Abstract

The genus Fuchsia is generally used in herbal preparations to treat conditions caused by microorganisms. Based on the popular use of this type of plants, the objective of this study was to obtain sequential extracts of increasing polarity from the branches of Fuchsia lycioides by maceration at room temperature and by the Soxhlet method at 60oC, to later evaluate the antifungal capacity of the extracts against different clinical isolates of the Candida genus. The ethyl acetate extract exhibited strong anti-fungal activity, selectively inhibiting C. albicans strains with MIC and CMF values of 10 and 15 μg/mL, respectively; comparable with the drug itraconazole®. The analysis of the extract by GC-MS showed a high concentration of terpenoids (mainly phytol) and phenylpropanoids (mainly cinnamic acid), possibly responsible for the antifungal activity of the ethyl acetate extract of F. lycioides.

紫红色枸杞提取物对念珠菌抗真菌活性的比较研究。
樱属植物通常用于草药制剂中,以治疗由微生物引起的疾病。基于这类植物的广泛使用,本研究的目的是通过室温浸泡和60℃索氏法从Fuchsia lycioides分支中获得极性增加的顺序提取物,随后评估提取物对不同临床分离的念珠菌属的抗真菌能力。乙酸乙酯提取物具有较强的抗真菌活性,选择性抑制白色念珠菌,MIC和CMF值分别为10和15 μg/mL;可与伊曲康唑®相媲美。气相色谱-质谱分析表明,该提取物中含有高浓度的萜类化合物(主要为叶绿醇)和苯丙类化合物(主要为肉桂酸),可能是其抗真菌活性的主要原因。
