Background: Dermatophytosis/Tinea/ringworm is one of the most infectious diseases of humans, caused by invasion of stratum corneum by dermatophytic fungi viz. Trichophyton species, Microsporum species and Epidermophyton species, though not fatal infections are unpleasant, unhygienic to have and re-occurrence is very common. In recent years, especially during and after COVID 19 pandemic, the development of natural products to produce more cost-effective remedies for different diseases that are affordable to the common man is now being explored from plants. Euphorbia hirta of the family Euporbiaceae is well known for its medicinal properties in traditional and folklore medicinal systems. Euphorbia hirta possesses antifungal properties that may be effective against dermatophytic fungi responsible for causing ringworm. Materials and Methods: Different parts of the plant were taken for the extraction of flavonoids by a well-established protocol with some modifications. Agar well diffusion method, Two-fold dilution method and Total activity determination were carried out to establish the antidermatophytic activity of flavonoids from different parts of the plant Results: Significant Inhibition Zone (IZ) and Activity Index (AI) were observed against Microsporum canis, Trichophyton rubrum, and Epidermophyton floccosm from free flavonoid of the leaf; bound flavonoid of fruit; and bound flavonoid of the root. The Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal Concentration (MFC) recorded were more or less similar to that of standard drugs. Conclusion: The present study suggests metabolite profiling of different parts of E. hirta. Flavonoids from the plant could be used as a source for the development of alternative drugs for the topical treatment of dermatophytosis.

Background: Dermatophytoses are responsible for almost one-quarter of all fungal infections globally. When treatable, these challenging fungal infections of the skin, hair, and nails are becoming more resistant to standard antifungal medications and frequently call for lengthy therapeutic regimens. Objectives: Essential oils have been used to cure a range of diseases for ages. In present study combination effect of volatile oils obtained from Trachyspermum ammi, Coriandrum sativum and Cymbopogon martinii were evaluated against four selected dermatophytic fungi namely Microsporum canis, M. fulvum, Trichophyton rubrum and T. mentarophytes. Materials and Methods: Four combinations like T. ammi + Cymbopogon martinii, T. ammi + Coriandrum sativum, Cymbopogon martinii + C. sativum, T. ammi + Cymbopogon martinii + C. sativum were prepared and evaluated through semisolid agar antifungal susceptibility methods. Results: During present investigation T. rubrum was found to be most resistant fungus. Combination of T. ammi with C. sativum showed excellent results as compared to T. ammi and C. martinii. Combination of C. martinii and C. sativum was less effective as compared to other combinations. MIC was ranging from 0.1 μL/mL to 0.4 μL/mL against test fungi. Conclusion: Although essential oils are frequently combined in the use of aromatherapy to cure infectious disorders, there is very little data to back up this practice. This study supports the concurrent usage of blended essential oils in some way.

Background: Cymbopogon citratus commonly known as lemon grass is a valuable medicinal plant. In present investigation variation in the antidermatophytic potential of C. citratus essential oil was estimated in different temperature and storage periods. Materials and Methods: C. citratus essential oil was extracted through hydrodistillation methods and kept in amber bottles in three different temperature conditions like room temperature (variable from 8-45{\textdegree}C), refrigerator temperature(2-6{\textdegree}C) and 30{\textdegree}C for 2 years. Minimum inhibitory concentration was determined after every fourth month of storage against selected dermatophytes. Results: Antidermatophytic activity of C. citratus oil was found prominent due to high concentration of citral derivatives. MIC was found to be stable against Trichophyton rubrum (MTCC 296) (0.1μL/mL) and T. mentagrophytes (MTCC 7687) (0.1μL/mL) at the end of experiment in all three temperature conditions. 30{\textdegree}C temperature condition was also found quite stable. A very slight increase of MIC was found against Candida albicans (MTCC 3018) and Microsporum fulvum (MTCC 2837) at 24 months (Sixth testing) of storage. Oil stored at room temperature showed variation in MIC as compared to initial one. MIC was found to double against M. fulvum (MTCC 2837) at sixth testing (0.4μL/mL) of storage as compared to first testing (0.2μL/mL). Conclusion: Present work concluded that essential oil stored in low temperature condition can maintained their primary composition and properties for long time. Therefore, storing of essential oil products in low temperature (below 8{\textdegree}C) condition is best practices for long time application of medicinal products.
