OBJECTIVETo establish the HPLC fingerprint method and compare the changes of chemical compositions of the processed products from Sinapis alba.

METHODThe procedure of HPLC analysis was performed on a agilent TC-C18 (2) column at 35 degrees C with the acetonitrile -0.1% phosphoric acid in gradient elution as the mobile phase. The detection wavelength was set at 254 nm, and the flow rate was 1.0 mL x min(-1). The similarity evaluation system for chromatographic fingerprint of traditional Chinese medicine (Version 2004 A) was applied to analyze the similarity.

RESULTThe average similarities among the processed products were over 0.96, the standard HPLC fingerprint and five main chromatographic peaks with the isolated compounds was obtained and identified.

CONCLUSIONThe established methods with two solvents are suitable for the HPLC fingerprints determination which elementary elucidate the scientific intensions of breaking the enzyme for glycosides.

PURPOSE: The purpose of this study was to confirm the effects of auricular acupressure therapy on insomnia and nocturia in the elderly. METHODS: This study was a nonequivalent control group pre-post test design. Data collection was conducted from July 1 to August 31, 2013. Subjects were set for totally 36 people with 18 people in the experimental group and 18 people in the control group among the elderly over the age of 60 in silver town, welfare center, and senior citizen center where are located in Seoul area. For the experimental group, auricular acupressure therapy was applied two times during 5 days by fixing it to auricular reaction site with tape using Sinapis alba L. seeds. With SPSS/WIN 19.0 program, the collected data were analyzed. RESULTS: Compared to the control group, the sleeping score and sleeping satisfaction were improved and nocturia frequency was lowered in the experimental group who applied auricular acupressure therapy. CONCLUSION: Auricular acupressure therapy was considered to be likely useful therapeutic method for the effects of relieving nocturia and insomnia in elderly.

OBJECTIVETo study the chemical components of the essential oil of the Semen Sinapis with the different processing methods.

METHODThe essential oils of the crude Semen Sinapis and the roasted Semen Sinapis were extracted by steam distillation. The chemical components were analyzed by means of GC-MS-DS. The relative content of each component was calculated by area normalization.

RESULTThe main chemical components of the essential oil of the crude Semen Sinapis and the roasted Semen Sinapis were similar. The main chemical components were allyl isothiocyanate and 4-isothio-cyanato-1-butene. The chemical components of the essential oil of the crude Semen Sinapis were more than that of the roasted Semen Sinapis.

CONCLUSIONThe effect of different processing methods on the chemical components of the essential oil of Semen Sinapis was significant. Certain chemical components such as isothiocyanato-containing substances, were found in the crude Semen Sinapis.

OBJECTIVETo identify comparatively several commercial Chinese herbal medicines and their counterfeits.

METHODThe micromorphological characters were identified. The shape, surface, section and other characters of the medicinal materials were identified by using anatomical lens and scanning apparatus. Pictures were taken and saved.

RESULTMain micromorphological differences between several Chinese herbal medicine including Lonicera macranthoides, L. similis, Cuminum cyminum, Plantago asiatica, Cuscuta chinensis, Sinapis alba, Salvia miltiorrhiza and their counterfeits were identified.

CONCLUSIONThe reference for the authenticity identification of Chinese herbal medicine and helpful experiences for the research of the same subject were provided.
