Dalbergia latifolia commonly known as bilayatti shisham (Fabaceae) is a medicinal plant. The dry bark is brown colored astringent characters. Traditionally various species are reported to be used as aphrodisiac, abortifacient, expectorant, anthelmintic, antipyretic, appetizer, allays thirst, vomiting, burning sensation, cure skin diseases, ulcers Ayurvedic practice, bark is used as leucoderma, leprosy edema and bladder disorder. The bark minerals, acids, phenolic compounds, flavonoids, have characteristic smell astringent taste. This study deals with the pharmacognostical evaluation of the dried bark of Dalbergia latifolia which includes macro and microscopic studies, determination of...

Homalium letestui Pellegr (Flacourtiaceae) used traditionally by the Ibibios of Southern Nigeria to treat stomach ulcer, malaria and other inflammatory diseases were evaluated for antiulcer activities of the stem extract and its fractions. The effects of ethanol stem extract of H. letestui (200-600 mg/kg) and fractions (Aqueous and dichloromethane, 400 mg/kg) on experimentally induced ulcer were studied in rats using ethanol, indomethacin, reserpine, and histamine-induced ulcer models. The extract (200-600 mg/kg) inhibited ethanol, indomethacin, reserpine, and histamine-induced ulcer models in a dose-dependent fashion. The various degrees of inhibitions were statistically significant (P<0.05, 0.01, 0.001). The effects of the extract/fraction were comparable to that of the standard drugs used in indomethacin and ethanol-induced ulcer models with the dichloromethane fraction having the highest activity. Thus, H. letestui extract demonstrated a good antiulcer activity which supports the use of this plant in traditional...

Misfolding of some proteins, their self-assembly into insoluble amyloid structures underlies many diseases, constituting a group of amyloid-related pathology. Fibrillation of peptide hormone of the pancreas, amylin, is considered as one of the causes of death of β-cells in type 2 diabetes. In this work we studied in-vitro protection of islet β-cells from death in the presence of aggregated amylin by ethanol extracts of rose petals (Rosa damascena), melilot (Melilotus officinalis), leaves of grape (Vitis vinifera), sorrel (Rumex confertus) and blackberry (Rubus caesius), and by eleven fractions, isolated from these plants (Coumarin, phenol glycoside, flavonoid and anthracene derivative). A rather low IC50 values in protection of β-cells were estimated for the extracts (0.03-1.5 µg/ml) and their fractions (0.04-3.9 µg/ml). The inhibition of amylin aggregation by several plant extracts and fractions in-vitro was studied using ThT fluorescence method. The IC50 values in deceleration of the peptide aggregation were between 1.76-7.24 µg/ml. A strong correlation (r = 0.99, p=0.0005) was observed between IC50 values in the protection of β-cells and amylin...

Butea monosperma var. lutea, a native of India, is commonly known as “Palash” and popularly known as “Flame of Forest.” Traditionally it has been found that flowers have antimicrobial, wound healing, antifungal, antidiarrhoeal, hypoglycemic, hepatoprotective, antioxidant, anthelmintic, anti-convulsive, antistress, antidiabetic, anti-inflammatory activity. In the present study, crude hydroalcoholic flower extract was examined for anticancer activity. To determine in-vitro anticancer activity, different concentrations of crude extract were tested on MCF-7 breast cancer cell line by 3-(4,5-dimethyl thiazole-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The extract showed significant antiproliferative activity and a dose-dependent effect. Minimum inhibition 16.8% was shown by extract at concentration 62.5 µg/ml and maximum inhibition (46.89%) observed at 500 µg/ml. The flower extract showed activity in the potential range for further investigation of cancer cells....

Phytochemicals are the best remedies to all kind of diseases and disorders throughout the world. There are a lot of plants, and its sources are playing a role as a heart, liver and kidney savers. In our present investigation, the famous fruit tree Annona squamosa (Annonaceae) leaves extract used for the hepatoprotective activity. The phytochemicals present in the aqueous leaves extracts were analyzed using preliminary biochemical analysis, and functional groups are characterized using Fourier Transform Infrared Spectrophotometer (FT-IR). The animals were divided into six groups, in that apart from the first group (normal control), five groups are induced with paracetamol (acetaminophen) with standard drug and two plant drug extracted by aqueous one is induced control. The increasing of enzymes and bilirubin, triglycerides and cholesterol and decreasing protein shows the liver damage. These levels are changed into normal range indicates efficiency of our plant drug. The histopathalogical results are also confirmed our hepatoprotective capability is...
