- 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。
- Abstract:
- Taking Wolfiporia cocos as material,Wolfiporia cocos was storaged after 1 year 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 3 months,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 3 months;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.
