PURPOSE: This study was conducted to evaluate the physicochemical properties of different batches of Saururus chinensis using different roasting temperature that were dried at different using different roasting temperatures and their were determined the antioxidative activities of water and 70% ethanol extracts. METHODS: Extracts were examined for the total phenolic acid content, the and flavonoids contents and the antioxidant properties, including DPPH radical scavenging activity, ABTs scavenging activity and, the reducing power. RESULTS: Moisture content was significantly higher in the LSC and the crude ash content was significantly higher in the HSC. The crude protein content was higher in the LSC (although not significantly), and the crude fat and carbohydrate contents were higher in the HSC (although not significantly). The total phenolic content was lower in the samples extracted with water, but there was no significant difference. However, the extracts extracted with 70% ethanol at a high drying temperature were significantly higher. The low temperature and high drying temperature batches of Saururus chinensis were significantly higher in the samples extracted with 70% ethanol than those extracted with 70% ethanol. The total phenolic acid content, the total flavonoid content and the electron donating ability were highest in the ethanol extract of Saururuschinensis treated at a high temperature. However, the ABTs radical activity was highest in the water extracted, high-temperature treated Saururuschinensis. The 70% ethanol extract of high temperature roasted Saururuschinensis had the highest antioxidative activities of all the Saururuschinensis batches. CONCLUSION: The total phenolic acid contents, total flavonoid contents, electron donating activity and reducing power activity were highest in all the 70% ethanol extraction batches of the high-temperature treated samples.

Exfoliative dermatitis is caused by various etiologic factors including preceding dermatosis, drug-use, malignancy-related reasons and idiopathies. We present an exfoliative dermatitis caused by topical application of the herbal extract, Saururus chinesis baill. Saururus chinesis bail has been used traditionally as a folk remedy for various kinds of dermatoses in Korea. Therefore, the public should be warned of indiscreetly-used, natural, but not purified, herbal products.

Saururus chinensis Baill was reported to inhibit alpha-glucosidase in vitro and flatten postprandial increase in blood glucose in streptozotocin (STZ)-induced diabetic rats. We studied the effect of chronic consumption of S. chinensis Baill on blood glucose and lipid profile in STZ-induced diabetic male rats fed high fat diet. Male rats weighing 100-120 g were fed 30% fat diet with and without 10% freeze-dried leaves of S. chinensis Baill for 7 weeks after 1 week of adaptation. The rats were rendered diabetic by intravenous injection of STZ (60 mg/kg) after 6-week feeding of the assigned diets. At 1 week after the injection, the rats were sacrificed after an overnight fast. Plasma glucose (380.2 +/- 14.4 mg/dL), total cholesterol (93.9 +/- 7.9 mg/dL) and triglyceride levels (123.6 +/- 7.5 mg/dL) of the S. chinensis Baill group were significantly lower than those of the control group (418.1 +/- 12.0 mg/dL, 119.9 +/- 9.4 mg/dL, 152.0 +/- 10.3 mg/dL, respectively, p<0.05). Chronic consumption of S. chinesis Baill significantly decreased maltase activity of the small intestinal mucosa (120.1 +/- 8.7 U/g protein) compared with the control group (96.8 +/- 7.0 U/g protein, p<0.05). These results suggest that S. chinensis Baill have hypoglycemic and hypolipidemic effects by inhibiting alpha-glucosidase activity in the animal model of diabetes mellitus.

This study investigated the preventive effect of Saururus chinensis Baill against renal damage induced by a high-fructose diet in rats. The rats (n = 30) were fed either a cornstarch-based (65%), high-fructose (65%), or high-fructose (64.5%) diet with 0.5% S. chinensis Baill extract for 10 weeks. Twenty-four hour urine collections were obtained and the animals were sacrificed after an overnight fast. Serum urea and creatinine and urine albumin were measured using colorimetric methods, and creatinine clearance was determined. In addition, thiobarbituric acid reactive substances (TBARS), reduced glutathione (GSH), and the activity of superoxide dismutase (SOD) in the kidney were determined. Kidney samples were also examined histologically. The fructose-fed rats showed renal dysfunction, indicated by decreased creatinine clearance, increased albumin in the urine, and increased urea and creatinine in the serum. These renal function parameters were comparable to control levels in rats that consumed S. chinensis Baill. Fructose consumption increased renal TBARS and reduced GSH and SOD activity, whereas these levels were near-normal in the rats consuming S. chinensis Baill. The kidneys of fructose-fed rats showed glomerular basement membrane thickening, mesangial matrix expansion, and tubule dilation. These pathological changes were not seen in the rats that consumed S. chinensis Baill. Therefore, S. chinensis Baill effectively alleviated fructose-induced renal damage in these rats, at least partially due to antioxidant activity.

To investigate the chlorogenic acids resources in Eucommia ulmoides Olive leaves, Lonicera japonica Thunb. leaves and Houttuynla cordata Thunb. leaves, methanolic extracts of these three materials have been analysed qualitatively for chlorogenic acids and their derivatives by structure-diagnostic LC-MSn. Three monocaffeoylquinic acids (3-CQA, 4-CQA, 5-CQA) were detected. 5-CQA dominated this subgroup in Eucommia ulmoides Olive and Lonicera japonica Thunb. leaves, but 3-CQA and 4-CQA dominated this subgroup of chlorogenic acids in the leaves of Houttuynla cordata Thunb. Caffeoylquinic acid-glycosides were detected for the first time from Eucommia ulmoides leaves. 5-FQA was found in Lonicera japonica Thunb. leaves, and 3-FQA and 4-pCoQA have been identified in Houttuynla cordata Thunb. This is the first report of the chlorogenic acid profile in Houttuynla cordata Thunb. The comparatively unusual profile of caffeoylquinic acids in Houttuynla cordata Thunb. makes it a convenient source of 3-CQA and 4-CQA that are not commercially available.

OBJECTIVETo construct the fast propagation system of Houttuynia cordata Thunb. new line by selecting the proper type and concentration of plant growth regulators and proper explants.

METHODThe different explants of Houttuynia cordata new line were cultured on MS media with different concentration of different plant grow regulators.

RESULTStem node over-ground and shoot tip were optimum explants for fast propagation. The stem which node grew on MS medium with KT at 0.5 mg x L(-1) could induce more leaves and grow higher. The shoot tip cultured on MS medium with 1.0 mg x L(-1) 6-BA could induce better callus. Adventitious shoots were better achieved from over-ground nodal explants cultured on MS medium supplemented with 6-BA at 1.0 mg x L(-1) and NAA at 0.2 mg x L(-1), or 6-BA at 0.5 mg x L(-1) and NAA at 0.2 mg x L(-1). MS medium with IAA at 0.2 mg x L(-1) was the best one on inducing roots.

CONCLUSIONThe propagat coefficient can be highly improved by inducing adventitious shoots through stem node over-ground, and thus plentiful seeds for production can be provided.

OBJECTIVETo seek effective drugs inhibiting herpes simplex virus (HSV-2) with the signal pathway required by virus replication as the target spot.

METHODHSV-2-induced Vero cytopathic effect was observed, and MTT method was adopted to detect call activity, in order to assess the antiviral capacity of freeze dried powder of aqueous extracts of Saururus chinensis (AESC). Western blot was used to check the effect of AESC on signal pathway induced by HSV-2 virus in HeLa cells.

RESULTAESC obviously inhibits the pathway activation of CPE induced by HSV-2 infection and NF-kappaB required for virus replication. The inhibition ratio of AESC freeze dried powder at 0.10, 0.03, 0.01 and 0.003 g x L(-1) were (70.68 +/- 3.39)%, (61.74 +/- 2.13)%, (39.31 +/- 1.10)% and (18.54 +/- 3.44)%, respectively. The IC50 was determined at (0.023 +/- 0.004) g x L(-1). The inhibition concentration of the positive control acyclovir was 0.001 g x L(-1) (5.0 x 10(-6) mol x L(-1)). The best administration time was from 2 h before infection to 6 h after infection. Western blot also showed that AESC can notably inhibit HSV-2-induced NF-kappaB nuclear transfer.

CONCLUSIONAESC can inhibit HSV-2 virus replication, which is related to the pathway activation of NF-kappaB required for virus replication.
