본 실험은 벌꿀이 항균활성에 미치는 영향을 규명하기 위해 국내산 벌꿀인 밤꿀, 잡화, 아카시아, 재래종 벌꿀과 외국산 벌꿀인 마누카, 클로버, 캐놀라 벌꿀 그리고 인공벌꿀을 각각 12.5%, 25.0%, 50%의 희석액으로 조제하여 catalase무첨가 또는 첨가한 경우에 있어서 벌꿀의 Staphylococcus aureus에 대한 항균활성을 agar well diffusion assay로 비교한 바 다음과 같은 결과를 얻었다. Catalase 무첨가의 경우 12.5%희석한 벌꿀은 마누카꿀 > 밤꿀이, 25.0%로 희석한 벌꿀은 마누카 꿀 > 밤꿀 > 잡화꿀 > 재래종꿀 > 클로버 꿀 > 아카시아꿀이, 50.0%로 희석한 벌꿀은 마누카꿀 > 밤꿀 > 캐롤라꿀 > 재래종꿀 > 잡화꿀>클로버꿀 > 아카시아꿀 순으로 항균활성이 인정되었다(p>0.01). Catalase 무첨가의 경우 12.5%, 25.0%, 50.0%로 희석한 벌꿀의 생육억제환은 각각 5.85∼6.60mm, 4.26∼8.27 mm, 5.24∼11.49mm 범위였다. Catalase 첨가의 경우 12.5%로 희석한 벌꿀은 마누카꿀에서 만 항균활성을 나타냈다. 25.0%로 희석한 벌꿀은 마누카꿀이 밤꿀보다 항균활성이 더 높게 나타냈다.(p > 0.01). 50.0%로 희석한 벌꿀은 마누카꿀 > 밤꿀>클로버꿀)캐롤라꿀>재래종꿀 순으로 항균활성이 높았으며 마누카꿀, 밤꿀, 클로버꿀, 캐롤라꿀, 재래종꿀 사이에서 유의성이 인정되었다(p > 0.01). Catalase 첨가의 경우 12. 5%, 25.0%, 50.0%로 희석한 벌꿀의 생육억제환은 각각 5.89mm, 5.01∼6.84mm, 3.10 ∼8.28mm범위였다.

To make sure of the usefulness of extract of Rubus coreanus Miquel for producing functional feeding honey, we compared some antioxidative indicators of feeding honey using extract of Rubus coreanus Miquel with acacia honey, SueBee Clover honey(USA), feeding honey on the market. The water content of four honeys were 16.6~26.5%, pH were 3.18~3.70, and titratable acidity ranged 0.018~0.022%. The phenolic compound contents of SueBee Clover honey and feeding honey using extract of Rubus coreanus Miquel were 8.3 mg/100 g and 7.3 mg/100 g, respectively, and were significaltly higher thgheacacia honey and feeding honey on the market. The flavonoid contents per 100 g of honey ranged from 2.3 mg(acacia honey) to 15.0 mg(SueBee Clover honey). DPPH anion scavenging activity of four honeys were not high. 0.5~2.0 g/ml of feeding honey using extract of Rubus coreanus Miquel was 16~36% and showed a concentration-reliant figure. At the concentration of 0.25~0.75 mg/ml, the reducing power of four honeys increased concentration-dependently, and the power of 0.25 mg/ml of feeding honey using extract of Rubus coreanus Miquel was corresponding to thgt of $150{\mu}g$/ml of a vitamin C solution. ABTS radical scavenging activity of feeding honey using extract of Rubus coreanus Miquel was 43.3~68.4%; the highest activity amongst all samples. When plotting the dose-response curve, ABTS radical scavenging activity also increased as their concentration increased from 62.5 mg/ml to 500 mg/ml. The heat treatment reduced the phenolic compound contents of acacia honey and feeding honey using extract of Rubus coreanus DPPH anion scavenging activity of feeding honey on the market and feeding honey using extract of Rubus coreanus Miquel did not changed significaltly after heating for 20 min, and the three honey except SueBee Clover honey maintained the reducing power with the same treatment.

The purpose of this study is concerned with identification of floral type of commercially available honeys and pollen loads. Ikuse's technique was applied to identify the pollen species of honey and pollen loads. Among six kinds of commercially available honeys in Taegu, Korea i.e. Robinia Honey, Brassica Honey, Castanea Honey, Rhododendron Honey, Lespedeza Honey and Multipant Honey, all honeys contained pollens, which were coincident with their trade names given by the apirists, except Lespedeza Honey. The trade name of imported honeys were not given by the plant, from which pollen material and nectar were collected. Among four kinds of these products, pollen was not identified in Clover Honey. A spectrum of honey products added by pollen loads was, of course, wider than simple honey products. The pollen load showed spectrum of pollens including not only those which are specialized for wind pollination, eq. Pinus species and Gramineae, but also contained for insect pollination, eq. rose and leguminous plants.

There is a growing demand for natural sleep aids due to various side effects of long-term administration of pharmacological treatments for insomnia. Honey has been reported to exhibit numerous potential health benefits, and it is hypothesized that honey may favorably affect insomnia treatment. Therefore, this study was performed to investigate the possible hypnotic effect of clover honey (CH) and to determine its in vivo mechanism. The total flavonoid content (TFC) of CH and fractions extracted with ethylacetate (EtOAc) and $H_2O$ was measured. The pentobarbital-induced sleep test using $GABA_A$-benzodiazepine (BZD) agonists and antagonists was conducted to evaluate the potential mechanism of action behind the sedative-hypnotic activity of CH in mice. The results showed that administration of 500 and 1,000 mg/kg of CH significantly (p<0.01) reduced the sleep latency to a level similar to that of diazepam (DZP, 2 mg/kg), and 1,000 mg/kg of CH significantly (p<0.01) prolonged the sleep duration, which was comparable to that of DZP (2 mg/kg). Administration of the EtOAc fraction with a higher TFC significantly reduced the sleep latency at 50 to 200 mg/kg and prolonged the sleep duration at 100 to 200 mg/kg, which were comparable to those after administration of DZP (2 mg/kg). However, co-administration of CH and EtOAc with flumazenil, a specific $GABA_A-BZD$ receptor antagonist, blocked the hypnotic effect. Our findings suggest that the hypnotic activity of CH may be attributed to allosteric modulation of $GABA_A-BZD$ receptors. The TFC of CH is expected to be a key factor that contributes to its hypnotic effect.

Saccharides in Korean honey have been analyzed by traditional wet chemical methods and several chromatographic technics gas, paper, column and thin layer chromatography. A simple, rapid and versatile method for the separation and determination of saccharides via high performance liquid chromatography were used eluting with $H_2O : CH_CN$ at 25:75, at a flow rate of 1.0ml/min. Acasia honey contained 36.8% fructose, 31.4% glucose, 1.7% sucrose and bush clover honey held 34.4% fructose, 32.3% glucose and 30% sucrose. Difference on the regional distribution were not found in the quantity of saccharides (42 species). The quality of inferior honey was assumed to contain much maltose, sugar and glucose than common honey.

The rheological properties of some honey-ginseng powder mixturs, used as pharmaceutical pills, were studied extensively by employing five kinds of honey, acacia, chestnut, buckwheat, green perilla and bush clover. Relation between the viscosity of the sample mixtures and the concentrations of ginseng powder and the temperature effect on the internal change of the structure were studied. The results obtained are as follows: 1) A complete gel formation of honey-ginseng mixtures was observed when about 50 days have passed after the sample preparation. 2) The viscosity of honey-ginseng powder mixtures was related with the concentration of ginseng powder, the temperature and the period of time required in gel formation as shown in the following equation. n=noexp$[{\kappa}_{1}c^{n1}+{\kappa}_{2}(T-273)^{-n2}+{\kappa}_{3} t^{n3}]$
