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.

A high performance liquid chromatographic (HPLC) method for the simultaneous determination of marker constituents, paeoniflorin and glycyrrhizin was established for the quality control of traditional herbal medicinal preparation, Sayuk-san (SYS). Separation and quantification were successfully achieved with a Waters XTerra RP18 column ($5{\mu}m$, $4.6mm\;I.D.{\times}150mm$) 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 230 nm. The presence of paeoniflorin and glycyrrhizin in this decoction was ascertained by retention time, spiking with each authentic standard and UV spectrum. All two compounds showed good linearity ($r^2$>0.996) in a relatively wide concentration ranges. The R.S.D. for intra-day and inter-day precision was less than 7.3% and the limits of detection (LOD) were less than 55.7 ng. The mean recovery of each compound was $102.3{\sim}111.1%$ with R.S.D. values less than 4.6%. This method was successfully applied to the determination of contents of paeoniflorin and glycyrrhizin in three commercial products of SYS. These results suggest that the developed HPLC method is simple, effective and could be readily utilized as a quality control method for commercial SYS products.

In the field of oriental medicine, many researchers head for the aim of standardization. To achieve this aim, oriental medical researchers have been carried out experimental research, statistical research, clinical research, philological research, etc., and, have published their results to journals. But, the declaration of Roman name of herbal formula is not united each other, on several article. So, we should prepare database to search in domestic and overseas, and should consider compatibility of internationally used search system. Also, it is need to use appropriate roman letters in oriental medical terms for people can use easily. We inquired the type of roman letters in the name of formula of article that were carried oriental medical journal, to find out appropriate roman letters and to the demands of the times. There were many cases that Korean name of formula is not correspond to the declaration of Korea roman letters. Also, the declaration of roman letters for preparation like as tang(湯), san(散), hwan(丸) etc. are not standardized. To facilitate making database and forming search system, now we suggest that we can standardize the declaration of Korea roman letters by using of Hangul(한글) word processor's toolbar which has transformation of roman letters.

Objects : In this study, I aimed to determine the size and administration Method of pills preparation in Treatise on Cold Damage Diseases. Methods : I investigated the Treatise on Cold Damage Diseases, Newly Revised Materia Medica, Variorum of the Classic of Materia Medica, The Korean Herbal Pharmacopoeia, and recent studies. Results : There were four kinds of pills preparation. Each size of pill preparation was equal to the Odongja, Tanwhan, Yolk, and quarter of daily dosage of Decoction. One pill of Tanwhan was equivalent to 16 pills of Odongja, and one Yolk was equal to 40 pills of Odongja. The Diameter of Odongja was 6.5 mm, Tanwhan was 16.37897 mm, and Yolk was 22.11484 mm. Jeodangwhan was equal to one quarter daily dosage of Jeodangtang. Maximum size to swallow with water was Odongja and daily dosage, which was 16 pills, includes one square-inch-spoon of powder preparation. When we made the pill preparation, it is difficult to make 16 pills using one square-inch-spoon of powder. Therefore, Zhang Zhongjing made one dosage started from 10 pills to 20 pills to find out optimum dose. Due to the difficulty of making precise size of pills and considerable amount of daily dosage, there was no smaller size than Odongja. When the size of Pill preparation was larger than Odongja, it was ground or boiled slightly to make suspensions. Conclusions : These results suggest that the sizes of Pill preparation in the Treatise on Cold Damage Diseases were true compared with reality.

Background: Rehmanniae radix preparata (RRP) has been used as a traditional medicine and is one of the most important oriental herbal medicines. However, the physical characteristics of RRP are not suitable for use in industry. The present study was under-taken to determined the preparation method of RRP powder and the physicochemical characteristics of RRP powder by milling under different pre-freezing temperatures. Methods and Results: Moisture content, powder yield, particle size, bulk density, compressive stress, extraction yield, and 5-HMF content of PRR powders by milling with pre-freezing temperatures (-20, -40, -60, and $-80^{\circ}C$) were analyzed, and correlation among these factors was determined. Powder yield increased and particle size decreased in a pre-freezing temperature-dependent manner from -20 to $-60^{\circ}C$. The Hausner ratio increased from 1.186 to 1.225 with decreasing temperature from -20 to $-80^{\circ}C$, whereas compressive stress showed the opposite trend. Extraction yield and 5-HMF content were not significantly different between RRP powder. Significant correlations were observed among pre-freezing temperature and physical characteristics (e.g., yield, particle size, Hausner ratio, and compressive stress). Conclusions: These results suggest that the pre-freezing temperature is an important factor affecting the physical characteristics of PRR powder and applicable to the industrial production of RRP powder.
