Objectives : This study was conducted to evaluate the antioxidative and fibrinolytic activity of the water and ethanol extracts from medicinal plants. Methods : Five kinds of medicinal plants(Carthami Flos, Glycyrrhizae Radix, Schisandrae Fructus, Atractylodes Rhizoma, Shiitake mushiroom) were extracted with distilled water and 70% ethanol, and the extracts were tested for their antioxidative and fibrilytic activities. Results : The highest polyphenol contents of the water and ethanol extracts from medicinal plants were 812.52 mg and 685.44 mg per 100 g of Carthamus tinctorius and Schizandra chinensis, respectively. The electron donating abilities (EDA) of the water extracts from all medicinal plants except Lentinus edodes were about 90% at 1,000 ppm and ethanol extracts were higher than those of water extracts. The highest SOD-like activity and nitrite scavenging abilities (NSA) were both of water and ethanol extracts from Schizandra chinensis. Five kinds of medicinal plants had fibrinolytoc activity and the highest activities were water and ethanol extracts from Glycyrrhiza uralensis. Conclusion : These results suggest that the medicinal plants can be used as natural antioxidant to prevent oxidative damage in normal cells probably because of their antioxidative and fibrinolytic activities.

During the past two decades, China has seen her great progress in plant biotechnology. Since the Chinese market of herb medicine is huge, while the plant resources are shrinking, particular emphasis has been placed in plant tissue and cell cultures of medicinal plants, this includes fast propagation, protoplast isolation and regeneration, cell suspension cultures and large scale fermentation. To optimize culture conditions for producing secondary compounds in vitro, various media, additives and elicitors have been tested. Successful examples of large scale culture for the secondary metabolite biosynthesis are quite limited : Lithospermum ery throrhizon and Arnebia euchroma for shikonin derivatives, Panax ginseng, P. notoginseng, P. quinquefolium for saponins, and a few other medicinal plants. Recent development of genetic transformation systems of plant cells offered a new approach to in vitro production of secondary compounds. Hairy root induction and cultures, by using Ri-plasmid, have been reported from a number of medicinal plant species, such as Artemisia annua that produces little artemisinin in normal cultured cells, and from Glycyrrhiza uralensis. In the coming five years, Chinese scientists will continue their work on large scale cell cultures of a few of selected plant species, including Taxus spp. and A. annua, for the production of secondary metabolites with medicinal interests, one or two groups of scientists will be engaged in molecular cloning of the key enzymes in plant secondary metabolism.

Objectives : The purpose of this study was to investigate the interpretation of the Soyo-san(SYS) prescription in order to obtain the evidence for clinical applications. Methods and Result : We interpreted on the SYS-related contents based on 25 classic books, analyzed it according to followed categories ; meaning of name, alteration of herbal composition according to age, usage, origin, physiological and pathological situation of SYS, description of each herbal drug Conclusion : 1. So(逍) mean diminish(消), 遙 mean roll(搖). It reflected feature of SYS, that alleviate depression without impairing vital energy(正氣). 2. SYS was first mentioned in the prescription of peaceful benevolent dispensary(太平惠民和劑局方), its essential application was harminizing liver depression and spleen deficiency(肝鬱脾虛) 3. SYS originated from Sayuk-san. Sayuk-san was appropriate for soothe the liver and regulate the spleen(疏肝理脾), while SYS was suitable for depressed liver and blood deficiency(肝鬱血虛) 4. Most medical literature insisted that application situation of SYS is blood deficiency(血虛), depressed liver(肝鬱), spleen deficiency(脾虛). And there is strong correlation between three factors. 5. Bupleurum falcatum L.(柴胡), Mentha arvensis L.(薄荷) alleviates liver depression as "pungent dissipate-qi uprais (辛散氣升)" nature. Angelica gigas Nakai(當歸), Paeonia lactiflora Pall.(白芍藥) emoliates the liver by nourishing the blood. Atractylodes japonica Koidz. ex Kitam.(白朮), Poria cocos(茯苓), Glycyrrhiza uralensis Fisch.(甘草), Zingiber officinale Roscoe(生薑) cultivate the basis as tonifying earth(補土).

Glycyrrhiza uralensis (or licorice) is a widely used Oriental herbal medicine from which the phenylflavonoids dehydroglyasperin C (DGC), dehydroglyasperin D (DGD), and isoangustone A (IsoA) are derived. The purpose of the present study was to evaluate the antioxidant properties of DGC, DGD, and IsoA. The three compounds showed strong ferric reducing activities and effectively scavenged DPPH, $ABTS^+$, and singlet oxygen radicals. Among the three compounds tested, DGC showed the highest free radical scavenging capacity in human hepatoma HepG2 cells as assessed by oxidant-sensitive fluorescent dyes dichlorofluorescein diacetate and dihydroethidium bromide. In addition, all three compounds effectively suppressed lipid peroxidation in rat tissues as well as $H_2O_2$-induced ROS production in hepatoma cells. This study demonstrates that among the three phenylflavonoids isolated from licorice, DGC possesses the most potent antioxidant activity, suggesting it has protective effects against chronic diseases caused by reactive oxygen species as well as potential as an antioxidant food additive.

Herbal mixture water extract of (Phellodendron amurense, Scuellaria baiklensis, Spphora flavescens, Lithospermum erythrorhizon, Mellaphis chinesis, Alumite, Zanthoxylum schinifolium, Glycyrrhiza uralensis), which exhibit several beneficial effects including acne and skin diseases, was tested for anti-microbial activity and anti-inflammation effects. The herbal mixture extract showed antimicrobial activity against Stapylococcus epidermis, Propionibacterium acne, and Malassezia furfur. The growth of Stapylococcus epidermis, Propionibacterium acne, and Malassezia furfur was inhibited allergy and LPS induced cyclooxygenase-2(COX-2)gene expression in RAW24.7macrophage. The results indicated th ear swelling and histamine release induced by compound 48/80 were dose-dependently reduced, ranging 11-38% and 11-56%, respectively. Furthermore the extract inhibited the expression of LPS-induced COX-2 proteins and mRNAs without an appreciable cytotoxic effects on RAW264.7 cells. The cytotoxicity of the extract using M7T assay showed the cytotoxicity of 7 and 18% against L929 cell line. Based on these results, it is concluded that the herbal mixture water extract can be applied to the acne and skin diseases therapy.
