摘　　要：以茯苓为试材,在不同贮藏期、不同温度条件下（室温、1-5℃、-20℃）贮藏茯苓药材1年,定期测定其有效成分（多糖、三萜化合物）含量的变化。结果表明：随着贮藏时间的延长,不同温度条件下,茯苓中有效成分含量均呈现下降的变化趋势：前3个月多糖含量迅速下降,此后贮藏于低温条件下其降幅趋缓,而室温条件下经过3个月的稳定期后再次快速下降;三萜化合物含量在不同温度条件下呈现相同的变化趋势,表现为降低-升高-降低-平稳。Taking Wolfiporia cocos as material,Wolfiporia cocos was storaged after 1year with different temperature（room temperature,1-5℃and-20℃）conditions,and the effective composition（polysaccharide and triterpene）content regularly was determined.The results showed that under different temperature conditions,the content of effective components showed a downward trend accompanies the extension of storage time.The polysaccharide content decreased rapidly of the first 3months,thereafter the decreasing amplitude was getting smaller which stored under low temperature condition,but that stored under room temperature condition had a rapid decline after the stable period of 3months;under different conditions,triterpene compounds content showed the same change trend,first decrease rapidly,rebounded slightly,and rapid decreased again,finally tended to be stable.
