Gastritis and gastric ulcer were known to be induced by gastic acid, stress, ethanol, Helicobacter pylori and free radical, etc. This study was performed for the development of a new drug or nutraceutical from medicinal plants or natural products with anti-gastritis, anti-ulcerative and gastroprotective activities. The water extract of Scutellaria baicalensis was exhibited potent inhibition in HCl ethanol-induced gastric lesion, acetic acid-induced and Shay ulcers, indicating the effects on gastric lesion and ulcer in rats. The water extract of Scutellaria baicalensis significantly inhibited HCl ethanol-induced gastric lesions at the oral dose of 300, 500 mg/kg. In pylorus ligated rats, the treatments of the water extract from Scutellaria baicalensis showed decrease in the volume of gastric secretion and acid output and increase pH at oral dose of 300, 500 mg/kg. And significantly reduced acetic acid-induced ulcer at the oral dose of 500 mg/kg for 12 days. In this study, we have found that the water extract from Scutellaria baicalensis had significant improvement in acute gastritis and ulcer at the dose of 300, 500 mg/kg and in chronic gastritis and ulcer at the dose of 500 mg/kg. Also we evaluated the antibacterial activity against Helicobacter pylori treated with Scutellaria baicalensis. Scutellaria baicalensis had a equivalent antibacterial activity with ampicilin against H. pylori at the dose of $100\;{\mu}/ml$. In histological examination, the water extract of Scutellaria baicalensis drastically restored gastric damages induced by HCl ethanol solution, pylorus- ligature and acetic acid. Therefore, we may use the water extract from Scutellaria baicalensis as antigastritic and antiulcerative agent for the purpose of the improvement or treatment of gastritis and gastric ulcer.

Objectives The purpose of this study is to confirm the effect of alleviating inflammation through creating skin fat barrier from Scutellaria baicalensis extract. Methods Four-week-old Balb/C mice were divided into four groups: control group (Ctrl), lipid barrier eliminated group (LBEG), dexamethasone (DM) treated group after lipid barrier elimination (DMTG), and Scutellaria baicalensis (SB) treated group after lipid barrier elimination (SBTG). Scutellaria baicalensis extract were administered for 5 days after removal of the fat barrier. Changes in skin condition, improvement of the fat barrier, and relief of inflammation were observed in each group. Results Compared to LBEG and DMTG, pathological skin damage and tissue changes were less in SBTG, and transepidermal water loss (TEWL) and pH were also significantly reduced. Filaggrin was also significantly increased in SBTG. KLK7, PAR-2, and TSLP in SBTG also showed significant reduction compared to the LBEG and DMTG. Conclusions Scutellaria baicalensis extract restores skin barrier and relieves inflammation through the creation of skin fat barrier. This means that the Scutellaria baicalensis extract can regulate Th2 differentiation through the creation of the epithelial fat barrier.

Scutellaria baicalensis $G_{EORGI}$ (Scutellariae Radix) has been used to clear heat and to dry dampness in the stomach or intestines, which manifests as diarrhea or dysenteric disorder. In this study, we investigated the effective preparation of active components in Scutellariae Radix using the methods of solvent extraction and absorption fractionation for the development of new functional food or pharmaceuticals. The marker substances, baicalin, baicalein, wogonoside, and wogonin were directly isolated from the Scutellariae Radix. There chemical structures were elucidated by spectroscopic analysis. The Scutellariae Radix was extracted with hot water. To enhance yield of flavonoids in Scutellariae Radix, the hot water extract was dissolved in ethanol with concentration dependent manner. The precipitates were separated using centrifugal techniques at 10,000 rpm. Supernatant liquid was applied to the HPLC for quantification of major compounds. Separately, the hot water extract was absorbed on Diaion HP-20 resin. And then, the absorbed fraction was eluted with methanol for HPLC. The contents of baicalin, baicalein, wogonoside and wogonin in different treatment methods were analyzed by HPLC. Total amount of four major components were 16.9% in 50% ethanol extract, 21.7% in 70% ethanol extract, 20.5% in 90% ethanol extract, and 39.3% in absorbed fraction of Diaion HP-20 resin. In these results, we found that resin absorption method is suitable for the extraction of enriched flavonoids from Scutellariae Radix.

Scutellaria baicalensis water extract (SWE)는 지질 다당류 LPS로 유도된 RAW 264.7 세포에서 NO 및 전 염증성 사이토카인인 TNF-α의 생성을 세포 독성을 유발하지 않고 유의하게 억제하였다. 또한, SWE는 iNOS 및 COX-2의 단백질발현을 농도의존적으로 감소시켰으며, ERK, JNK, p38과 같은 MAPKs 계열의 인산화 발현 수준을 조사한 결과 JNK와 p38의 발현 수준을 감소시켰다. 이는 SWE가 p38 인산화를 억제함으로써 iNOS, COX, 그리고 TNF-α와 같은 전 염증성 사이토카인의 발현을 감소시키며 결론적으로 NO의 생성을 억제시킨다는 결과를 도출할 수 있었다. 본 연구는 항염증 효능 검증뿐 아니라 염증대사기전의 주요인자를 탐색함으로써 황금의 기능성 소재로써의 가능성을 시사한다.
