Objectives : This study was performed to compare the differences between decoctions extracted by different extraction method and extraction time. Methods : Decoctions were prepared with pressed or non-pressed extraction conditions for 60, 120 and 180min. The yields of extracts, sugar contents, hydrogen ion concentrations(pH), the contents of reference compounds in Yukmijihwang-tang(Liuweidihuang-tang) were investigated. Results : The yields and the dissolved solid content containing sugar content of decoctions were more in pressed extraction method than unpressed extraction method, and they tended to be increased as extraction time increased. The pH values of decoctions methods did not show significant differences between pressed and unpressed extraction methods or extraction times. Most of reference compounds showed higher contents in pressed extraction method than unpressed extraction method and their contents were augmented according to increase of extraction time. The content of paeonol was decreased when extracted in more than 120min with pressed extraction method and tended to be decreased as extraction time increased in unpressed extraction method. Conclusions : The pressed extraction with long extraction time could be useful for decoction of Yukmijihwang-tang(Liuweidihuang-tang). However, another ingredients possible to decrease in such condition need to be considered to determine suitable extraction condition.

Objectives : In other to determine the optimal extraction conditions, the various Bojungikgi-tang (BJIGT) decoctions prepared by different pressure levels and different extraction times were compared and evaluated in terms of the extract yield and the total soluble solid content. Methods : Decoctions were prepared by the pressure levels of 0 (non-pressurized) and 1 $kgf/cm^2$ (pressurized) for 60, 120 and 180 min. The extract yield and the total soluble solids content of decoctions were measured, and the amounts of the reference compounds in decoctions were investigated by the analysis using high performance liquid chromatography. Results : The extract yield and the total soluble solid content were higher in decoctions extracted by the pressurized method than those from decoction with non-pressurized method. The patterns of yield and contents showed a proportional increase to the extraction time. In analysis of the linear regression for four reference compounds such as liquiritin, nodakenin, hesperidin, and glycyrrhizin, the good linearity with the correlation coefficient more than 0.9999 was observed. The highest contents for four reference compounds were observed at 180 min of both the pressurized method and the non-pressurized method. Conclusions : This study suggests that the pressure in extraction method and the extraction time affect the compositional constituents in BJIGT decoctions. The extraction time of 180 min could be chosen in both pressurized and non-pressurized method as optimal extraction condition.

With tablets and powder, decoction has been a widely-used method of medicine formula. However, for these formulas have unique bitter tastes and flavors of herbal component materials as it is, the compliance of herbal medicine is severly decreased especially for female and younger patients. Consequently, expected treatment effects can't be acquired completely. If loathsome tastes and flavors of decoction were effectively reduced while pharmacological activity were kept intact, the compliance could be promoted Chong-Myung-Tang has been widely prescribed for student patients with memory This study shows that Chong-Myung-Tang+chocolate have no difference from Chong-Myung-Tang in terms of pharmacological activity. Sensory difference with net chocolate was also surved. In order to observe the difference of Chong-Myung-Tang+chocolate and Chong-Myung-Tang, memory impairment was induced by intraventricular injection of $A{\beta}_{25-35}$ peptides on mice and Chong-Myung-Tang and Chong-Myung-Tang+chocolate were administered orally for 14 days. In water maze task, improvement of learning ability during acquisition period and significant increase of memory score during retention period resulted from the treatment of Chong-Myung-Tang and Chong-Myung-Tang+chocolate with respect to the $A{\beta}-injected$ control animals. Furthermore, the $A{\beta}_{25-35}$ toxicity on the hippocampus was assessed with immunohistochemistry (Bax, TUNEL), and differences in antioxidant activity was observed through TBARS and DPPH test. We employed sensory tests using chocolate flavor, herb flavor, and bitter taste & hardness as standards to show sensory differences with net chocolate. In this study, it is demonstrated that Chong-Myung-Tang+chocolate do not disturb the pharmacological activity of Chong-Myung-Tang, and have no sensory difference with net chocolate. Chong-Myung-Tang+chocolate can be used to enhance the compliance remarkably and thought of as an effective, functional formula to maximize expected treatment.

The result of the study about the cultivation, the constituents, the sweetenity, and the development of preparations of Stevia and Hydrangea are as follows: 1. Hydrangea thrived at $200{\sim}1,400m$ above the sea-level, and the good ones were brought up at $600{\sim}1,200m$. 2. The good ones which belonged to the genera of Hydrangea were produced in the damp, dark and cold place. 3. The growth and cultivated yield of Stevia was not significantly influenced by the acidity of the soil. 4. The best season was May and June for propagation of Stevia by cutting method. 5. The growth rate of Stevia and Hydrangea was really good in the sandy fertile soil, but in the mucotic soil it was not suitable. 6. The extraction and separation of phyllodulcin by solvent had many difficulties, because it was very soluble in water, ethanol, ether, petroleum ether, acetone and benzene, etc. 7. The solubility of stevioside on the solvent was as follows: It was very soluble in water and methanol, slightly soluble in ethanol and acetone, and insoluble in ether, petroleum ether and chloroform. 8. The alkaloid reaction by Mayer reagent in Hydrangea extract was positive. 9. The ashification rate of Stevia was 8.66% to 8.72% and that of Hydrangea 17.02% to 17.04%. 10. The tannin of Stevia leaf was 7.80% to 7.88% and its of Hydrangea decreased 9.46% to 6.08% by fermentation. 11. The percent rates in minimum concentration-occurring sweetness in sugar, glycyrrhiza methanol extract, Hydrangea water extract, Stevia leaf water extract, decoction of Stevia's leaf, decoction of Stevia's stem were as follows: 1.2, 0.1, 0.1, 0.2, 0.4, 0.01, 0.1, 0.6. and sweetenity ratios of those were 1, 12, 12, 6, 3, 64, 12, 2, 12. It was very meaningful to develop preparations of stevia as stevioside, micronized powder, water extract, methanol extract and compound teas and in Hydrangea, water extract, methanol extract, single tea, and compound teas were less meaningful. 13. The genera of Hydrangea which is natural species in Korea was positive in phyllodulcin-identification test, but it was not available to make the sweet tea because of having a little content.

The purpose of this study was to review the research on treating depression in Traditional Chinese Medicine(TCM) over the last 5 years to set the foundation for further studies. We searched for and analyzed articles about depression in CNKI(China National Knowledge Infrastructure) from January 2010 to December 2014. The results were as follows : The most frequently used diagnostic criteria was CCMD-3(The Chinese Classification of Mental Disorders-3), and the most used evaluation criteria was HAMD(Hamilton Depression Rating Scale). Prescription of decoction of medical herbs was most frequently used as a therapeutic method. Acupuncture, traditional Chinese psychotherapy, and music therapy were also used for some studies. The most frequent TCM Syndrome Differentiation Type was stagnation of liver-QI. For decoction of Chinese herbs, Soyo-san(Xiaoyao-san) and Sihosogan-san(Chaihushugan-san) were most often prescribed, and Bupleuri Radix, Paeoniae Radix Alba, Curcumae Radix, Poria cocos wolf, Angelicae Gigantis Radix, Atractylodis Rhizoma Alba were mainly used for medical herbs. BaekHoi(GV20) and Yindang(Ex-HN3) were often used as acupuncture sites. Post-Stroke Depression was the most common case of intercurrent or secondary depression. According to the Jadad Quality Assessment Scale, the quality of the reports was not high as most of the reports had a score of 3 or below. Most systematic reviews on depression were conducted by Chinese researchers. The problem with Clinical research on depression, according to those reviews, was that there were no standardized criteria for the diagnosis and treatment and the trials were usually not randomized nor controlled. We found out there are various clinical methods for treating depression in TCM, and hope that this research could provide the preliminary data for designing and conducting clinical trials for depression.

본 연구에서는 새로운 전처리를 통한 홍삼을 제조하여 홍삼의 향취미의 변화를 살펴보았으며 이로써 맛과 향이 개선 된 홍삼제품을 개발하고자 하였다. Acid(ascorbic acid, citric acid) 감압침투 방법으로 산처리 홍삼을 제조하였으며, 반 건조 산처리 홍삼과 반건조 홍삼의 색, 유리당, ginsenoside 함량, 관능검사를 실시하였다. 홍삼분말 색은 산을 처리하면 밝기 (L)와 황색도 (b)도는 감소하며, 적색도 (a)는 증가하는 것으로 나타났다. Fructose, glucose는 산을 처리하지 않은 홍삼이 가장 높았으나 sucrose, maltose는 citric acid 처리한 홍삼이 높게 나타나는 것을 알 수 있었다. Ginsenoside 함량은 산을 처리한 홍삼에서 $Rg_2+Rh_1$, $Rg_3$의 함량이 증가 되는 것을 알 수 있었다. 산을 처리한 반건조 홍삼과 일반 반건조 홍삼 관능검사에서는 색과 단맛에서만 유의적 차이가 나타났다. 그러나 건조 홍삼 추출물을 관능 검사한 결과 쓴맛과 떫은맛, 신맛, 향취, 색의 강도에서는 유의적 차이가 나타났다. 특히 산 처리한 홍삼 추출물은 쓴맛과 떫은맛이 감소되어 산으로 전 처리한 홍삼은 인삼에 대한 거부감을 줄일 수 있는 제품으로 사용 가능성을 보여 주었다.

A high performance liquid chromatographic (HPLC) method for the simultaneous determination of marker constituents, baicalin and glycyrrhizin was established for the quality control of traditional herbal medicinal preparation, Eul-Ja-Tang (EJT). Separation and quantification were successfully achieved with a Waters XTerra RP18 column ($5{\mu}m$, 4.6 mm I.D. ${\times}$ 150 mm) by gradient elution of a mixture of acetonitrile and water containing 0.03% phosphoric acid (pH 2.03) at a flow rate of 1.0 mL/min. The diode-array UV/VIS detector (DAD) was used for the detection and the wavelength for quantification was set at 250 nm. The presence of baicalin and glycyrrhizin in this decoction was ascertained by retention time, spiking with each authentic standard and UV spectrum. Both baicalin and glycyrrhizin showed good linearity ($r^2$ > 0.999) in a relatively wide concentration ranges. The R.S.D. for intra-day and inter-day precision was less than 5% and the limits of detection (LOD) were about 30 ng. The mean recovery of each compound was 99.5 - 101.2% with R.S.D. values less than 4.0%. This method was successfully applied to the determination of contents of baicalin and glycyrrhizin in three commercial products of EJT, which resulted in the difference in the contents of these compounds. These results suggest that the developed HPLC method is simple, effective and could be readily utilized as a quality control method for commercial EJT products.
