The natural dyeing of silk fabric with Scutellaria baicalensis extract was investigated. The proper colorant concentration, dyeing temperature, dyeing time, and pH for the dyeing of silk fabric with Scutellaria baicalensis extract were 90% v/v, $90^{\circ}C$, 60 minutes and pH 3, respectively. In various mordanted methods, the K/S values of mordanted methods were higher than those of unmordanted methods. Light colorfastness and washing colorfastness of Fe mordanted silk fabric was improved by mordanting. The antibacterial properties of dyed and mordanted silk fabric showed a high reduction rate, and Scutellaria baicalensis extract was showed effective bacterial reduction.

The use possibility as a dyestuff of Scutellaria baicalensis was investigated. The optimum conditions were evaluated when silk fabrics were dyed by Scutellaria baicalensis extract. The colorants of Scutellaria baicalensis were extracted better in water than methanol. The optical dyeing concentration was 80%(v/v), dyeing temperature was $80^{\circ}C$, dyeing time was 60minites, dyeing repetition was 2 turns. A Post-mordant method showed higher K/S value than premordant one, especially post-Fe appeared the highest value and post-Cr was second. Surface color was all Y. The color fastness was very good at the second repetition of no mordanted silk fabrics, all mordant fabrics were not improved the colorfastness. The antibacterial activity showed at Staphylococcus aureus tested specimen that bacterial reduction rate was 99.7%.

This study was conducted to evaluate the control effect of fungicides on control of Gray mold, growth characteristics, and root yield in the cultivation of Scutellaria baicalensis after barley cropping. All fungicides treated had no effect on the growth and flowering rate of Scutellaria baicalensis. All seed disinfectants had no effect on the growth and flowering date of Scutellaria baicalensis Georg. The major seed disinfectants were Benomyl Wp, $20\%$, Captan Wp, $50\%$, Hymexazol Ec, $30\%$, Carboxin D, $37.5\%$. Dry root yield were increased largely with Benomyl Wp, $20\%$, seed disinfectant than the other seed disinfectants had no injury with standard dosage. On the other hand, all seed disinfectants had slight injury in the double dosage level for the Scutellaria baicalensis Georg.

Scutellaria baicalensis Georgi is one of the most important medicinal herbs in traditional chinese medicine. The object of this study was to determine the effects of water extracts of Scutellaria baicalensis (SB) and Scutellaria baicalensis metabolite (SBM) on the anxiolytic-like activities in the elevated plus-maze (EPM) test. The water extracts of SB (100, 200, or 400 mg/kg), and SBM (100 mg/kg) were orally administered to male SD rats for 3 day. All rats were subjected to behavioral tests for the anxiolytic activity at 3 days. (omitted)

Scutellaria Radix, the dried roots of Scutellaria baicalensis Georgi (Labiatae), has been used in oriental traditional medicine for treatment of fever urine disorder, diarrhea, inflammation. Present study was carried out for the gastroprotective effect of chrysin, baicalein, baicalin, wogonin from Scutellaria baicalensis. This reports evaluated antioxidant effect, antibacterial activity against Helicobacter pylori and HCI-ethanol-induced gastric lesion in rats and showed the significant effectiveness. It may be regarded that the antigastritic effects and antibacterial activity of baicalin, baicalein from Scutellaria baicalensis are originated from acid-neutralizing capacity, free radical scavenging effects and the antibacterial activity against Helicobacter pylori.

Microwaves are non-ionizing electromagnetic waves of frequency between 300MHz to 300GHz and positioned between the X-ray and infrared rays in the electromagnetic spectrum. In recent years, the use of microwave for extraction of ingredient from plant material has shown remarkable research interest and potential. Scutellaria radix has been used as a traditional medicine for a variety of diseases. It has been reported to exert beneficial health effects, such as anti-bacterial, antiviral, anti-inflammatory, and free-radical scavenging. Oxidative stress or the accumulation of reactive oxygen species (ROS) leads neuronal cellular death and dysfunction, and it contributes to neuronal degenerative disease such as Alzheimer's disease, Parkinson's disease and stroke. In this study, we aimed to compare the neuroprotective and antioxidant effect of Scutellaria radix extracted by different methods using hot-water extraction (SBE-DW) or microwave extraction (SBE-DW-MW). As a result, we first examined HPLC analysis of hot-water and microwave extracts of Scutellaria radix. The hot-water and microwave extracts of Scutellaria radix showed the discernible difference patterns of HPLC analysis. Microwave-water extracts of Scutellaria radix increased DPPH radical scavenging activity more than hot-water extraction. Microwave-water extracts of Scutellaria radix also showed neuroprotective effects and ROS inhibition against glutamate-induced oxidative stress in mouse hippocampal HT22 cells, but hot-water extraction not showed. In addition, the phosphorylation of MAPKs induced by glutamate insult was prevented by microwave-water extracts of Scutellaria radix. Thus, these results suggested that microwave extraction can be utilized for improving the extraction efficiency and biological activity of Scutellaria radix.

Sam-Hwang-Sa-Shim-Tang(SHSST), a traditional Chinese medicine, composed of Rhei rhizoma, Scutellaria radix, and Coptidis rhizoma were used in the several disease including hypertension, constipation, and hemorrhage. In the present study, we investigated the neuroprotective effects of SHSST and its ingredients on the ischemia/ reperfusion-induced brain injury was evaluated in the rat brain. Ischemia was induced by intraluminal occlusion of the right middle cerebral artery for 120 min and reperfusion was continued for 22 h. SHSST (450 mg/kg), Rhei rhii oma (100 mg/kg), Coptidis rhizoma (100 mg/kg), and Scutellaria radik (100 mg/kg) were orally administered twice, promptly prior to reperfusion and 2 h after the repefusion. Total infarction volume in the ipsilateral hemisphere of ischemia/ reperfusion rats was significantly lowed by the treatments of SHSST (39.2%) and Scutellaria radix (66.5%). However, Coptidis rhizoma did not show any significant effects on the total infarct volume. The inhibiting effect of Scutellaria radix on the total infarct volume was more potent than that of SHSST. In addition, Scutellaria radix significantly inhibited myeloperoxidase (MPO) activity, an index of neutrophil infiltration in ischemic brain tissue. However, there was marked mismatch between total infarct volume and MPO activity in the Scutellaria radix-treated rats. Our findings suggest that Scutellaria radix as an ingredient of SHSST plays a protective role in ischemia-induced brain injury by inhibiting neutrophil infiltration. The effects of Rhei rhizoma on transient brain ischemia-induced neuronal injury are under study.

Agrobacterium rhizogenes, a gram-negative soil bacterium, is one of the most widely studied among them. A, rhizogenes can transfer T-DNA, excised from Ri (root inducing)-plasmids from the bacterial to the plant cell. It is the causal agent of 'hairy root' diseases in plants, and has been used for the production of hairy root cultures from a multitude of species. Five different strains of Agrobacterium rhizogenes differed in their ability to induce Scutellaria baicalensis hairy roots and also showed varying effects on the growth in hairy root cultures. A. rhizogenes R 1000 is the most effective strain for the induction (57.3%) and growth (11.9 g $L^{-1}$) in hairy root of Scutellaria baicalensis. Our results demonstrate that use of suitable strains of A. rhizogenes may allow study of the regulation of flavone biosynthesis in hairy root cultures of Scutellaria baicalensis.
