생쑥의 건조방법에 따른 지방산 변화를 검토하기 위하여 강화도산 생쑥을 陽翰, 陰翰, 熱風陽燥 및 冷凍翰燥시켜 ethyl ether extract함량과 그 구성 지방산의 함량 변화를 조사하였다.<br/> 1. Ethyl ether extract의 함량은 冷凍翰燥된 쑥이 5.68%로 가장 높았고 熱風翰燥된 쑥이 2.45%로 가장 낮았다.<br/> 2. GLC에 의한 지방산 분석 결과 11종의 지방산 중 주된 지방산은 필수 지방산인 linoleic acid와 linolenic acid외에 palmitic acid가 다량 함유되어 식품 영양학적인 면에서 고무적인 것으로 사료된다.<br/> 3. 건조 방법에 따른 건조쑥의 지방산의 종류에는 차이가 없었으나 그 조성은 상이하였다. 즉 冷凍翰燥된 쑥은 酸化되기 쉬운 高度 不飽和脂肪酸(C_(18:2)+C_(18:3))의 함량이 높을 뿐만아니라 低沸點脂肪酸들의 감소가 가장 적었다. 한편 熱風翰燥된 쑥은 低沸點脂肪酸들이 상당량 감소되었으나 高度 不飽和脂肪酸은 陰翰 및 陽翰시킨 쑥보다 다소 안정하였으며 陽翰시킨 쑥의 변화가 가장 현저하였다. This study was carried out to investigate changes in the compositions of fatty acids according to the different drying methods of raw mugwort. Raw mugwort from Kang-wha was dried with four methods such as sundrying, shady sun-drying, heated oven-drying and freeze-drying. Total contents and fatty acid compositions of the ethyl ether extracts from the dried mugworts were examined. Total contents of the ethyl ether extracts showed remarkable differences with drying methods; freeze-dried mugwort had the highest content (5.60%), while oven dried mugwort revealed the lowest content (2.45%). Eleven fatty acids and four unkown peaks were identified by gas-liguid chromatography; major fatty acids were linoleic acid, linolenic acid and palmitic acid. Fatty acids of mugworts dried by 4 different methods were the same in kinds, but different in their compositions. The content of polyunsaturated fatty acids (C_(18:2)+C_(18:3)) was the highest and the loss of low volatile fatty acids was the least in mugwort dried by the freeze-drying method. The volatile fatty acids considerably decreased in oven-dried mugwort. However, the contents of polyunsaturated fatty acids were a little higher in ovendried mugwort than in sun-dried and shady sun-dried mugwort, and the lowest in sun-dried mugwort.

人蔘의 部位別 脂肪酸 組成

최강주(Kang Ju Choi),김만욱(Man Wook Kim),김동훈(Dong Hoon Kim) 한국식품영양과학회 1983 한국식품영양과학회지 Vol.12 No.4

人蔘의 根部(腦頭, 表皮, 胴體皮層, 胴體內層, 支根, 細尾)와 地上部(果肉, 種子, 莖, 葉)의 部位別 지방질의 함량과 그 구성지방산을 조사하였다. 9部位의 遊離脂質과 結合脂質을 합한 총 지방질 함량은 0.91~3.48%였으나 種子는 15.08%로 다른 部位에 비하여 그 함량이 대단히 높았다. gas liquid chromatography에 의하여 14種의 짝수지방산과 4種의 홀수지방산을 분리, 정량하였으며 주된 지방산은 linoleic acid, palmitic acid, oleic acid 및 linolenic acid였다. 部位別 지방산 조성은 현저한 차이를 나타내고 있었으며 특히 種子는 다른 部位들과는 상당한 차이가 있었으며 10種의 지방산만이 동정되었고 oleic acid와 linoleic acid(51.21%와 37.46%)가 다른 部位들보다 상당히 많았다. 또한 種子, 胴體內層 및 胴體皮層에 함유된 遊離脂質은 다른 部位의 脂肪質에 비하여 불포화 지방산의 함량이 높았다. An attempt was made to investigate the lipid contents and fatty acid compositions of the roots (rhizome, epidermis, pith, cortex, branch root, fine root) and aerial parts (seed, flesh of seed, leaf, stem) of ginseng plant.<br/> Total contents of free and bound lipids in nine parts ranged 0.91 to 3.48%, those of the seeds were 15.08%. Fourteen even-numbered and 4 odd-numbered fatty acids were identified and quantified by GLC. The major fatty acids in each part were linoleic, palmitic, oleic, and linolenic acid.<br/> Fatty acid composition of different parts was varied significantly. Fatty acid composition of ginseng seeds was notably different from those of other parts in plant; the amount of oleic and linoleic acids (51.21 and 37.46%) were higher than those of the other parts.<br/> The unsaturated fatty acid content of the free lipid in seed, pith, and cortex were higher than those of the other parts in plant.

최강주(Kang-Ju Choi),김만욱(Man-Wook Kim),이형규(Hyeong-Kyu Lee),김동훈(Dong-Hoon Kim) 한국생약학회 1983 생약학회지 Vol.14 No.2

An attempt was made to investigate free and bound lipid contents and fatty acid compositions of ginseng and its eveven kinds related crude drugs. Contents of free and bound lipids of ginseng were 1.23% and 0.47%, and those of the related crude drugs were 0.31∼13.05% and 0.26∼1.01% respectively. Fourteen even-numbered and 4 odd-numbered fatty acids were identified by GLC in those lipids from ginseng, and the major fatty acids were linoleic, palmitic, oleic and linolenic acids. The crude drugs are notably different from ginseng in kinds and compositions of fatty acids of free and bound lipids. Composition ratios of unsaturated fatty acids were higher in free lipids from ginseng than those of the crude drugs except Won-ji Polygalae Radix).

As a part of studies on the quality control of crude drug preparation, So-Shi-Ho-Tang, index components of Scutellariae Radix were identified by TLC and quantified by HPLC. Wogonin and baicalein were identified in ethyl ether fraction on silica gel plate with benzene/ethyl acetate (1 : 1, v/v). The content of baicalin was determined by HPLC on μ-Bondapak C<sub>18<sub> column with 0.5%-phosphoric acid/ acetonitrile (73 : 27, v/v). Its recovery rate in the extract granules, compared to the content in the Scutellariae Radix, was 52.1±0.7%.

최강주(Kang-Ju Choi),김동훈(Dong-Hoon Kim) 한국생약학회 1985 생약학회지 Vol.16 No.3

Lipid and fatty acid compositions of free lipids and bound lipids from fresh ginseng, red ginseng and white ginseng were studied by means of silicic acid column chromatography, thin-layer chromatography and gas-liquid chromatography. Free lipid and bound lipid contents in those three samples were 1.21 to 1.45% and 0.32 to 0.45%. Neutral lipid fractions in free lipids from the samples were 76.6 to 79.7%, while glycolipid and phospholipid fractions were 11.6 to 14.7% and 8.5 to 8.7%, respectively. The major lipids were triglycerides, sterol esters and hydrocarbons, diglycerides and free sterols in neutral lipids, sterol glucoside, monogalactosyl diglyceride, esterified steryl glycoside, digalactosyl diglyceride in glycolipids and phosphatidyl ethanolamine, phosphatidyl glycerol, phosphatidyl choline and phosphatidyl inositol in phos pholipids. Fourteen kinds of even numbered and four kinds of odd numbered fatty acids were identified in the four lipid fractions (TL, NL, GL and PL) by GLC, and the main fatty acids were linoleic acid, palmitic acid, oleic acid and linolenic acid.

From crude drug preparation(Soshiho-Tang) ginseng sapogenins were identified by TLC and ginsenoside-Rb₁ was determined quantitatively by HPLC. Panaxadiol, pandaxatriol, acid-hydrolysates of ginseng saponin, were identified by TLC with benzene/acetone(4 : 1, v/v). Rf values of which were measured as 0.26 and 0.14, respectively. The content of ginsenoside-Rb₁ was determined by HPLC on Lichrosorb-NH₂ column with CH₃CN/H₂O/n-BuOH(80 : 20 : 10, v/v). Its recovery rate in the extract granules, was as relatively low as 19.8±1.4% compared to the content in raw red ginseng,

장기저장 홍삼의 품질안정성

최강주(Kang Ju Choi),이광승(Kwang Seung Lee),고성룡(Sung Ryung Ko),김경희(Kyung Hee Kim) 한국생약학회 1988 생약학회지 Vol.19 No.3

Samples of red ginseng, which had been manufactured and packaged by the Korean Monopoly Corporation, were stored at ambient temperatures and humidities (12∼28° and 55∼68 percent) for one to nine years to examine their overall quality stability. The proximate compositions, contents of 50% ethanol and water extracts of the samples and the TLC and HPLC patterns of ginsenosides in the samples remained almost unchanged in all cases. The lipids and fatty acids in the samples, which are otherwise susceptible to oxidation, were stable judged on the basis of the changes of the TLC and GLC patterns of the lipids and fatty acids. It was also found that polyunsaturated fatty acids such as linoleic(C18:2) and linolenic acid(C18:3) present in the samples had been very stable during the long storage periods. It, therefore, seems that the autoxidations of the lipid and fatty acids of red ginseng were prevented by antioxidative compounds which will be progressively formed in red ginseng through non-enzymatic browning reactions during manufacturing process and long-term storage.

As a part of studies on the quality control of crude drug preparation (So-Shi-Ho-Tang), index components of Glycyrrhizae Radix were identified by TLC and quantified by HPLC. Specific red spot (Rf=0.47) was identifted in acid hydro lysate of glycosidic fraction on silica gel plate with benzene/ethyl acetate (1 : 1, v%v). The content of glycyrrhizin was determined by quantification of glycyrrhetinic acid by HPLC on μ-Bondapak C<sub>18<sub> column with MeOH/H₂O/HAc (78 : 19 : 3, v/v). Its recovery rate in the extract granules, compared to the content in the Glycyrrhizae Radix, was 83.3±0.7%.
