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.

Methanol extract (1.0 wt%) of Scutellaria baicalensis George satisfied preservation standard of CTFA (The Cosmetics, Toiletry, and Fragrance Association) against Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans and Escherichia coli which were inoculated in skin lotion. Even at a low concentration (0.01 wt%) the extract showed high superoxide dismutase-like activity. The CTFA standard could also be satisfied for the above four strains when methanol extract of Liriope platyphylla were combined with the 1.0 wt% extract of S. baicalensis George. This result suggests that extract of L. platyphylla does not hinder the preservation activity of S. baicalensis George. Moreover, skin moisture content could be maintained for 6 hours after the application of a cream containing the extract of L. platyphylla.

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.

본 실험은 황금열수추출물이 알레르기성 접촉 피부염 유발 시 항산화활성, serum Ig E농도와 표피회복능에 미치는 영향을 조사하기 위해 행해진 것으로 1-chloro-2,4-dinitrochlorobenzene(DNCB: 2.5% DNCB 1 mL로 감작, 4일 경과 후 1% DNCB 1 mL로 유발) 처리로 알레르기성 접촉 피부염이 유발된 Sprague Dawley rat 수컷 흰쥐에 황금열수추출물(1 mL/kg/day)을 경구투여한 다음 혈장과 간의 항산화활성, 혈중 Ig E 농도, 표피두께변화를 관찰하였다. DNCB 처리에 의해 지질과산화물 함량과 Ig E 농도, 표피두께가 증가하였으며 황금열수추출물의 경구투여에 의해 간의 지질과산화물 함량 감소, 혈중 Ig E 농도 감소, 표피두께가 저하되는 결과를 보였다. 이상의 결과로 미루어 황금열수추출물이 알레르기성 접촉피부염으로 유발된 rat의 체내 항산화활성과 Ig E 농도개선, 표피두께 개선에 효과가 있는 것으로 생각된다.

The concentrations of L-ascorbic acid (AsA, ascorbate, vitamin C) and its biosynthetic and metabolically-related enzymes such as L-galactono-1,4-lactone dehydrogenase (GLDase), ascorbate peroxidase (APX), and ascorbate oxidase (ASO) were investigated in suspension cultures of Scutellaria baicalensis. Cells growing from 4 days after subculture (DAS) to 9 DAS and from 16 DAS to 19 DAS showed a diauxic growth, and then growth rapidly decreased with further culturing. The AsA content slowly increased to 19 DAS, reached a maximum at 21 DAS (ca $120\;{\mu}g/g$ dry cell wt), and then rapidly decreased with further culturing. GLDase and ASO activity were well correlated with the cell growth curve, showing a maximum at 19 DAS, whereas APX activity showed a good correlation with the changes in AsA content, showing a maximum at 21 DAS. The total ascorbate contents (reduced form, AsA, and oxidized form, dehydroascorbate, DHA) were markedly enhanced at 10 DAS when L-galactose and L-galactono-1,4-lactone (25 mM) were added to SH medium supplemented with 20 g/l sucrose at 9 DAS, by 5.5 and 6.8 times, respectively. DHA composed more than 90% of the total ascorbate contents in suspension cultures of S. baicalensis, even though the ratio of reduced to oxidized form slightly varied with cell growth stage. The results indicate that L-galactose and L-galactono-1,4-lactone are effective precursors of AsA in cell cultures of S. baicalensis, and that in vitro cultured cells provide suitable biomaterials for the study of biosynthesis and metabolism of AsA.

Various mixtures were prepared depending on the mixing ratio of Scutellaria baicalensis hot water extract (SB-HW) and Chrysanthemum morifolium ethanol extract (CM-E) and their anti-inflammatory activity were compared. Among them, SB-HW (80 ㎍/mL)/CM-E (120 ㎍/mL) or SB-HW (40 ㎍/mL)/CM-E (160 ㎍/mL) significantly inhibited LPS-stimulated NO and IL-6 levels in RAW 264.7 cells. The SB-HW (80 ㎍/mL)/CM-E (120 ㎍/mL) mixture, which was determined as active mixture, significantly reduced MUC5AC secretion in PMA and LPS-induced NCI-H292 cells. The active mixture also reduced the production of PGE2 and IL-8 in PMA-induced A549 cells. LC-MS/MS analysis showed that the active mixture was composed of high contents of flavone glycosides, such as baicalin and cynaroside. Western blot analysis indicated that the active mixture suppressed phosphorylation of ERK, JNK, and p38, associating with the inhibition of MAPK signaling. Taken together, our results suggest that the active mixture could be applied as a new anti-inflammatory herbal medicine

Scutellaria baicalensis (SB), a traditional herb with high pharmacological value, contains more than 10% flavone by weight. To improve the biological activity of flavones in SB, we aimed to enhance the bioconversion of baicalin (BG) to baicalein (B) and wogonoside (WG) to wogonin (W) in SB during fermentation using beta-glucuronidase produced from Lactobacillus brevis RO1. After activation, L. brevis RO1 was cultured in milk containing SB root extract with various carbon or nitrogen sources at $37^{\circ}C$ for 72 h. During fermentation, the growth patterns of L. brevis RO1 and changes in the flavone content were assessed using thin-layer chromatography and high-performance liquid chromatography. After 72 h of fermentation, the concentrations of B and W in the control group increased by only 0.15 and 0.12 mM, respectively, whereas they increased by 0.57 and 0.24 mM in the fish peptone group. The production of B and W was enhanced by the addition of 0.4% fish peptone, which not only improved the growth of L. brevis RO1 (p < 0.001) but also enhanced the bioconversion of flavones. In conclusion, the bioconversion of flavones in SB may provide a potential application for the enhancement of the functional components in SB.

Scutellaria baicalensis Georgi (SJ) is a perennial plant and its root has been used in oriental traditional medicine for treatment of fever, inflammation, diarrhea and anticancer effect, etc. In this study, plant tissue culture system for SJ was developed. Stem piece of younger plant was optimum explant for callus induction and growth on MS medium supplemented with NAA 1.0 ㎎/L plus BA 0.5 ㎎/L. Plantlet regeneration through callus culture was well on MS medium containing NAA 1.0 mg/L. SJ has been known biologically active substances such as baicalin, baiclein, and wogonin. This study was carried out to examine the effect of plant growth regulators for production of baicalin, baicalein, and wogonin through callus culture. The HPLC pattern of callus extract was identical to that of standard solution, it shows that the callus produced by tissue culture has the same flavonoids composition of SJ. Baicalin, baicalein, and wogonin production was 471.5~52.8 ㎍/g, 137.6~4.0 ㎍/g, and 16.6~1.3 ㎍/g, respectively, on MS media with nine different plant growth regulator combinations. This may indicate that plant tissue culture of SJ possible to produce the biologically active substances effectively

Roots of Scutellaria baicalensis have been used for fever remedy; diuresis, antiphlogistic. For the investigation of the active component from aerial parts of Scutellaria baicalensis, MeOH extracts from aerial parts of Scutellaria baicalensis were suspended with $H_2O$, and partitioned by $CHCl_3$. In order to investigate the efficacy of antioxidative activity the activity guided fraction and isolation of physiologically active substance were peformed. Its $H_2O,\;30\%,\;60\%$ MeOH and MeOH fractions were examined on antioxidative activity using DPPH method and TBARS assay; It was revealed that $30\%\;and\;60\%$ MeOH fractions have significant anti-oxidative activity. its fractions testing type I allergy, compound 48/80 induced systemic anaphylaxis was applied. As a result, compared with reference (cromolygate), these fraction significantly inhibited systemic anaphylaxis by $71\%\;and\;57\%$, respectively. From $30\%,\;60\%$ MeOH fraction, five compounds were isolated and elucidated apigenin 6-C-${\alpha}$-L-arabinopyranosyl-8-C-${\beta}$-D-glucopyranoside (isoschaftside, I), scutellarein 7-O-${\beta}$-D-glucuronopyranoside (scutellarin, II), apigenin 7-O- ${\beta}$-D-glucuronopyranoside (III), isoscutellarein 8-O-${\beta}$-D-glucuronopyranoside (IV), kaempferol 3-O-${\beta}$-D-glucopyranoside (V) through their physicochemical data and spectroscopic methods. We measured radical scavenging activity with DPPH method and anti-lipid peroxidative efficacy on human LDL with TBARS assay. [$I] showed antioxidant activities in order. Type I allergy compound 48/80 induced systemic anaphylaxis was applied. $[V inhibited systemic anaphylaxis in order.
