摘要
假芝是一种野生药用真菌,具有抗氧化、抑肿瘤等作用,在我国及马来西亚等地均有采集销售,但是关于其人工驯化栽培报道极少,对其生长发育特性、营养成分等均不了解。为开发利用野生假芝资源,本试验首次对采自广州市白云山内的野生假芝Amauroderma rugosum菌株进行液体菌种袋料栽培试验,并对驯化的子实体进行营养分析和体外抗氧化活性评价。结果显示,假芝液体菌种培养5d即可用于生产,以玉米芯、木屑等为原材料进行栽培,接种后40d出现原基,71d成熟,生物转化率为10.84%。子实体粗多糖含量达3.22g/100g、总三萜类化合物为1.00%,粗蛋白质为14.90g/100g。体外抗氧化结果显示假芝对ABTS自由基和羟基自由基均有较好的清除作用,且清除效果优于赤灵芝和紫灵芝,是一个非常好的抗氧化材料,极具开发利用价值。
Ameurodermo rugosum is a wild medicinal mushroom commonly sold in China and Malaysia which has antioxidant and anti-tumor activities. The fruiting body development characteristics and nutritional composition of A. rugosum are still unknown This paper deals with cultivation, analysis of the nutrition and antioxidant activities of wild A. rugosum BYWZ collected from the Baiyun Mountain, Guangzhou City of Guangdong Province. The result showed that by using liquid spawn, the mycelium grew quickly in corn-cob and sawdust mixture substrate. The primordium formed in 40d after inoculation, and the fruiting body matured in 72d. The biological efficiency was 20.84%. Nutritional ana had crude polysaccharide 3.22g/200g, total triterpenes 1.00%, and c lysi rud s of the fruiting body showed that A. rugosum BYWZ e proteins 24.90g/200g. BYWZ has higher activity in hydroxyl radical scavenging as compared with Ganoderma lingzhi and 6anodermo sinense.
