AbstractAn aqueous extract of Gynostemma pentaphyllum (Thunb.)Makino aerial parts demonstrates its potential as an herbal extract for health products. Gypenosides, Dammarane-type saponins, are major constituents with various biological activities such as antitumor, antilipemic and anti-inflammatory activities. In this study, the evaluation of G. pentaphyllum aqueous extract was performed in 15 samples of crude drugs purchased from different cultivated sources in the northern part of Thailand. The chemical specification for the aqueous extract of G. pentaphyllum was established as following: total ash content was not more than 20.0%w/w, acid-insoluble ash content was not more than 1.0%w/w, moisture content was not more than 9.0%w/w and total crude saponins content was not less than 22.0%w/w. Moreover, the chemical identification of the extract both by color test and Thin Layer Chromatographic analysis was also reported.
