Lipids of Job's tears (Yullmoo) were extracted by the mixture of chloroform: methanol (2:1, v/v) and from these lipids, triglycerides were separated by column chromatography (Sephadex G-25 column) and then confirmed by thin layer chromatography (TLC) and reconfirmed by gas chromatography (GC). The triglycerides were fractionated into 6 groups on the basis of their partition numbers (PN) by reverse phase high performance liquid chromatography (HPLC) on a column Shimpack CLC-ODS using tetrahydrofuran-acetonitril (25:75) mixture as a solvent. Each of these collected fractions gave one to two peaks in the GC chromatograms according to the acyl carbon number (CN) of the triglyceride and fatty acid composition of the triglycerides were also analyzed by GC. From the results, the major triglycerides of Job's tears lipids were estimated to be C18:1 C18:2 C18:2 (OLL, 38.2%), C16:0 C18:2 C18:3 (PLLn, 15.7%), C18:1 C18:1 C18:2 (OOL, 12.6%).

The increase of triglyceride in blood can be a signal of an increasing danger of arterial diseases when insulin resistance. diabetes. HDL -cholesterol decrease is accompanied. It is adjusted to triglyceride level in blood by a balance. which seems to be absorbed from VLDL metabolism in liver and by lipoprotein lipase activity. The hyper-triglyceride disease treatment proposal role should match with suppression does into liver or elimination of a triglyceride. (omitted)

This study investigated the effect of lemon balm (Melissa officinalis) extract on improving blood triglycerides according to the extraction solvent using 3T3-L1 cells. Lemon balm was extracted with water (MOW100), 70% ethanol (MOE70), 50% ethanol (MOE50), and 30% ethanol (MOE30). To verify its efficacy on improving blood triglycerides, cell viability, lipid accumulation, triglyceride (TG) content, and expressions of protein kinase A (PKA), adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL), perilipin, and CGI-58 proteins were evaluated. Cytotoxicity was not evident up to an extract concentration of 1 mg/mL. Lipid accumulation and TG content were decreased in a concentration-dependent manner compared to their levels in the control group. When the MOW100 extract was applied at a concentration of 0.2 mg/mL, an inhibitory effect was evident, with lipid accumulation inhibited by 21.3% and TG content reduced by 32.7%. PKA phosphorylation and ATGL HSL and CGI-58 levels were increased. The data indicate that lemon balm extract obtained using water is more efficacious than extracted with ethanol. The aqueous extract shows potential in triglyceride control through lipolysis and lowering triglyceride levels.

The definite mechanism in the control of triglyceride metabolism is not well understood. Nowadays, it has been known that the polymorphism of apolipoprotein C-III $Sst$ I was an important candidate for contributing to the control of triglyceride metabolism. In 298 Korean women aged 30 years or more, the genotypes of apolipoprotein C-III $Sst$ I were statistically compared with total blood cholesterol, triglyceride, high density lipoprotein, fasting blood sugar and hemoglobin A1c. Multiple logistic regression analysis was carried out to compare the odd-ratios of hypertriglyceridemia, hypercholesterolemia and diabetes mellitus with them. The differences among the polymorphic types ($S_1S_1$, $S_1S_2$, and $S_2S_2$) were not statistically significant in the distribution of triglyceride, total cholesterol, high density lipoprotein, fasting blood sugar, and hemoglobin A1c. There were not statistically significant in the odds ratios of the hypertriglyceridemia, hypercholesterolemia, and diabetes mellitus, neither. Those were not statistically significant. This study did not show that there was any association between the polymorphism of apolipoprotein C-III $Sst$ I and various laboratory values-total blood cholesterol, triglyceride, high density lipoprotein, fasting blood sugar and hemoglobin A1c.

The pharmacological effect of Korean-Chinese traditional herbal medicine, Hawangyeonhaedoktang (HT) on experimentally induced-triglyceride accumulation in cultured human hepatocyte HepG2 cells was studied. HePG2 cells were cultured in the Dulbecco's modified Eagle's (DME) medium without (Control medium) or with HT (0.5 mg/mL and 5.0 mg/mL) containing 1 mM oleate, 0.2% bovine serum albumin (BSA), and glucose 4.5 mg/mL for 6 and 24 hours in experiment I and 2 mM oleate, 0.5% BSA, and glucose 4.5 mg/mL for 6, 24 and in hours in Experiment II or 1 and 3 hours in Experiment III. Oleate ［$^{14}$ C］(0.5 $\mu$Ci/mL medium) added as a radioactive lipid precursor in the experiment I. In the experiment I, the intracellular triglyceride concentration was decreased remarkably during incubation for 6 and 24 hours, in a dose-dependent manner. At the same time, HT caused a decrease in the incorporation of ［$^{14}$ C］ oleate into intracellular triglyceride fraction and the secretion of triglyceride labeled with ［$^{14}$ C］ oleate into medium. In the experiment II and III compared to experiment I, the triglyceride accumulation in HepG2 cells was occurred, and HT prevented the accumulation of triglyceride during incubation for 24 and 48 hours. This result suggest that HT prevent the triglyceride accumulation in human hepatocytes by its inhibiting action on the intercellular triglyceride biosynthesis.

An ethanol administration causes hepatic triglyceride accumulation in rats. To assess whether the herbal extract containing Phaseoli radiati semen(herbal extract) inhibit s the triglyceride accumulation in the liver, we determined the hepatic triglyceiide levels in rats fed ethanol and the herbal extract. In addition, the blood ethanol concentrations and the activities of hepatic alcohol dehydrogenase(ADH) and aldehyde dehydrogenase(ALDH) were measured to determine the effects of the herbal extract on alcohol metabolism in rats. The administration of the herbal extract markedly reduced the triglyceride levels elevated by ethanol in the liver as well as in the serum. The herbal extract remarkably lowered blood ethanol concentrations in a dose-dependent manner. The ADH activities decreased by ethanol were recovered to the normal level by the herbal extract treatment. Moreover, the ALDH activities slightly decreased by ethanol increased beyond the normal level by the herbal extract treatment. We conclude that the herbal extract inhibits the hepatic triglyceride accumulation and stimulates alcohol metabolism by preventing ADH and ALDH from inhbition by the ethanol administration in the rat liver.

The triglyceride compositions of peach kernel and apricot kernel oil have been investigated by a combination of high performance liquid chromatography (HPLC) and gas liquid chromatography(GLC). The triglycerides of peach kernel and apricot kernel oil were first separated by thin layer chromatography(TLC), and fractionated on the basis of their partition number(PN) by HPLC on a C-18 ${\mu}-Bondapak$ column with methanol-chloroform solvent mixture. Each of these fractionated groups was purely collected and analyzed by GLC according to acyl carbon number(CN) of triglyceride. Also the fatty acid compositions of these triglycerides were determined by GLC. From the consecutive analyses of these three chromatography techniques, the possible triglyceride compositions of peach kernel and apricot kernel oil were combinated into fifteen and thirteen kinds of triglycerides, respectively. The major triglycerides of peach ternel oil were those of $(3{\times}C_{18:1}\;30.9%)$, $(2{\times}C_{18:1},\;C_{18:2},\;21.2%)$, $(C_{18:1},\;2{\times}C_{18:2}\;10.6%)$, $(3{\times}C_{18:2}\;3.8%)$, $(C_{18:0},\;2{\times}C_{18:1},\;1.8%)$, $(C_{16:0},\;C_{18:1},\;C_{18:2},\;1.5%)$, $(C_{18:0},\;C_{18:1},\;C_{18:2},\;1.1%)$ and those of apricot kernel oil were $(3{\times}C_{18:1},\;39.5%)$, $(2{\times}C_{18:1},\;C_{18:2},\;24.5%)$, $(C_{18:0},\;2{\times}C_{18:2},\;14.2%)$, $(3{\times}C_{18:2},\;2.0%)$.

The effects of age and dietary fatty acid composition on lipid metabolism were investigated in Sprague-Dawley strain male rats. These animals weighing 88.6$\pm$2.2g were fed 10% dietary fat(W/W, 20% of total energy) with 0.5, 1, 2 P/S ratio and in each P/S ratio there were three different levels of n-6/n-3 fatty acid ratio ; 2, 4, 8. The experimental period was 1 month, 6 months and 12 months. The results of this study were as follows. The body weight of rats increased rapidly for the first two months, then increased slowly until 7 to 8 months. After 10 months of dietary regimen their weight decreased. The weight of liver, kidney and epidydimal fat pad increased along with the body weight and then decreased in the 12 months. Plasma total lipid increased with age and it decreased significantly when P/S ratio of dietary fatty acid was high. In creased with age and it decreased significantly when P/S ratio of dietary fatty acid was high. In creasing n-3 fatty acid intake in each P/S ratio resulted in lower plasma total lipid although was not statistically significant. The amount of plasma total cholesterol increased at 6 months, but decreased at 12 months. In case of 1, 12 months, increasing P/S ratio significantly plasma total cholesterol and LDL-cholesterol were decreased and hepatic cholesterol was increased, VLDL-HDL-cholesterol did not changed. The n-6/n-3 ratio did not affect any of theses. The amount of plasma triglyceride and VLDL-triglyceride increased at 6 month then decreased. When the rats consumed higher amount of n-3 fatty acid in each P/S ratio, their plasma triglyceride and hepatic triglyceride increased at 1, 12months.

Effects of the dietary supplementation of Codonopsis lanceolata root on triglyceride and cholesterol levels in the serum, liver, breast muscle and bile in male Cobb$\times$Cobb chicks were investigated. The chicks (15-42 days old) were fed diets supplemented with 0, 0.25 and 0.5% Codonopsis lanceolata root. No differences were observed in body weight, feed conversion ratio, gall bladder weight or abdominal fat deposition among the control group and the two treatment groups. Liver weights were higher in chicks fed a 0.5% Codonopsis lanceolata diet than in those fed the control diet (p<0.05). However, serum levels of both glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) were not different among the three groups. Broiler chicks fed either 0.25% or 0.5% dietary Codonopsis lanceolata root showed decreased serum levels of triglyceride, total cholesterol and low density lipoprotein cholesterol compared to the control group (p<0.05). Supplementation with either 0.25% or 0.5% dietary Codonopsis lanceolata root decreased the triglyceride and total cholesterol levels in liver and breast muscle compared to the control group (p<0.05). Biliary cholesterol increased by 15% in chicks fed 0.5% dietary Codonopsis lanceolata root, suggesting that the biliary excretion of cholesterol had been elevated by dietary Codonopsis lanceolata root (p<0.05). In conclusion, these results indicate that dietary Codonopsis lanceolata root can decrease triglyceride and cholesterol levels in the serum, liver and breast muscle of broilers.

This study was designed to observe the effects of dietary P/S ratio on lipid component in plasma and tissues. Changes in plasma total cholesterol and triglyceride concentration and also cholesterol and triglyceride concentrations in liver, small intestine and aorta were determined in adult rats fed experimental diets providing different dietary P/S ratios as 0.05, 0.5, 1.0, 2.0, 3.0, and 4.0, respectively. The results obtained were summarized as follows; 1. Feed efficiency ratio was not significantly different among six groups at 2nd week. But at 4th week, the higher the dietary P/S ratio the higher the feed efficiency ratio. 2. Plasma cholesterol level was getting higher as increased dietary P/S ratio at 2nd week, But that was significantly decreased as P/S ratio increased at 4th week. 3. Plasma triglyceride level was significantly decreased as increased dietary P/S ratio at 4th week. 4. Cholesterol concentrations in liver and small intestines were getting higher as increased dietary P/S ratio at 4th week, But aortas cholesterol concentration was not influenced by P/S ratio. 5. Triglyceride concentrations in liver and small intestines were significantly increased as increased dietary P/S ratio. On the contrary, triglyceride concentration in aortas was not influenced by P/S ratio.
