Effects of 1% dietary orotic acid on triglyceride metabolism were examined in SD-rats and Kud: ddY mice. When rats were fed semisynthetic diet containing 1% orotic acid and n-6 polyunsaturated fatty acid (linoleic acid), the hepared diet. In contrast to rats which respond to orotic acid consumption with increases in hepatic triglyceride content, mice did not so respond. The rats-limiting step in triglyceride synthesis is catalyzed by the enzyme phosphatic acid phosphohydrolase (EC3.1.3.4) which is present in the liver cytosol and microsomes of rats fed oroic acid diet. This finding suggests that the activity of this enzyme may play a tole in the fatty liver formation in rats.

Gamigwaruhaebaekwhanggum-Tang (GGHWT) have been evaluated for antihyperlipidemic effects on experimental hyperlipidemic rats and mice induced by Triton WR-1339, com oil and high cholersterol-diet. Especially, GGHWT is formulated with Trichosanthis Fructus, Pinelliae Tuber, Aurantii Immaturus Fructus, Magnoliae Cortex, Allii Macrostemi Bulbuls, Cinnamomi Ramulus and Scutellariae Radix. Oral administration of GGHWT at 500 mg/kg/day for 3 days significantly inhibited the increase of serum triglyceride and LDL-cholesterol, liver triglyceride in hyperlipidemic rats induced by Triton WR-1339. And, GGHWT significantly inhibited the increase of serum triglyceride in hyperlipidemic rats induced by corn oil. Also, administration of GGHWT (500 mg/kg, once daily for 1 week, p.o.) prevented the increase of serum total cholesterol, triglyceride, LDL-cholesterol, liver total cholesterol and triglyceride in 1% cholesterol-diet fed mice. These results suggest that GGHWT is effective for the treatment of hyperlipidemia.

The purpose of this study was to investigate the effects of wax gourd on weight, triglyceride, leptin and fat cell size in rats fed a high-fat diet. Male Sprague Dawley rats were fed an experimental diet containing total dietary fat at 40% of calories with wax gourd 0%, 5%, 10% and 15% (w/w) for 4 weeks. Weight gain and triglyceride level fell significantly in the 15% wax gourd group compared to the control group. Epididymal fat pad, abdominal fat and perirenal fat tended to decrease in the 15% wax gourd group. Leptin and free fatty acid level were not significantly different among the groups. Fat cell size significantly decreased in the 10% and 15% wax gourd groups compared to the control group. Weight gain correlated positively with visceral fat masses and the levels of leptin and triglyceride. Fat cell size significantly correlated with visceral fat and leptin level. Therefore, the 15% wax gourd diet substantially reduced weight, triglyceride and fat cell size. (Korean J Nutrition 36(5): 446∼451, 2003)

A Study was carried out to elucidate the triglyceride compositions of the red pepper seed oils harvested from two different areas. The oil was extracted from the red pepper seed with nhexane. Each triglyceride of the oil was separated by thin layer chromatography (TLC) and fractonated by reverse phase high performance liquid chromatography (HPLC) on the basis of acyl carbon numbers, and partition number group(PN) and fatty acid composition of triglyceride were analyzed by gas liquid chromatography (GLC). From the results, it was found that the red pepper seed oils of the Chungsong and Youngyang areas consisted of 14 and 18 kinds of triglycerides, respectively. The red pepper seed oil of the Chungsong area consisted of (C18:2, C18:2, C18:2=41.0%), (C16:0, C18:2, C18:2=37.1%), and that of the Youngyang area consisted of (C18:2, C18:2, C18:2=41.0%), (C16:0, C18:2, C18:2=36.3%) and (C16:0, C16:2, C18:2=8.4%), as the major triglycerides.

Triglyceride compositions of cottonseed, soybean, sesame, perilla corn and rapeseed oils have been determined by a high performance liquid chromatographic analysis. An optimum condition was obtained by using a ALC/GPC 244 type, from Waters Association, Japan with $\mu$ Bondapak $C_{18}(1/4^{'}\times1^{'})$ column. A similar distribution pattern of triglycerides was found in cottonseed, soybean, sesame, rapeseed and corn oils. It was noted that $C_{40}$, $C_{42}$ and $C_{44}$ were the major components in these seed oils, except perilla oil. The results showed that contents $O_{40}-C_{48}$ triglyceride types in cottonseed, sesame and corn oil were within $2.23{\sim}41.24%$ and $C_{38}-C_{48}$ triglyceride types in soybean oil were within $3.01{\sim}10.02%$ and $C_{34}-C_{46}$ triglyceride types in rapeseed oil were within $2.38{\sim}28.68%$.

The effects of Temperature on the removal of triglyceride were studied with soaps having various chain lengths of alkyl group. Cellophane, polyester film and alkali-treated polyester film were soiled with tripalmitin, tagged with 0" and detergency was evaluated by analysing the tripalmitine on the fabric before and after washing by means of liquid scintillation counting. The results were as following: 1) Triglyceride was completely removed from cellophane in distilled water without surfactant at any temperature, because of the hydrophillic nature of cellulose. The detergency of triglyceride from polyester film fully depended on the state of tripalmitin. The detergency of alkali treated polyester film was better than that of untreated polyester film at lower temperature due to increased hydrophillcity, but worse at higher temperature due to the diffusion of molten tripalmitin into the grooves, formed by alkali treatment. 2) The detergency from polyester film was increased with elevating temperature and after reaching some optimum detergencies, the detergencies were rather decreased with increasing temperature. The temperatures of optimum detergency were shifted to higher with increasing chain length of alkyl group. 3) When the soiled film was baked at $60^{\circ}C$ and $70^{\circ}C$ for 20 min, the detergency vs. temperature was much the same as the case of without-baking. These results indicate that the detergency of triglyceride was largely correlated with the suspending power of surfactants at low temperature and with state of soil and hydrophilicity of substrates with elevating temperature.

Ojectives : Cheonggukjang(natto) is known to have anti-hyperlipidemic action. This study was designed to investigate whether Herbal-cheonggukjang (HC, Herbal-natto) is more effective than cheonggukjang only, Methods : We investigated anti-hyperlipidemic effects of HC in hyperlipidemic rats induced by high-fat diet in terms of observation on levels of total cholesterol, HDL-cholesterol and triglyceride in serum. HC was made by cheonggukjang added Codonopsis Lanceolata, Houttuynia cordata and Lentinus edodes in indicated concetrations. Results : In this experiment, hyperlipidemic rats showed elevated levels of total cholesterol and triglyceride, and also showed lowered level of HDL-cholesterol. Oral administration of HC decreased levels of total cholesterol and triglyceride, Cheonggukjang(natto) did not affect levels of total cholesterol, HDL cholesterol and triglyceride. Conclusions : In these results, oral administration of HC decreased total cholesterol and triglyceride effectively. These results demonstrate that HC is useful to modulate cholesterol and triglyceride in serum.

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 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.

The present study was conducted to elucidate the triglyceride composition of walnut oil. The triglycerides were separated by thin layer chromatography (TLC) and fractionated on the basis of partition numbers by reverse phase high performance liquid chromatography (HPLC) on a column packed with $\mu$-bondapak $C_{18}$ using methanol-chloroform mixture as a solvent system. Each of these collected fractions was fractionated again on the basis of acyl carbon number of triglyceride by gas liquid chromatography (GLC). The fatty acid composition of triglycerides for each partition numbered group was also analyzed by GLC. From the results, it was found that walnut oil consists of ten kinds of triglycerides, and the patterns of major ones in walnut oil were as follows: 53.3% of $(C_{18:2},\;C_{18:2},\;C_{18:2})$, 10.1% of $(C_{18:1},\;C_{18:2},\;C_{18:2})$, 5.4% of $(C_{18:1},\;C_{18:1},\;C_{18:2})$, 4.3% of $(C_{18:1},\;C_{18:2},\;C_{18:3})$, 3.9% of $(C_{18:0},\;C_{18:2},\;C_{18:2})$, 2.0% of $(C_{18:0},\;C_{18:1},\;C_{18:2})$, 1.8% of $(C_{18:0},\;C_{18:2},\;C_{18:2})$.
