Physicochemical Characterization and Extraction Optimization of Kaempferia parviflora

Abstract

Introduction:  Black ginger (Kaempferia parviflora) is a food crop belonging to the family of Zingiberacea. It is known as Kaempferia parviflora Wall ex. Baker. The other name are Thai ginseng, Thai black ginger, Kali Adrak, Karchaidum. In India, it is mainly cultivated in assam and Mizoram. The compounds of black ginger have shown to possess many medicinal properties, it has anti allergic effects, cardio protective effects, energy enhancement effects, anti-aging effects, anti-inflammatory effects.

Objectives: To assess the physio chemical characteristics and yield percentage in different solvents.

Methods: The physiochemical characteristics of black ginger powder was assessed by using the standard protocol. It includes moisture, ash content, extraction optimization, percentage yield and solubility of black ginger powder. The Soxhlet process were used for extraction at different solvents.

Results: The moisture content was found to be 50.32%. It was found that the moisture and ash content of black ginger was much higher than that of Zingiber officinale. The yield percentage was higher in the ethanol as compared to other solvents.

Conclusions:  It was concluded that the rhizomes of black ginger have higher amount of moisture content as compared to the other variety of ginger (Zingiber officinale). The Soxhlet extraction shows that the yield percentage was higher in ethanol i.e. the solubility was higher in ethanol.
