Rapid identification of three Rhodiola species by multi-step IR spectroscopy coupled with multivariate data analysis

Identification of Rhodiola species was the key to ensure the clinical application of Rhodiola, especially in the dried and powdered forms, owing to different Rhodiola species having important differences in the quality and physiological activity of medicinal materials. In this study, multi-step IR spectroscopy combined with multivariate data analysis was employed to establish a on-destructive, fast, and efficient Rhodiola classification method....
