In this study, we compared the anti-inflammatory activity of Pinus koraiensis cone bark extracts prepared by conventional extraction and microwave-assisted extraction (MAE). Water extracts and 50% ethanol extracts prepared using MAE were applied to RAW 264.7 cell at 5, 10, 25, and 50 μg/mL of concentrations, and tested for cytoxicity. The group treated with 50 μg/mL of 50% ethanol extracts show...

Phycobiliprotein-containing water and carotenoid-containing methanolic extracts of three different cyanobacteria, Pseudanabaena sp., Spirulina sp. and Lyngbya sp., were studied for their DPPH scavenging, iso-bolographic studies, and anti-nephrolithe activities. The best EC50 values for DPPH scavenging were in Lyngbya water (LW, 18.78 ± 1.57 mg·mg(-1) DPPH) and Lyngbya methanol (LM, 59.56 ± 37.3...

Phytochemical screening of solvent extracts from Callilepis laureola plant was studied. Methanol and water extracts, respectively, revealed that phytochemical constituents found in both extracts were phenolics and gums. Reducing sugars were only observed in water extract while phytosterols and flavanoids were only found in methanol extract. Other phytochemical constituents such as saponins, gly...

Yam (Dioscorea batatas) is widely consumed as functional food for health promotion mainly in East Asia countries. We assessed whether yam root (tuber) or bark (peel) extracts stimulated the activity of osteoblasts for osteogenesis. MC3T3-E1 cells (mouse osteoblasts) were treated with yam root extracts (water or methanol) (study I) or bark extracts (water or hexane) (study II) within 0~10 μg/mL ...

Boreal hardwood species, including Japanese white birch (Betula platyphylla Sukat. var. japonica Hara), Japanese chestnut (Castanea crenata Sieb. et Zucc.), katsura tree (Cercidiphyllum japonicum Sieb. et Zucc.), Siebold's beech (Fagus crenata Blume), mulberry (Morus bombycis Koidz.), and Japanese rowan (Sorbus commixta Hedl.), had xylem parenchyma cells (XPCs) that adapt to subfreezing tempera...

This study investigated the antioxidant activity of methanol (MeOH) and water extracts from roots of Cirsium japonicumin vitro. MeOH extract showed a stronger free radical scavenging activity than water extract. However, both of extracts showed a concentration dependent hydroxyl radical scavenging activity, reducing power and metal chelating ability. MeOH extract had greater phenolic and flavon...

BACKGROUND/OBJECTIVES The present study was conducted to examine the inhibitory effect of loquat leaves on MDA-MB-231 cell proliferation and invasion. MATERIALS/METHODS Female athymic nude mice were given a subcutaneous (s.c.) inoculation of MDA-MB-231 cells and randomly grouped to receive a s.c. injection of either 500 mg/kg ethanol, water extract or vehicle five times a week. Tumor growth, ...

aims: in our previous studies, we showed the inhibitory effects of punica granatum l. flower and rhus coriaria l. fruit water extracts on dental plaque accumulation by several bacteria, especially streptococcus mutans (s. mutans), on orthodontic wire by in vitro assays. in this study, the anti-cariogenic properties of the extracts were evaluated by assessing their effects on expression of glyco...

The active principles of brown alga, Turbinaria conoides (J.Agardh) Kuetz. (Sargassaceae) was extracted with n-hexane, cyclohexane, methanol and ethanol-water (1:1) and investigated for acute toxicity and antipyretic activity. Phytochemical analysis of the extracts revealed the presence of steroids, flavonoids and reducing sugars. Acute toxicity study was performed in Wistar rats after administ...
