Abstract :

The rhizomes of the Zingiberaceae family are a vegetable widely used in many Asian countries and their medicinal functions have been oadly discussed and accepted in many traditional recipes. In this study, three medicinal plants of Zingiberaceae family were collected and analysed for their functional properties. The methanolic extraction of three medicinal plant species showed the positive results for the presence of phytochemicals i.e. alkaloids, proteins, carbohydrates, phenols and tannins, flavonoids, saponin, glycosides, steroid and terpenoids. Methanolic extracts of the plants were also analysed for their total phenol compounds and total flavonoid content. The results showed that the total phenol compounds of Curcuma caesia was found to be highest among the three medicinal plants of Zingiberaceae and its value is 62 ± 0.2 mg/g whereas the total phenolic content of Hedychium coronarium and Curcuma angustifolia were found to be 26.22 ± 0.5 mg/g and 20.05 ± 0.5 mg/g respectively. Total flavonoid contents among the three medicinal plants of Zingiberaceae was found to be highest in Curcuma caesia and its value was found to be 30±0.007 mg/g.
