From: Chemical compositions, chromatographic fingerprints and antioxidant activities of Citri Exocarpium Rubrum (Juhong)

Analyte Calibration curvea R 2 Linear range (mg/L) LODb (ng/mL) LOQc (ng/mL)
1 y = 3.0149x  21.812 0.9994 31.20–499.20 418.8 128.6
2 y = 41.396x  4.1898 0.9995 0.75–11.94 6.8 24.7

  1. 1 Hesperidin, 2 Nobiletin, 3 Tangeretin
  2. a y is the peak area in UV chromatograms detected in 330 nm, x is the concentration (mg/L) of the analyte
  3. bLOD refers to the limit of detection, s/n = 3
  4. cLOQ refers to the limit of quantification, s/n = 10
