How to Prepare Kava Kava Root Powder?

6 effective active components of kavalactones were extracted from kava roots and plant stems using different organic solvents. The results showed that ethanol had the highest extraction efficiency for kavalactone. The following is the extraction flow chart of Kava Kava Root Powder:

Different solvent extraction affects active ingredient variation.

In Tonga and Fiji, kava roots and rhizomes are mixed with cold water or cocoa milk, ground into a paste, and then strained to drink.

Polynesians use water and low-concentration ethanol aqueous solutions to extract kava piperonolide or make tinctures, which have low extraction efficiency and relatively low active ingredients.

Kava pepper extract prepared in Germany can be obtained with a high concentration of ethanol solution containing about 30% kava lactone. Or use a highly concentrated acetone solution to obtain up to 70% kavalactone. High concentration ethanol and acetone solution enhanced the extraction ratio of kavalactone, and the extraction efficiency was related to solvent and temperature.

China has carried out a small test on the extraction and separation of kava medicinal components and the processing of kava products on kava rhizomes. The prepared kava lactone extract has a purity of 72.13%.

Summary

At present, the extraction of total lactones from kava with ethanol solvent is the best extraction process. The total lactone content and extraction rate obtained by this method are relatively high.
