FTIR fingerprinting combined with chemometrics of Guiera senegalensis leaf powder

Guiera senegalensis is a shrub that grows up to a height of 3 to 5 m and has tremendous medicinal properties. However, there is difficulty in the identification of medicinal plants leading to substitution of one plant for another. This problem can be addressed by establishing fingerprints of the medicinal plants. The aim of this research is to establish FTIR fingerprint of G. senegalensis leave. G. senegalensis leave were collected from the wild in Jigawa, Kaduna and Zamfara states, shade dried and size reduced. Samples (2 mg) were analysed in triplicate using Agilent technologies FTIR Carry 630 in the mid-IR region 4000-650 cm-1 at resolution 8 cm-1 with 16 scans. The level of similarity and differences was determined by Chemometrics using similarity and discriminant analysis. The level of differences between the samples was insignificant (p
