Objectives : The purpose of this study was to assume the origin and daily dose of Allii Chinensis Bulbus in Treatise on Cold Damage Diseases and Prescriptions of the Gold Chamber. Methods : I assumed the origin with Book of Materica Medica such as Illustration and Classic of Materia Medica(本草圖經), Illustration and Consideration of Plant's Name and Reality(植物名實圖考), The Korean Herbal Pharmacopoeia Forth Edition, Annotation of Hangeul Treatise of Cold Damages Diseases, and daily dose based on general principle applied on dose of Treatise on Cold Damage Diseases. Results : In Treatise on Cold Damage Diseases and Prescriptions of the Gold Chamber, the original species of Allii Chinensis Bulbus was Allium chinense G. Don. It was to be measured with weight. It was too big to write on size due to it's 10~30mm length and 3~12mm in diameter. And due to irregular size, it can't be written on number, too. Daily dose of Allii Chinensis Bulbus in Whaeyeok-san(回逆散), Gwalluhaebaekbanha-tang(栝樓薤白半夏湯) was 3 Ryang(兩), which was the most common case in Treatise on Cold Damage Diseases. And that in Gwalluhaebaekgyeji-tang(栝樓薤白桂枝湯), Gwalluhaebaekbaekju-tang(栝樓薤白白酒湯) is 8 Ryang(兩), which was the largest dose as dried herb in Treatise on Cold Damage Diseases Conclusions : The original species of Allii Chinensis Bulbus was Allium chinense G. Don. The daily dose of Allii Chinensis Bulbus was 3 Ryang(兩)(19.5g) in Whaeyeok-san and Gwalluhaebaekbanha-tang, and was 8 Ryang(兩)(52g) in Gwalluhaebaekgyeji-tang and Gwalluhaebaekbaekju-tang.

Objectives : The purpose of this sutdy was finding out the origin and daily dose of Allii Fistulosi Bulbus in Treatise on Cold Damage Diseases. Methods : In order to estimate the origin and daily dose of Allii Fistulosi Bulbus, I researched the Treatise on Cold Damage Diseases, Synopsis of Prescription of the Golden Chamber, Classified Emergency Materia Medica, Compendium of Materia Medica, and Huangdi's Internal Classic. Results : According to some important herbal textbooks, Allii Fistulosi Bulbus had no seed, was reproduced by rhizome, and its leaves were soft. Chongbaek in Treatise on Cold Damage Diseases did not include word 'raw'. The unit of the dose of it was the number of article. So Allii Fistulosi Bulbus in Treatise on Cold Damage Diseases was not Daepa but Jokpa, and was dried, and was round shaped bulb bigger than bean. The daily dose was 4, 9, 14 articles in Treatise on Cold Damage Diseases and Synopsis of Prescription of the Golden Chamber. These were estimated equal to 1, 2, 3 Ryang. 1 Ryang equals to 6.5 g in Treatise on Cold Damage Diseases, so the daily dose of Allii Fistulosi Bulbus was estimated 6.5 g, 13.0 g, and 19.5 g. I weighed the middle-sized Allii Fistulosi Bulbuses, the result was remarkably consistent with the estimated numerical value. Conclusions : In Treatise on Cold Damage Diseases, Allii Fistulosi Bulbus was dried bulb of Jokpa of Allium fistulosum Linn$\acute{e}$ and the daily dose was 4 or 9 articles, respectively equaled to 1 Ryang, 2 Ryang and 6.5 g, 13 g.

Objectives: In this study, the safety of alcohol-based hand sanitizers (ABHSs) for quasi-drugs and cosmetics was investigated by analyzing the ethanol content, which is an active ingredient with a sterilizing effect, and methanol, which is toxic. Methods: Forty-one ABHSs were purchased at large supermarkets and online stores. Ethanol quantification was performed by gas chromatography-flame ionization detector, and methanol quantification was performed by headspace-gas chromatography-mass spectrometry. Results: The ethanol content of ABHS in quasi-drugs was 49.6-67.8%, which was suitable for standard manufacturing procedures for external disinfectants, and the ethanol content of ABHS in cosmetics was 9.1-61.3%. The methanol content of ABHS in quasi-drugs ranged from not detected(N.D.)-131.8 ppm, which was suitable for the methanol detection standard of ethanol raw materials in the Korean Pharmacopoeia. The methanol content of ABHS in cosmetics was 23.4-859.7 ppm, which was suitable for the detection limit of methanol in cosmetics. Conclusions: The ethanol and methanol content of ABHS was judged to be safe. When selecting an ABHS to be used for sterilization, it seems necessary to check the content of ethanol, an active ingredient, and use it according to its intended purpose.

Rhubarb is the well-known and frequently used herbal medicine for the treatment of constipation, inflammation, and cancer. As described in the Korea and Chinese Pharmacopoeia, rhubarb consists of the roots and rhizomes of Rheum palmatum, R. officinale, and R. tanguticum. However, the pharmacological differences among rhubarb have not been scientifically established. In the present study, we investigated and compared the inhibitory effects of 70% ethanolic extracts from R. palmatum (RPE), R. officinale (ROE), R. nobile (RNE), and R. franzenbachii (RFE) on the production of inflammatory mediators, nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), interlukin-1beta ($IL-1{\beta}$), and tumor necrosis factor-alpha ($TNF-{\alpha}$) in RAW 264.7 macrophage cells. ROE, RNE, and RFE significantly inhibited the release of NO, $PGE_2$, $IL-1{\beta}$, and $TNF-{\alpha}$. RPE significantly reduced the release of $IL-1{\beta}$, but not NO, $PGE_2$, and $TNF-{\alpha}$. Overall, RFE was found to inhibit the release of $PGE_2$ and $IL-1{\beta}$, to a far greater degree than RPE, ROE, and RNE. Our results indicate that RFE possess the strongest anti-inflammatory activity among 4 tested rhubarb.

Atractylodes japonica and Atractylodes macrocephala belongs to Atractylodes genus and theirs roots are used as 'Baek-chul'(White atractylodes rhizome) in Korea Pharmacopoeia. 'Baek-chul' widely used in traditional herbal remedies in Asia. Concurrently, the 'Baek-chul' demand enormously increased in the market due to the growing interest in favoring health benefits but it is depend on import from China. Thus we conducted breeding research to solve the problems associated with domestically cultivated 'Baek-chul' such as low productivity and low disease tolence. We crossed A. japonica (female parent) and A. macrocephala (male parent) in the greenhouse in September 2000. the next season 119 crossed line seeds were collected and germinated in the green house. Among them we selected the good lines in the same season. then conducted replicated yield trials (RYT) in 2014 to local adaptability test (LAT) in 2015-2016. The results showed that the 'AJM16' line has beneficial charactersitcs like, increased plant height, large rhizome diameter, narrow leaf width compared with a 'Sang-chul' (check cultivar) and varied flower color from A. japonica (female parent). The line 'AJM16' was also exhibited decreased anthracnose symptoms(Colletotrichum gloeosporides Penz.). Simultaneously the root yield of AJM16 was 2,409 kg per are, which was increased 130% higher yield compared to 'Sang-chul' (check cultivar) at three various regions from 2015 to 2016. Therefore, we named AJM16 as new cultivar 'Man-chul'. According the results, we have developed a new Atractylodes spp. hybrid cultivar 'Macn-chul' with high yielding and disease tolerance by National Institute of Horticulture and Herbal Science, RDA, in 2016.

Roxithromycin (RXT), which is an antibiotic used to treat respiratory tract and urinary infections, is official in Korean Pharmacopoeia (KP) and is marketed in various dosage forms including tablet, granule, suspension, and tablet for suspension in Korea. This study presents how a universal and reliable method to quantify RXT in bulk drug and formulations was developed. Effects of factors including column type, buffer concentration, type and concentration of organic solvent, buffer pH, and type and concentration of mobile phase additive, were examined, and some categorical or crucial factors including the types of column, organic solvent, mobile phase additive and the buffer pH were optimized by one-factor-at-a-time approach. Subsequently, concentrations of the buffer and additive and column temperature were optimized by response surface methodology using Box-Behnken design aiming to acquire the RXT peak of good shape. The optimized method employed a Phenomenex Gemini $5{\mu}$ C18 110A ($150{\times}4.60mm$, $5{\mu}m$) maintained at $30^{\circ}C$ with the mobile phase consisting of 25 mM phosphate buffer (pH 6.0) with 0.3 % tetrabutylammonium hydroxide and methanol at a ratio of 37:63 (v/v). Method validation results showed that the developed method was linear, precise, and accurate. Compared to the compendial methods in KP 10 that exhibited a significant tailing of the RXT peak despite using unfavorably high buffer concentrations and were not harmonized among bulk drug and formulations, this method could be universally applied to RXT bulk drug and marketed products in various dosage forms and thus was adopted in KP 11.

Contents of compounds in Rehmanniae Radix change depending on the number of steaming and drying and the drying method. In this study, as an impregnation method for dried Rehmanniae Radix, takju impregnation and cheongju impregnation were carried out and steaming and drying were repeated for 9 times. The changes of 5-HMF and catalpol contents were analyzed according to the number of repetition times to investigate which stage of steaming and drying is preferable. Also, total nitrogen, crude fat, ash, and crude fiber were measured to analyze changes in general components. 5-HMF was not detected in dried Rehmanniae Radix. As a result of repetitive steaming and drying, the content of 5-HMF increased only slightly from 1 to 4-times steaming and drying but increased significantly from 5-times. The catalpol in dried Rehmanniae Radix was not detected after 5 times of steaming and drying. Sucrose, maltose, and glucose were included in dried Rehmanniae Radix before steaming and drying. However, after the process in both Takju impregnation and Cheongju impregnation, galactose and fructose tended to decrease after production and sucrose and glucose tended to decrease after the increase. In this study condition, 6-times and more steaming and drying were appropriate process which met the content criteria (not less than 0.1%) of the Korean Pharmacopoeia (8th edition) for 5-HMF, an index component for quality control of Rehmanniae Radix Preparata.

Objectives : This study aims to examine validity of the following guideline for Zanthoxyli Pericarpium in the Korean Pharmacopoeia regarding foreign materials: "the seeds of Zanthoxyli Pericarpium that are mixed should not exceed 20%." Methods : Varied compliance guidelines for and original plants of Zanthoxyli Pericarpium across countries were compared and contrasted. In order to do this, pharmacopoeias from a number of different countries including Korea were used as references. Results : The weights including seed parts were Z. piperitum 3.48g, Z. schinifolium 2.94g, and Z. bungeanum 2.16g; while the weights of peel parts were Z. piperitum 1.45g, Z. schinifolium 1.69g, and Z. bungeanum 0.98g. In terms of weight, Z. piperitum was the heaviest with its entire part including the seed, whereas Z. schinifolium was the heaviest with its peel part. The proportions of each seed in the whole part were Z. piperitum 58.33%, Z. schinifolium 42.52%, and Z. bungeanum 54.63%. Considering these figures, including seed parts in the guideline up to 20% is inappropriate; however, this guideline is inevitable in order to use seed parts for medicinal purpose. Conclusion : In this article, the author argues if any changes were to made on the guideline for Zanthoxyli Pericarpium with respect to foreign materials - "the seeds of Zanthoxyli Pericarpium that are mixed should not exceed 20%" - its seed part should firsthand be separated from its peel part and be designated as one kind of medicine. Then, revisions on the foreign materials compliance guidelines for Zanthoxyli Pericarpium should also be made.
