Characterization of TDNPs. A TDNPs were isolated and purified by sucrose gradient ultracentrifugation, band 1 from 8%/30% interface was named TDNPs 1, and band 2 from 30%/45% interface was named TDNPs 2. B Transmission Electron Microscopy (TEM) to characterize the morphology and size. C TDNPs were also identified by Atomic Force Microscopy (AFM). D Yields of TDNPs 1 and TDNPs 2 from turmeric were calculated and compared (n = 5). E Putative lipid species between TDNPs 1 and TDNPs 2 were compared
