摘　　要：以胡椒内酰胺、芦丁和葡萄糖为指标,采用紫外分光光度法比较真空冷冻干燥法和自然干燥法对鱼腥草中多糖、黄酮、生物碱含量的影响,结果表明,真空冷冻干燥法加工的鱼腥草中多糖、黄酮、生物碱的含量高于自然干燥法。说明真空冷冻干燥法能较大限度地保证鱼腥草的药效。The content of polysaccharide,flavonoid and alkaloids were determined with piperolactam,rutin and glucose as mark by UV-2450,to compare the quality of Houttuynia cordata between the vacuum freezing and natural drying.The results showed that the content of polysaccharide,flavonoid and alkaloids of Houttuynia cordata processed by vacuum freezing drying was significantly higher than those by natural drying.The method of vacuum freezing drying can guarantee the quality of Houttuynia cordata.
