摘要： The contents of individual and total glucosinolate in Chinese kale (Brassica albograbra Bailey) were determined and analyzed using near-infrared spectroscopy. The near infrared calibration mathematics model between total glucosinolate contents and spectral measurement was established based on modified partial least squares. The coefficient of determination of the cross-validation (1-VR), coefficient of determination in prediction and ratio of the standard deviation to the standard error of the cross-validation of the near-infrared spectroscopy calibration equations were 0.92, 0.91, and 3.59 for total glucosinolates; 0.87, 0.82, and 2.78 for gluconapin; 0.93, 0.93, and 3.84 for glucobrassicin; and 0.86, 0.90, and 3.70 for neoglucobrassicin. Near-infrared spectroscopy showed high accuracy in predetermining individual and total glucosinolate contents in Chinese kale.
