Abstract
Bacground. Instrumental analysis method give a difference measurement results in determination of content level of active substance in medicinal herb.
Objective.The aim of this study is to compare the level content of phytomelatonin in gren algae extract determinated by spectrophotometry and TCL-densitometry technique.
Methods. the phytomelatonin was extracted from green algae using 90%aethanol. The qualitative Alkaloid screening were done by using Mayer and Dragendroff test. The quantitative determination of phytomelatonin were done spectrophotometrically at 277nm wavelength and using TCL densitometrt techinique with silica gel GF 254 plate and eluated by BAW (n-buthanol:acetic acid: water=12:3:5 v/v). The spots were scanned at 254nm wavelength.
Outcome measured. Phytomelatonin level in aethonolic extract of green algae
Results. The result showed that the content phytomelonin content of green algae level by spectrophotometric technique was 0.22+-0.01 % and 0.88+_0.04% was assayed by TCL-desitometric.
Conclusion. the TCL-desitometry technique gave the higher phytomelatonin of green algae level than specthrophometry technique (p<0.05)
Keywords: Phytomelatonin, green algae, aethanolic exctract, spectrophotometry, TCL-densitometry.
