UPLC-Q-TOF-MS-based metabolomics was applied to depict the variable chemotaxonomic markers and elucidate the metabolic mechanism of Citrus TCMs from different species and at different ripening(More)
This study is to establish an HPLC fingerprint by HPLC-DAD method and simultaneous quantitative analysis of 17 components of 18 batches of Citrus aurantium and 10 batches of C. sinensis. The separation was performed on an Agilent Poroshell 120 SB-C₁₈ (4.6 mm×100 mm,2.7 μm) column with the gradient elution of methanol-0.1% formic acid water, the flow was 0.6(More)
Four types of dust from dormitories, offices, hotels and roads in Beijing were collected and fractionated into 9 fractions, respectively. Totally 36 samples were obtained and analyzed for heavy metals including Cu, Zn, Cr, Pb, Cd and Ni. Particle size distributions of those heavy metals in these four types of dust were investigated and the influencing(More)
