Plant extracts from natural sources are an excellent choice for food additives and antioxidants. In this study, the active components of Tulipa edulis were extracted analysed, their antioxidant capacity was measured. Then, crude extract mixture separated purified using a Sephadex LH-20 gel, activity products determined. Human umbilical vein endothelial HUVEC cells treated with 35 mmol/L ...

Tulip (Tulipa gesneriana L.) is a bulbous plant species that requires a period of low temperature for proper growth and flowering. The mechanism of sensing the low temperature period is unknown. The study presented in this paper shows that the essential developmental change in tulip bulbs during cold treatment is an increase in sensitivity to the phytohormone auxin. This is demonstrated using a...

To utilize scent as an added value of cut tulip flowers, it is necessary to reveal how the changes during anthesis. This study investigated daily in emission flowers under different temperatures (13℃, 18℃, and 23℃), using Tulipa ‘Niigata 13 go.’ At 23℃, total was high decreased with tepal senescence. The emissions at 18℃ increased later than those 23°C. lowest temperature (13°C) resulted overal...

Tulips are bulbous geophytes that have considerable commercial value worldwide. This genus primarily originated in the Tien Shan and Pamir-Alai mountain ranges, which surround Ferghana Valley. The Valley is home to five sections of Tulipa L, represented by 23 taxa (22 species). However, there a lack detailed information about distribution species natural geographic area Therefore, address this ...
