This study evaluated the anti-inflammatory effect of Kaempferia galanga (KG) using an activity-guided approach. KG rhizomes were serially extracted with petroleum ether, chloroform, methanol and water. These extracts (2 g/kg each) were tested for their ability to inhibit carrageenan-induced rat paw edema. The chloroform extract was found to exert the highest inhibition (42.9%) compared to contr...

Verbesina encelioides belongs to the Asteraceae family and also known as golden crown beard wild sunflower. In present study callus was raised from leaf explant of V. encelioides. Callus obtained on MS medium. The used for antifungal activity identification. in-vitro anti-fungal Candida albicans gave most effective response out all studied fungi, with best being displayed in methanol extract fo...

Ethological aspects and chemical communication at close-range between the sexes of Lysiphlebus testaceipes Cresson (Hymenoptera: Braconidae) have been investigated through behavioral bioassays and chemical analysis. The attractiveness toward males of whole-body extracts of females and males in hexane and acetone was evaluated, adopting male fanning behavior as a key behavioral component. Also, ...

In this research, hexane and acetone extracts of Bauhinia rufences, Securidaca longepedunculata and Ziziphus abyssinica were investigated for antibacterial activity. The phytochemical screening of the plants leaves extracts was conducted using standard methods of analyses. The effects of the two solvent extracts on the bacterial species (Escherichia coli, Psuedomonas aeruginosa, Salmonella typh...

The ethanolic extract of Aloe vera leaf skin was fractionated by liquid-liquid partition using hexane, ethyl acetate, chloroform-ethanol and butanol. The total phenolic content of the four different fractions were determined by Folin-Ciocalteu method and their antioxidant activity was essayed through some in vitro models such as the antioxidant capacity by phosphomolybdenum method, β-carotene b...

From the aerial parts of Gutierrezia microcephala (Asteraceae), four oxyflavones were isolated, namely 5,7,2'-trihydroxy-3,6,8,4',5'-pentamethoxyflavone (1); 5,7,4'-trihydroxy-3,6,8-trimethoxyflavone (2); 5,7,2',4'-tetrahydroxy-3,6,8,5'-tetramethoxyflavone (3); 5,2'-dihydroxy-3,6,7,8,4',5'-hexamethoxyflavone (4), and an ent-clerodane, bacchabolivic acid (5). Compounds 1-5, the synthetic methyl ...

This study was undertaken to evaluate the antioxidant and acetylcholinesterase inhibition properties of stems and leaves of hexane and methanolic extracts of Pluchea indica. Methanolic extract of leaves showed the highest antioxidant activity (IC50= 24.45 ± 0.34 μg/ml) and total phenolic contents (573.52 ± 6.2 mg GAE/100 g crude extract), in DPPH radical scavenging and Folin-Ciocalteu assays re...

The title compound, C(16)H(34)N(2), is a chiral diamine with fixed R configuration at both stereogenic carbon centres of the cyclo-hexane backbone. Due to their different substituents, the two N atoms also become stereogenic. In the crystal structure, the configuration at one of the two nitro-gen centres is fixed, with the free electron pair pointing inward and the isobutyl group in a trans pos...

Guided by bioassay test results, we have isolated an active compound from the hexane layer of the extract of Andrographis paniculata and it was identified as 14-deoxyandrographolide. Although this compound has been known as a medicine in Pharmacology, its antifeedant activity against insects has never been reported yet. The minimum effective dose (MED = 100μg/leaf disc) on the isolated compound...

The antileishmanial activity of extracts of Warburgia ugandensis Spraque (Canellaceae), a known traditional therapy in Kenya was evaluated in vivo. Treatment of infected BALB/c mice with W. ugandensis extracts orally resulted in a reduction of the size of lesions compared to the untreated control. The lesion sizes differed significantly for the four extracts (p=0.039) compared to the untreated ...
