STD

True

TLC

False

UV/Vis detector description

Mass spectrometer description

UHPLC-ESI-QTOF-MS, quadrupole time-of-flight

Organism

Carthamus lanatus  L.

wild

dried, frozen

Sample note

The material (Accession Number W6 16791) were obtained from USDA National Plant Germplasm system. The seeds were planted and cultivated in a greenhouse at 18-25 °C located at the National Institute of Agricultural Sciences, Jeonju, Korea. The collecting (by hand) of of florets of early stage samples started approximately 12 weeks after seed planting. These EARLY STAGE flower samples were collected before the beginning of the flowering, when the upper portion of the florets were about to emerge through the bracts. The samples wer snap-frozen using liquid nitrogen, the freeze--dried and stored at -80 ° until further processing. Visually seen, there was not yet much color in flowers, only white and light yellow hues. The leaf shape was lanceolate.

The material (Accession Number W6 16791) were obtained from USDA National Plant Germplasm system. The seeds were planted and cultivated in a greenhouse at 18-25 °C located at the National Institute of Agricultural Sciences, Jeonju, Korea.These MIDDLE STAGE flower samples were collected when flowering was considered complete, i.e. more than 90 % of the florets were open. The florets were yellow and the pistils became orange as the development proceeded, and the colour started to change gradually yellos/red.
