The purpose of this study was designed to observe the effects of the feeding Prunus persica Batsch var. davidiana Max. extract on the concentrations of the lipids and blood glucose in the S.D. rats fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, triglyceride(TG), phospholipid(PL) and blood glucose in serum were significantly higher in the cholesterol administration groups (groups BCG (cholesterol+water), BCPG (cholesterol+ Prunus persica 5.0 g% extract) than those in the control group (group BG, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum were remarkably lower in the group BCPG than those in the group BCG. In the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Prunus persica 5.0 g% extract administration group was higher percentage than in the group BCG. The activities of aspartate aminotransferase (AST), alanine aminotransferase(ALT), lactate dehydrogenase(LDH) and alkaline phosphatase (ALP) in serum were rather lower in the Prunus persica 5.0 g% extract administration group(group BCPG) than in the cholesterol diet group(group BCG). From the above research, Prunus persica Batsch var. davidiana Max. were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic rats. And particularly, Prunus persica Batsch var. davidiana Max. was more effective therapeutic regimen for the control of metabolic derangements in adult disease.

Today, men's appearance is an important part of the global fashion industry, including Korea, with such fashion concepts as the Metrosexual and Ubersexual. Domestic and overseas beauty and cosmetics related organizations are using this phenomenon for marketing and researching to improve the function of cosmetics. The purpose of this study was to investigate the effect of Prunus persica L. Batsch leaf extract on the skin condition after clinical application to male subjects with oily skin to determine the possibility of functional cosmetics utilizing this extract. The cleansing bars were prepared by the MP method and the cleansing packs were prepared using natural ingredients. After 8 weeks of application, moisture, oil, erythema, melanin, pH, elasticity and tactile sensation were measured using MPA5. The results showed that there was a statistically significant difference in T-zone moisture and T-zone oil after using the natural cleansing bar, but there was no significant difference between the two groups for other items. However, the statistically significant changes were found in the individual skin condition change items of the subjects in each group, and it was judged that the two kinds of formulations could be used at the same time to have a higher skin improvement effect. Thus, Prunus persica L. Batsch leaf extract demonstrates potential to be used as a functional cosmetics item.

This study was performed to observe the effects of the feeding Prunus persica Batsch var davidiana Max. extract on the improvement of the free fatty acid, creatine phosphokinase and lecithin cholesterol acyltransferase(LCAT) activities in the serum of dietary hypercholesterolemic rats(S. D. strain, male) fed the experimental diets for. 5 weeks. Concentration of electrolyte(Na, K, Cl) in serum were fairly reduced in the group BCP(basal diet + cholesterol + Prunus persica, $5.0\;g\%$ extract) than in the group BCW(basal diet + cholesterol + water). However, no significance was found in the effect of an electrolyte concentration among the groups. Concentrations of free fatty acid, lipid peroxide and creatine phosphokinase activity in serum were significantly higher in the cholesterol administration groups(group BCW, BCP) than those in the control group(group BW, basal diet + water). However, concentrations of free fatty acid, lipid peroxide and creatine phosphokinase activity in serum were remarkably lower in the group BCP than those in the group BCW The LCAT activity in serum was increased in the Prunus persica $5.0g\%$ extract administration group(group BCP) than in the cholesterol of diet group(group BCW). From these results, the Prunus persica Batsch var davidiana Max. extracts were found to be effective on the improvement of the lipid compositions in serum of dietary hypercholesterolemic rats.

Reactive oxygen species(ROS) are produced at a high rate continuously as a by-product of aerobic metabolism. Several lines of evidence provided that ROS appears to cause to develop aging and various diseases. High level of hyaluronic acid with decreased molecular weight has been detected in patients with inflammatory diseases including rheumatoid arthritis. Hyaluronidase is an endohexosaminidase that initiates the degradation of hyaluronic acid with high molecular weight. Prunus persica Batsch var. davidiana Maximowicz has been known as a korean folk medicine for treatment of neuritis and rheumatism. (omitted)

In order to investigate the quality characteristics of Prunus persica Batsch var. davidiana Max. preserved in sugar, the quality characteristics were examined by dividing them into four groups: PS-A (P. persica preserved in sugar mixed with sucrose and oligosaccharides at a ratio of 100:0, w/w), PS-B (P. persica preserved in sugar mixed with sucrose and oligosaccharides at a ratio of 60:40, w/w), PS-C (P. persica preserved in sugar mixed with sucrose and oligosaccharides at a ratio of 40:60, w/w) and PS-D (P. persica preserved in sugar mixed with sucrose and oligosaccharides at a ratio of 0:100, w/w). The results were as follows: pH levels and soluble solid contents of PS-D sample were lower than those of the others, however total acidity value were higher. In case of Hunter's value, the 'L', 'a' and 'b' values of all samples were affected by addition of oligosaccharides. No great difference occurred among samples in reducing sugar contents. Organic acid content was significantly decreased with the lower addition of sucrose. The predominating organic acid components analyzed in all samples were lactic acid 156.15 g/100 g, tartaric acid 72.75 g/100 g and citric acid 32.90 g/100 g. The highest contents of total phenol and flavonoid, and DPPH and ABTS radical scavenging activity were $10.79{\pm}0.55mg\;GAE/mL$, $8.71{\pm}0.06mg\;CE/mL$ and 71.8%, 71.0% for PS-D, respectively. The results of this study indicated the use of oligosaccharides could increase the quality and antioxidant potentials of P. persica preserved in sugar.

Previously , the methanolic extract of peach sees was found to have a strong tyrosinase inhibitory activity in an in vitro assay. Several phenolic compunds were isolated from the seeds by solvent fractionation , Sephadex LH-20 chromatography, and preparative HPLC , and one of them showing strong tyrosinase inhibition was identified as benzoic acid by UV, IR, $^1$H/$^1$$^3$C-NMR, and EI-MS spectrsopy. Benzoic acid (IC50= 250$\mu\textrm{g}$/ml) and L-ascorbic acid (IC50=28$\mu\textrm{g}$/ml), well-known tyrosinase inhibitors. In particular , benzoic acid inhibited markedly the enzymatic browing (melanosis) of apple juices at low concentration of 0.01% and 0.05, comparable to that of L-ascorbic acid (P<0.05). these results suggest that benzoic acid, one of an effective food preservatives, may be potentially useful as a functional alternative to sulfites for the control of melanosis in fruit juices.
