  • Aging is a complex series of multi-organ processes that occur in various organisms. As such, an in vivo study using an animal model of aging is necessary to define its exact mechanisms and identify anti-aging substances. Using Drosophila as an in vivo model system, we identified Crataegus pinnatifida extract (CPE) as a novel anti-aging substance. Regardless of sex, Drosophila treated with CPE showed a significantly increased lifespan compared to those without CPE. In this study, we also evaluated the involvement of CPE in aging-related biochemical pathways, including TOR, stem cell generation, and antioxidative effects, and found that the representative genes of each pathway were induced by CPE administration. CPE administration did not result in significant differences in fecundity, locomotion, feeding amount, or TAG level. These conclusions suggest that CPE is a good candidate as an anti-aging food substance capable of promoting a healthy lifespan.

  • This study was carried out to evaluate the antiobesity effects of Crataegus fructus in 3T3-L1 adipocytes and mice fed a high fat diet (high fat 45% cal). The inhibitory effect of methanol extract from Crataegus fructus on lipid accumulation in 3T3-L1 adipocytes was quantified using Oil red O staining. Compared with the control, lipid accumulation was significantly decreased by 10-25% with treatment with Crataegus fructus extract at a concentration of 600-2,000 ug/ml. Three-week old ICR mice (n=24) were randomly divided into four groups (T0: normal diet, T1: high fat diet, T2: high fat diet and 50 ug of Crataegus fructus extract, T3: high fat diet and 100 ug of Crataegus fructus extract) and were fed an experimental diet for 5 weeks. At the end of the experiment, body weight gain in the T1 group (3.9${\pm}$0.24 g) was higher than that in the T0 group (2.56${\pm}$0.14 g), while body weight gain in the T2 (3.02${\pm}$0.25 g) and T3 (2.58${\pm}$0.16 g) groups was significantly reduced as compared with that of the T1 group. Moreover, liver weight in the T1 (4.8${\pm}$0.17 g) and T2 (4.8${\pm}$0.16 g) groups was significantly higher than that of the T0 (4.05${\pm}$0.16 g) and T3 (4.57${\pm}$0.10 g) groups, while kidney weight was significantly lower than that of the T0 and T3 groups (p<0.05). The levels of total cholesterol and triglyceride in serum in the T2 and T3 groups were significantly decreased compared to the T1 group. These results suggest that Crataegus fructus can be used as functional materials in food and medicine.

  • This study was conducted to evaluate the contents of antioxidative components from pulpy and seed in wild haw (Crataegus pinnatifida $B_{UNGE}$). Pulpy and seed of haw were smashed, then measured for color properties, antioxidative components of ascorbic acid, phytic acid, proanthocyanidin, anthocyanin, total carotene, ${\beta}$-carotene, lycopene, chlorophyll a, b and tannin. The $a^*$, $b^*$ and $C^*$ values of seed were significantly lower than pulpy, but $L^*$ and $H^{\circ}$ values were higher than that of pulpy. Ascorbic acid contents of pulpy and seed were found to be $10.89{\pm}1.69mg/100g$ and $1.45{\pm}0.16mg/100g$, respectively. Phytic acid, proanthocyanidin, total carotene and tannin contents of pulpy and seed were $689.17{\pm}3.63mg/g$, $597.78{\pm}2.93mg/g$; $355.61{\pm}19.39mg/g$, $49.12{\pm}4.97mg/g$; $8.32{\pm}0.42mg%$, $0.80{\pm}0.01mg%$; $7.53{\pm}0.09mg/g$, $1.02{\pm}0.03mg/g$, respectively. Similarly, ${\beta}$-carotene, lycopene, chlorophyll a and chlorophyll b contents of pulpy also displayed higher values than that of seed. On the contrary, anthocyanin content of seed ($4.24{\pm}0.33mg/L$) was remarkably higher than pulpy ($0.99{\pm}0.62mg/L$). The results showed that pulpy could be severed as great natural antioxidant and biohealth functional food.

  • 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 investigate the influences of wild haw (Crataegus pinnatifida $B_{UNGE}$) on lowering blood urea nitrogen (BUN) and creatinine concentrations in dyslipidemic rats. Four groups of rats were fed different diets for 5 weeks: basal diet (BD group), nondyslipidemic diet+feral haw extract (NDF group), dyslipidemic diet (DLD group), dyslipidemic diet+feral haw extract (DFH group). BUN, creatinine and uric acid concentrations were significantly higher in the DLD group than in the BD group. However, DFH group significantly lowered BUN, creatinine and uric acid concentrations compared to the DLD group. Amylase activity was significantly lower in the DLD group than in the BD group, while DFH group significantly higher compared to the DLD group. Lipase activity was also also significantly lower in the DLD group than the other group. Accordingly, these results suggest that haw extract could be effective for improving kidney function in dyslipidemic rats.

  • 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.

  • This research investigates the effect of the Crataegus pinnatifida BGE. var. major N.E. BR(CPVM) on Alzheimer's disease. The CPVM extract suppressed the expression of IL-1 β, IL-6, APP, AChE mRNA in PC-12 cells treated with CT105. The CPVM extract suppressed the AChE activity, and the production of APP significantly in PC-12 cells treated with CT105. The CPVM extract group showed a significant inhibitory effect on the memory deficit for the mice with Alzheimer's disease induced by CT105 in the Morris water maze experiment. The CPVM extract suppressed the over-expression of IL-1 β, TNF- α and ROS in the mice with Alzheimer's disease induced by CT105. This study suggests that CPVM may be effective for the prevention and treatment of Alzheimer's disease.

  • Allergic contact dermatitis (ACD) is a type IV delayed hypersensitivity reaction that results from exposures and subsequent sensitization to an environmental chemical. Crataegus Pinnatifida (CP) is commonly used to improve spleen function, remove retention of food, and promote blood circulation. This study is designed to investigate the effects of CP on ACD induced by 2,4-dinitrochlorobenzene (DNCB) in mice. In this experiment, the effects of CP on changes in body weights, ear and dorsum skin thicknesses, ear weights, clinical aspects on the dorsum skin, histopathological changes, spleen weights, cytokines were investigated. In addition, the effects on the proliferation rates of splenocytes were also investigated in vivo and vitro study. In results, CP spread (CPS) group and CP spread and administered (CPS+Adm) group showed decrease in spleen weights. In CPS+Adm group, dorsum skin thicknesses were decreased significantly compared to control group. CP treatment diminished erythema, desquamation and keratosis which were induced by repeated painting of DNCB. In histopathological observation, spongiosis and edema were diminished in CPS and CPS+Adm group. CP led to decrease in the proliferation rates of splenocytes in vivo and vitro. In conclusion, these data suggest that CP can decrease symptoms of ACD, so CP is useful to treat patient with ACD.
