OBJECTIVE To investigate mosquitocidal effects of ethanolic extract of flowers of Tagetes erecta (T. erecta) and its chloroform and petroleum ether soluble fractions against the larvae of Culex quinquefasciatus (Cx. quinquefasciatus). METHODS The fresh flowers of T. erecta were extracted in cold with ethanol (5.0 L) and after concentration, the ethanol extract was fractionated with chloroform...

Phlomis lanceolata is a medicinal plant that has long been used to treat various conditions such as diabetes, gastric ulcer, hemorrhoids, inflammation and wounds. As most of Phlomis species have shown cytotoxic activity against proliferation of different cell lines, a biological investigation of P. lanceolata was carried out in this study. The aim of this study was to find out the in vitro cyto...

Mirabilis Jalapa Linn. is a widely used traditional medicine in many parts of the world for the treatment of various diseases viz. virus inhibitory activity, anti tumour activity. It is claimed in traditional medicine that the leaves of the plant are used in the treatment of inflammation. In the present study, the total alcoholic extract and successive petroleum ether fractions of leaves of Mir...

The petroleum ether and chloroform fractions of ethanol extract of leaf and stem from the plant Passiflora edulis (Fam: Passifloraceae) was subjected to antioxidant, antibacterial and cytotoxic activity. All the fractions showed potent antioxidant activity, of which the chloroform and petroleum ether fraction of stem demonstrated the strongest antioxidant activity with the IC50 value of 51.28 μ...

The discovery in this laboratory by Lynch and French (1) that A3-carotene partially restores the photochemical activity lost by petroleum ether extraction of chloroplasts suggests that this pigment is ain active component of the photosynthetic mechanism. This observation prompted the present inquiry to determine whether ,8-carotene is specific for such reactivation or whether other fat soluble ...

Column chromatography of the dichloromethane fraction from an aqueous methanolic extract of fruit peel of Citrus pyriformis Hassk. (Rutaceae) resulted in the isolation of seven compounds including one coumarin (citropten), two limonoids (limonin and deacetylnomilin), and four sterols (stigmasterol, ergosterol, sitosteryl-3-beta-D-glucoside, and sitosteryl-6'-O-acyl-3-beta-D-glucoside). From the...

The chloroform extract of Ferula persica var. persica roots was found to inhibit red pigment production of Serratia marcescens. A bioguided fractionation study by preparative thin layer chromatography (PTLC) detected a fraction (Rf = 0.71, petroleum ether/EtOAc, 2:1 v/v), which was effective on depigmentation of Serratia marcescens. Using conventional spectroscopy methods, the active fraction w...
