The mycological analysis of stored seed of groundnut (Arachis hypogaea) through agar plate as well as blotter paper methods of study revealed presence of 16 fungal species viz., Alternaria alternata, Aspergillus candidus, Aspergillus flavus, A. Niger, A. ochraceous, A. phoenicis, A. tamari, A. terreus, A. sydowi, Fusarium moniliforme, F. oxysporum F. solani, P. glabrum, Rhizopus nigricans, Trichoderma viride and Trichothecium roseum. Out of 20 essential oils extracted from leaf of plants and assessed for their antifungal potential only leaf oil of Tinospora cordifolia,(Willd.) Miers ex Hook. F. & Thoms exhibited absolute toxicity (100%) against dominant fungi Aspergillus flavus, A. niger at 400 ppm concentration. This showed fungicidal activity at 500ppm.It showed MIC against 10 fungi at 400ppm, controlled 15 fungi at 600 ppm. There was no ill effect of physical factors viz., temperature treatment up to 100 °C, autoclaving at 15 lb/square inch pressure at 120 °C and storage up to 105 days on activity of leaf oil. In vivo studies depict that oil of T.cordifolia as seed dressing...

The skin has been used as a medium for systemic delivery of therapeutic agents. The resistance provided by the stratum corneum is the major barrier in delivering of the agents through skin. Due to this the number of drug molecules used under this category is limited. Iontophoresis is an efficient technique for physically enhancing conveyance of molecules across skin for local and systemic effects. The main feature offered by iontophoresis is the control offered by it in dose modulation by adjustment of current applied to undergo the process. It is suitable as an alternative for parenteral route as it is pain free and cost effective technique. The flux associated with iontophoretic treatment is described along with its applications in the article. The future aspects of iontophoretic treatment and the medications currently available are included in this article. Iontophoresis as a treatment regimen has gained popularity in relatively less treatment methodology but the concept should be well popularized as it offers enhancement to transdermal drug delivery system. This system being...

The present study instantiates the phyto-fabrication of silver nanoparticles by utilizing Petrea volubilis L. leaf broth which were instantaneously synthesised, eco-friendly, and cost-effective. The influence of physico-chemical parameters viz. contact time, leaf broth quantity, pH, temperature, and silver nitrate concentration were investigated and optimised to engineer infinitesimal nanoparticles. The SPR bands obtained from UV-vis spectroscopy confirmed the synthesis of silver nanoparticles. The active phytochemicals in Petrea volubilis L. leaf broth namely carboxylic acids, phenolic compounds and aldehydes were found to be responsible for the bio reduction and capping of silver ions according to FT-IR spectroscopy. The capping molecules of NPs were negatively charged and were passably stable as revealed by zeta potential measurements and the XRD patterns illustrated their crystallinity. HRTEM microphotographs enumerate spherical shaped nanoparticles. The EDS analysis at 2θ confirms the synthesis of elemental silver. The nanoparticles were evaluated for their antimicrobial activity. The highest anti-bacterial activity was observed against S. aureus as compared to the bacteria S. typhi and A. flavus a fungus. The leaf extract...

Herbal medicines are effective in the treatment of various ailments. Very often these drugs are unscientifically exploited and / or improperly used. Therefore plant drugs deserve detailed studies in the light of modern science. The detailed investigation and documentation of plants used in local health traditions and pharmacological evaluation of these plants and their taxonomical relatives can lead to the development of invaluable plant drugs for many diseases. The present study has made an attempt to demonstrate the hepatoprotective activity of aqueous and alcoholic root extracts containing and in protecting the CCl4 induced hepatocellular damage. The aqueous root extract of Aegle marmelos showed the presence of carbohydrates, phenols, flavonoids, glycosides, saponins and terpens, proteins and steroids. Significant amount of steroids were present. The alcoholic root extract of Aegle marmelos showed the presence of alkaloids, carbohydrates, phenols, flavonoids, glycosides, saponins and terpens, proteins and steroids. The aqueous and alcoholic extract of given root extracts at two dose levels 200 mg/kg and 400 mg/kg body weight administered orally for five days...

Objective: This study aimed to investigate the in vitro effect of the extracts of five Iranian medicinal herbs on Histomonas meleagridis protozoan parasite. Methods: This study was conducted in the following three phases in Khorramabad, Iran, in 2016: 1) preparing and extracting the 5 medicinal herbs Dracocephalum kotschyi, Satureja khuzestanica, Pulicaria gnaphalodes, Olea europaea, and Echinophora platyloba DC; 2) culturing the positive cases of fecal samples in the fortified commercial medium RPMI1640 up to 1×106 parasite/ml of the parasite; and 3) investigating the effect of 1.25, 2.5, and 5 mg/ml densities of each extract and metronidazole compared with the negative control on hours 2, 4, 6, 24, and 72 with Trypan blue vital stain. Results: In this study, the D. kotschyi extract which destroyed 80% of the parasites in the first two hours was the most, and the S. khuzestanica extract was the second effective extract. However, metronidazole destroyed 60% of the parasites in the first two hours and 100% in the third day and may be excreted before...
