The aims of this work were to study the chemical composition of the essential oil from the leaves of Pereskia aculeata and to evaluate some biological activities of three leaf extracts. The phenolic content, antioxidant activity, and in vitro antimicrobial and antifungal activities were determined. The methanol extract showed antioxidant activity (EC50 7.09 mg/mL) and high polyphenols content (...

The antimicrobial activities of aqueous, ethanolic and petroleum ether extracts of the leaves of Basella rubra were evaluated in the present study by measuring the inhibition zones using Cup Plate Diffusion method. The inhibition zones were significantly different (P<0.001) in each plant extract. The ethanolic extract showed maximum activity with zone of inhibition (14.3±1.82 mm) against E.coli...

The objective of the present study is to determine the bioefficacy of different crude extracts of Ajuga remota against anopheline and culicine larvae. Larval susceptibility of crude carbon-tetrachloride, methanol and petroleum-ether extracts of Ajuga remota leaves was observed against the malaria vector, Anopheles stephensi and the filariasis vector, Culex quinquefasciatus. Among the extracts t...

The petroleum ether (60-80o), chloroform methanol extracts of leaves and root bark of ficus glomerata (Moraceae) were prepared by successive solvent extraction followed by vacuum evaporation and the marc left after successive solvent extraction was extracts with boiling water to get aqueous extracts, all the extracts were subjected to qualitative chemical tests to find out phytoconstituents pre...

Supercritical fluid extract of leaves of Vitex negundo was tested for its antimicrobial potential and was compared with that of ethanol extract, ether extract and hydrodistilled oil of leaves. The chemical constituents of extracts were studied by chromatographic techniques. Extracts were evaluated for antimicrobial potential against bacterial strains like Staphylococcus aureus, Bacillus subtili...

The Polygonum orientale L. extracts were investigated for antibacterial activity against Clavibater michiganense subsp. sepedonicum (Spieckermann & Kotthoff) Davis et al., the causal agent of a serious disease called bacterial ring rot of potato. The results showed that the leaf extracts of P. orientale had significantly (p<0.05) greater antibacterial activity against C. michiganense subsp. sep...

In view of alleged antidiabetic potential, effect of the petroleum ether, methanol, and aqueous extracts of Terminalia catappa Linn (combretaceae) fruit, on fasting blood sugar levels and serum biochemical analysis in alloxan-induced diabetic rats were investigated. All the three extracts of Terminalia catappa produced a significant antidiabetic activity at dose levels 1/5 of their lethal doses...

Extracts of Riccinus communis were made in mid-polar solvent acetone and non-polar solvent, petroleum ether by using fresh stem, leaves and tender fruits. Bioassay and Minimum Inhibitory Concentration (MIC) was done against various gram positive and gram negative bacteria by agar cup method. Significant activity was found in all acetone extracts against mainly gram positive bacteria and some gr...

The stem bark of Carallia brachiata was studied for wound healing activity. The bark was extracted with petroleum ether, ethyl acetate and methanol successively. All the extracts were screened for wound healing activity by excision and incision models in Wistar rats. The ethyl acetate and methanol extracts were found to possess significant wound healing activity. The extracts revealed the prese...

Diplocyclos palmatus (L.) C. Jeffrey commonly known as shivalingi is a lesser heard and perennial climber having diversified medicinal values. It belongs to Cucurbitaceae family. This plants especially the leaves seeds have immense folklore usage even today. The of plant are generally applied an anti-inflammatory paste. Women take in combination with other herbs for helping conception prevent m...
