- 論文の詳細を見る
An extract of cotyledons of Pharbitis nil, which had been exposed to short-day conditions, was tested for flower-promoting activity in a shoot-tip assay system in vitro. The crude extract had no flower-promoting activity, however, after partitioning of the crude extract with dichloromethane, the resulting aqueous fraction had flower-promoting activity. This activity was separated into two fractions by column chromatography on Toyopearl HW-40. One active fraction was identified as dihydrokaempferol-7-O-β-D-glucoside (DHK-glc). This compound exhibited flower-promoting activity at the extremely low concentration of 4.4×10^<-9> M.
