chestnut and polyflowers were anlayzed for 9 minerals including sodium/potassium ratio, and ash content. The ash content ranged from 0.11 to 0.24% with the mean of 0.16% as potassium was found in higher concentration than other minerals. Chestnut honey had a greater quantity of mineral than others and the lowest value of sodium/potassium ratio. The correlation coefficient of $r=0.582^{**}$ was obtained for potassium and sodium. Potassium and sodium had also a high positive correlation with calcium, magnesium, iron and manganese.

The rheological properties of seven mixed sugar solutions of glucose, fructose, maltose, sucrose, and two kinds of honey, the chestnut and the acacia, were discussed. The fluidity of the above samples were studied by using the applied pressure horizontal viscometer with which glycerine was confirmed to be a Newtonian flow at $25^{\circ}C$. Time required to pass the constant volume of the sample fluids through the capillary was measured at various pressure differences, ${\Delta}p$, and the ${\Delta}p$ vs ${\Delta}p{\cdot}t$ in the Poiseuille equation was plotted. Shear rate against shearing stress, on the other hand, was plotted for the sample fluids and it was found that all the sample fluids have shown a Newtonian behavior. It was interesting to note that the shear viscosity increased as the concentration of sugar solutions increased, and as the concentration of sucrose became higher than that of maltose, although the total concentration of sugar solution is constant.

This study was conducted to investigate the contents of lead (Pb) and cadmium(Cd) in honeys (n=60) from April to May in 2004 and to provide the scientific basis for heavy metal regulations of Korea Food Code. The samples were digested with acids, then analyzed for the contents of Pb and Cd by an inductively coupled plasma spectrometer (ICP). The contents of Pb and Cd [minimum-maximum (mean)] were 0.189-1.82 mg/kg (0.568) and not detected (ND)-0.016 mg/kg (0.0008) in domestic acacia honeys (n=20), ND-1.702 mg/kg (0.329) and ND-0.243 mg/kg (0.013) in domestic wild flower honeys (n= 18), ND-0.322 mg/kg (0.073), ND-0.027 mg/kg (0.002) in imported honeys (n=13), ND-3.754 mg/kg (0.671) and ND-0.658 mg/kg (0.073) in foreign honeys (n=9) brought by Korean travellers, respectively. According to the results, foreign honeys brought by Korean travellers were detected with the highest level of Pb and Cd. Therefore, we recommend that heavy metals of domestic and foreign honeys should be continuously monitored. It is also thought that these results could be the important references to establish the standard of Pb and Cd in honey.

This study analyzed the total polyphenol (TP), total flavonoid (TF), and protein content, the Absorbance at 400 nm (A400), and the antioxidant and hemolytic activities of 150 Korean honey products, including 41 chestnut (CH), 42 acacia (AH), 62 multi-floral (MH), and five Styrax japonica (TH) varieties. Our results showed that the components and antioxidant activities of honey are dependent on botanical origin rather than farming area or farmer. CH showed the highest levels of TP (88.6±29.8 mg/100 g) and TF (1.20±0.82 mg/100 g), whereas TH had the highest protein (21.5±5.1 mg/100 g). A400 was the highest in CH (0.161±0.044). All of the honey products exhibited negligible hemolytic activity against human red blood cells up to 1 mg/ml. Potent radical scavenging activities for 1,1-diphenyl-2-picryl hydrazyl (DPPH), 2,2-azobis(3-ethylbenzothiazoline-6- sulfonate) (ABTS), nitrite and reducing power were also observed in CH. Correlation coefficients (CCs) between analysis parameters were calculated and the highest was identified between TP and ABTS scavenging activity (0.726). The CCs between A400 and TP and A400 and ABTS scavenging activity were 0.644 and 0.661, respectively, suggesting that A400 could be used as a quality indicator for the polyphenol content and antioxidant activity of particular honeys. Future research on polyphenol by flower origin and the identification of compounds for A400 is necessary.

Objectives: The purpose of this study was to obtain a natural antibiotic from Phenol-rich compounds; for the dressing and the treatment of chronic wounds. Methods: The Phenol-rich compound sweet gel was prepared by blending four natural herbal extracts, Acacia catechu (L.F.), Momia (Shilajit), Castanea sativa, and Ephedra sinica stapf, with combination of a sweet gel medium, including honey, maple saps, Phoenix dactylifera L. (date), pomegranate extract and Azadirachta indica gum as a stabilizer. The combinations were screened by using a well-diffusion assay with cloxacillin as a control. Pseudomonas spp. was tested with our novel antimicrobial compound. The zones of inhibition in agar culture were measured for each individual component and for the compound, and the results were compared with those of the control group which had been treated with cloxacillin. Data were expressed as means ${\pm}$ standard deviations. Quantitative analyses were performed using the paired t-test. Results: The antibiotic effect of the Phenol-rich compound sweet gel was statistically shown to be more significant than that of cloxacillin against Pseudomonas aeruginosa (P < 0.05). Conclusion: Our novel approach to fighting the antibiotic resistance of Pseudomonas proved to be successful. The Phenol-rich compound sweet gel was found to be suitable for use as an alternative medicine and bioactive dressing material, for the treatment of patients with various types of wounds, including burns, venous leg ulcers, ulcers of various etiologies, leg ulcers on the feet of diabetic, unhealed graft sampling sites, abscesses, boils, surgical wounds, necrotic process, post-operative and neonatal wound infection, and should be considered as an alternative to the usual methods of cure.
