Pileus and stipe of mushroom Russula griseocarnosa from South China were analyzed separately for chemical composition and antioxidant activities. The wild mushroom species proved to have antioxidant potential, using assays of reducing power, chelating effect on ferrous ions, scavenging effect on hydroxyl free radicals, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The mushroom contained very useful phytochemicals such as phenolics, flavonoids, ergosterol, and beta-carotene. The phenolic composition of R. griseocarnosa was analyzed by high-performance liquid chromatography (HPLC). The major component in R. griseocarnosa was quercetin (95.82 microg/g). The combination of bioactive substances and rich nutritional composition (high contents in protein and carbohydrates, low content in fat) in the mushroom should be useful to consumers in encouraging them to utilize the nutritive potential of this edible wild mushroom.
分别分析了来自中国南方的灰树花蕈盖和蕈柄的化学成分和抗氧化活性。该野生蘑菇品种具有抗氧化潜力，通过还原力、亚铁离子螯合作用、羟基自由基清除作用和 2,2-二苯基-1-苦基肼（DPPH）自由基清除活性测定。蘑菇含有非常有用的植物化学物质，如酚类、类黄酮、麦角固醇和β-胡萝卜素。通过高效液相色谱（HPLC）分析了 R. griseocarnosa 的酚类成分。R. griseocarnosa 的主要成分是槲皮素（95.82μg/g）。生物活性物质和丰富的营养成分（蛋白质和碳水化合物含量高，脂肪含量低）的结合，应该对消费者有用，鼓励他们利用这种可食用野生蘑菇的营养潜力。
