AI Technical Summary

Technical Problem

Existing technologies using near-infrared spectroscopy to evaluate the quality of complex compound extracts of Uncaria rhynchophylla and Clematis chinensis for gout relief suffer from problems such as spectral interference and insufficient predictive stability, leading to inaccurate predictions of the content of key quality markers.

Method used

The spatial density distribution structure of spectral feature points is constructed. By calculating the distribution density function of spectral feature points in multidimensional space, the characteristic absorption peaks of rhynchophylline, isorhynchophylline, and clematisin are determined, spectral response calibration coefficients are generated, and the partial least squares quantitative model is optimized. The quality grade is determined by combining spectral similarity analysis.

Benefits of technology

It improves the reliability of quality marker content prediction and the adaptability of the model, and enables rapid and non-destructive testing of compound extract quality, ensuring stable compliance of product efficacy components and batch consistency.
