摘要
为了更好地指导雪菊生产,分别对雪菊花蕾、小花、中花和大花中的活性物质总黄酮、绿原酸、茶多酚、总糖、总氨基酸以及微量元素的含量进行了室内测定。结果表明:大花百粒干重最大为7.425g,小花总黄酮和总糖含量最高,分别为15.845%和19.715%,花蕾期绿原酸、总氨基酸、茶多酚含量最高,分别为6.594、9.900、14.337mg·g-1。Ca、Zn、Cu的含量均在花蕾期最高,分别为6445.3、84.12、35.19mg·g^(-1),Mg和Mn在小花期含量最高,Fe的含量在大花期最高,花蕾期最低。花蕾期和小花期活性物质和微量元素含量相对较高,可以确定为雪菊最佳采收期。
In order to better guide the Coreopsis tinctoria production, contents of the active substances total fla- vonoids,chlorogenic acid,tea polyphenol, total sugar, total amino acid and trace element of flower bud, floret, middle flower and big flower of Coreopsis tinetoria were respectively determinated of indoor. The results showed that the big flower hundred flower dry weight was up to 7. 425 g,floret flavonoids and total sugar con- tent in the highest, 15. 845 % and 19. 715%, respectively, the bud period of chlorogenic acid, total amino acid, tea polyphenol content was the highest,6. 594 mg,9. 900 mg ·g^-1 ,14. 337 mg ·g^-1. The content of Ca,Zn and Cu in bud stage reached the highest by 6 445.3 rag,84.12 mg·g^-1 ,35.19 mg·g^-1 ,Mg and Mn in floret period reached the highest levels, the content of Fe in large flowering was the highest,lowest bud stage. Bud stage and flower stage active substances and trace elements content was relatively high, could be identified as Coreopsis tinctoria best harvest time.
