Objective : To investigate the effects of Yullmoo (Coix lachryma-jobi var. mayuen stapf.) Pharmacopuncture on plasma lipid composition and glucose concentration in hyperlipidemic rats. Methods : ${\beta}-lipoprotein$ free fatty acids, triglyceride and total cholesterol levels in Yullmoo (Coix lachryma-jobi var. mayuen stapf.) Pharmacopuncture groups were compared with those in the control group. Results : Concentration of ${\beta}-lipoprotein$ showed no significantly different in all treatment groups. Concentration of free fatty acids, triglyceride and total cholesterol in plasma were decreased in the Yullmoo (Coix lachryma-jobi var. mayuen stapf.) Pharmacopuncture groups. In the Yullmoo (Coix lachryma-jobi val. mayuen stapf.) Pharmacopuncture groups, plasma LDL-cholesterol showed a lower value and HDL-cholesterol showed a higher value than those of the control group. Contents of glucose were decreased in the Yullmoo (Coix lachryma-jobi val. mayuen stapf.) Pharmacopuncture groups. Conclusions : The results suggest that Yullmoo (Coix lach.yma-jobi var. mayuen stapf.) Pharmacopuncture may have an impact on lipid metabolism to potentially prevent obesity and enhance treatment effect.

The physicochemical properties of starch isolated from Yullmoo (Coix lachrymajobi var. mayuen stapf.) and Yeomjoo (Coix lachryma-jobi L.) were investigated. The average diameters of starch granules of Yullmoo and Yeomjoo were 12.0 microns, both of all, and the shape of these starch granules were hexagon, octagon and round. X-ray diffraction patterns of two samples were A-types and amylose contents of Yullmoo and Yeomjoo starch were 0% and 23%, respectively, iodine affinities of these were 0.08% and 4.2%, respectively, blue values and alkali numbers of these were 0.13 and 0.43, 2.4 and 7.2, and raising power of these were 280 and 20, respectively. Yullmoo starch had higher swelling power than Yeomjoo starch. The increase in optical transmittance of 0.1% suspensions of Yullmoo and Yeomjoo starches occurred at $60^{\circ}C$ and continued up to $75^{\circ}C$ for Yullmoo, $85^{\circ}C$ for Yeomjoo. Amylogram data on 5% of Yullmoo and Yeomjoo starch suspensions showed that gelatinization temperatures and maximum peak heights of Yullmoo and Yeomjoo were $68.5^{\circ}C\;and\;78^{\circ}C$, 920 and 310 B.U., respectiyely. Intrinsic viscosities of Yullmoo and Yeomjoo starches were 1.49 and 1.77, respectively, and interaction coefficients of the two starches were 0.57 and 0.56, respectively The extent of retrogradation determined at $2^{\circ}C$ showed that retrogradation occurred slowly with Yullmoo starch paste tut little with Yullmoo.

The seeds of Coix lachryma-jobi L. var. ma-yuen(yullmoo) were investigated for the free radical scavenging and mushroom tyrosinase inhibitory activities. Brown yullmoo, which contains bran in the seed, has also been evaluated for comparison. After partitioning of the total methanol extracts of yullmoo and brown yullmoo, each organic layer exhibited mild or potent dose-dependent inhibition(about 20-80%) on 1,1-diphenyl picryl hydrazyl(DPPH) free radical with the concentration of $300\;{\mu}g/ml$ to $800\;{\mu}g/ml$. n-Butanol fraction of yullmoo showed the most potent scavenging effect on DPPH free radical. $IC_{50}$ of n-butanol fraction was $423\;{\mu}g/ml$, about six to seven fold higher concentration than standard BHT at the same inhibition rate. As for the tyrosinase inhibitory activity, all of the fractions including the methanol extract exhibited the similar activities even after partitioning. The chloroform fraction of brown yullmoo was found to show the most potent inhibitory activity with an $IC_{50}$ of $321.5\;{\mu}g/ml$.

The viscometric properties of six kinds of waxy starches of Olchal and Hankang(waxy rice), Chalborie (waxy barley), Yullmoo (waxy Job's tears), Chajoe (waxy foxtail millet), Chalsusu (waxy great millet) and Chalocsusu (waxy corn) were investigated. The increase in optical transmittance of 0.1% starch suspensions occurred at $55^{\circ}C$ for Hankang, $60^{\circ}C$ for Olchal, Chalborie, Chajoe and Yullmoo and $65^{\circ}C$ for Chalsusu and Chalocsusu, and further inrreased $70^{\circ}C$ for Hankang and Olchal, $75^{\circ}C$ for Chajoe, Chalsusu, Chalocsusu and Yullmoo and above $85^{\circ}C$ for chalborie. Amylogram on 5%, starch suspensions showed that gelatinization temperature and maximum peak height were 850 B.U. at $62^{\circ}C$ for Hankang, $65^{\circ}C$ and 980 B.U. for Olchae, $64^{\circ}C$ and 1,080 B.U. for Chalborie, and 1,410 B.U. at $69^{\circ}C$ for Yullmoo, and 1,280 B.U. at $71^{\circ}C$ for Chajoe, and 1,260 B.U. at $71^{\circ}C$for Chalsusu and 1,420 B.U. at $70^{\circ}C$ for Chalocsusu. Swelling power of starches was $38{\sim}55$, and Hankang, Olchal, Chajoe, Chalocsusu and Yullmoo starches had higher swelling power than Chalsusu and Chalborie starches. Intrinsic viscosity of them was $1.43{\sim}1.75$ and hardness of them highly relevant to the gelatinization properties.

The retrogradation properties of waxy starches isolated from waxy rice(Shin sun, Tong il), waxy barley(Suwon # 227), waxy indian millet. waxy millet and Jobs tears(Yullmoo) were investigated. The extent of retrogradation determined by the glucoamyase method during freeze-thaw treatment and storage in low temperature$(0{\sim}5^{\circ}C)$ showed that six kinds of waxy starches were very slowly retrograded. The order of the retrogradation tendencies of these starches were waxy indian millet > Suwon # 227 Waxy millet > Yullmoo > Tong il > Shin sun. Waxy indian millet and Suwon # 227 starches were distinctively retrograded compared with other starches. Retrogradation properties observed during freeze-thaw 30 cycles were similar to those of storage for 30 days at $0{\sim}5^{\circ}C$. Suwon # 227, which has been the only recommened variety in our nation, was composed of 15% of non-waxy starch and 85% of waxy starch granule.

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 study was conducted to compare the components such as proximate composition, total dietary fiber(TDF) content, acid detergent fiber(ADF) content, lignin, water binding capacity(WBC), amino acid composition and lipid components from brown Job's tears, dehulled Job's tears, brown Yeomjoo and bran of Job's tears. The results from this study are summerized as follows: Total dietary fiber(TDF) content of Job's tears, brown Job's tears, brown Yeomjoo and bran of Job's tears were 2.70%, 3.86%, 4.33% and 13.3% each. Water-binding capacity(WBC) of TDF and ADF were $2.63{\pm}0.02g\;H_2O/g$ TDF and $5.89{\pm}0.15g\;H_2O/g$ ADF each. In amono acids composition of samples, glutamic acid content was the highest and the next was leucine. Chemical score of leucine in dehulled Job's tears was very high(189), in contrast lysine was very low$(22{\sim}23)$ So lysine was a first limitting amino acid in Job's tears and Yeomjoo. Neutral lipid contents were 90.89%-96.55%, glycolipid contents were 2.35%-7.48% and phospholipid contents were very low. The major fatty acids of lipid fractions were palmitic acid. oleic acid and linoleic acid.
