title: [Establishing quantitative model of naringin in citrus Grandis Exocarpium by near infrared spectroscopy].
abstract: OBJECTIVE
  To establish the quantitative model of naringin in Citrus Grandis Exocarpium by near infrared reflectance spectroscopy(NIRS).
  
  
  METHODS
  NIRSs of 54 Citrus Grandis Exocarpium samples were collected and pretreated by TQ Analyst 8.0 software with first derivative + Norris filter. The wavebands in 10,000-4000 cm(-1) were collected and 9 numbers of factors were used. The calibration model was built with partial least squares (PLS).
  
  
  RESULTS
  The quantitative calibration model had good correlation coefficients (r = 0.9927) and low root mean square error of calibration (RMSEC = 0.0746). Root mean square error of prediction (RMSEP) was 0.282. The average rate of recovery of validation was 101.65% (n = 9).
  
  
  CONCLUSIONS
  The quantitative calibration model is trustworthy and it can be used to predict naringin in Citrus Grandis Exocarpium accurately. This simple, fast and non-destructive advantages of NIRS can be used for quality control and exploitation of Citrus Grandis Exocarpium.
