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.

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.

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.
굴 패각과 해조펄프를 이용한 항산화 비드의 식품 보존에 관한 연구
류성렬 ( Soung Ryual Ryu ) 한국유화학회 2012 한국응용과학기술학회지 Vol.29 No.4
연구의 목적은 버려진 굴 패각을 재활용하여 감소시키는 것으로 굴 패각과 해조펄프를 이용하여 식품의 보존에 대한 항산화비드를 활용하는데 있다. 이 연구는 두 부분으로 나누었다. 첫 번째는 파일럿 규격조건으로 설계하고 제조하였다. 둘째는 [A],[B],[C-a],[C-b]화합물에 대한 최적제조 조건을 다루어 확립하고 이들 생성물을 분석하였다. 파일럿 규격 제조는 해조펄프의 분자수식합성과/Cl-전분 그리고 그의 다양한 비드 형태들이 극성용매에서 다양한 중량비율로 액상 혼합하여 제조되었다. 부가적으로, 혼합과정에서 해조펄프의 비율이 증가함으로서, 해조펄프/Ag-굴 패각을 섞인 것의 항균성은 감소되었으나 항산화와 비드의 견고성 성질은 증가되었다. 파일럿 규격의 생성라인은 해조 펄프와 Cl-전분을 분자수식으로 합성하였다. 그리고 극성용매를 사용하여 여러 가지 중량비율로 다양한 형식품 보존에 관한 연구태의 비드를 제조하였다. The objective of this research is to reuse and recycle the oyster shell wastes as a useful of antioxidant beads for foodstuff preservation through the treatment of oyster shell and seaweed pulp. This research is divided into two parts. In the first, designing and preparation of pilot scale condition was accomplished. The second part dealt with establishing the optimized manufacturing condition for [A], [B], [C-a], [C-b] compounds, and analyzing these products. The pilot scale preparation was composed of modify synthesized seaweed pulp /Cl-starch and it`s various bead form were prepared with various weight ratios using polar protic solvents. In addition, with increased seaweed pulp content in the blends, antibacterial property values of seaweed pulp/Ag-oyster shell blend was decreased, however, the antioxidant and bead`s solidity properties increased.
