Candidiasis and pityriasis versicolor are opportunistic fungal infections that are caused by spp. and spp. yeasts. Conventional drugs like azole and amino derivatives are known to treat fungal skin diseases. However, drawbacks like long-term side effects and drug resistance lead to investigate on antifungal properties of phytochemicals as an alternative to available synthetic drugs.
The herbal nano hydrogel was successfully synthesized from Quince Seed extract followed by ultrasonic treatment and it has been formulated using a mixture of essential oils. We evaluated the antifungal in vitro assay for a mixture of essential oils in combination with herbal nano hydrogel against and strains by micro dilution method.
The results indicated that essential oils possess antifungal activity with the MIC value of 12.5 and 6.24 mg/ml against and , respectively. No fungicidal effect was reported for the herbal hydrogel before nanofabrication while it shown some antifungal activity after ultrasonic treatment for 5 and 10 minutes. As anticipated; the antifungal property of essential oil mixture was appreciably improved when it combined with herbal nano hydrogel where the highest level of inhibition was observed at concentration of 3.125 mg/ml for both strains. The loss in biological activity observed when the ultrasonic treatment on herbal nano hydrogel performed for longer time.
The proposed plant-based nano formulation shown promising in vitro antifungal activities against and strains and its antifungal properties were comparable with commercially available agents like clotrimazole. The new formulation expected to be safe with minimum long-term side effects. Further investigations are underway to confirm the safety and the mechanism of the action of this new herbal formulation.
念珠菌病和花斑癣是由特定酵母菌种引起的机会性真菌感染。已知唑类和氨基衍生物等传统药物可治疗真菌性皮肤病。然而,长期副作用和耐药性等缺点促使人们研究植物化学物质的抗真菌特性,以替代现有的合成药物。
从温柏籽提取物成功合成了草药纳米水凝胶,随后进行超声处理,并使用精油混合物进行了配方。我们通过微量稀释法评估了精油混合物与草药纳米水凝胶联合对特定菌株的体外抗真菌试验。
结果表明,精油具有抗真菌活性,对特定菌株的最低抑菌浓度(MIC)值分别为12.5和6.24毫克/毫升。在纳米制备之前,草药水凝胶未显示出杀菌作用,而在超声处理5分钟和10分钟后显示出一些抗真菌活性。正如预期的那样,当精油混合物与草药纳米水凝胶联合使用时,其抗真菌性能得到显著改善,两种菌株在浓度为3.125毫克/毫升时均观察到最高抑制水平。当对草药纳米水凝胶进行较长时间的超声处理时,观察到生物活性丧失。
所提出的基于植物的纳米制剂对特定菌株显示出有前景的体外抗真菌活性,其抗真菌特性与克霉唑等市售药物相当。新制剂预计安全性高,长期副作用最小。正在进行进一步研究以确认这种新草药制剂的安全性和作用机制。
