Abstract:
OBJECTIVETo establish a method for analyzing the content of total polyphenols in leaves of Jatropha curcas. L.
METHODSGallic acid was used as reference substance, the content of total polyphenols was analyzed Folin-Ciocalteu chromatometry.
RESULTSThere was a good linearity for gallic acid in the range of 0.002-0.010 g.L(-1). The content of total polyphenols in the leaves of Jatropha curcas. L was approximately 6.74% with RSD 0.75%. The sample solution was stable during 10-90 min with RSD 0.28%. The precision RSD was 0.23% and the average recovery 99.85% (n=5).
CONCLUSIONThis method is simple, fast and reproducible.
