In vitro anti-malarial activity of petroleum ether extracts of Ficus sycomorus leaves was investigated using Candle Jar method. The extractions were carried out through activity guided fractionation. Petroleum ether extract has the highest activity, at the concentration of 1mg and 0.5mg with percentage growth inhibition of (33.12 and 31.9%) respectively. These results suggest that the leaves of Ficus sycomorus plant have significant antimalarial activity and that the antiplasmodial agents might be as a result of the extract fractionated using the petroleum.

Objective: Present study aimed phytochemical evaluation and antimicrobial screening of petroleum ether and ethanol extracts of Santalum album seeds.Methods: Petroleum ether and ethanol extracts were screened for presence of chemical constituents. Petroleum ether extract was investigated detail by using chromatographic and spectroscopic methods. In vitro antimicrobial activity of both extracts were investigated using disc diffusion method on two gram-positive bacteria, Bacillus subtilis, Staphylococcus aureus, gram negative Pseudomonas aeruginosa, Escherichia coli and fungus Candida albicans.Results: Santalbic acid was identified in petroleum ether extract and content determined by HPTLC was 4.7%w/w. It was seen that petroleum ether extract have MIC value for B. subtilis, P. aeruginosa, E. coli and C. albicans were 78.125 µg/ml, 19.331 µg/ml, 625 µg/ml & 39.062 µg/ml respectively while MBC was 39.062 µg/ml, 4.882 µg/ml, 312.5 µg/ml & 9.765 µg/ml,  respectively. Petroleum ether extract showed MIC and MBC values for S. aureus was similar as 156.25µg/ml. So, the petroleum ether extract showed significant antimicrobial activity against both gram positive, gram negative and fungal strain.Conclusions: The results of present investigations were indicative of possible high potency of petroleum ether extract due to santalbic acid which could serve as chemotherapeutic agent.

The seeds of Helianthus annuus have been investigated for the presence of various chemical components and biological activities with special emphasis to the anti-oxidant, antimicrobial, cytotoxic and thrombolytic assay. The results of standard phytochemical analysis revealed the presence of tannins, saponins, flavonoids, carbohydrates, steroids, fixed oils and vitamins. In vitro antioxidant activity of methanolic seed extract of H. annuus was determined by DPPH free radical scavenging assay, which demonstrated very significant antioxidant potential compared to standard antioxidant (ascorbic acid). In case of antimicrobial assay, the methanolic and ethyl acetate extract of H. annuus seeds showed high sensitivity to Salmonella typhi and moderate sensitivity to Pseudomonous aeuregenosa. The petroleum ether extract revealed high sensitivity to P. aeuregenosa. The methanolic extract of H. annuus displayed LC50 1.2 ug/ml and its petroleum ether extract showed LC50 of 1.1 ug/ml, which indicated significant cytotoxicity.Bangladesh Pharmaceutical Journal 19(1): 100-105, 2016

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder of the elderly people. Cholinergic dysfunction and oxidative stress have been found to be related with the development of the disease. Typhonium trilobatum L. Scott has been used traditionally in folk medicine as a central nervous system stimulant. In this study, we have investigated the various extracts of T. trilobatum for acetylcholinesterase and antioxidant activities in vitro. All the tested extracts exhibited inhibition against acetylcholinesterase. Petroleum ether extract exhibited the highest inhibition with an IC50 of 255.26 g/ml. Likewise all the extracts were found to possess antioxidant activity. In reducing power assay, petroleum ether extract showed the highest reducing power with an absorbance of 0.874 at 0.1 mg/ml concentration and in DPPH radical scavenging assay, chloroform extract exhibited the highest scavenging activity with an IC50 of 619.54 µg/ml. Phytochemical analyses of the four extracts revealed that the ethyl acetate extract contained the highest amount of flavonoids and petroleum ether had the highest amount of phenolics. These results suggest that T. trilobatum has both antioxidant and cholinesterase inhibitory activities, which may be useful in reducing the risk of AD.

AbstractThe hyperforin content of Hypericum perforatum herb was repeatedly reported to be responsible for a multitude of pharmacological activities. Our recent report about the hyperforin accumulation in in vitro root cultures of H. perforatum provides an alternative perspective to achieve constant product quality and to serve the rapidly growing market. In this study, the antiproliferative effect of a petroleum ether extract from the in vitro root cultures was investigated. When normalized to 1 µM hyperforin content, the extract reduced the viability of human keratinocytes (HaCaT) and human dermal fibroblast monolayers to 33 and 36%, respectively, after 72 h of incubation. A cytotoxicity assay and live-dead cell staining confirmed that the extract lacked a cytotoxic effect and that the reduction in cell viability was mainly due to the antiproliferative activity. Application of the 1 µM hyperforin-normalized extract to a 3D artificial skin construct significantly reduced the proliferation of HaCaT in the presence of fibroblasts. This effect was proved by the reduction in thickness of the epidermal construct from 100 µm (control) to 17 µm (treated). Notably, 1 µM pure hyperforin lacked effectiveness in both monolayer cultures and 3D artificial skin constructs. Nor were fractions of the extract containing colupulone and xanthones active. The combination of these constituents also failed to reassemble the antiproliferative activity, which indicates a synergistic role of yet unidentified components present in the extract. Our findings may introduce H. perforatum root cultures as a novel lead system for the treatment of hypertrophic scars.
