This study was conducted to observe the influences of Crataegus pinnatifida BUNGE extract on lipid concentration in hypercholesterolemic rats (Sprague Dawley, male) fed the experimental diets for 5 weeks. Body weight gain was remarkably lower in the Crataegus pinnatifida BUNGE extract intake group than in the hypercholesterolemic rats. Total cholesterol concentration was remarkably lower in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. Whereas, concentrations of HDL-cholesterol, ratio of HDL-cholesterol concentration to total cholesterol were remarkably higher in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. Atherosclerotic index (AI), cardiac risk factor (CRF) were remarkably lower in the extract of Crataegus pinnatifida BUNGE supplement in hypercholesterolemic rats than in the hypercholesterolemic model. From the above research, Crataegus pinnatifida BUNGE extract was effective on the lipid concentrations in sera of dietary hypercholesterolemic rats.

The objective of this study was to investigate the effects of the Crataegus pinnatifida BUNGE extract supplementation of non esterified fatty acid (NEFA), concentrations of serum protein and electrolyte in sera on the hyperlipidemic rats. Concentrations of NEFA and globulin were remarkably lower in the Crataegus pinnatifida BUNGE extract group (HW group) than in the hyperlipidemic group (HD group), but no difference between control group (CO group) and extract of Crataegus pinnatifida BUNGE supplement in control group (NW group). However, concentrations of electrolyte K and A/G were higher in the HW group than HD group. Concentrations of total protein, albumin, electrolyte of total Ca, Pi, Na and Cl were no difference between HW group than HD group. The results indicate that Crataegus pinnatifida BUNGE extract was in the improvement of hyperlipidemic rats.

The fruit of the Crataegus pinnatifida bunge has been known to have a role as a digestive stimulant, and is used for postpartum abdominal pain and women's menstrual pain. It is used for coronary artery disease, angina pectoris, hypertension and hyperlipidemia. Ascorbic acid, hydroquinone, retinoids, alpha-hydroxy acids, kojic acid, azelaic acid have been used for cosmetic whitening and medical depigmentation. To determine whether Crataegus pinnatifida bunge fruit also has whitening and depigmentation effect, tyrosinase inhibition assay was performed with American Crataegus pinnatifida Bunge ethanol extracts, Korean Crataegus pinnatifida Bunge (Cra) ethanol extracts and Arbutin as a positive control as previously described by Korean FDA guideline. Korean Cra fruit ethanol extracts were 1.87 fold more inhibitory function to tyrosinase activity than American Cra in the experimental condition that inhibitory function to tyrosinase activity of Korean Cra Arbutin is 81.8% when compared to that of the standard control Arbutin as 100%. These results suggest that ethanol extracts of Crataegus pinnatifida bunge have significant whitening effects and may provide the basis for development of cosmetic whitening agent and medical depigmentation applications.

The effects of Crataegus pinnatifida bunge powder(CP) on dough characteristics and bread quality were evaluated. Breads were prepared with the addition of 0, 3, 6 and 9% CP to the basic formulation. The pH of dough added with CP ranged from 5.26 to 5.34, while control dough had a pH of 5.80. The loaf volume index of bread prepared with $3{\sim}9%$ CP decreased by $5.4{\sim}16.9%$ Hardness increased with the addition of CP, but the cohesiveness and springiness decreased with the addition of 3 and 6% CP and increased with the addition of 9% CP. Color L value of the bread crust and crumb decreased with CP and color a and b values of the bread crumb increased with CP. The sensory quality of bread with 6 or 9% Crataegus pinnatifida bunge powder, as estimated by shape, flavor and overall quality, was worse than that of control bread, while bread with 3% Crataegus pinnatifida bungs powder had the best quality.

Screenings of potential antioxidant activities of Crataegus pinnatifida BUNGE Major. fruits extracted 80% methanol were performed using four antioxidant assays. Significant differences were observed both in total phenolic contents (TPC) and total flavonoid contents (TFC), DPPH radical scavenging activity, nitric oxide scavenging activity, ABTS radical scavenging assay, and reducing power assay. The total polyphenol content and total flavonoid content in the extract were measured to be $224.4{\pm}0.52$ mg GAE/100 g and $12{\pm}0.25$ mg QE/100 g, respectively. When the tested concentration was $500{\mu}g/mL$, DPPH and ABTS radical-scavenging activities of methanolic extracts were 84.15% and 88.8%, respectively. The reducing power and nitric oxide scavenging activity were increased at the manner of dose-dependently. These results suggest that methanolic extracts of Crataegus pinnatifida Bge. fruits possess excellent radical scavenging activities and may serve as a potential source of natural antioxidant.

Objectives : In the present study, we assessed the effects of the ethanolic extract of Crataegus pinnatifida Bunge on the learning and memory impairments induced by scopolamine using the passive avoidance and the Morris water maze tasks in mice. Methods : The cognition-enhancing effect of C. pinnatifida was investigated using a passive avoidance test, the Morris water maze test and Y-maze test in mice. Drug-induced amnesia was induced by treating animals with scopolamine (1 mg/kg, i.p.). Results : The ethanolic extract of C. pinnatifida (100, and 200 mg/kg) significantly reversed the scopolamine-induced cognitive impairments in the passive avoidance test (p < 0.05). Moreover, C. pinnatifida (200 mg/kg) also improved escape latencies in training trials and increased swimming times and distances within the target zone of the Morris water maze (p < 0.05). On the Y-maze test, C. pinnatifida (100, and 200 mg/kg) also significantly reversed scopolamine- induced cognitive impairments in mice (p < 0.05). Conclusions : The ethanolic extract of Crataegus pinnatifida dramatically possesses the anti-amnestic and cognitive-enhancing activities related to the memory processes, and these activities were parallel to treatment duration and dependent on the learning models.

Based upon the antioxidative effectiveness of ether extracts of defated Crataegus pinnatifida B., phenolic antioxidative components were separated by gel column chromatography and identified by MS and H-NMR. Two or three individual compounds were found in free, soluble and insoluble bound phenolic acids, respectively and they were identified as caffeic acid, protocatechuic acid, phloroglucinol and pyrogallol.

The purpose of this study was to examine the antioxidative activity of feral haw (Crataegus pinnatifida BUNGE) seed extracts using 70% methanol, 70% ethanol, chloroform:methanol (CM, 2:1, v/v), n-butanol and ethyl acetate (EA). The total phenol content of the five extracts ranged from 37.29 mg/g to 55.53 mg/g. Moreover, the content was high in the 70% methanol and, 70% ethanol extracts, but low in the n-butanol extract. On the contrary, the total flavonoid content decreased in the order of n-butanol (2.93 mg/g), EA (2.67 mg/g), 70% methanol (1.00 mg/g), 70% ethanol (0.88 mg/g) and CM (0.67 mg/g) extracts. The $NO_2$ radical scavenging activity, antioxidant activity by ${\beta}$-carotene bleaching assay and, superoxide dismutase (SOD) like ability decreased in the order of 70% methanol, 70% ethanol, CM, EA and, n-butanol extracts; further, a similar tendency was also observed in the total phenol contents. Overall, these results indicated that the antioxidative activity of feral haw seeds was closely related to the total phenol and flavonoid contents. Therefore, haw seeds might be usefully applied to natural antioxidants as well as functional foods.

This study was performed to investigate enhancement of antioxidant activities of Crataegus pinnatifida Bunge fruit by different extraction processes. Extracts were SE (stirrer extraction; 70% ethanol extract at $25^{\circ}C$, control), RE (reflux extraction at $60^{\circ}C$), and USE (ultrasonification for 3 h at $60^{\circ}C$ with 70% ethanol), respectively. Compared to SE, total phenolic and flavonoid contents in USE increased to 104.03% and 302.4%, respectively. USE showed the highest activity at 1.0 mg/mL concentration for 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity. Our results suggest that extracts from the ultrasonification process have relatively high antioxidative activities, and that fruit of Crataegus pinnatifida Bunge could be considered as a candidate functional antioxidant agents. These results would be useful for chemical and biological studies on natural plants and its products.
