탱자 추출액이 비만을 유도한 흰쥐의 지질강하 및 항산화효과에 미치는 영향을 검토했다. 혈장유리지방산 및 triglyceride 량은 대조군과 비교하여 탱자 처리군이 유의하게 낮은 값을 보였다. 그러나 정상군의 수준까지 나타내지는 않았다. 총콜레스테롤 및 LDL-cho.농도는 탱자 처리군 모두가 대조군보다 현저하게 하락한 값을 나타내었다. HDL-cho.은 대조군을 비롯하여 전 처리군에서 유의한 차이를 나타내지 않았다. 간장내 총콜레스테롤과 triglyceride량은 정자 처리군이 대조군 보다 현저하게 낮은 값을 보였다. 혈장 및 간장의 TBARS 농도는 탱자처리량이 증가함에 따라 감소하였다. GSH-Px, SOD 및 CAT 활성치는 탱자 처리군에서 높은 활성치를 보였다. 그러나 SOD의 활성치는 대조군과 유의한 차이를 나타내지는 않았다.

Objective : To investigate the effects of Poncirus trifoliata Pharmacopuncture on lowering lipid and contents of serum tumor necrosis $factor-{\alpha}$ $(TNF-{\alpha})$ and interleukin-6 (IL-6) in hyperlipidemic rats. Methods : Triglyceride, total cholesterol, $TNF-{\alpha}$, and IL-6 levels in Poncirus trifoliata Pharmacopuncture groups were compared with those in the control group. Results : Concentration of triglyceride and total cholesterol in plasma was decreased in the Poncirus trifoliata Pharmacopuncture groups. In Poncirus trifoliata Pharmacopuncre groups, plasma LDL-cholesterol showed a lower value and HDL-cholesterol showed a higher value than those of the control group. Contents of $TNF-{\alpha}$ was decreased in the Poncirus trifoliata Pharmacopuncture groups. Contents of IL-6, however, were not significantly different. Conclusions : The results suggest that Poncirus trifoliata Pharmacopuncture may have an impact on lipid metabolism to potentially prevent development of diabetes mellitus and accompanying cerebrovascular diseases.

It is well known that Poncirus trifoliata harmonizes the Stomach dissipates the Nodules of Liver and manages Vitality. This herb has been used for stomachache, vomitting, nausea, abdominal distension and swelling of testis in the Oriental Medicine. A major components of Poncirus trifoliata consist of a various flavonoids such as poncirin, naringin, hesperidin, neohesperidin, rhoifolin, poncimarin, poncitrin. Generally pharmacological activities of an oriental medicinal drug may be different due to diverse origin, harvest season and storage Period. In this study, we aimed to measure the contents of poncirin and naringin, major flavonoid of this herb, to determine the quality of Poncirus trifoliata.

Anal therapy is another way of taking medicine It is a traditional pathway but not available in common situation. Nevertheless. It has many benefit and usefulness, it has not treated so much. The dried immature fruit of Poncirus trifoliata L(Ji-Sil) is widely used to treat urticaria, itch and indigestion in traditional Korean Medicine. So this study was carried out to examine the effect of an aqueous extract from immature fruit of Poncirus trifoliate L. on immediate-type allergic reaction by anal administration. Anal administration of Poncirus trifoliata L. showed a marked inhibition rate in systemic immediate-type allergic reaction with a dose of 0.1 - 1 g/kg 1 hr before intraperitoneal injection of compound 48/80. Anal administration of Poncirus tnjoliata L. (0.1 -1 g/kg) significant1y reduced plasma histamine contents induced by compound 48/80. Anal administration of Poncirus trifoliata L. (10 g/kg) also inhibited to $44.6\%$ (P<0.01) local allergic reaction activated by anti-dinitrophenyl (DNP) IgE. In addition, Syzygium aromaticum dose-dependently inhibited the histamine release from the peritoneal mast cells by compound 48/80 or anti-DNP IgE. These results provide evidence that anal therapy of Poncirus trifoliata L. may be beneficial in the treatment of systemic and local immediate-type hypersensitivity by inhibition of histamine release from mast cells in vivo and in vitro.

탱자(Poncirus trifoliata)의 향기성분을 분석하기 위해 gas co-distillation 방법으로 정유를 추출한 후 GC/retention index(RI)와 GC/MS를 이용해 multi-dimensional analysis를 행하였다. Gas co-distillation 방법으로 탱자의 향도 그대로 지니며 기기분석에 적합한 정유를 얻을 수 있었다. 향기성분의 확인작업에는 GC/RI와 GC/MS를 상보적으로 사용한 multi-dimensional analysis가 효과적이었으며 GC/RI로만 확인할 경우 극성이 다른 두 가지 column을 사용해서 신뢰도를 높일 수 있었다. 탱자에 다량 함유되어 있는 향기성분들은 limonene, myrcene, ${\beta}-caryophllene,\;trans-{\beta}-ocimene,\;{\beta}-pinene$, 3-thujene, 7-geranyloxycoumarin 등으로 밝혀졌으며 확인된 30개의 성분 중 cis-3-hexenyl acetate, n-hexyl acetate, 2-methyl acetophenone, elixene 그리고 elemicine 등은 이제까지 감귤류에서는 발견되지 않았던 새로운 성분들이다.

This study was carried out to evaluate cytotoxic effects of Poncirus trifoliata Raf. extract on lymphocytic leukemia tumor (L1210) cell lines. Disruptions in cell organelles were determined by 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide (MTT) assay The comparison of Ic50 Values of Poncirus trifoliata Raf. extract in L1210 cell lines showed that their susceptibility to these fractons decreased in the following order: adriamycin > Fr.4> Fr. 6> Fr. 5> Fr. 3> Fr. 1> Fr. 2 by the MTT assay. In order to develop an antumicrobial agent, Poncirus trifoliata Raf. was extracted wit ethanol, and then it was fractionated with several mobile phase. The antitumor activities of fractions of the ethanol soluble extract was investigated. The minimal inhibitory concentrations (MIC) of fractions of the ethanol soluble extract of Poncirus trifoliata Raf. against microorganisms were also examined. Antimicrobial activities of ampicillin and ketoconazole as references were compared to those of fractions of the ethanol soluble extract of Poncirus trifoliata Raf. The antimicrobial activities of all fractions from the extract had growth inhibition activities against gram-positive bacteria, gram-negative bacteria and fungi $(MIC\;>\;200{\mu}g/ml)$. These results suggest that fraction 4 of the ethanol soluble extract of Poncirus trifoliata Raf. possessed the most antitumorous agent.

Poncirus trifoliata Rafinesque has been used as the immature fruit of the trifoliate orange tree. This study was carried out to investigate the quality change of Poncirus trifoliata Rafinesque depending on packing materials (vacuum packing, PP (polypropylene) packing, gunny sack packing), storage places and storage periods up to 12 months. The change of loss on drying content, content of poncirin were measured during the 12 months. As a result, the loss on drying content was decreased rapidly in gunny sack packing after storage of 12 months at room temperature. The content of poncirin was decreased generally according to storage conditions and its average loss percent was 38.8%.

A high performance liquid chromatography (HPLC) method was developed for simultaneous determination of two major flavonoid glycosides (poncirin and nanringin) in Poncirus trifoliata Raf. by different harvesting times and locations for two years. A SunFire $C_{18}$ column (4.6 mm${\times}$250 mm, 5 ${\mu}M$) was used at $40^{\circ}C$ for the determination of poncirin and naringin. The mobile phase using gradient flow consisted of two solvent systems. Solvent A was 1.0% (v/v) aqueous acetic acid and solvent B was acetonitrile with 1.0% (v/v) acetic acid. Flow rate was 1.0 mL/min and injection volume was 10 ${\mu}l$. The chromatogram was monitored by photodiode array (PDA) detection at 280 nm for the identification of two flavonoid glycosides in P. trifoliata. The contents of the two components in P. trifoliata ranged from 0.32~13.02%.
