This study is about the five species of the genus Thalictrum growing abundantly in South Korea. Dried roots of plants; T. aquilegifolium var. japonica, T. simplex var. affine, T. actaefolium, T. tuberiferum were compared by morphological observation and screening test on the ingredient extracted by methanol, ether etc.. The experiments by thin-layer chromatography was at tempted to find out the similarity and the difference among them. In conclusion, the author found that: 1) A special component similar to coumarin was found under UV-ray from T. actaefolium. 2) By thin-layer chromatography, they show the corresponding spot supposed to be that of berberine and magnoflorine according to the $T_{ABLE}\;IV$. Therefore it is worthwhile considering that Thalictrum species would be a substitution for Epimedium species used as a tonic. 3) Thalictrum species has resemblance of ingredient and chemotaxonomy gives more help to classify them than the morphology.

Helicobacter pylori (H. pylori) is the most important factor of gastric disease in clinical practice. Moreover, smoking, stress and a poor diet may be additive factors for gastric damage. With these factors, increasing infection of H. pylori triggers gastritis, gastric ulcers and gastric cancer. To develop a new protective agent, we are concerned with plant-derived extract. The extract of Coptis chinensis (C. chinensis) and its constituents were investigated to assess their protective activities against gastric damage. The C. chinensis extract showed a scavenging effect against 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and superoxide radicals, inhibition of H. pylori colonization and antiulcerogenic activities in rat. In particular, palmatine derived from C. chinensis was found to be the novel protective agent. It is better than the C. chinensis extract, berberine, a well-known constituent of C. chinensis. We suggest that palmatine from the root cortex of C. chinensis may be a good candidate for the development of new pharmaceuticals to prevent gastric disease.

The Coptis Rhizome is known for containing a number of isoquinoline type alkaloids. Berberine, coptisine and palmatine are the major constituents of alkaloids. The alkaloids were isolated and determined by forming complex from Coptis japonica (Ranunculaceae). 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 l,2-dichloroethane solution was measured at 625 nm. A calibration curve for the alkaloids isolated from Coptis Rhizome was linear over the concentration range of 0.2-0.3 mg/mι. The method proved to be rapid, simple and reliable for the isolation and the determination of the alkaloids in Coptis Rhizome.

Jaeumganghwa-tang (JGT) is a traditional herbal medicine used for chronic bronchitis and inflammatory diseases. The variation in the amount of bioactive components of JGT and its fermentation JGT with ten species of microorganism was investigated via high performance liquid chromatography coupled with diode array detection (HPLC-DAD). Simultaneous qualitative and quantitative analysis of eight bioactive compounds; 5- hydroxymethylfurfural (5-HMF), paeoniflorin, nodakenin, hesperidin, nodakenetin, palmatine, berberine and glycyrrhizin were achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard compounds. In the result, the paeoniflorin amount was 6.95 mg/g that as a main compound in JGT. The amount of nodakenetin was the highest in the fermented-JGT with Lactobacillus fermentum KFRI 145 ($0.47{\pm}0.01mg/g$), which was increased by 2,250% compared to that in non-fermented JGT ($0.02{\pm}0.00mg/g$). In the fermented JGT using Lactobacillus acidophilus KFRI 162, most components were increased than non-fermented JGT, except paeoniflorin and hesperidin.

Hwangryunhaedoktang (HHT) has been traditionally used as a preventive and therapeutic medicine to treat enervation and diverse chronic diseases. This study was designed to compare the antioxidant, anti-wrinkle and whitening effects of HHT extract and its fermented extract by Leuconostoc mesenteroides (FHHT). FHHT was prepared by inoculation of L. mesenteroides after the extraction procedure with 70% ethanol. HHT and FHHT was investigated via high-performance liquid chromatography (HPLC). Simultaneous qualitative analysis of two bioacitive components, berberine and palmatine. was achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard components. Cell viability test results indicated that both HHT and FHHT were non-toxic. In DPPH radical scavenging ability, $SC_{50}$ values of the FHHT was $68.85{\mu}g/mL$, which is more effective than HHT. Moreover, FHHT showed higher expression in production of procollagen type I than HHT. In nontoxic concentration range, FHHT showed strong melanin production inhibitory effect in ${\alpha}-melanocyte$ stimulating hormone (${\alpha}-MSH$)-stimulated B16F10 cell ($IC_{50}=9.82{\mu}g/mL$). These results suggested that fermented extracts of hwangryunhaedoktang had considerable potential as a cosmetics ingredient with an antioxidant and anti-wrinkle and whitening effects.

In this study, we investigated the antibacterial effect of 69 oriental medicinal herbs (OMHs) on Actinomyces viscocus, Streptococcus sobrinus, and two strains of Streptococcus mutans as oral bacteria. Methanol extracts of OMHs were used in the first antibacterial test, and then boiled water, ethanol, methanol, and ethyl acetate extracts of C. japonica, C. sappan, P. mume, and S. chinensis were used in the second test. Boiled water extract of C. japonica was shown to have the most superior effect on oral bacteria. The extract yield of boiled water extract of C. japonica was 22%, and the growth of oral bacteria was almost inhibited at over a 180 mg/ml concentration. Antibacterial effect compound analyzed by UPLC method was identified as berberine, and the content was 25.54%. In addition, the extract appeared to be stable at $121^{\circ}C$ for 15 min.

Substantial evidence suggests that behavioral and reinforcing effects of cocaine can be mediated by the mesolimbic dopaminergic system. It has been shown that repeated injections of cocaine produce increase in locomotor activity, expression of the immediate-early gene, c-fos in the nucleus accumbens (NAc), which was one of the main dopaminergic terminal areas. Herbal-acupuncture as a therapeutic intervention has been widely used for the treatment of many functional disorders such as drug abuse. Coptidis Rhizoma (CR) and its main component, berberine (BER) were selected as herbal medicine of herbal-acupuncture. Both medicines have been known to have the therapeutic effect on the central nervous system. In order to investigate the effects of CR and BER herbalacupuncture at shenmen (HT7) point (CR/H and BER/H) on the cocaine-induced behavioral sensitization, the influence of CR/H and BER/H on repeated cocaine-induced locomotor activity, the change of c-Fos expression in the brain by immunohistochemistry were examined. Male SD rats were given CR/H (0.4mg/kg) and BER/H (0.1mg/kg) 30 min before daily injections of cocaine hydrochloride (15mg/kg. i.p.) 10 days. After 3 days withdrawal, rats received a challenge injection of cocaine (15mg/kg, i.p.). Systemic challenge with cocaine produced much larger increased locomotor activity, accumbal Fos-like immunoreactivity in the NAc. Pretreatment with CR/H and BER/H significantly inhibited cocaine-induced locomotor activity, the change of c-Fos expression in the rats. Our data demonstrated that the inhibitory effects of cocaine-induced behavioral sensitization by CR/H and BER/H were closely associated with the reduction of presynaptic dopamine release in the NAc. These results suggest that CR/H and BER/H can be effectively applied to cocaine addiction.
