Gamiguibi-tang (GGBT) is a traditional herbal medicine generally used to treat anemia, insomnia, anxiety, and nervousness. GGBT is being commercially produced in the form of extract granule and the quality control methods are specified in the Korean Herbal Pharmacopeia (KHP). However, there is no method to simultaneously analyze compound preparations. In this study, a HPLC method was developed and validated for the simultaneous determination of marker compounds in GGBT. And the contents of marker components and biological activities of the commercial GGBT extract granules (GGBT-2 and GGBT-3) were compared with those of the GGBT decoction (GGBT-1). We confirmed the robustness of simultaneous analytical method by monitoring the contents of the commercial GGBT products and carrying out validation. The marker components of GGBT were geniposide ($8.03{\sim}12.70{\mu}g/mL$), paeoniflorin ($2.79{\sim}4.25{\mu}g/mL$) and glycyrrhizic acid ($5.06{\sim}6.30{\mu}g/mL$). DPPH and ABTS radical scavenging activities were 47.34~63.17% and 21.52~33.61% in the GGBT products concentration of $1,000{\mu}g/mL$, respectively. The GGBT products significantly decreased NO, iNOS and COX-2 production in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages in a concentration-dependent manner. The GGBT-2 had higher contents of marker components and biological activities than GGBT-1 and GGBT-3. The research suggest that be used in developing quality control methods for enhancing the quality of herbal medicines.

Socheongryong-tang (SCRT) was one of the major traditional herbal medicines wildly used in the treatment of respiratory disease. SCRT is being commercially produced in the form of mix extracts powder and soft dry extract by different extract methods in the Korean Herbal Pharmacopeia (KHP). In this study, the contents of marker components and biological activities of the SCRT mix extract powder were compared with those of the SCRT decoction. To analyze the marker components of SCRT, nine marker from eight herbal preparations were chosen. And the method using high performance liquid chromatography (HPLC) with diode-array detector method was established for the simultaneous analysis. Method validation was accomplished by linearity, precision test, and recovery test. The contents of nine marker components in this extract was ascertained by ratio. The biological activities were examined the effect of SCRT on anti-oxidation and pro-inflammation mediated by LPS-stimulation. We confirmed that both of SCRT mix extrct powder and decoction have the similar contents on total polyphenol and flavonoid and inhibited the secretion of nitric oxide (NO), $IL-1{\beta}$, IL-6, tumor necrosis factor $(TNF)-{\alpha}$ and the expression of iNOS, COX-2, $IL-1{\beta}$, IL-6, $TNF-{\alpha}$. These results suggest that SCRT mix extract powder and decoction have a significant correlation.

Objectives : The root ofCyanchum wifordii(CW) had been used as herbal medicine, 'Baeksuo', in Korea. However, the root ofCynanchum auriculatum(CA) had also been mis-used as 'Baeksuo' in herbal markets, due to its morphological similarity with CW. This study aimed to compare discriminative features and establish the identification-keys between two herbal medicines using microscopic methods.Methods : Microscopic preparations including fixation, rapid dehydration, paraffin infiltration, paraffin embedding, sectioning, mounting, and staining, were performed and the microscopic features between CW and CA samples were compared.Results : The starch grain of parenchymal cells, the amounts of calcium oxalate crystals, cell sizes, and the shape of phloem were not different between CW and CA samples. However, the clusters of stone cells which were conglomerated at outer cortex were apparently observed in CA sample (4~8 layers of stone cells), but not in CW sample (2~4 layers of stone cells, or not). Xylem of CW consisted of several vessels and fiber bundles which were formed as linear shapes and discontinuous radial lines, while that of CA, in which radial lines was not observed, were shaped as a wedge and scattered near cambium with comparatively few fiber bundles enclosed vessels. Especially, in the xylem of CA, fiber bundles located towards cambium were relatively more developed than those located outward cambium.Conclusions : The identification-keys established in this study would be helpful to discriminate microscopic features between CW and CA.

Chinese medicine is a precious treasure inherited from ancient ancestors. It is accredited for the prosperous growth of the Chinese nations. However, the descriptions of the herbs in the ancient herbal are not in detail and the great numbers of herbs used which grows in wide geographic areas together with various local folk names, new substitutes and new folk medicines had increased, many Chinese herbs are composed of herbs that are labeled with identical names but actually are of different origins and different grades. Similar situation had occurred in China, japan and Korea In Taiwan, misused Chinese crude drugs are also very common in the past. This phenomenon had caused a lot of confusion and had great influence the clinical efficacy of the treatment. In the past, Professor Hong Yen Hsu, Na Chi, Woei Song Kan and Kung Yin Yen had studied the origins of Chinese crude drugs in Taiwan based on the morphological identification and found that the origins of Ma-Tou-Ling, Pu-Kung-Yin, Tu-Chung, Wang-Pu-Liu-Hsing, Pan-lan-Ken, Niu-Chi, Fang-Chi, Huang-Chi, PienHsiu and Sha Wan-Tzi are different from that of the species used in mainland China. In order to assure the quality and clinical efficacy of the crude drugs, besides the traditional morphological methods, we bad recently combined modem chemical and pharma-cological methods to assess drug quality. Drugs that have been evaluated without effects should be abandoned. The species of those commonly misued crude drugs used in compound formula preparations are also identified Based on the pharmacological results, a suitable species is recommended so as to improve the clinical efficacy of those preparations. In this paper, we like to report our recent studies on Niu Chi(Achyranthis Bidentatae Radix, Cyathulae Radix and Strobilanthis Radix). Fang-Chi(Arstolochiae Fangchi Radix, Stephaniae Tetrandrae Radix and Cocculus Radix) and Huang-Chi(Astragali Radix and Hedysari Radix) using comparative pharmacognosy methods.

Objectives: In the past few years, herbal medicines have gained popularity over synthetic drugs because of their natural source and minimal side effects which has led to a tremendous growth of phytopharmaceuticals usage. With the development of nanotechnology, it provides alternative approaches to overcome several limitations using nano-formulations. In spite of considerable quantity of antianemic preparations with different iron forms available, currently additives are used and represented in modern pharmaceutical market. Iron deficiency anemia is a major global public health problem which particularly affects pregnant women, children and elderly persons. The situation is complicated because of disadvantages and drug side effects from existing antianemic medicines. There is a great demand for the development of new antianemic preparations. Green synthesis of iron oxide nanoparticles, possess high potential in this field. Methods: Our study focuses on developing green synthesis of iron oxide nanoparticles (IONPs) of 10-50 nm with spherical shape where different dosages were used -1 mg/kg, 10 mg/kg and 100 mg/kg for exposure in Wistar albino female rats for 28 days. The toxicity was assessed using various parameters such as measurements of the rat body and organ mass, hematology, biochemical evaluation and histopathological examinations. Results: No significant differences were observed in body and organ weights. Hematological indices also indicated no significant differences whereas biochemical factors showed increase in levels of direct bilirubin and globulin of medium as well as high dose and SGPT levels were increased only in high dose. The major organs (heart, kidney and liver) showed histopathological alterations in 10 and 100 mg/kg whereas brain showed only in 100 mg/kg. Conclusion: The toxicity of IONPs was found to be more significant when the concentration was increased; however, low doses can be used for further investigation as an antianemic preparation.

Nineteen Medicaments of Mutual Antagonism currently belong to pharmaceutical incompatibility and some of them cannot be used in a same prescription: if they are used in a prescription, the treatment effect is rather reduced or toxic response may be produced. Therefore. inthisstudy, it was intended to look about how Nineteen Medicaments of Mutual Antagonism were defined through survey of literatures and to review the meaning and clinical potential. According to "Sinnongbonchogyeong," "Medicaments contain the substance that suppress toxins and the toxins may be removed with use of mutual restraint or mutual detoxication substances" and they have been used in terms of this concept. Since Tang and Song era, mutual restraint and mutual inhibition were confused and were difficult to be distinguished. In terms of pharmaceutical incompatibility, the original meaning of mutual restraint was deteriorated in "Sinnongbonchogyeong". That is. mutual restraint has been used as the concept of mutual inhibition or incompatibility. When various literatures were reviewed. it could be found that Nineteen Medicaments of Mutual Antagonism were firstly included in the phrases of songs and then in "seven emotion." It could be supposed that Nineteen Medicaments of Mutual Antagonism was created based on the clinical experiences of the author and the influence of doctors. Such supposition means indicates that the interactions among medicaments could effectively be applied and mutual restraint did not belong to pharmaceutical incompatibility. However. many doctors used mutual restraint and mutual inhibition in clinical practice with no distinguishment since Song era and. especially, it is supposed that. when medicaments were used with mixing. the pharmaceutical incompatibility of "Nineteen Medicaments of Mutual Antagonism" or "Eighteen Incompatible Medicaments" were emphasized and influenced on the efficacy of pharmaceutical preparations or acted as an obstacle in treating diseases. That is. an error was transferred: mutual restraint and mutual inhibition were not distinguished and were discretionally added or deleted through common people or professionals with no specific verification. The pharmaceutical preparations that belong to Nineteen Medicaments of Mutual Antagonism belong to pharmaceutical incompatibility but. when reviewed various literatures and clinical reports. they are not thought to be the ones that can never be used. Therefore. systematic literature review and experimental research should be performed.

Objectives : About 13% of the medicines used by traditional korean medicines(TKM), are called animal medicines and are derived from non-herbal sources such as animals and insects. However, the clinical use of these preparations from animal medicines is often based on tradition and belief, rather than on evidence of toxicity and efficacy. As a result, animal medicines containing toxin have caused serious problems from injecting patients with venom. Here, various venoms frequently used as TKM were reviewed in terms of their instinct toxity and tried to estimate their safety classification. Methods : The estimation of safety classification was based on human equivalent dose(HED)-based MOS (margin of safety) and clinical dose applied for patients. Results and Conclusions : Except that of snake venom due to no clinical dose, they were evaluated as class 3 for bee venom, class 4 for cantharidin, toxin from blister beetle, and class 1 for venom from scolopendrid. In conclusion, animal medicines showed a wide range of safety classification from class 1 to class 4. This wide range is estimated to result from extremely limited applications of each venom for patients because of their strong toxicity. However, it should be cautious for application in clinics since animal medicines can produce anaphylactic reactions particularly after veinous administration even with a tiny amount of venom.

Objective : The study's objective is to assess the components of Dendropanax morbifera (DM) utilizing UPLC-MS/MS and assess their antioxidant properties in order to establish fundamental information for quality control of herbal formulations. Methods : The DM leaves were ground into powder and extracted with water at 80℃. The extract was subsequently concentrated and subjected to freeze-drying for subsequent analysis. The LC-MS/MS analysis was performed using a 1260 series HPLC system and a 3200 QTrap tandem mass system in positive ion mode, with detection conducted at 280 nm. The Folin-Ciocalteu method was employed to measure the phenolic content, while a colorimetric method using aluminum chloride was used to determine the flavonoid content, with gallic acid and quercetin as standards, respectively. The evaluation of antioxidant activity was conducted through the measurement of DPPH radical scavenging activity, by adding the DPPH solution to the extract and recording the absorbance at 517 nm. Results : The UPLC-MS/MS analysis identified five polyphenolic compounds in the DM extract, specifically syringin, 6-hydroxyluteolin 7-O-laminaribioside, shaftoside, rutin, and kaempferol-3-O-rutinoside. The extract was found to contain a total phenolic content of 83.106 ± 0.21 mg GAE/g and a total flavonoid content of 87.963 ± 1.014 mg QE/g. The DM extract demonstrated substantial antioxidant properties, resulting in a reduction of DPPH radicals that was evident at concentrations as low as 40 ㎍/㎖. Conclusions : The study determined important polyphenolic compounds in DM and established its considerable antioxidant efficacy. These findings provide evidence for the efficacy of DM in disease prevention related to oxidative stress and establish a foundation for ensuring quality control in herbal preparations.

Geniposide is an active product extracted from the gardenia fruit, and is one of the most widely used herbal preparations for liver disorders. This study examined the cytoprotective properties of geniposide and its metabolite, genipin, against hepatic ischemia/reperfusion (I/R) injury. C57BL/6 mice were subjected to 60 min of ischemia followed by 6 h of reperfusion. Geniposide (100 mg/kg) and genipin (50 mg/kg) were administered orally 30 min before ischemia. In the I/R mice, the levels of serum alanine aminotransferase and hepatic lipid peroxidation were elevated, whereas hepatic glutathione/glutathione disulfide ratio was decreased. These changes were attenuated by geniposide and genipin administration. On the other hand, increased hepatic heme oxygenase-1 protein expression was potentiated by geniposide and genipin administration. The increased levels of tBid, cytochrome c protein expression and caspase-3 activity were attenuated by geniposide and genipin. Increased apoptotic cells in the I/R mice were also significantly reduced by geniposide and genipin treatment. Our results suggest that geniposide and genipin offer significant hepatoprotection against I/R injury by reducing oxidative stress and apoptosis.
