Abstract
Abstract
Ginger rhizome (Zingiber officinale Roscoe) is a widely used medicinal plant and
spice since antiquity. It has many biological activities and is commonly used as a home
remedy herbal tea. Hence, it’s usually subjected to adulteration. Besides, clinical
investigations involved the study of ginger’s biological activity showed mixed and variable
results. This may be due to the lack of appropiate method of standardization. Thus, an
adequate method is required for its quality control. This study investigated the use of
different spectroscopic techniques for complete fingerprint analysis of ginger with further
chemometric analysis as a successful model for the discrimination of different ginger
samples according to their geographical origin. . In addition, a stability study is performed
on stored ginger for the detection of storage effect on the stability of its main active
constituents. The study involved the use of 22 authentic ginger samples obtained from
different geographical origins and 39 samples obtained from different regions of the
Egyptian market. Results showed that UV spectroscopy and HPLC analysis coupled with
chemometrics can be used successfully for discrimination of ginger according to its
geographical origin. Also, storage of ginger greatly affect its stability and concentration of
its pungent principles decrease remarkably especially when stored in powder form.
