Blady grass (Imperata cylindrica Beauv.), or ya-kha in Thai, is a species of grass in family
Poaceae and used as a diuretic. According to the policy of the Ministry of Public Health on pro-
moting the use of Thai herbal medicines, the standardization of all herbal products is necessary.
The aim of this study was to create quality control guidelines for blady grass roots. Sixteen samples
of blady grass roots were assessed for their physicochemical properties, namely moisture content,
total ash, acid insoluble ash, water extract, ethanol extract were determined. The results showed
that the average contents of moisture, total ash, acid insoluble ash, water extract, and ethanol
extract were 6.47±1.56%, 5.87±0.99%, 3.26±1.33%, 23.92±6.66%, and 23.82±7.01%, respectively.
Key words: physicochemical property, blady grass root, Imperata cylindrica Beauv.
