The onion extractions of MIX treatment (5% $\beta$ cyclodextrin+1% calcium chloride+1% soluble starch mixture solution) using hot water (100${^{\circ}C}$ and 80${^{\circ}C}$) and ultrasonic treatment (25${^{\circ}C}$) incresed L values and decreased a and b values apart from the extraction methods. Extent of the browning reaction as caused by the MIX treatment (0.093) following 100${^{\circ}C}$ water extraction resulted in as low as 31% O.D. level, as compared to the control(0.296). Analysis of the pyruvic acid showed that the control had higher content of pyruric acid than MIX-treated samples. The MIX treatment had lower intensities and higher preferences of browning color and pungency taste compared to the control. The total and coliform microbial counts increased continuously during storage period, while the MIX treatment reduced the number of viable cells. Finally, it was concluded that the MIX treatment was highly effective in suppressing the undesirable browning color and pungent taste after processing, and the microbes increment during storage.

Electronic nose (E-nose) was assessed for grading pungency of powdered red pepper. Complex pretreatments are not required for flavor analysis unlike HPLC or Scoville tests. Mild and pungent taste of powdered red pepper were mixed at various concentrations of 0, 25, 50, 75, and 100%. Those were analyzed using mass spectrometer-based E-nose. Discriminant function analysis (DFA) was conducted on E-nose data. The $R^{2}$ and F-value of dicriminant function first score (DF1) were 0.9946 and 355.65, respectively, when the samples were separated by a relative degree of pungent taste. DF1 value decreased with increasing the amount of powdered red pepper with a pungent taste. It is similar to the increase in the concentration of capsaicin. Increasing the amount of red pepper powder, dicriminant function second score (DF2) values were moved from the negative position into the positive position. The $R^{2}$ and F-value of DF1 were 0.9890, 165.17 and DF2 were 0.9219, 21.64. Also, the results by MS based E-nose agreed to that by HPLC. There is the potential to grade pungent taste of powdered red pepper using the E-nose.

Objective : This research was performed In order to establish the standard of the proper and taste in Korean Medicine. Methods : The change of the proper and taste of Mahwang(麻黃), Gyeji(桂枝), Jagyak(芍藥) and the change of the interpretation of the effect was investigated literally. Results : The hypotheses could be induced as follows. The pungent taste of Mahwang(麻黃) and the sweet taste of Gyeji(桂枝) was inserted by Bonchogyeongso(本草經疏) in Ming Dynasty. In case of Jagyak(芍藥), the proper and taste was changed into sour and cold at Myeonguibyeollok(名醫別錄). It can be proposed that bitter, warm of Mahwang(麻黃), the pungent and warm of Gyeji(桂枝) and the bitter and neutral of Jagyak(芍藥) in Sinnongbonchogyeong(神農本草經) is the adequate proper and taste Conclusions : Therefore it can be hypothesized that the taste and property of Sinnongbonchogyeong(神農本草經) can be established as the standard of the taste and property of Korean Medicine. But in the case of Baekduong(白頭翁), there is the fault of transcribing. So the caution is needed to decide the adequate taste and property.

Ginger (Zingiber officinale Roscoe) is widely used as a common condiment for a variety of foods and beverages. In addition to its extensive utilization as a spice, the fresh or the processed rhizome is a useful crude drug in traditional Chinese medicine. It is considered to possess stomachic, carminative, stimulant, diuretic and antiemetic properties. Chemical studies on the pungent principles of ginger have been carried out by a number of investigators, and 6-gingerol and 6-shogaol as a major pungent substance have been isolated. In this study, the constituents inhibiting a drug metabolizing enzyme CYP3A4 from ginger were investigated. CYP3A4 is responsible for drug metabolism as heme-containing monooxygenases. As a result of experiment, 10-gingerol (lC$_{50}$ 5.75$\mu$M) isolated from EtOAc extract of ginger showed remarkable inhibitory activity compared to 6-gingerol ($IC_{50}$/ 14.56 $\mu$M) and zingerone ($IC_{50}$/ 379.63 $\mu$M). This paper describes the isolation, structure elucidation, and CYP3A4 inhibitory activity of these compounds. The structure of the compounds were identified by instrumental analysis such as LC-mass spectrometer and NMR.R.

Background and Objectives : There are three kinds of formulas for purging the spleen to cure its sthenic syndrome based on the types of preparation formulas : Sabeetang, Sabeehwan, Sabeesan and Sabeeeum. Another formulas called Sahwangtang, Sahwangsan. Sahwangeum is to purge the yellow colour of spleen. There are 8 kinds of Sabeetang, 3 kinds of Sabeehwan, 3 kinds of Sabeesan, 1 kind of Sabeeeum, 4 kinds of Sahwangtang, 7 kinds of Sahwangsan, and 1 kind of Sahwangeum. Combination of herbal medicines, carried out in formulas for purging the spleen, consists of various kinds depending on medical scientists' personal experience in medical treatment without any general principles, which makes it difficult to apply it to clinical use. The objectives of this study lie in theoretical establishment of Sabeetang for curing the sthenic syndrome of spleen through analyzing the component medicines and combination principles of Hyeongok's Sabeetang, and furthermore, maximizing the clinical use of Sabeetang. Methods : This study analyzed the component medicines and combination principles of Hyeongok's Sabeetang based on the theory for properties and tastes of herbal medicines from the ${\ulcorner}$Yellow Emperor's Canon of Internal Medicine${\lrcorner}$ , the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine, and the five elements doctrine. Hyeongok's Sabeetang is an odd prescription, composed of 7 kinds of ingredients : No.1 Rhizoma Coptidis (2don;7.5g), No.2 Fructus Gardeniae (1don;3.75g), No.3 Ramulus Cinnamomi (1don), No.4 Gypsum Fibrosum (1don), No.5 Fructus Aurantii Immaturus (1don), No.6 Cortex Magnoliae Omcinalis (1don), and No.7 Radix Et Rhizoma Rhei (1don) Results : There are three methods for curing the sthenic syndrome of spleen according to the five elements doctrine : purging the spleen, purging the lung and invigorating the liver. First, if you suffer from the sthenic syndrome of the spleen, you need to purge your spleen. There are two available methods, including taste and property purgation according to the theory for properties and tastes of herbal medicines. They each imply the bitter taste and the cool property purge the spleen. In the case of taste purgation, two herbal medicines with bitter taste. Rhizoma Coptidis and Fructus Gardeniae, are combined into the principal and assistant herbal medicine, respectively. For property purgation, three herbal medicines with the cool property, Gypsum Fibrosum, Fructus Aurantii Immaturus and Radix Et Rhizoma Rhei, are combined into adjuvant herbal medicines. Secondly, if you suffer from the sthenic syndrome of the spleen, you need to purge your lung which is child in the mother-child relationship in inter-promotion among the five elements. There are two methods to purge the lung, including taste and property purgation according to the theory for properties and tastes of herbal medicines. They each mean the pungent taste and the warm property purge the lung. Therefore, it is important to use pungent herbal medicines for taste purgation and warm ones for property purgation. Both pungent and warm herb and property invigoration to invigorate the liver with warm property. Therefore, it is important to use pungent herbal medicines for taste invigoration and warm ones for property invigoration. Both pungent and warm herbal medicines, Ramulus Cinnamomi and Cortex Magnoliae Officinalis, were combined to invigorate the liver and purge the lung. In addition, Gypsum Fibrosum are combined as dispatcher herbal medicine, leading all the herbal medicines composing the formula to the spleen. Conclusions : First, to cure the sthenic syndrome of the spleen, the methods of purging the spleen and the lung, and invigorating the liver should be used according to the five elements doctrine. Secondly, herbal medicines appropriate for those treatment methods should be chosen according to the theory for properties and tastes of herbal medicine and thirdly, the combination of those herbal medicines should be carried out according to the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine. As a good example, Hyeongok's Sabeetang is combined according to the above theories. In conclusion, this formula was created by applying to the theory for properties and tastes of herbal medicines.
