摘要
为了揭示采收期对杭白菊4个主栽品种主要功效成分的影响,确定最佳采收期,采集杭白菊4个主栽品种花蕾、胎菊、幼菊、全菊4个时期16个样品,采用紫外-可见分光光度计法测定总黄酮含量;以反相高效液相色谱法测定绿原酸、木犀草苷、3,5-O-双咖啡酰基奎宁酸含量。结果表明杭白菊4个主栽品种不同采收期采收对其主要功效成分有显著影响,总黄酮和绿原酸含量在花蕾期最高,胎菊期次之;木犀草苷含量胎菊期最高,幼菊期次之;3,5-O-双咖啡酰基奎宁酸含量胎菊期最高,花蕾期次之;4个品种单花质量从花蕾期到全菊期均显著增加,全菊最高。综合功效成分与采收期的关系,杭白菊4个主栽品种均在胎菊期采收最佳。
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-β-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-β-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.
