Six protoberberine alkaloids were isolated from the chloroform layer of the rhizome of Coptis japonica Makino (Ranunculaceae). The structures of the isolated compounds were determined to be 6-([1,3]dioxolo[4,5-g]isoquinoline-5-carbonyl)-2,3-dimethoxy-benzoic acid methyl ester (1), oxyberberine (2), 8-oxo-epiberberine (3), 8-oxocoptisine (4), berberine (5) and palmatine (6) by physicochemical and spectroscopic methods. The compound 3 (8-oxo-epiberberine) was first isolated from natural sources. The compounds were tested for cytotoxicity against five tumor cell lines in vitro by SRB method, and also tested for the MDR reversal activities. Compound 4 was of significant P-gp MDR inhibition activity with ED50 value $0.018\;{\mu}g/mL$ in MES-SA/DX5 cell and $0.0005\;{\mu}g/mL$ in HCT15 cell, respectively.

A study was carried out to investigate the possibility of acclimation of Coptis japonica Makino in Korea. Coptis japonica could be grown within 4 years as a medicinal crude drug if it is cultivated in the area of mountain facing north(300m above sea level) with 70% light interception and appropriate soil texture. It is to be noted that the propagation of the plant is more important than the yield of berberine because the berberine contents do not change in different conditions. The results were as follows; 1. The germination rates of the seeds by covering with the pine tree leaves were the highest and averaged 63%. 2. The germination rates of dry seeds were not affected in spite of low temperature and $GA_3$ treatment. 3. The germination rates of the seeds stored in moistured sand were averaged 85%, but in dry state, they were not germinated. 4. The number of leaves and fresh weight of Coptis japonica from the area of mountain facing north were increased significantly. 5. The growth and fresh weight of Coptis japonica were reduced in clay. 6. The best growth was obtained under 70% light interception. It is possible to intercrop between evergreen trees. 7. The foliage dressing did not affect the growth. 8. The number of leaves and fresh weight were increased from the 3rd year, and the average weight of rhizomes was 5.7g in 4th year. 9. The berberine contents of the rhizomes of Coptis japonica under various treatment conditions ranged from 9 to 10%. Coptidis Rhizoma from this study and from Korean market showed much higher berberine contents than those from Japanese market.

As part of our program to isolate bioactive compounds from korean natural sources, we have screened traditional medicinal plants to cytotoxity on human tumor cells. Of them, the MeOH extract from rhizome of Coptis japonica Makino was found to be active against five cultured human tumor cell lines. So, the MeOH extract was subjected to successive solvent partitioning to give n-hexane, chloroform and BuOH. The activity was concentrated into the chloroform extract. The extract was chromatographied on a silica gel column and resulted in the isolation 5 alkaloids. (omitted)

14종 한약재의 70% 에탄을 추출물의 Helicobacter pylori에 대한 항균활성은 황련 (Coptis japonica Makino)이 가장 뛰어 났으며, 소엽 (Perilla frutescens var. acuta KUDO), 소목 (Caesalpinia sappan L.) 및 형개 (Schizonepeta tenuifolia Briq.)의 경우에도 높은 항균활성을 나타내었다. 그러나 Helicobacter pylori의 위내 서식을 도와주는 것으로 알려진 urease 활성억제능은 연교 (Forsythiae Fructus)의 메탄올 (80%) 추출물에서 가장 높았으며, 소목 및 형개의 추출물도 높았다. 특히 연교의 경우 한약재 추출물을 넣지 않은 대조군과 비교하여 80% 이상의 활성이 억제되었다. 연교의 메탄올 추출물을 물, 에틸아세테이트 (ethyl acetate), 부탄을 순으로 분획하여 각 분획물에 대한 urease 활성억제능을 검색한 결과 에틸아세테이트 분획에서 92%의 urease 활성이 억제되었다.

Coptis rhizoma was extracted with methanol or hot water. Methanol extracts had higher berberine content than water extracts, whereas the contents of Ca, Mg, Zn and K were higher in the water extracts. Rats were fed on the purified diets rich in 0.12% cholesterol only or supplemented with 0.5% of each extracts for four weeks. The concentration of total serum cholesterol was significantly lower in the rats given the extracts, irrespective of the extractants. Although the concentration of serum HDL-cholesterol was comparable among the groups, the ratio of HDL-/total-cholesterol was higher in rats given the extracts. The concentration of serum free fatty acids and ketone body were significantly elevated in rats given the extracts. On the other hand, the extracts supplements significantly decreased the contents of liver cholesterol and triacylglycerol. The amount of fecal bile acids was markedly higher in rats given the extracts, especially in those given water extracts. The results show an effective hypocholesterolemic action of Coptis rhizoma and it seems that the lower concentration of serum and liver cholesterol is resulted from the increased fecal bile acids in rats.

The fungicidal activities of Coptis japonica (Makino) extracts and their active principles were determined against Botrytis cineria, Erysiphe graminis, Phytophthora infestans, Puccinia recondita, Pyricularia grisea, and Rhizoctonia solani using a whole plant method in vivo, and compared with natural fungicides. The responses varied according to the plant pathogen tested. At 2,000 mg/l, the chloroform and butanol fractions obtained from methanolic extracts of C. japonica exhibited strong/moderate fungicidal activities against B. cinerea, E. graminis, P. recondita, and Py. grisea. Two active constituents from the chloroform fractions and one active constituent from the butanol fractions were characterized as isoquinoline alkaloids, berberine chloride, palmatine iodide, and coptisine chloride, respectively, using spectral analysis. Berberine chloride had an apparent $LC_{50}$ value of approximately 190, 80, and 50 mg/l against B. cinerea, E. graminis, and P. recondita, respectively; coptisine chloride had an $LC_{50}$ value of 210,20, 180, and 290 mg/l against B. cinerea, E. graminis, P. recondita, and Py. grisea, respectively; and palmatine iodide had an $LC_{50}$ value of 160 mg/l against Py. grisea. The isoquinoline alkaloids were also found to be more potent than the natural fungicides, curcumin and emodin. Therefore, these compounds isolated from C. japonica may be useful leads for the development of new types of natural fungicides for controlling B. cinerea, E. graminis, P. recondita, and Py. grisea in crops.

Coptis japonica Makino (황련, 48.5%), Lonicera japonica Thunb (금은화, 48.5%), Morus alba L. (상엽, 3%)를 혼합한 복합 한약재의 급여가 생산된 계란의 냉장 저장 중 일반 성분 및 물리적 특성에 미치는 영향을 조사하였다. 28주령의 Lohmann Brown 108수를 3가지 처리(복합 한약재 0, 0.3 및 1%), 6반복으로 완전 임의 배치한 후 6주간 급여하고 생산된 계란을 수거하여 $4^{\circ}C$ 냉장 저장하면서 일반 성분, 색도 및 조직감 등을 관찰하였다. 복합 한약재를 급여하여 생산된 계란은 수분, 단백질, 지방 및 무기물의 함량 차이가 없었으며 삶은 계란에서 3일차 적색도($a^*$-value) 및 황색도($b^*$-value)를 제외하고는 처리간 색도의 차이가 없었다. 그러나 저장 기간동안 처리구와 상관없이 적색도와 황색도가 증가하였다. 전체적인 조직감 측정에서도 복합 한약재 급여 처리는 14일차 탄성(springness)을 제외하고는 차이가 나타나지 않았다. 다만 계란의 저장기간에 따른 조직감의 차이는 보여 탄성과 검성(gumminess)는 저장기간이 늘어나면서 감소하는 것으로 나타났다. 결과적으로 복합 한약재의 급여는 생산된 계란의 일반 성분이나 색도, 조직감 특성에서 대조구와 큰 차이가 없는 것으로 판단되며, 이는 합성 항생제를 대체를 위한 복합 한약재의 첨가를 산업적으로 적용할 때 계란의 물리화학적 품질에 큰 영향이 없을 것으로 사료된다.

Periodontitis is an inflammatory disorder of the periodontium and is characterized by destruction of the tooth supporting tissues, mediated by the upregulation of synthesis and release of a variety of pro-inflammatory factors. Inflammatory cytokines and prostaglandins upregulate RANKL and its subsequent binding to RANK stimulates osteoclast formation, resorption activity, and survival. In our present study, we investigated the effects of HP08-0111, composed of Coptis japonica (Thunb.) Makino, vitamin C and vitamin E, upon inflammatory responses, osteoclastogenesis and alveolar bone loss. HP08-0111 decreased the expression of IL-1$\beta$ and COX2 on LPS-induced RAW 264.7 cells and inhibited osteoclast-specific genes such as c-Fos, MMP-9, and TRAP. HP08-0111 also exhibited protective effects against alveolar bone loss in rats with ligature-induced periodontitis. Our results suggest that HP08-0111 is potentially an important therapeutic tool for the treatment of disorders associated with bone loss such as periodontitis.
