In this study, Artemisia capillaris, which has been used as oriental medicine area and folks remedy, was investigated for effective substance (scopoletin) analysis. As an attempt to develop new functional beverage by using medicinal herb, Artemisia capillaris. Therefore we investigate the effect of scopoletin in Artemisia capillaris on vessel and regional cerebral blood flow (rCBF) of rats. Artemisia capillaris extract was significantly decreased vessel constraction and significantly increased rCBF. Artemisia capillaris has often been cited in medical literature for its medicinal effects. Although the Korean Food and Drug Administration indicated Artemisia capillaris as the In-Jin-Sook which was allowed as a food stuff. From the view point of the subjects who eat In-Jin-Sook products, most of them ingested it for a certain pharmacological efficacy rather than as a beverage or a food. According to this facts, we need develop functional foods using In-Jin-Sook. Also scopoletin, get known to smooth muscle relaxation content was 326.13 ug/g. These results demonstrate that Artemisia capillaris has pharmaceutical effects and balanced nutritional contents. In according with Artemisia capillaris has a sufficiency of the terms use of food stuff in functional foods.

1. Background and Purpose For many years, Sibimikwanjungtang, Yangkyeoksanhwatang and Hyeongbangsabaeksan have been used as a therapeutic agent in constitutional disease. The effects of three prescriptions on the vascular system is not well-known. The purpose of this study is to determine the effects of these prescriptions on blood pressure(BP) and regional cerebral blood flow(rCBF). 2. Methods I injected a vein of rat with extracts of Sibimikwanjungtang, Yangkyeoksanhwatang and Hyeongbangsabaeksan with five kinds of dose and measured BP and rCBF. 3. Results After injected Sibimikwanjungtang, BP was not changed but rCBF was increased in a dose-dependent manner. After injected Yangkyeoksanhwatang, BP was elevated and rCBF was increased in a dose-dependent manner. After injected Hyeongbangsabaeksan, BP was not changed but rCBF was increased in a dose-dependent manner.
