Establishing Quantitative Model of Naringin in Citrus Grandis Exocarpium by Near Infrared Spectroscopy
摘要
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 ～4 000 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).Conclusion: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.关键词
