该文研究了不同变温干制条件对白花丹参有效成分的影响,为优选白花丹参产业化干制工艺提供基础。为保证丹参活性成分含量,设计多种变温干制工艺,分别为低温30℃高温60℃、低温30℃高温70℃、低温30℃高温80℃、低温40℃高温60℃、低温40℃高温70℃、低温40℃高温80℃,采用鼓风干燥箱对白花丹参进行变温干制,利用HPLC测定不同干制条件下白花丹参中的有效成分含量变化;采用SPSS 17.0统计软件分析数据。结果显示当采用低温40℃-6 h-高温80℃干制3 h的工艺时,丹参中二氢丹参酮、隐丹参酮、丹参酮Ⅰ和丹参酮Ⅱ_A的含量最高,质量分数分别是0.35,2.76,0.78,4.47 mg·g~(-1),其中二氢丹参酮、隐丹参酮和丹参酮Ⅰ的含量分别比阴干样品增加2.9%(P>0.05),45.3%(P<0.05),34.5%(P<0.05),丹参酮Ⅱ_A的含量减少44.1%(P<0.05)。其相应水溶性成分迷迭香酸及丹酚酸B的含量当采用低温30℃-6 h-高温70℃干制3 h的工艺时达到最高,分别是3.83,55.44 mg·g~(-1),分别比阴干时增加62.3%(P<0.05),109.1%(P<0.05)。变温干制显著影响白花丹参有效成分含量的变化,相对于传统的阴干工艺,低温干制增加白花丹参中水溶性成分的含量,对二氢丹参酮、隐丹参酮、丹参酮Ⅰ等脂溶性成分含量也有明显促进作用,变温干制可以有效缩短干燥过程,为丹参产业化加工提供一定的理论基础。
In this paper, the effects of different temperature-controlled drying conditions on the active constituents of Salvia miltiorrhiza Bunge were studied, which provided the basis for the optimization of commercial drying process of Salvia miltiorrhiza Bunge. In order to ensure the active ingredient content of Radix Salviae Miltiorrhizae, a variety of temperature-dependent drying processes were designed, including low temperature 30 ℃ high temperature 60 ℃, low temperature 30 ℃ high temperature 70 ℃, low temperature 30 ℃ high temperature 80 ℃, low temperature 40 ℃ high temperature 60 ℃, low temperature 40 ℃ high temperature 70 ℃, low temperature of 40 ℃ high temperature of 80 ℃, the use of blast furnace dried Salvia miltiorrhiza variable temperature drying, using HPLC determination of the active ingredient content of Salvia under different dry conditions; SPSS 17.0 statistical software analysis of data. The results showed that the content of DHT, Cryptotanshinone, Tanshinone Ⅰ and Tanshinone Ⅱ_A in Salvia miltiorrhiza was the highest when using low temperature 40 ℃ -6 h and high temperature 80 ℃ for 3 h, respectively. The mass fractions were 0.35, 2.76, 0.78, The contents of dihydrotanshinone, cryptotanshinone and tanshinone I were increased by 2.9% (P> 0.05), 45.3% (P <0.05), 34.5% (P <0.05) , Tanshinone Ⅱ A reduced 44.1% (P <0.05). The contents of rosmarinic acid and salvianolic acid B, the corresponding water-soluble components, reached the highest when dried at 30 ℃ for 6 h and dried at 70 ℃ for 3 h, which were 3.83 and 55.44 mg · g -1 ), Respectively, increased by 62.3% (P <0.05) and 109.1% (P <0.05) than when dry. Compared with the traditional dry-process, the change of water-soluble components in Salvia miltiorrhiza Bge under increasing temperature was significantly affected by temperature-controlled drying, and the contents of lipid-soluble components such as dihydrotanshinone, cryptotanshinone and tanshinone I were also significantly increased Promote the role of variable temperature drying can effectively shorten the drying process for the industrialization of Salvia to provide a theoretical basis.
