摘要

摘要本研究对海百合(Phellinus robiniae) NTH-PR1浸没菌丝(ME)和子实体(FBE)提取物的提取率、抗氧化剂含量、抗氧化能力和抗菌活性进行了评价。结果表明,产率分别为14.84±0.63和18.89±0.86%。菌丝体和子实体中均存在TPSC、TPC和TFC,且子实体中含量较多。ME和FBE中TPSC、TPC和TFC的浓度分别为17.61±0.67和21.56±0.89 mg GE g-1, 9.31±0.45和12.14±0.56 mg QAE g-1, 8.91±0.53和9.04±0.74 mg QE g-1。对DPPH自由基清除的EC50值显示,FBE(260.62±3.33 μg mL-1)比ME(298.21±3.61 μg mL-1)更有效。ME和FBE中亚铁离子螯合作用的EC50值分别为411.87±7.27和432.39±2.23 μg mL-1。因此,两种提取物均能抑制革兰氏阳性和革兰氏阴性病原菌菌株,对革兰氏阳性菌的ME浓度在25-100 mg mL-1, FBE浓度在18.75-75 mg mL-1;革兰氏阴性菌的ME为75-100 mg mL-1, FBE为50-75 mg mL-1。Ph. robiniae NTH-PR1的总淹没菌丝生物量和子实体可被认为是开发功能食品、药品和化妆品或药妆品的有用天然资源。

Antioxidant and Antimicrobial Properties of Fruiting Body and Submerged Mycelium of Medicinal Mushroom Phellinus robiniae (Agaricomycetes).

This study was conducted to evaluate extraction yield, antioxidant content, antioxidant capacity and antibacterial activity of extracts obtained from submerged mycelium (ME) and fruiting body (FBE) of Phellinus robiniae NTH-PR1. The results showed that yields of ME and FBE reached 14.84 ± 0.63 and 18.89 ± 0.86%, respectively. TPSC, TPC, and TFC were present in both mycelium and fruiting body, and the more contents of them were found in fruiting body. The concentrations of TPSC, TPC and TFC in ME and FBE were 17.61 ± 0.67 and 21.56 ± 0.89 mg GE g-1, 9.31 ± 0.45 and 12.14 ± 0.56 mg QAE g-1, and 8.91 ± 0.53 and 9.04 ± 0.74 mg QE g-1, respectively. EC50 values for DPPH radical scavenging revealed FBE (260.62 ± 3.33 μg mL-1) was more effective than ME (298.21 ± 3.61 μg mL-1). EC50 values for ferrous ion chelating in ME and FBE were 411.87 ± 7.27 and 432.39 ± 2.23 μg mL-1, respectively. Thus, both extracts were able to inhibit Gram-positive and Gram-negative pathogenic bacterial strains, at concentrations ranging in 25-100 mg mL-1 of ME and 18.75-75 mg mL-1 of FBE for Gram-positive bacteria; ranging in 75-100 mg mL-1 of ME and 50-75 of FBE for Gram-negative bacteria. Overall submerged mycelial biomass and fruiting bodies of Ph. robiniae NTH-PR1 can be considered as useful natural sources for development of functional food, pharmaceuticals and cosmetic products or cosmeceuticals.

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.
