Abstract

During this study, ethanol extracts of four edible mushrooms i.e., Macrocybe gigantea, Podaxis pistillaris, Lentinus tigrinus, and Pleurotus cystidiosus were prepared and investigated by TFC, TPC, FRAP, ABTS and DPPH for their antioxidant potential. The extracts were also used to check the oxidative stabilization of sunflower oil for a period of 45 d using standard methods i.e., peroxide value, free fatty acid contents and iodine value. M. gigantea extract showed the maximum flavonoids and phenolic contents and exhibited the maximum antioxidant potential among the four edible mushrooms. BHA was observed to have maximum oil stabilization potential followed by the ethanol extract of M. gigantea of 1000 ppm concentration, BHT and extract of 1000 ppm concentration of P. pistillaris. Thus, it is concluded from this study that ethanolic extracts of these mushrooms can be used as a healthy supplement to stabilize oil by replacing synthetic antioxidants that are harmful to humans.

利用巴基斯坦腐生可食用菌乙醇提取物研究葵花籽油的抗氧化潜力及稳定性。
本研究制备了4种食用菌(Macrocybe gigantea, Podaxis pistillaris, Lentinus tigrinus, Pleurotus cystidiosus)的乙醇提取物,并采用TFC、TPC、FRAP、ABTS和DPPH对其抗氧化能力进行了研究。采用标准方法(过氧化值、游离脂肪酸含量和碘值)测定葵花籽油45 d的氧化稳定性。四种食用菌中,巨茶提取物类黄酮和酚类物质含量最高,抗氧化潜力最大。结果表明,BHA具有最大的油稳定潜力,其次是1000ppm浓度的大茶乙醇提取物、BHT和1000ppm浓度的雌蕊草提取物。因此,本研究得出结论,这些蘑菇的乙醇提取物可以作为一种健康的补充剂,通过取代对人体有害的合成抗氧化剂来稳定油。

期刊介绍: The rapid growth of interest in medicinal mushrooms research is matched by the large number of disparate groups that currently publish in a wide range of publications. The International Journal of Medicinal Mushrooms is the one source of information that will draw together all aspects of this exciting and expanding field - a source that will keep you up to date with the latest issues and practice. The International Journal of Medicinal Mushrooms published original research articles and critical reviews on a broad range of subjects pertaining to medicinal mushrooms, including systematics, nomenclature, taxonomy, morphology, medicinal value, biotechnology, and much more.
