Objectives : In the present study, the contents of cinnamic acid and cinnamaldehyde in three different parts of Cinnamomi Ramulus (CR) (the whole body, the bark part, and the wood part) was evaluated using UPLC (ultra performance liquid chromatography) in order to investigate a suitable cutting method. Methods : Analysis was performed on SMART LC with UV detector. Reference compounds were separated on Inertsil ODS-4 column ($2.1mm{\times}50mm$, $3{\mu}m$, GL Science, Japan) using isolation elution with water and acetonitrile each containing acetic acid at a flow rate of $500{\mu}L/min$. Additionally, samples of CR were purchased from pharmacy of medicinal herb. Results : The correlation coefficients of the cinnamic acid and cinnamaldehyde levels showed good linearity ($r^2{\geq}0.9999$) over the linear ranges. Furthermore, the bark part exhibited higher concentration levels of reference compounds than the wood part in all samples. In addition the bark exfoliation rates in oblique and perpendicular-long cut samples of CR were lower than the perpendicular-short cut samples. Conclusions : These results suggested that the optimal cutting method would be able to reduce the bark exfoliation. Therefore, the oblique or perpendicular-long cutting method is considered to be a better cutting type than the perpendicular-short cutting method.

This research was planned and executed to evaluate how the composition of Yack-sun (oriental diet therapy) tea can effect the health conditions of people who are suffering from diet-related diseases such as being overweight, obese and hyperlipidemic, by taking Yack-sun tea in a form of nutritional supplement with daily meals. We produced Kangjieum with Lycense Mill., Polygonum multflorum Thunb, Cassia tora L., Crataegus pinnatifida Bge and Salvia miltiorrhiza Bge. We evaluated the effects of this tea on serum lipids, on homocysteine concentration, and on active oxygen contents, oxidative stress by clinical practices. We have determined that this tea has a significant effect on decreasing body fat content, decreasing total cholesterol, decreasing LDL-cholesterol, and decreses triglyceride and homocysteine concentrations. In addition, blood active oxygen content and oxidative stress were significantly decreased. We think that scientific and objective evaluation was performed on the components of Kangjieum prescription. We concluded that we could apply the components, not only in a form of tea, but also in other forms of various foods. The information we received from this conclusion will be basic information on how we can apply oriental medicinal resources into other food and will be a steppingstone for medicinal herbs to place a foot in the field of functional food research, which already draws sizable attention world-wide.

Attempts were made to determine the effects of 5-Korean wild vegetabel consumptions on blood glucose leveles and orgen-energy metabolisms in streptozotocin-induced diabetic rats. The 5-Korean wild vegetables were : Cassia tora L.(C.t), Lycium chinese Mill(L.c), Trichosanthes kirilowii Max(T.k), Polygonatum odoratum var. Pluriflorum Ohwi(P.o) and Arctium lappa L(A.l). Sixty male Spargue-Dawley rats(160-220g) were induced diabetes mellitus by streptozotocin injection into the tail vein and were devided into 6 groups : a diabetic control and 5-experimental groups. All groups of the rats were fed on a AIN-76 diet, and the 5-experimental groups were fed with each wild vegetable (10%) for four weeks. An increased tendency in body weight of all the groups was observed and the tendency was more significant in L.c, T.k. and P.o. groups. The organ weight of liver and kidney were higher in L.c. and A.l. groups and lower in T.k. group which has shown the improvement from diabetes. Plasma glucose levels were markedly decreased from the 1st week in C.t, T.k. and P.o. groups and the tendency has lasted throughout the four weeks experimental period. The consumption of P.o. has decreased plasma cholesterol level while any significant difference was not seen in plasma protein levels from all the experimental groups. The level of plasma triglyceride was decreased in P.o. group and the levels of plasma free fatty acids were also significantly lower in P.o. and T.k. groups. The liver protein levels were significantly higher in P.o. and T.k. groups and these two groups also showed the negative or relatively small amount of urinary glucose excretion. The experimental group of T.k. has revealed the decreased level of muscles protein and the increased level of muscle glycogen. The 5-Korean wild vegetables contained dietary fiber and 9-analyzed minerals comparable to the ordinary use vegetables.

The Contents of proximate compositions, vitamin C and minerals(Ca, P, Fe and Zn) of five Korean wild vegetables were analyzed. Twenty four cooking recipes with three of the vegetables were developed and their taste characteristics were evaluated by 12-trained panels. The five Korean wild vegetables are Cassia tora(C.t.), Lycium chinese Mill(L.c.), Trichosanthes quadricirra MIQ(T.q.), Polygonatum japonicum MORR et DECAIS(P.j.) and Articum lappa L.(A.l.). They have been known as the efficacious plants agaginst diabetes mellitus. In our previous work, their hypoglycemic effects have been studied through streptozotocin-induced diabetic rats and fed on the wild vegetables. Contents of moisture were 14~86% in the samples and L.c. showed relatively higher content of crude protein(16.4%). High level of crude fat was seen in C.t.(9.4%). Contents of vitamin C were also relatively high in the wild vegetables(14.2~42.0 mg%). Analysis of minerals revealed the high level of Ca in L.c. leaves, P in A.l. and Fe in C.t. and L.c. leaves. All of the samples contained Zn in 5.0~14.6 mg%. Twelvetrained taste panels indicated that the 24-preparations of L.c. leaves, fruites and P.j. were well accepted in taste, color and odor. Although L.c. fruit gruel, L.c. cream soup and P.j. saute were evalulated as less acceptable, their sensory scores were in 3.6~5.4 which were not undesirable. The newly developed cooking recipes of L.c. fruits and leaves showed better scores in color and texture, P.j. in texture and odor.

Sokmyeungtang was the representative prescription for Apoplexy under the rule of Tang and Song dynasty of which the cultures were thriving in the history of China. However, the clinical use of Sokmyeungtang has been gradually reduced since Geumwon dynasty of China because it was misunderstood that the dryness heat drugs of pungent in flavor and warm in property such as Ephedra, Pubescent Angelica Root, Chinese Cassia Tree-Bark, Divaricate Saposhnikovia Root, Prepared Aconite Root, Fresh Ginger, and Wildginger Herb included in the presciption for Apoplexy supplemented heat as damaging Yin flood. In fact, the drugs pungent in flavor and warm in property activate exterior and interior circulation, circulate channels and collaterals, promote blood circulation, and remove blood stasis with the side effect of relieving exterior syndrome with drugs warming channels. When treating Apoplexy with Sokmyeungtang, the cold drugs such as Gypsum, Baikai Skullcap Root, and Pueraria Root are prescribed to suppress fire of pungent dryness and to control excessive heat of people with Apoplexy as reducing the effects of hot drugs causing impairment of Yin. For treatment of Apoplexy, the above drugs accelerate blood and Qi circulation in channels and collaterals and then in necrotic tissue of human body as removing blood stasis. Consequently, these drugs improve disorders of capillary tube circulation. If Sokmyeungtang, an old prescription, is properly understood, it will be substantially helpful to all kinds of treatments in clinical cases

Five essential oils and 15 herbal extracts were evaluated to control Bursaphelenchus xylophillus in laboratory. The essential oils from clove plant (Syzygium aromaticum), mustard (Brassica integrefolia), thyme (Thymus vulgaris), and Pelargonium inquinans were found to be highly promising and gave excellent control of the nematodes at all the time of exposure. Among them, the least one gave 91.3% mean mortality rate at 24 hours of exposure time, which is highly significant from the control. While in the second study, most of the methanol (Desmodium caudatum, Paulownia coreana, Auckulandia lappa, Sophota flavescens, Aloe sp., Rheum palmatum, Zingiber officinale, Magnolia officinalis, and Eugenia caryophyllata), hexane (Torreya nucifera, Pharbitis nil, Prunus mume, Melia azedarach, and Xanthium strumarium), and hot water (Cinnamomum cassia) herbal extracts killed the nematodes, but in varying degrees compared to the control. Only one extract was found to be promising viz Magnolia officinalis which found to be statistically different from the control and gave mean mortality of 72, 82.3, and 85.3 % for 24, 48, and 72 hours exposure, respectively. Further screening was conducted for M. officinalis with concentrations of 1,000, 100, and 10 ppm against the same species of nematode with the same time of exposure. However, it gave an excellent result for 1,000 ppm for all time of exposure, whereas for the 100 and 10 ppm it gave mean mortality of 39.5 and 25.8% for the time 72hrs, respectively that were statistically different from the control.

The methanol extracts of 25 leguminous seeds in vitro was evaluated for inhibitory activities against the small intestinal $\alpha$-glucosidase of Sprague Dawley male rats. The responses varied both with leguminous seed types and concentrations used. At the concentration of 0.5 mg/ml, the methanol extracts of Cassia obtusifolia, Glycine max var. yagkong, Glycine max var. hooktae, Glycine max var. geumdu, Glycine max var. mejukong, Glycine soja, Phaseolus multiflorus, Pisum sativum, and Vigna sinensis inhibited over 50% of the enzyme activity. The extracts of G. max var. yagkong and V. sinensis showed relatively strong inhibitory activities against $\alpha$-glucosidase at the concentration of 0.1 mg/ml. The activity of each solvent fraction from G. max var. yagkong and V. sinensis was determined, and potent activities were detected from chloroform and butanol fractions, respectively. $IC_{50}$ values of G. max var. yagkong and V. sinensis were 0.06 and 0.19 mg/ml, respectively. As a naturally occurring therapeutic agents, leguminous seeds examined could be useful for developing new types of antidiabetic agents.
