  • Guibi-tang, a traditional herbal medicine, is used for anti-oxidant, anti-osteoporosis, hemostasis and gastroprotection. To develop an analysis method of simultaneous determination of six compounds, swertisin, decursinol, glycyrrhizin, 6-gingerol, costunolide and decursin in Guibi-tang, a high performance liquid chromatography was used with diode array detector. Six bioactive components were separated on a SHISEIDO $C_{18}$ column ($5\;{\mu}m$, 4.6 mm I.D.${\times}$250 mm) with column temperature $30^{\circ}C$. The gradient elution was composed of water with 0.1% trifluoroacetic acid (TFA) and acetonitrile. UV wavelength was set at 230 nm, 254 nm and 330 nm, respectively. Calibration curve showed good linear regression ($R^2$ > 0.9999). The limits of detection (LOD) and the limits of quantification (LOQ) ranged in 0.03 - 0.23 ${\mu}g/ml$ and 0.08 - $0.70\;{\mu}g/ml$, respectively. The RSD values of intra- and inter-day test were in the range of 0.03 ~ 0.96% and 0.01 ~ 1.46%, respectively. The evaluated results of accuracy test were varied from 92.28% ~ 105.14% with RSD < 1.60%. In conclusion, this developed simultaneous determination method was accuracy and sensitive to the quality evaluation of Guibi-tang.

  • Sipjundaebo-tang was a well-known restorative traditional herbal prescription that used to treat anemia, anorexia, fatigue and inflammation. In this study, we examined the bioconversion of compounds in the Sipjundaebo-tang (SJ) and fermented Sipjundaebo-tang with Lactobacillus fermentum KFRI 164 (FSJ) using established HPLC-DAD method. The chromatogram of FSJ has shown that the contents of six bioactive compounds 5-HMF, paeoniflorin, ferulic acid, cinnam aldehyde, decursin, glycyrrhizin in SJ has decreased. And the contents of unknown compounds (1), (2), (3), (4) and (5) in FSJ were higher than each contents of SJ. The antioxidant activities of SJ and FSJ were conducted by DPPH free radical and Hydrogen peroxide ($H_2O_2$) scavenging assay. Electron donating activity (EDA, %) value of FSJ has shown higher than 21.9% and 14.5% at a concentration of 0.5 mg/ml for DPPH radical scavenging activity and $H_2O_2$ scavenging activity, respectively. Also, the neuroprotective activities of SJ and FSJ against glutamate-induced oxidative stress in a mouse hippocampal cell line (HT22) were evaluated by MTT assay. As a result, FSJ has shown higher neuroprotective activity than 56.5% comparing with SJ. In conclusion, the fermented SJ using microorganism could convert compounds in SJ and enhance antioxidant activity and neuroprotective activity.

  • Objectives Danggwisoo-san and Jakyakgamcho-tang are frequently prescribed for traffic accident patients in Korea. The aim of this study was to examine index compound analysis, antioxidant activity and amount of starch measurement by extraction method. Methods Danggwisoo-san and Jakyakgamcho-tang were extracted with water and 70% ethanol. Antioxidant activity was measured by 2,2-Diphenyl-1-picrylhydrazyl, 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and ferric reducing antioxidant power according to the standard protocol. The contents of the indicator components nodakenin, paeoniflorin, and glycyrrhizin were measured by high-performance liquid chromatography, respectively. All starches were hydrolyzed and then total D-glucose was measured and compared. Results Antioxidant activity was excellent in 70% ethanol in all assays. The index component was jagged because its solubility was different depending on the extraction solvent. Starch content was significantly lower in 70% alcohol extract than water extract. Conclusions The results of this study showed that physiological activities and components are different according to extraction conditions. Each herbal medicine has a suitable extraction solvent. Also, the difference in starch content is an object to be considered as it may affect digestion and absorption.

  • Objectives: This study was performed to compare the differences between decoctions extracted by different extraction method and extraction time. Methods: Decoctions were prepared with pressurized or non-pressurized extraction for 60, 120 and 180min. The yield of extract, total soluble solid content, hydrogen ion concentration(pH) and the content of reference compound in Sipjeondaebo-tang (Siquandabu-tang) were investigated. Results: While yields and the total soluble solid of decoction were higher in pressurized method proportional to extraction time, pH values were lower in pressurized method and showed decreasing values with increasing extraction time. Albilflorin, ferulic acid, nodakenin, coumarin, cinnamaldehyde and glycyrrhizin were contained in decoctions by pressurized extraction method more than non-pressurized method whereas the content of coumarin was higher in decoctions by non-pressurized extraction method. In addition, coumarin was extracted increasingly with extraction time in decoctions by pressurized method, however, nine compounds except cinnamaldehyde showed the tendency of increasing proportional to extraction time. Conclusions: The results show that extraction methods including pressurized or non-pressurized extraction, and extraction time could affect the physicochemical characteristic or composition of Sipjeondaebo-tang(Siquandabu-tang) decoction.

  • The developmental toxicity of water extract of licorice (Glycyrrhiza glabra) was evaluated in rats. Licorice extract (500, 1,000 or 2,000 mg/kg) was dissolved in drinking water and orally administered to male rats from 9 weeks before mating to the day of copulation, and to females from 2 weeks before mating to gestational day 19. On gestational day 20, the animals were sacrificed for Cesarian section, and maternal and fetal abnormalities were examined. Licorice extract neither induce clinical signs, nor affect the body weight gain, feed and water intake, estrous cycle, copulation and fertility rates, blood $17\beta-estradiol$ level and organ weights of dams. Also, the implantation and development including body weights, absorption and death of embryos and fetuses were not influenced by in utero exposure to licorice. In addition, there were no increases in external, visceral and skeletal abnormalities of fetuses. Taken together, it is suggested that no observed adverse effect level of licorice extract is higher than 2,000 mg/kg, and that long-term in utero exposure to licorice might not cause developmental toxicities of embryos and fetuses.
