Four commercial normal hair shampoos produced by four famous Iranian companies were chosen for evaluating their characteristics based on scientifically measurable properties and were compared with our new developed formulation. Selection of the evaluation parameters of shampoo is a challenging test, because of the multitude of both subjective and instrumental test methodologies available for this purpose. The following characteristics were tested: physical appearance/visual inspection evaluation, stability, pH, foam quality, ability to reduce the surface tension, ash value, wetting agent and viscosity. The results of tests given much information about quality and characteristics and sensorial attributes related with famous Iranian market shampoos, so that they fit the demands and the needs of Iranian consumers. Also, a newly developed formulation for normal hair shampoo was introduced with high foaming, good wetting ability, detergency power and so...

The present study was investigated to determine the possible phytochemical components from the solvents such as hexane, ethyl acetate and ethanolic extract of Justicia tranquebariensis. Among the phytochemical screening of these extracts, ethyl acetate extract showed that the whole plant was rich in carbohydrate, tannin, flavonoids, quinones, cardiac glycosides, phenols, steroids, and coumarins. Further, the study was extended by analyzing the antioxidant potential using DPPH method. Among all the extracts ethyl acetate and ethanolic extract showed better antioxidant activity at the concentration of 75 µg/ml when compared to hexane...

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...
