By orthogonal experiment,the best extraction conditions of total flavonoids from fruits and leaves of P. mume Sieb. et Zucc. were determined,and reducing ability of the extracted total flavonoids and its DPPH and ABTS scavenging abilities were explored. [Results] The best extraction technology conditions: solid-liquid ratio of 1∶ 50,ethanol concentration of 50%,extraction time of 2. 5 h,extraction temperature of 85 ℃,two-time extraction. By detecting DPPH and ABTS scavenging abilities of total flavonoids,the anti-oxidation activity of the total flavonoids from fruits and leaves of P. mume Sieb. et Zucc. was analyzed and evaluated. [Conclusions]Fruits and leaves of P. mume Sieb. et Zucc. had a certain in vitro anti-oxidation activity,and heat reflux extraction method of its total flavonoids had high extraction rate and simple and convenient operation,which had some practical value.展开更多
目的:比较山茱萸去核的作用,优选山茱萸产地加工方法和工艺。方法:比较山茱萸核和肉中的马钱素、莫诺苷含量;以马钱素含量为指标,采用正交试验分别对水烫法和烘法工艺进行优选。结果:山茱萸核中不含马钱素和莫诺苷;烘法的加热温度以及...目的:比较山茱萸去核的作用,优选山茱萸产地加工方法和工艺。方法:比较山茱萸核和肉中的马钱素、莫诺苷含量;以马钱素含量为指标,采用正交试验分别对水烫法和烘法工艺进行优选。结果:山茱萸核中不含马钱素和莫诺苷;烘法的加热温度以及水烫法的加水量和烫的时间对马钱素含量均有明显影响;在60℃烘10 m in后去核为最佳工艺。结论:山茱萸去核的作用是为了去除非药用部位,烘法软化优于水烫法。展开更多
