| Summary: | The isolation and identification of chemical compounds of the rhizome of .Pakisnaga (Pol_ytodium Feei Mett., Polypodiaceae) were carried out. The preleminaryr chemical study showed the presence of tanin, flavonoid and triterpenoid. A pentacyclic triterpene which was supposed to be arbor-7-ens was isolated from the petroleum ether extract and identified by UV and IR spectrophotometry, mass spectrometry, RMN spectrometry and CHNS analysis. From the n-butanol extract a:flavonoid could be isolated which was assumed to be a glycoside of ._kaempferol derivative with two sugars. Calcium, sodium and kalium were found in the ash of the rhizome. |
