Carthamus tinctorius 'Ken-ba'
fresh
Sample note
Cultivar Ken-ba was grown in the field of Hirosaki University in Japan. The capitula were harvested when tubular florets had just appeared outside the involucres. Only tubular florets were collected. Ken-ba is a wild type cultivar the petals of which look orange yellow. For flavonoid analysis, florets (3g9 were hoogenized and extracted with cold 1 % TFA-MeOH (2 mL x 3).
Extraction solvents
1 % TFA-MeOH

Extraction temperature
4 °C
Extract drying method
evaporation in vacuo
Analysis solvents
methanol:water (1:1, v7v)
Detection note
White amorphous powder was obtained.
