由于其代谢产物具有多种生物活性，芦荟已在全球范围内用于制药，食品和化妆品行业。本研究的目的是评估叶提取物的抗真菌和抗氧化活性。用琼脂扩散法测定了其对植物和人体病原真菌的抑菌活性。所研究的提取物的甲醇和乙醇部分比乙酸乙酯部分更具有生物活性。除白色念珠菌外，对植物病原体的活性比对人类病原体的活性更显著。这表明该提取物具有治疗植物真菌感染的潜力。采用DPPH自由基清除法测定芦荟提取物的抗氧化活性。因此，芦荟提取物作为天然抗氧化剂已被用于医疗和防腐目的的健康食品中。
Aloe vera has been used worldwide both for pharmaceutical, food, and cosmetic industries due to the plethora of biological activities of some of its metabolites. The aim of this study was to evaluate the antifungal and antioxidant activities of the leaf extract. The antifungal activity was determined by the agar-well diffusion method against plant and human fungal pathogens. The methanol and ethanol portions of the extracts studied were more bioactive than ethyl acetate portion. It was also observed that the activity was more pronounced on plant pathogen than human pathogen except Candida albicans. This is an indication that the extract has the potential to treat plant fungal infections. The Aloe extract showed the significant antioxidant activity by the DPPH radical scavenging method. Therefore, the Aloe extract provided as natural antioxidant has been used in health foods for medical and preservative purposes.
