To develop an whitening cosmetics, we isolated the melanogenesis inhibitors from the unripe fruits of Poncirus trifoliata (Rutaceae). Isolated compounds were identified as poncirin(l), naringin(2), bis(2-methylheptyl)phthalate(3), avenalumic acid methyl ester(4) by comparison of physical and spectral data with those reported in the literature. Among the isolated compounds, bis(2-methylheptyl)phthalate showed most potent inhibitory effect on the melanogenesis in cultured B-16 mouse melanoma cell lines$(IC_{50},\;36.8\;{\mu}M)$ compared with kojic acid$(IC_{50},\;150\;{\mu}M)$.

The five flavonoids, isoqueritrin, juglanin, astragalin and 2-O-trans-p-coumaroyl astragalin were quantitatively analyzed in the leaves, unripe- and ripe fruits of four Korean Rubus species including Rubus crataegifolius, R. pungens var. oldhami, R. parvifolius, and R. coreanus belonging to the Rosaceae family. The HPLC analysis demonstrated that flavonoids are more abundant in the leaves than in the fruits. In the four Rubus species, ripe fruits generally contained similar or more amount of flavonoids than in unripe fruits. In particular, the quantity levels of total flavonoid (49.81${\pm}$0.50 mg/g) and isoquercitrin (35.08${\pm}$0.37 mg/g) were highest in the leaf of R. crataegifolius. In addition, the content of the flavonoids were quite low in the unripe fruits of R. coreanus that is most widely used as Rubi Fructus.

The subcronic toxicity of BDR-29, a herbal preparation of Cassiae Semen, Prunellae Spica, Tribuli Fructus, and Uncariae Rhamulus et Uncus, was examined in male and female Sprague-Dawley rats. Rats were treated with the test substance at a dose 5 mg/kg, 50 mg/kg and 500 mg/kg intragastrically for 13 weeks. No death and abnormal clinical signs were observed throughout the administration period. There were not significantly different from control group in net body weight gain, food and water consumption, organ weight, gross pathological findings, and urine analysis among the groups rats treated with different doses of the BDR-29. Hematological findings and biochemical examination revealed no evidence of specific toxicity related to BDR-29. From these results, no observation effect level (NOEL) of BDR-29 is 500 mg/kg/day under the condition employed in this study.

We studied effects of Samreungjeon water extract (SE) on the proliferation of transplanted-L1210 cells to mice. Samreungjeon is composed of Scirpi Tuber, Zedoariae Rhizoma, Aurantii immaturi Pericarpium, Pinelliae Tuber and Hordei Fructus Germinatus. When SE (500 mg/kg) was administered orally once a day for 7 days after transplantation of L1210 cells to mice, the proliferation of transplanted-L1210 cells was decreased and DNA fragmentation of transplanted-L1210 cells was induced. Also, DNA fragmentation of L1210 cells was enhanced by co-culture with the peritoneal macrophages obtained from SE-administered mice and was partly inhibited by L-NMMA in vitro. SE enhanced the production of nitric oxide from murine peritoneal macrophages in vitro and in vivo. These results suggest that SE partly induces apoptosis of transplanted-L1210 cells via production of nitric oxide from macrophages.

Cigarette is the risk factor of Lung cancer, chronic obstructive pulmonary disease and ischemic heart disease. So I have studied the effect of Macmoondongtang in rat exposed to cigarette smoke. Thirty-six healthy rat subjects were divided into 6 groups-the control group(sample I), the groups of administration of Platycodi Radix(sampleII), Adenophorae Radix(sampleIII), Liriopsis Tuber(sampleIV), Maximowicziae Fructus(sample V) and Macmoondongtang(sample VI), and expose to cigarette per day for 12 days. 1. On level of leckocyte are significant all the group of sampleII, sampleIII, sample IV, sample V, sample VI on 6th day and singificant the groups of sampleIV, sample V on 12th day. 2. On level of hemoglobin are singificant the groups of sample IV, sample V, sample VI, on 6th day, and significant sample II, sample III, sample IV, sample V, sample VI on 12th day. 3. On platelet level are significant all the group of sampleII, sample III, sample IV, sample V, sample VI on 12th day. 4. On SOD activity are significant all the groups of sample IV, sample VI, on 6th day, and significant sampleII, sample III, sample VI on 12th day. According to the results, Macmoondogtang is effective to risk of cigarette smoke.

Objectives : The purpose of this study is to determine the impurity tolerance of Zanthoxylum Peel. Methods : Compare with medicinal Herb Books and the Pharmacopoeia of 6 nations. Results : Current Pharmacopoeia show different Zanthoxylum Peel's Purity, such as 2.0% of seeds and fruit stalk, etc. in North Korea, 2% of seeds in Vietnam, totally 3% in China. On the other hand, Korea and Japan set the total number 26.0% including the specific numbers such as 20.0% of seeds, 5.0% of fruit stalk, 1.0% of the other foreign matter. This Zanthoxylum Peel's Purity, 26.0%, is too high compared to that of other medical matters specified by The Korean Pharmacopoeia Ninth Edition. When The Japanese Pharmacopoeia Sixth Edition firstly set the Zanthoxylum Peel's Purity, the herbal name was Fructus. However, since the part for medical usage in origin is well-ripen pericarp, not seed, the permissible level, 30.0%, is supposed to be simple error range, 3.0%. Conclusions : As a result, I think bills concerning the Zanthoxylum Peel's Purity should be revised to the total number 3.0% or specifically set the level 2.0% of seeds, 1.0% of fruit stalk, twig and so on.

Objectives : To evaluate the extraction efficiency of water decoction with or without non-woven fabric underlying comparison of the HPLC (high-performance liquid chromatography) profiles of the hesperidin which is the standard of Citri Pericarpium. Methods : Pyungwisan, which is comprised of Atractylodis Rhizoma, Magnoliae Cortex, Citri Pericarpium, Glycyrrhizae Radix, Zingiberis Rhizoma, and Ziziphy Fructus, was extracted in boiling water with non-woven fabric or without non-woven fabric. Then hesperidin content was analyzed by HPLC. Results : The contents of hesperidin in the water extract of Pyungwisan which was decocted without non-woven fabric showed $219.57{\pm}2.51\;mg/g$ and $138.90{\pm}6.32\;mg/g$ in with non-woven fabric decoction. Conclusions : These results suggest that herbal decoction without non-woven fabric might increase extraction efficiency.

Objectives The purpose of this study is to examine the meaning of the Soeumin's Watery diarrhea with little residue(下利淸水). Methods We examined the Watery diarrhea with little residue and Daeseunggi-tang(大承氣湯) in 『Sanghanlun(傷寒論)』, and considered the quotation and the treatment of the Watery diarrhea with little residue in 『Donguisusebowon(東醫壽世保元)』. Afterward, we considered the meaning of the Soeumin's Watery diarrhea with little residue by comparing the view of Junggyeong Jang and Jema Lee. Results and Conclusion 1. Jaricheongsu Saeksuncheong(自利淸水 色純靑) is an expression about the aspect of the Watery diarrhea in 『Sanghanlun』. Especially, Saeksuncheong(色純靑) means there is no residue in Watery diarrhea, and is an expression to distinguish from Haricheonggok(下利淸穀). 2. Haricheongsu(下利淸水) is the Watery diarrhea with little residue in 『Donguisusebowon』. It is caused by the coldness of the Soeumin and should be understood separately from Harihwangsu(下利黃水). 3. Considering the characteristics of the Soeumin, Jema Lee divided the aspects of the Watery diarrhea according to turbidity. Then, he suggested Gwangyebujaijung-tang(官桂附子理中湯) in the warm method(溫法), Seed of Crotonis Fructus(巴豆) in the diarrhea method(下法), and Gangchulgwanjung-tang(薑朮寬中湯) in the warm method after using the diarrhea method as the treatment of the Watery diarrhea with little residue, and aimed to treat the coldness of the Soeumin.

The Pharmacologic action of ethanol extracts and essential substance obtained from fruits of Evodia rutaecarpa are studied. 1) Motility of the isolated rabbit-intestine was decreased in proportion to the concentration of essential substance. 2) Intestinal contraction induced by acetylcholine 10? 6g/ml was inhibited by the essential substance $10^{-5}g/ml$. 3) Contractile responses of the isolated rabbit-intestine by serotonin $10^{-5}g/ml$ and histamine $10^{-5}g/ml$ were depressed significantly with the essential substance $10^{-5}g/ml$. 4) Alpha adrenergic receptor blocking effect of dihydroergotamine was interfered significantly with the essential substance. 5) Analgesic effect in mice by acetic acid stimulating method was observed significantly with both of the ethanol extracts and essential substance. 6) Blood pressure and respiration of the rabbits were not significantly influenced with the essential substance.
