Flavonoids of Oenothera (Onagraceae) in Taiwan

臺灣的月見草屬植物(柳葉菜科)類黃素化合物之分類學研究

摘要


月見草屬植物目前在臺灣發現有四種,即月見草(Oenothera tetraptera Cav.)、裂葉月見草(O. laciniata Hill)以及O. glazioviana Mich.,O. stricta Ledeb,ex Link.本文分析了這四種植物葉中所舍之類黃素色素,發現總共有10種化合物,其化合物組成因種而異。另外比對了Howard等氏1972年之報告,發現本省之後兩種月見草與其他地區之各該種植物的葉黃素組成,有著明顯的族群間差異存在。

A survey of foliar flavonoids in four species of Oenothera (Onagraceae) from Taiwan revealed ten flavonol-O-glycosides based on kaempferol, quercetin, and myricetin. Each species can be distinguished by its own characteristic complement of these compounds. Infraspecific variation in flavonoid profile is apparent in O. stricta and O. tetraptera when literature is consulted and compared. Our analyses on the flavonoids of O. glazioviana and O. laciniata represent first reports.
