外阴念珠菌病是女性常见的真菌感染。在这项研究中,评价了柏氏无水酒精提取物(PiHE)及其馏分对阴道念珠菌的抗真菌和抗毒活性。从PiHE获得的二氯甲烷(DCMF)和乙酸乙酯馏分(EAF)有效抑制病原体。使用电喷雾电离质谱鉴定提取物中的主要化合物。通过肉汤微量稀释测定法确定最小的抑制浓度和杀真菌浓度(分别为MIC和MFC)。此外,我们评估了提取物和级分对白色念珠菌毒力特性的影响,并确定了它们对RAW

外阴念珠菌病是女性常见的真菌感染。在这项研究中,评价了普拉藤果无水酒精提取物(PiHE)及其馏分对阴道念珠菌的抗真菌和抗毒活性。

从普拉藤果的叶子(PiHE)获得的二氯甲烷(DCMF)和乙酸乙酯馏分(EAF)有效抑制病原体。使用电喷雾电离质谱鉴定提取物中的主要化合物。通过肉汤微量稀释测定法确定最小的抑制浓度和杀真菌浓度(分别为MIC和MFC)。此外,我们评估了提取物和级分对白色念珠菌毒力特性的影响,并确定了它们对RAW 264.7细胞的细胞毒性作用。

结果,研究人员发现提取物中的化合物是类黄酮苷,主要是槲皮素和杨梅素的衍生物。提取物显示出抗真菌潜力,EAF的最低MIC值(1.3 mg / mL),并抑制念珠菌的粘附和生物膜形成。EAF破坏了48小时的生物膜,抑制率超过90%。提取物及其馏分未显示出细胞毒性。抗真菌作用归因于这些提取物改变线粒体膜电位的能力,以释放胞浆中促凋亡因子。

总之,该研究结果表明,PiHE和EAF可以作为开发针对真菌感染的新治疗方法的新型候选药物。
