To reveal the effects of harvesting stage on the functional constituents of four kinds of Hangbaiju and determine the best harvesting stage. Sixteen samples of Hualei, Taiju, Youju, Quanju were collected from Zhejiang Tongxiang. The content of total flavonoids were determined by UV spectrophotometry. Chlorogenic acid, lutelin-7-O-beta-D-glucoside and 3,5-O-discaffeoylquinc acid were analyzed by HPLC. The results showed that the effect of harvesting stage on the functional constituents of four kinds of Hangbaiju was significant. The contents of total flavonoids and chlorogenic acid reached maximum at the Hualei stage, and next was Taiju. The highest content of lutelin-7-O-beta-D-glucoside and 3,5-O-discaffeoylquinc acid was found in samples of Taiju. The yield of the four kinds of Hangbaiju increased obviously as the collection time deferred. Considering the functional constituents, yield and harvesting stage, the stage of Taiju is the best harvesting time.
为揭示采收期对4种杭白菊功能成分的影响并确定最佳采收期。从浙江桐乡采集了16份花雷、胎菊、尤菊、全菊样品。采用紫外分光光度法测定总黄酮含量。采用高效液相色谱法分析绿原酸、木犀草素-7-O-β-D-葡萄糖苷和3,5-O-二咖啡酰奎宁酸。结果表明，采收期对4种杭白菊功能成分的影响显著。总黄酮和绿原酸含量在花雷期达到最高，其次是胎菊。胎菊样品中木犀草素-7-O-β-D-葡萄糖苷和3,5-O-二咖啡酰奎宁酸含量最高。4种杭白菊的产量随着采收时间的推迟而明显增加。综合考虑功能成分、产量和采收期，胎菊期是最佳采收时间。
