leaves extract also reported has antibacterial and antidiabetic activities. It is essential to determine its specific and non specific parameters in assesing the quality and safety.
The samples collected from three different perferctures. Grounded samples were macerated with ethanol. The extracts were subjected to determine its characteristic parameters. Parameter of quality for the extracts consisted of water content, ethanol-extractive, water-extractive, loss on drying, total ash, acid-insoluble ash, solvent residue and heavy metal content. Phytochemical identification showed that the ex-tract contains flanovoid, tannin, glycosides, and saponin. TLC chromatogram using chloroform-methanol-water (80:12:2) as mobile phase, exhibited 4 spots after sprayed with iron(III) chloride. Total phenolic was determined spectrophotometrically using
Folin Ciocalteu reagent, gave 0.35-8.24% total phenolic as gallic acid.
Key words: Folin Ciocalteu, phenolic compounds,  TLC chromatogram, standard-ization, Tamaridus indica.
