Objectives : Evodia officinalis DODE (EO), an herbal plant, has been widely used in traditional Korean medicine for the treatment of vascular diseases such as hypertension. The crude extract of EO contains phenolic compounds that are effective in protecting liver microsomes, hepatocytes, and erythrocytes against oxidative damage. But EO has been little found to have an anti-inflammatory activity. We investigated anti-inflammatory activity of EO in RAW 264.7 cells and human umbilical vein endothelial cells (HUVECs). Methods : Cytotoxic activity of EO on RAW 264.7 cells was investigated by using 5-(3-caroboxymeth-oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. The nitric oxide (NO) production was measured by Griess reagent system. And proinflammatory cytokines were measured by ELISA kit. The levels of intracellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) expression were measured by flow cytometer. Results : EO decreased LPS-induced NO production in RAW 264.7 cells. The inhibitory activity of EO on LPS-induced NO release is probably associated with suppressing TNF-${\alpha}$, IL-6 and MCP-1 formation. These results indicate that EO has potential as an anti-inflammatory agent. Moreover, EO decreased TNF-${\alpha}$-induced IL-8, IL-6 production, and ICAM-1 and VCAM-1 expression in HUVECs. Conclusions : EO inhibits TNF-${\alpha}$-induced inflammation via decreasing cytokines production and adhesion molecules expression. These results indicate that EO has potential as an anti-inflammation and anti-artherosclerosis agent.

We reported that neurotoxicity may contribute to cyanide-induced neuronal injury. Cyanide stimulates the release of glutamate which can activate glutamate receptors to propagate excitotoxic processes. We examined the role of plant extracts in mediating the cyanide-induced cytotoxicity and report here that the cytotoxicity assessed in SK- N-SH cell cultures by measuring lactate dehydrogenase (LDH) in the culture media was significantly blocked by Evodia officinalis MeOH extract (OMU). Also, when OMU was treated in NaCN level cultures, the neurite outgrowth was regenerated as much as in the treatment of NaCN only. These results indicate that OMU treatment were not only protected the neurons against NaCN-induced damage but also regenerated the neurite outgrowth of neuroblastoma cells.

Preliminary screening test of modulators for multidrug resistance with 400 medicinal plants was carried out by using human multidrug resistance cell line, KB-V1. Among active medicinal plants, the unripe fruits of Evodia officinalis showed a potent modulating activity of MDR. From MeOH extract of this plant, we isolated two indole alkaloids, rutaecarpine (1) and evodiamine (2), by repeated silicagel column chromatography. Rutaecarpine increased the cytotoxicities of vinblastine and taxol against multidrug resistance cells, but evodiamine showed no modulating activity in spite of its potent cytotoxic activities.

Four alkaloids (1-4), three quinolone alkaloids (5-7), and three flavanoid glucosides (8-10) were isolated from the fruits of Evodia officinalis Dode, and their structures were determined from chemical and spectral data. Compounds, 3, 8, 9 and 10 were isolated from this plant for the first time. Of these compounds, 1-3 and 5-7 exhibited moderate cytotoxicities against cultured human colon carcinoma (HT-29), human breast carcinoma (MCF-7), and human hepatoblastoma (HepG-2). Compound 8 showed strong inhibitory effects on DNA topoisomerases I and II (70 and 96% inhibition at a concentration of $20\;{\mu}M$, respectively).

The MeOH extract of Evodiae Fructus exhibited a significant inhibition on the acetylcholinesterase (AChE) and butyrylcholinesterase (BChE), in a dose dependent manner, respectively. The extensive bioactivity-guided fractionation process with the MeOH extract finally isolated four compounds, as rutaecarpine (1), evodiamine (2), limonin (3) and dehydroevodiamine (4). Among them, compound 2 exhibited specific inhibitory activity on BChE with the $IC_{50}$ values 1.7 ${\mu}g/ml$, whereas compound 4 showed the potent inhibition upon both AChE and BChE.

The effects of MeOH extracts from 28 herbal medicines on monoamine oxidase (MAO) activity were investigated. MAO was purified from mouse brain and its activity was determined by fluoro-photometry using kynuramine as a substrate. Three MeOH extracts, Coptis japonica, Cinnamomum cassia and Poncirus trifoliate from the herbal medicines showed a strong inhibitory effect with less than $100\;{\mu}g/ml$ in their inhibitory amounts of $50\%$ ($IC_{50}$ values) on MAO activity. Four MeOH extracts including Evodia officinalis exhibited a mild inhibition of MAO activity with $100-200\;{\mu}g/ml$ in their $IC_{50}$ values.

The fruit of Evodia officinalis (Rutaceae) is known for containing a number of indoloquinazoline and quinoline type alkaloids. Evodiamine, evocarpine and rutaecarpine are the major constituents of Evodiae Fructus. These alkaloids were isolated and determined by forming complex compounds from Evodiea Fructus. For the determination of these alkaloids, a new spectrophotometric method was developed with a simple and selective sample clean-up using thiocyanatocobaltate [II] complex ion. The absorbance of alkaloidal complex in 1.2-dichloroethane solution was measured at 625 nm. A calibration curve for the alkaloids isolated from Evodia Fruit was linear over the concentration range of $1.0{\sim}6.0\;mg/ml$. The method proved to be rapid, simple and reliable for the isolation and the determination of the alkaloids in Evodiae Fructus.

Although significant progress has been made during the past four decades in the treatment of human neoplastic disease, effective chemotherapeutic treatments are nevertheless far from satisfactory to patients suffering from cancer, particularly to those with the stomach cancer which is most prevalent in Korea. To find out the effective anticancer drugs, especially human stomach cancer, we tested cytotoxic activities of several medicinal herbs against human stomach cancer cell line, SNU-1. Evodia officinalis, Melia toosendan, Sinomenium acutum, Galla Haeepensis, Celastrus orbiculatus and Taxus caespitosa showed a significant cytotoxic activities.
