摘要
为比较不同生长年限兰州百合的质量,探讨最佳采收期,该文对兰州百合主要成分进行测定分析。兰州百合多糖及总黄酮测定采用紫外分光法;王百合苷A的测定采用高效液相色谱法;氨基酸的测定采用液相色谱-质谱联用法。结果显示,不同生长年限兰州百合所测成分含量差异显著。3年生和4年生兰州百合多糖不符合2020版《中国药典》规定;6年生兰州百合主要成分含量显著高于其他生长年限,5年生次之;生长7年的兰州百合各成分含量均显著下降;且兰州百合不符合理想蛋白质的标准。通过分析得出,若以生产投入和经济效益为标准,应选择5年生兰州百合;若以食用价值和保健功效为标准,应选择6年生兰州百合,若营养价值显著优于其他生长年限。
In order to compare the quality of Lanzhou lily with different growth years and explore the best harvest time,the polysaccharides and total flavonoids of Lanzhou lily were determined by ultraviolet spectrophotometry.Regaloside A and the amino acids were determined by HPLC and LC-MS.The results showed that there were significant differences in the content of components in Lilium davidii from different growth years.The polysaccharides of three-year-old and four-year-old Lilium lancifolium didnot meet the requirements of Chinese Pharmacopoeia 2020.The content of main components of six-year-old Lanzhou lily was significantly higher than that of other growth years,followed by five-year-old.The contents of all components in Lilium davidii grown for 7 years decreased significantly,and Lanzhou lily did not meet the standard of ideal protein.According to the analysis,five-year-old students should be selected according to the production input and economic benefits.However,when edible value and health care effect were taken as the standard,six-year-old Lanzhou lily should be selected because its nutritional value was significantly better than other growth years.
