微射流技术提取虎杖中有效成分的研究

Study on Extraction of Active Components from Polygonum Cuspidatum by Micro-jet Technology

目的研究微射流技术对虎杖有效成分的提取效果。方法以虎杖中总黄酮、总多糖、虎杖苷、白藜芦醇和大黄素等有效成分含量为指标,评价微射流技术和煎煮法对上述成分的提取效果。结果微射流提取技术对比煎煮法对虎杖中总黄酮和总多糖的提取差异不大(总黄酮1.2倍,总多糖1.3倍);但对虎杖苷、白藜芦醇和大黄素的提取差异较大(虎杖苷3.5倍,白藜芦醇和大黄素在煎煮法中未被提取出来)。结论微射流技术提取虎杖药材中虎杖苷、白藜芦醇和大黄素具有明显的技术优势。

Objective：To investigate the extraction effect of micro-jet technology on the active components of polygonum cuspidatum.Method：The content of active ingredients such as total flavonoids,total polysaccharide,polydatin,resveratrol and emodin in polygonum cuspidatum were used as indexes to evaluate the extraction effect of micro-jet technology and decoction on the above components.Result：There was no significant difference in the extraction of total flavonoids and total polysaccharides（total flavonoids 1.2 times,total polysaccharides 1.3 times）,but there was significant difference in the extraction of polydatin,resveratrol and emodin（polydatin 3.5 times,resveratrol and emodin were not extracted in the decoction method）.Conclusion：Extraction of polydatin,resveratrol and emodin from polygonum cuspidatum by micro-jet technology has obvious technical advantages.
