活性炭脱色对灵芝水提液活性成分的影响

Influence of active carbon decoloration on active constituent of water extraction of ganoderma lucidum

采用活性炭吸附法 ,研究了不同条件下 (活性炭用量、pH、温度、时间 )灵芝浸提液的脱色情况。实验结果表明 ,当活性炭用量为 1 5 % ,温度 5 5℃ ,pH =5 0 ,吸附时间 5min时 ,脱色后灵芝浸提液的抗羟基自由基活性最高 ,氨基酸的保留率为 6 8 2 % ,多糖的保留率为 86 8%。

With active carbon as decolorizer,the decoloration status of water extraction of ganoderma lucidum was researched under different conditions such as quantity of active carbon,pH,temperature,time,etc.The results showed that under the conditions of quantity of active carbon 1.5%,temperature 55℃, pH=5.0, time 5min,the anti hydroxy1 radical ability of decolored water extraction of ganoderma lucidum was the highest, the retention rate of amino acids was 68.2%, and the retention rate of polysaccharides was 86.8%.
