丹红注射液生产过程中丹参固体废弃物的资源性成分分析及其转化机制研究

Resource components analysis on Salvia miltiorrhiza residues in production process of Danhong Injection and its transformation mechanism

目的分析评价丹红注射液生产过程中产生的丹参固体废弃物丹参酮类及残留丹酚酸类资源性化学成分,并研究资源性化学成分转化机制及其废弃物的循环利用价值和资源化途径,以期为丹参固体废弃物的资源化利用提供科学依据。方法采用甲醇超声法提取丹参药材及其药渣中的资源性化学成分;用HPLC-PDA法对其进行定量分析与测定,BDS HYPERSIL C18色谱柱(250 mm×4.6 mm,5μm);柱温30℃;体积流量1 ml/min;以流动相乙腈-0.1%甲酸水进行梯度洗脱。结果丹红注射液生产过程中产生的丹参固体废弃物中丹参酮类成分与丹参药材相比,几乎未被利用而残留于固体药渣中;尚残留一定量的丹酚酸类成分;水提后丹参药渣中丹酚酸A、原儿茶醛的量高于丹参药材。结论丹红注射液生产过程中生产的丹参固体废弃物中丹参酮类资源性化学成分值得进一步开发利用。

Objective To analyze the resource components（tanshinones and salvianolic acids） in Salvia miltiorrhiza residues in production process of Danhong Injection, explore the constituents transformation mechanism, and discover the resource utilization pathway for S. miltiorrhiza residues. Methods The chemical constituents in S. miltiorrhiza and S. miltiorrhiza residues were extracted by methanol ultrasonic method. The HPLC-PDA analysis was carried out on a BDS HYPERSIL C18（250 mm × 4.6 mm, 5 μm） column with acetonitrile-0.1 % formic acid solution as mobile phase for gradient elution. The flow rate was 1.0 m L/min, the column temperature was maintained at 30 ℃. Then the residues resource utilization was further explored based on the research results and previous work. Results The tanshinone components were virtually unused and remained in the residues during the production process of Danhong Injection. The contents of salvianolic acid A and protocatechuic aldehyde in the residues are higher than those in the salvia herbs. Conclusion The tanshinones in S. miltiorrhiza residues are worthy of further development and utilization during the Danhong Injection production process. It provides a main basis for the resource utilization and development of S. miltiorrhiza residues.
