UV spectral identification of Fritillaria walujewii / 中草药

ABSTRACT

Object To develop a method for the identification of Fritillaria walujewii Regel by UV spectrum. Methods UV spectrum of the absolute alcoholic extract of F. walujewii was determined and compared with that of four other similarly treated Fritillaria species. Results The UV spectrum of F. walujewii was consistently different with that of the other four species. Conclusion UV spectrum can be used to differentiate F. walujewii from other species of Fritillaria.
