HPTLC DENSITOMETRIC QUANTIFICATION OF SENNOSIDES FROM
Thin Layer Chromatography (TLC) is a sensitive, fast, simple and inexpensive analytical technique. It is a micro technique; as little as 10-9g of material can be detected, although the sample size is from 1 to 100x10-6 g. TLC involves spotting the sample to be analyzed near one end of a sheet of glass or plastic that is coated with a thin layer of an adsorbent. The sheet, which can be the size... Thin layer chromatography (TLC) is one of the most useful, simple, inexpensive, rapid, relatively precise and sensitive methods for separation, identification, and quantification of drugs, poisons, and herbal medicines –.

HPTLC- High Performance Thin Layer Chromatography is a sophisticated and automated form of TLC. Main Difference of HPTLC and TLC - Particle and Pore size of Sorbents. HPTLC TLC
- TLC can be performed manually in easy and inexpensive ways. Therefore it is found in almost all laborato- ries as a convenient tool for simple and rapid separations. As the ex - pectations grow concerning quality and value of an analysis, there are suitable instruments available for all steps of TLC. High-Performance Thin-Layer Chromatography (HPTLC) is the most advanced form of TLC and
- nent on analytical TLC to an Rf of 0.35.9 If several compounds are to be separated which run very close on TLC, adjust the solvent to put the midpoint between the components at Rf = 0.35.
- aliquots and subjected to preparative TLC. The TG were eluted quantitatively with diethyl ether and weighed. FFA in the extract were measured according to the method of Dole and Meinertz (9) and the mean of eight determinations was taken as reference value. The TG concentration of the standard extract (in chloro- form) was adjusted to 156 mg/100 ml by suitable dilu- tion and the FFA
