Chinese herbal medicine Curcuma longa is used in food, Chinese herbal medicine and parts of medicine. In particular, Curcuma longais also used as spice due to its unique fragrance, and curcumin substance, a Curcuma longa substance, is known as an outstanding anti-cancer substance. Thus, it is a Chinese herbal medicine that is attracting the attention of numerous researchers. This research conducted an experiment, separating substances that are found in Curcuma longa. In particular, curcumin(CUR), activation material,and other effective substances were subjected to extraction, separation and purification to verify effective substance index by production site by leveraging a method of analysis that uses HPLC. Moreover, this research separated herb medicine substances such as imported material and Curcuma aromatica to conduct comparative analysis of substances. Thus, this research was attempted to develop base data for the medicine development as well as identification of substances that may be used as additive for beverages, and to differentiate Korean made from imports. Towards this end, each chemical combination of separated substances are subjected to physical property, IR, ¹H-NMR, GC Mass, HPLC spectrum analysis for publication.

Curcumin (CUR), activation material, is extracted, separated, and purified from Curcuma longa, other effective substances are extracted and separated to conduct anti-cancer test on effective substance among these substances. In particular, Curcumin is used as anti-oxidation, anti-inflammation, and anti-cancer materials. Thus, to check for existence (non-existence) of cancer cells and morphological change, SK-HEP-1, which is adenocarcinoma cell line, was used on 6 well, and 30,000 cells and Chang cell, which is normal cell line, were also used. Curcumin among substances is subjected to processing so that its final concentration levelstands at 10M, 1 mM, and change in cell line was observed. Movement of target subject to observation is as follows, which are subject to verification and publication. A: Chang cell's normal cell, B: change in cell form after 24 hours after processing 10M curcumin onto Chang cell, C: SK-Hep-1 cell's normal cell,and D: growth andgrowth curtailing of cells subjected to 10M curcumin on SK-Hep-1 cell.

An attempt was made to prepare having pyridine derivatives contained chitosan derivatives that is suitable for N-substituted as thiobenzoic acid contained nicotinic acid and pyridinium derivatives side chain form. Those chitosan derivatives showed high selective adsorption abilities in order of Pb>Cd>Cu>Zn>Hg>Cr>Ba>Ag>Pt>Pd ions in mixed solution of various metal ions at pH 4.7. Chitosan derivative were synthesized treating with pyridine and pyridine derivatives to give them a high selectivity in adsorption of metal ions. The chitosan derivatives(6, 7) demonstrated their selectivity on precious metals among various metal ions distinctively. that is chitosan derivatives had a peculiar selective adsorption on Pb, Cr and Cu ions in mixed solution of various metal ions at pH 1.0. The chitosan derivatives are characterized by ^1H-NMR and IR spectrum.

In this study, α-chlorosuccinic acid was synthesized through the reaction of maleic anhydride with HCl(g), (UV)250 nm~300 nm wavelength in presence of CCl4. For the second reaction of N-(monochloro)succinic acid contained glucosamine derivatives(I) was accomplished by a modification of the general acylation using excess α-chlorosuccinic anhydride in the presence of 2% acetic acid with methanol condition as a solvent at elevated temperature(70oC). We considered organic acid derivatives were useful especially for treatment for the cultivating porphyra.
탄화장치 개발에 의한 쑥(Artemisia asiatica) 탄화 유기용액(쑥초액) 제조에 관한 연구

In this study, liquid with carbonized artemisia was developed for the first time that can be used as food additives and outside medicinal agents by burning artemisia species such as Artemisia dubia wall, Artemisia capillaris Thunb, Artemisia montana (Nakai) Pamp), Artemisia keiskeana Miq, Leonurus Japonicus Houtt. etc. In addition, edibility of recovered liquid with carbonized artemisia was verified by comparing the contents according to each ingredient with common refined pyroligneous liquid through the analysis of 9 kinds of organic acid by the species of artemisia, methanol and ethanol. Besides, the result of antimicrobial activities on six kinds of food spoilage and food poisoning bacteria observed by paper disc method for liquid with carbonized artemisia indicated that those two liquids showed strong antimicrobial. At the concentration of 1.5 mg/disc, clear zone for S. sonnei and S. aureus, L. monocytogenes was 13~16 mm, and they showed stronger antimicrobial activities than other strain.

New type of 5-fluorobenzimidazole derivatives was synthesized through the reaction of 4-fluoro-5-(2,6-dimethylmorpholinyl)-2-aminoaniline with 5-nitro-2-furoic acid and 5-methoxy-3-chlorobenzothiophene-2-carboxylic acid in presence of PPA and treatment of OH-. the resulting substituted 5-fluorobenzimidazole derivatives(6), (7) was characterized by high solubility in common polar organic solvents. We considered 5-fluorobenzimidazole derivatives were useful especially for antifungal drugs. These results are discussed from the viewpoints of the chemical and physical structures of the 5-fluorobenzimidazole derivatives.

본 연구는 여러 해조류 소재 중에서 국내 생산량이 많고 연소가 뛰어나 수율이 높은 해초액 화합물을 대량생산 실용화가 가능한 것을 목표로 하며, 해조류인 미역 다시마 톳 기타 김 등을 이용하는 것으로서 주로 원료확보는 폐자원 해조류 등을 이용하여 고온에서 Poly step trap식 건류 공정 적용인 탄화공정을 수반함으로서 생성된 해초 액을 개발하는 연구다. 이를 분리 정제하는 기술적 공정을 개발하고 나아가 시제품을 개발하여 농업, 식품, 비료, 의약품 대체화를 추진함과 동시에 제일 문제시 되고 있는 식품 첨가제를 해결함으로서 고 부가치성 창출과 바이오 생물약제 원료로 개발하고자 하였다. 그래서 해초 액을 추출 분리 및 정제연구를 실시하여 화합물 분석실험을 추진하였다. 그리고 목초액과 성분비교 우위성 입증실험을 성분비교실험을 통해서 비교 검증실험을 추진하였다. The purpose of this study is to process a seaweed resources that is easy to find in Korea and has outstanding phlogistone and high yield seaweed vinegar solution through mass-production and facility development for utilization. The compound uses wasted seaweeds, such as brown seaweed, kelp, seaweed fusiform, and laver, and carbonizes them in high temperature by drying in poly step trap to extract them. In also involves the development of a process that separates and refines the extracts to create a high value-added anti-bacterial bio solution that can replace chemicals in agriculture and industries and even chemical food additives. so, studied separation and refining of seaweed extracts to analyze the compounds. and processed and compared to seaweed vinegar extracts to prove superiority.
