In the current study, we investigated 2 species of the genus Rhodiola for the inhibition of alpha-amylase,alpha-glucosidase and angiotensin converting enzyme (ACE) inhibitory activity. Water extracts of Rhodiola crenulata had the highest alpha-amylase inhibitory activity (IC50,98.1 microg total phenolic /ml) followed by ethanol extract of R.crenulata (IC50, 120.9 microg total phenolic/ml) and e...

Hops (Humulus lupulus L.) are traditionally used to add bitterness and flavour to beer. Although the isomerised hop extracts produced by the brewing process have been thought to ameliorate lipid and glucose metabolism, the influence of untreated hop extracts on high-fat (HF) diet-induced obesity is unclear. The present study examined the anti-obesity effects of a hop extract in male C57BL/6J mi...

The effects of Mentha pulegium water extract dipping on quality and shelf life of silver carp during superchilled storage were investigated. Fish samples were treated with water extract of 1 and 3%M.pulegium, and then stored at -3 οC for 30 days. The control and the treatedfish samples were analyzed periodically for chemical (pH, PV, TBA, TVB-N), and sensory characteristics. The results indicat...

effect of adding melissa officinalis aqueous extract was studied on immune response and performance in 200 ross 308 broiler chicks in a completely randomized design with five treatments and four replicates and 10 observations per replicate. the amounts of 0 (control), 0.5, 1, 1.5 and 2 ml/l lemon balm extract were added in drinking water for 42 days. humoral immunity was evaluated by injection ...

The hypoglycemic effect of a water extract from aerial parts (0.33 g/kg) of Equisetum myriochaetum Schlecht and Cham (Equisetaceae) was analyzed in 11 recently diagnosed type 2 diabetic patients. A single dose of this extract was orally administered. Glucose and insulin were determined at 0, 30, 60, 90,120 and 180 min after administration. The same patients served as the control group and recei...

The corrosion inhibition efficiency of the vasaka leaf extract for protecting mild steel in potable water (neutral aqueous medium) was studied by weight loss, Open circuit potential monitoring and potentiometric polarization methods. The inhibition test was performed in potable water rather than deionized water because inhibitors are normally applied in neutral and industrial waters. The extrac...

The biological activities of water extract from Garcinia kola (G. kola) were investigated in growing Wistar rats. Three doses of G. kola extract (0, 10, 20 mg G. kola/100g body mass of rat) were administered daily by gavage to the respective groups of 15 rats for a period of 70 days. The animals were offered standard rat diet and water ad libitum. The plant extract had a depressive effect (P<0....

Objective: To evaluate the effects of Centella asiatica (CA) upon pain (antinociception) and inflammation in rodent models. Material and Methods: The antinociceptive activity of the water extract of CA (10, 30, 100 and 300 mg/kg) was studied using acetic acid-induced writhing and hot-plate method in mice. The antiinflammatory activity of CA was studied in rats by prostaglandin E 2 -induced paw ...

In the present study the antidiabetic potential of aqueous and ethanol extract of Cassia auriculata L. flowers was assessed in alloxan-induced diabetic rats. The phytochemical screening and antioxidant activity were made in these extracts. Antidiabetic agents (Flavonoids and phenolic acids) and free radical scavenging activity in water-soluble fraction of the ethanol extract was higher compared...

Ginseng leaf/stem extract produced by subcritical water extraction at high temperature (190°C) possess higher cytotoxic activity against human cancer cell lines than ethanol extract. Subcritical water extraction can be a great candidate for extraction of functional substance from ginseng leaves/stems.
