云南省独特的地理位置和自然环境孕育了丰富的牛肝菌资源,其品种丰富,产量巨大,但目前为止对其营养成分和功效的比较研究还很少。为此本文以白牛肝、黄牛肝、酸牛肝等六种常见牛肝菌的多糖进行研究:首先采用水提醇沉法对牛肝菌多糖进行提取,后以葡萄糖为标准采用紫外分光光度计对牛肝菌中多糖含量进行测定,最后采用DPPH和总还原力法比较了六种牛肝菌多糖的抗氧化能力。结果表明,白牛肝和酸牛肝多糖含量较高,其抗氧化能力也较强。
Yunnan Province, a unique geographical location and natural environment gave birth to a wealth of bolete resources, its variety, yield a huge, but so far its nutritional composition and efficacy of comparative studies are few. In this paper, the white bovine liver, yellow liver, bovine liver and other six kinds of common porcini polysaccharides were studied: First, the use of water extraction alcohol precipitation Boletus polysaccharide extraction, glucose as a standard using ultraviolet spectrophotometry The content of polysaccharide in bolete was measured. Finally, the antioxidant capacity of six kinds of bolete polysaccharides was compared by DPPH and total reducing method. The results showed that the content of white bovine liver and bovine liver polysaccharide is high, and its antioxidant capacity is also strong.
