To prevent and treat the osteoporotic fracture, more attention should be paid in old age patients. Osteoclast which has ability to bone resorption is originated from hematopoietic cell line and plays a key role osteoporotic bone loss. Rubi Fructus has been widely used in Oriental medicine. Extracts of the leaves and fruit of Rubus species have been used in various countries as natural remedies to treat diabetes, infections, colic, and burns. However, the effect of extract of Rubi Fructus (fruit of Rubus coreanus Miq.) in osteoclast differentiation remains unknown. Thus, we evaluated the effect of Rubi Fructus on receptor activator of nuclear factor-kB ligand (RANKL)-induced osteoclast differentiation. Here we found that Rubi Fructus significantly inhibited osteoclast differentiation induced by RANKL. Rubi Fructus suppressed the activation of p38 pathway and NFkB in bone marrow macrophages (BMMs) treated with RANKL. Also, Rubi Fructus significantly inhibited the mRNA expression of c-Fos, tartrate-resistant acid phosphatase (TRAP), osteoclast-associated receptor (OSCAR), nuclear factor of activated T cells (NFAT)c1 and cathepsin K in BMMs treated with RANKL. Particularly, Rubi Fructus greatly inhibited the protein expression of c-fos and NFATc1. especially in the case of NFATc1 expression, a master transcription factor of the differentiation of osteoclasts is very important step for osteoclastogenesis. Taken together, our results demonstrated that Rubi Fructus may be useful treatment option of bone-related disease such as osteoporosis and rheumatoid arthritis.

This study was performed to investigate the antimicrobial effect of the Forsythiae Fructus extracts against food-borne pathogens. First, Forsythiae Fructus was extracted with methanol at room temperature and the methanol extracts were fractionated by using petroleum ether, chloroform, ethyl acetate, and methanol. The antimicrobial activity of the Forsythiae Fructus extracts was determined by using a paper disc method against food-borne pathogens and food spoilage bacteria. The methanol extracts of Forsythiae Fructus showed the highest antimicrobial activity against Salmonella paratryphimurium and Salmonella typhimurium. A synergistic effect in inhibition was observed when Forsythiae Fructus extract was mixed with Ulmus davidiana Japonica extract as compared to each extract alone. Finally, the growth inhibition curves were determined by using ethyl acetate extracts of Forsythiae Fructus against Shigella flexneri and Salmonella paratyphimurium. The aqueous extract of Forsythiae Fructus had strong antimicrobial activity against Staphylococcus epidermidis at the concentration of 10,000 ppm. At this concentration, the growth of Shigella fexneri was retarded for more than 24 hours and for up to 12 hours for Staphylococcus epidermidis. In conclusion, the methanol extracts of Forsythiae Fructus efficiently inhibited Staphylococcus epidermidis and Shigella flexneri.

The purpose of this study was to examine the qualities of muffins made with 0, 2, 4, 6, and 8% Corni fructus powder. The height of the muffins did not significantly differ between the sample groups; however, the weight of the control group was higher than that of the test samples containing Corni fructus powder. The volume and specific loaf volume of muffins decreased with the addition of Corni fructus powder. The baking loss of the samples containing Corni fructus powder was also higher than that of the control group. The moisture content of the control group was 19.88%, whereas that of the test samples ranged from 16.72~21.01%. The pH of batters and muffins of the test samples were lower than those of the control group. For DPPH radical scavenging activity, the control group measured 11.46%, whereas the test samples ranged from 22.63~53.33%. The L and b values of the crust and crumbs decreased, but the a value was increased significantly by the addition of Corni fructus powder. Examination of the textural properties revealed the hardness, gumminess and brittleness of muffins containing Corni fructus powder were significantly higher than those of the control group. In term of overall preference, the sensory evaluation scores of groups containing 2% and 4% of Corni fructus powder did not show significant differences compared to the control group. Based on the above results, using Corni fructus powder at less than 4% would be appropriate for making muffins.

The immature fruits of Poncirus trifoliata L. or Ponciri fructus (PF), well known as 'Jisil' in Korea, have been used against allergic diseases for generations, and still occupy an important place in traditional Oriental medicine. Anti-allergic effects of this fruit have been investigated in a few experimental models. Immunoglobulin E (IgE) is the principal immunoglobulin involved in immediate hypersensitivities and chronic allergic diseases. The effect of an aqueous extract of PF on in vivo and in vitro IgE production was investigated. PF dose-dependently inhibited the active systemic anaphylaxis and serum IgE production induced by immunization with ovalbumin, Bordetelia pertussis toxin and aluminum hydroxide gel. PF strongly inhibited interleukin 4 (IL-4)-dependent IgE production by lipopolysaccharide-stimulated murine whole spleen cells. In the case of U266 human IgE-bearing B cells, Ponciri fructus also showed an inhibitory effect on the IgE production. On the other hand, mast cell hyperplasia can be causally related with chronic inflammation. Stem cell factor (SCF), the ligand of the c-kit protooncogene product, is a major regulator and ohernoattractant of mast cells. Ponciri fiuctus (1 mg/mL) significantly inhibited the SCF-induced migration of rat peritoneal mast cells (RPMCs). RPMCs exposed to SCF (50 ng/mL) resulted in a drastic shape change with a polarized morphology while the cells exposed to Ponciri fructus (1 mg/mL) remained resting, with little or no shape alteration. The drastic morphological alteration and distribution of polymerized actin were blocked by pretreatment with Ponciri fructus. In addition, Ponciri fructus inhibited both TNF-alpha and IL-6 secretion from RPMCs stimulated with SCF. These results suggest that Ponciri fructus has an anti-allergic activity by inhibition of IgE production from B cells. These findings also provide evidence that Ponciri fructu inhibits chemotactic response and inflammatory cytokines secretion to SCF in mast cells.

This study was to investigate the effect of Ponciri Fructus ethanol extract on the melanogenesis. The Ponciri Fructus markedly decreased melanin contents of B16F10 cells at a dose of $80{\mu}g/m{\ell}$. It was observed that the color of cell pellets was totally whitened compared with the control. The treatment of Ponciri Fructus inhibited tyrosinase activity, regulate melanin biosynthesis as the key enzyme in melanogenesis. Regarding protein levels of the melanogenic enzymes, the Ponciri Fructus dose-dependently decreased tyrosinase and TRP-1 protein levels, and tyrosinase and TRP-1 were detected in similar manner. These results suggest that the Ponciri Fructus ethanol extract exerts its depigmenting effects through the suppression of tyrosinase and TRP-1.

Objective : Anti-inflammatory effects of the extract of Lycii Fructus on lipopolysaccharide (LPS)-induced inflammation in RAW 264.7 macrophage cells were investigated. Method : In order to assess the cytotoxic effect of Lycii Fructus on the raw 264.7 macrophages 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay was performed. Reverse transcription-polymerase chain reaction(RT-PCR) analysis of the mRNA levels of tumor necrosis factor-$\alpha$(TNF-$\alpha$) and inducible nitric oxide synthase(iNOS) was performed in order to provide an estimate of the relative level of expression of these genes. The protein level of the inhibitor of nuclear factor-${\kappa}B(I{\kappa}B)$ and nuclear factor-${\kappa}B$(NF-${\kappa}B$) activity was investigated by Western blot assay. NO production was investigated by NO detection. Result : Lycii Fructus suppressed NO production by inhibiting the LPS-induced expressions of iNOS and TNF-$^-\alpha$ mRNA and iNOS protein in RAW 264.7 macrophage cells. Also, Lycii Fructus suppressed activation of NF-${\kappa}B$ in the nucleus. Conclusion : These results show that the extract of Lycii Fructus has anti-inflammatory effect probably by suppressing iNOS expressions through the down-regulation of NF-${\kappa}B$ binding activity.

Skin wrinkle formations are associated with collagen synthesis and matrix metalloproteinase-I(MMP-1) activity. This study was carried out to find out skin wrinkle reducing components in Torilis Fructus. Torilis Fructus were extracted with 70% ethanol and the ethanol extracts were systematically fractionated with n-hexane, ethylacetate, n-butanol and distilled water. Among them, antiwrinkle component from n-hexane fraction was purified by several column chromatographies and HPLC, which identified as torilin by $^1H-NMR,\;^{13}C-NMR$ and ESI-MS. To determine cell viability, collagen biosynthesis and MMP-1 activity, human dermal fibroblast was treated with 1-5 ppm concentrations of Torilis Fructus extract fraction and torilin. Cell viability was showed 84-102% at all group treated with 1-5 ppm. Collagen synthesis was increased in all group, especially torilin-treated group was highest amount. Active forms of MMP-1 were decreased in all group. From these results, we consider that Torilis Fructus have several antiwrinkle components and torilin may be one of the effective components.
