Evaluation of medicinal constituent (Gingerol)‎ in Iraq cultivated ginger

Abstract EN

The evaluation of gingerol as medical entities in Iraq and Jamaica cultivated ginger was done in this experiment.

Two different types of cultivated ginger (Iraq and Jamaica) of the same species (Zingiber officinal) were extracted to achieve the subject of this study.

Extraction was performed by two different stages: the first stage preparative and extraction.

Harvested ginger was prepared for extraction by wash, denotation, drying, grinding, and extracting by acetone under heating.

The second stage is separation by two steps via TLC and HPLC.

The quality and quantity of oleoresin and gingerol in each step of separation were checked by spots diameter and RF value of spot migration in TLC ginger compounds and quality of whole extract and number of peak in HPLC as well as quantity of gingerol after HPLC separation was done for both Iraqi and Jamaica ginger.

The results of comparison between cultivated ginger of Iraq and Jamaica showed significant decrease (P<0.05) in quantity of extracts and spot diameter of oleoresin where as no significant change (P<0.05) in gingerol quantities by HPLC separation was found in Iraqi species.

These results showed no effect of different cultivation conditions of both peak Jamaica and Iraq species on medical entities of ginger content of gingerol.
