Precarthamin, a yellow precursor of carthamin, was efficiently isolated from the yellow petals of safflower (Carthamus tinctorius L. ) with Sephadex LH-20 column chromatography and preparative HPLC, and identified with UV-vis and NMR spectrometry. The UV-vis spectrum of precarthamin showed lambda(max) of 238 and 406 nm in MeOH. The molar extinction coefficients of precarthamin at 406 nm in MeOH...

Safflower, an important oil plant, has been cultivated for about 3000 years. Due to the fact that it is used as a raw material in many sectors, safflower examined various studies. This study was carried out laboratories of Department Biosystem Engineering and Central Laboratory Application Research Center, Faculty Agriculture, Bingol University between 2020 2021. In study, saturated fat content...

Hydroxysafflor yellow A (HSYA) is an effective ingredient of the Chinese herb Carthamus tinctorius L, which has high water solubility and low oral bioavailability. This research aims to develop a hydrophobic nanoparticle that can enhance the oral absorption of HSYA. Transmission electron microscopy and freeze-fracture replication transmission election microscopy showed that the HSYA nanoparticl...
