Evaluation of Formulated Anti-dermatophyte Creams from Ethanol Extract of Mitracarpus villosus Leaves

Microsporium, Trichophyton, and Epidermophyton are asexual fungi usually called dermatophytes. They are known to cause a kind of skin diseases called dermatophytosis. There have been reported cases of resistance by the dermatophytes with prolonged usage of synthetic antifungals on the skin. The aim of this study was to formulate herbal antifungal cream containing extract of Mitracarpus villosus as an anti-dermatophytic preparation and evaluate its physicochemical properties, stability and efficacy of the product. The formulated creams containing 0.5, 1 and 2% w/w of extract were subjected to stability tests using temperature variation method at -10, 4, 30, 37 and 45oC. Freeze-thaw test, Centrifuge test, pH and exposure to UV light test were also carried out using standard method. Efficacy of the cream formulations were determined using Wistar rats as experimental animals. The percentage yield of the extract was (2.1%). Percentage ethanol phytochemical composition indicated that for alkaloid it is 1.06±0.04%, saponins (0.96±0.07%), flavonoids (0.06±0.02%) and tannins (0.04±0.01%). The emulsion produced was an oil-in-water emulsion and had a white colour with pH of 7.02, spread of emulsion, rubbing-in effect and stability to centrifugation was very high. The antifungal results showed the activity against the dermatophytes to be in the increasing order Epidermophyton floccosum (9 mm) <Microsporum audounii (12 mm) <Trichophyton mentagrophtes (13 mm) <M. furfur (12 mm).Temperature stability and Centrifuge testing indicated that the formulations were stable. Light testing indicated no change in the colour of the products. Animal studies evaluation of the formulations of the cream indicated that their efficacy against the dermatophytes is concentration dependent and is in the increasing order M. audounii (34 µm) = E. floccosum (34 µm) <T. mentagrophyte (35 µm) <M. furfur (45 µm) which shows that 2% Mitracarpus villosus cream was statistically significant (P<0.05) against all the test microorganisms.

The Stability

There are scientific reports of medicinal plants having curative properties. These properties may be due to the presence of various phytochemicals in the plants. Cassia alata is a specie in the Fabaceae family. The purpose of this study is to determine the antidermatophyte activity of the extract, formulate a cream with the extract and determine the stability of the cream by measuring the pH, Free-thaw test, Centrifugation and sensitivity to light. We also subjected the formulated cream to temperature variation test at -10, 4, 30, 37 and 45o C. The percentage yield was 8.5%. The extract contain alkaloid (4.24±0.24%), saponin(1.35±0.39%), tannin (0.45±0.29%) and flavonoid (2.42±0.32%) respectively. The antifungal test results showed the activity against the dermatophytes to be in the increasing order M.furfur (12± 0.2 mm) < Microsporum audounii (12±0.4 mm) < Trichophyton mentagrophtes (14±0.2mm) < Epidermophyton floccosum (16±0.2 mm).Temperature stability and Centrifuge testing indicated that the formulations were stable. Light testing indicated no change in the colour of the cream. Our study showed that the plant has high potential as an anti-dermatophyte when formulated as a cream for topical use. The stability of the cream formulations indicated that it can be used for the management of dermatophytosis.

In this study, antimicrobial spectrum of erythorbyl laurate (EL) against bacteria and fungi, leading to food-borne and infectious skin diseases, was evaluated for its practical applications in food and cosmetics. Furthermore, the influences of environmental factors including pH, oxidative stress, and dispersion medium on antimicrobial activity of EL were investigated. The three Gram-positive bacteria and the three molds were susceptible to 3.0 mM EL, while the yeast was susceptible to 6.0 mM EL. It was demonstrated EL retained antibacterial activity against Staphylococcus aureus after being oxidized while the antibacterial activity against the three Gram-positive bacteria including S. aureus, Bacillus cereus, and Listeria monocytogenes was significantly enhanced as decrease of pH from 7.0 to 5.0. Moreover, EL exhibited bactericidal effects against both Gram-positive and Gram-negative bacteria in an oil-in-water emulsion. Treatment of 5.0 mM EL for 4 h reduced 5.29 ± 0.24, 6.01 ± 0.18, 5.95 ± 0.13, and 6.24 ± 0.30 log CFU/mL against S. aureus, L. monocytogenes, Pseudomonas aeruginosa, and Escherichia coli, respectively. In a multipassage resistance selection study, it was observed minimum inhibitory concentrations of EL against S. aureus were not increased over 20 passages, indicating EL might not develop drug resistance of bacteria. This study suggests EL has a potential to be applied as the multifunctional additive in food and cosmetics.

Pentazocine (PTZ) is a narcotic analgesic used to manage moderate to severe, acute and chronic pains. In this study, PTZ loaded Ethyl cellulose microsphere has been formulated for sustained release and improved bioavailability of PTZ. These microspheres were fabricated by oil in water emulsion solvent evaporation technique. A three factorial, three levels Box-Behnken design was applied to investigate the influence of different formulation components and process variables on the formulation response using the numeric approach through the design expert® software. All the formulations were characterized for the morphology, different physicochemical properties and the results were supported with the ANOVA analysis, three dimensional contour graphs and regression equations. The maximum percentage yield was 98.67% with 98% entrapment of PTZ. The mean particle size of the formulations ranges from 50–148μm, which directly relates to the concentration of polymer and inversely proportional to the stirring speed. SEM revealed the spherical shape of PTZ microspheres with porous structures. These are physically, chemically and thermally stable as confirmed through Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (PXRD) and thermal gravimetric (TG) analysis respectively. The microspheres provided a sustained release of the PTZ for more than 12 hours, following zero order with fickian and non fickian diffusion. The results indicate that prepared microspheres can be a potential drug delivery system (DDS) for the delivery of PTZ in the management of pains.
