This study was done to know the effect of Giyuetang on the inflammatory response, contact hypersensitivity (CH), and rosette forming capacity of spleen cells. The effects of Jiyutang with Fructus Immaturus Ponciri on the inflammatory response were evaluated by measuring the production of such reactive oxygen intermediate(ROI) as $O_2^-$ and $H_{2}O_2$ in the peritoneal neutrophils and macrophages. The effects of Jiyutang with Fructus Immaturus Ponciri on the CH were evaluated by checking the ear swelling response against dinitrofluorobenzene(DNFB). The administration of Jiyutang with Fructus Immaturus Ponciri on the mouse decreased the amount of ROI in both neutrophils and macrophages. Jiyutang with Fructus Immaturus Ponciri depressed CH without affecting the rosette forming capacity of spleen cells. The results of this study showed that Jiyutang with Fructus Immaturus Ponciri might have anti-inflammatory effects by decreasing the amounts of ROI in the phagocytes and suppressing the CH, without affecting the rosette-forming capacity of spleen cells.

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.

Ponciri fructus, the unripe fruits of Poncirus trifoliata, are widely used in oriental traditional medicine as a remedy for inflammation, gastritis, emesis, digestive ulcers, allergy, and dysentery. To study the anti-wrinkle effects of Ponciri fructus extract (PFE) containing flavanone glycosides, PFE was fermented with Ganoderma lucidum mycelia and its biological activities were investigated. In Ponciri fructus extracts fermented with G. lucidum (G-PFE), polyphenol content was $1,021.00{\pm}0.50{\mu}g/mL$ and flavonoid content was $589.41{\pm}0.21{\mu}g/mL$. G-PFE was found to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and superoxide anion radical by a dose dependent manner, respectively. G-PFE showed higher antioxidant activity than that of PFE. In addition, the photoprotective properties of G-PFE was tested in human dermal fibroblasts (HDF) exposed to UVA radiation. G-PFE inhibited the activity of matrix metalloproteinase-1 (MMP-1) and showed a dose dependent decrease in the expression level of MMP-1. G-PFE also increased collagen biosynthesis in HDF. These results demonstrate that G-PFE could be useful as a potential cosmetic ingredient for anti-wrinkle.

We investigated the effects of Ponciri Fructus (PF) and Aurantii Fructus Immaturus (AI) on the cicular and longitudinal smooth muscle of rat gastric fundus. Methanol extracts of PF (PFM) and AI (AIM), water-fractions (PFW, AIW) and chloroform-fractions (PFC, AIC) of the extracts induced relaxation in the rat fundic circular muscle pre-contracted by U46619. All extracts showed relaxation without significant differences among the extracts. In the longitudinal smooth muscle, PFM and its water fraction, PFW, showed multiphasic effects, fast relaxation and rebound contraction followed by lasting relaxation. AIM and AIW showed diphasic effects, transient contraction followed by lasting relaxation. However, PFC and AIC induced only relaxation in the rat fundic longitudinal muscle contracted by U46619. PFM showed significantly more effective relaxation compared with PFW, AIM and AIW. Hesperidin, flavonoids known as common constituent of PF and AI and it's an aglycon, hesperetin, induced relaxation in both fundic circular and longitudinal smooth muscle pre-contracted by U46619. Poncirin, known as flavonoid content of PF showed also induced relaxation in the both circular and longitudinal smooth muscle pre-contracted by U46619. These results suggest that both PF and AI has relaxing effects on the gastric fundus smooth muscle and its effects might be caused by their flavonoids constituents.

The biological activities of fruits of Poncirus trifoliata have been studied. 70% Ethanol extract of Ponciri Fructus was fractionated with ether, ethyl acetate and n-butanol by turns. The ether fraction showed antibacterial activity on Staphylococcus aureus and inhibited the contractability of the isolated mice ileum. The ethyl acetate and n-butanol fractions showed the anti-edematous effect on the carrageenin-induced edema of rat hindpaw. From the n-butanol fraction, one of the flavonoid glycoside was isolated and identified as poncirin. Ponciri Fructus contained about 6% poncirin which was 5,7-dihydroxy-4´-methoxy flavanone rhamnoglucoside and poncirin showed antiinflammatory activities. Poncirin was considered as the major effective component of Ponciri Fructus.

Objective : To investigate the effect between Fructus Immaturus Ponciri (FIP, the immature fruit of Poncirus trifoliata) and Fructus Ponciri (FP, the ripe fruit of Poncirus trifoliata) on mast cell-mediated immediate-type allergic reactions. Methods : We performed anaphylactic reaction, histamine release, cAMP, $TNF-{\alpha}$, IgE. Results : The aqueous extract of FIP dose-dependently inhibited systemic and local allergic reaction was induced by compound 48/80 or anti-dinitrophenyl (DNP) IgE in a murine model. FIP also significantly inhibited mast cell-dependent ear swelling response induced by topical application of compound 48/80. When mice were orally pretreated with FIP, the plasma histamine levels were reduced in a dose-dependent manner. FIP dose-dependently inhibited histamine release from the rat peritoneal mast cells (RPMCs) was activated by compound 48/80 or anti-DNP IgE. The level of cAMP in RPMCs, when FIP was added, increased compared with that of a normal or control. In addition, FIP had a significant inhibitory effect on anti-DNP IgE-induced tumor necrosis factor-a ($TNF-{\alpha}$) production from the RPMCs and IgE produced by lipopolysaccharide-stimulated murine whole spleen cells or U266B1 as human IgE-bearing B cells. However, FP showed the lower inhibition rate than those of FIP in above all allergic reactions. Conclusion : These data have important implications for our understanding of the clinical effects of FIP and FP on allergic diseases, and FIP is more effective than FP on the allergic reaction.
