Citrus aurantium var. amara L., commonly known as 'bitter orange' or 'sour orange', of the family Rutaceae, has traditionally been used in the treatment of various ailments, and it possesses different types of pharmacological properties. As a part of our on-going studies on the plantsfrom the Iranian flora, the extract of C. aurantium var. amara has been studied for its weight lossproperties using the mice model. While the Sep-Pak fraction, 20% methanol (MeOH) in water, of the hydro-methanolic extract of the peels of C. aurantium var. amara fruits, when injectedintraperitoneal (i.p.) at a dose of 10 mg/kg, significantly decreased the level of weight gain of the mice in comparison with control the group (P < 0.01), the Sep-Pak fraction 80% MeOH in water decreased the initial weight of mice by 0.44% in six weeks. The administration of the total extract(10 and 20 mg/kg, i.p.), and the Sep-Pak fractions, 40% and 60% MeOH in water (10 mg/kg, i.p.)did not show any significant change of weight of the test mice. Of the two active fractions, the80% MeOH in water fraction did not show any noticeable adverse effects on mice, and was therefore analysed by reversed-phase preparative high performance liquid chromatography resulting in the isolation and identification of four major components, two coumarins, meranzin hydrate (1) and bergamottin (2), and two flavonoids, xanthomicrol 5,4'-di-methyl ether (tangeritin, 3) and hymenoxin 5,7-di-methyl ether (nobiletin, 4).

Objective : We investigated the effect of Poncirus trifoliata and Citrus aurantium extract in mice with cerulein-induced acute pancreatitis (AP) model. Methods : AP was induced via intraperitoneal injection of cerulein (50 ${\mu}g/kg$) given every hour for 6h. Poncirus trifoliata (PT: 200 or 400 mg/kg) and Citrus aurantium (CA: 200 or 400 mg/kg) extract were injected 1 h before in mice with cerulein-induced AP. Mice were sacrificed at 6 h after last injection of cerulein. Blood samples were taken to determine serum amylase and lipase levels. The pancreas and lungs were rapidly removed for morphological examination, myeloperoxidase assay. Results : PT pre-treatment significantly protected the pancreas and lung damages and reduced the MPO activity and serum amylase in cerulein-induced AP. However, CA pre-treatment did not significantly protected the pancreas and lung inflammation in cerulein-induced AP. Conclusion : These results suggest that PT but not CA could protect the cerulein-induced AP. Conclusion : These results suggest that PT but not CA could protect the cerulein-induced AP.

Tunicates are known to contain biologically active materials and one species in particular, the sea peach (Halocynthia aurantium), has not been thoroughly studied. In this study we aimed to analyze the fatty acids profile of the H. aurantium body wall and its immunomodulatory effects on RAW264.7 macrophage-like cells. The fatty acids were classified into three categories: saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), and polyunsaturated fatty acids (PUFAs). Omega-3 fatty acid content, including EPA and DHA, was higher than omega-6 fatty acids. H. aurantium body wall fatty acids exhibited enhanced immune response and anti-inflammatory effects on RAW264.7 macrophage-like cells. Under normal conditions, fatty acids significantly increase nitric oxide (NO) and PGE2 production in a dose-dependent manner, thereby improving the immune response. On the other hand, in LPS-treated RAW264.7 cells, fatty acids significantly decreased nitric oxide (NO) and PGE2 production in a dose-dependent manner, thereby enhancing anti-inflammatory effects. Fatty acids transcriptionally control the expression of the immune-associated genes, iNOS, IL-1β, IL-6, COX-2, and TNF-α, via the MAPK and NF-κB signaling cascades in RAW264.7 cells. However, in LPS-stimulated RAW264.7 cells, H. aurantium body wall fatty acids significantly inhibited expression of inflammatory cytokine; similarly, production of COX-2 and PGE2 was inhibited. The results of our present study provide insight into the immune-improving and anti-inflammatory effects of H. aurantium body wall fatty acids on macrophages. In addition, our study demonstrates that H. aurantium body wall is a potential source of immune regulatory components.

Phase II 효소계는 자연계에 존재하는 다양한 화학물질과 천연소재들에 의해 유도되며, 이들의 유도는 화학적 발암물질과 그 밖의 여러 가지 독성물질들로부터 생체를 보호하는데 중요한 역할을 한다. 특히, phase II 효소 중 QR은 quinone류 자체에 대한 보호효과가 있고 다른 암예방 효소계와 공통으로 유도되며, 항암 작용이 있는 많은 화합물에 의해 유도되어지기 때문에 암예방 물질 탐색의 지표가 되는 대표적인 효소로 많이 이용된다. 본 연구에서는 제주도에서 자생하는 귤류 중 지각을 이용하여 메탄올추출물을 제조한 후 대표적인 암예방계 효소로 알려진 quinone reductase 및 glutathion S-transferase의 유도 활성을 조사하였다. 우선 QR 및 GST 유도활성 측정에 앞서 각 시료의 Hepa 1c1c7 세포에 대한 독성을 조사하여 시료자체의 세포독성을 관찰하였으며, 이 결과를 바탕으로 QR, GST 유도 활성을 측정할 시 세포독성을 거의 나타내지 않는 각각 시료의 최대 처리 농도를 결정하였다. 총 6개의 지각 분획물 중 mouse 유래 Hepa 1c1c7 세포주에서는 hexane 충과 chloroform 충에서 QR, GST의 활성이 $200{\mu}g/mL$에서 각각 1.8배, 1.5배 이상으로 증가되어 높은 QR 및 GST의 유도활성을 보였다. 따라서 지각의 hexane 층이나 chloroform층에 존재하는 높은 QR및 GST의 유도활성이 나타나는 물질을 분리 정제하여 앞으로 계속적인 연구가 진행되어야 할 것이다.
