Abstract

Phenol compound in Piper betle leaves has several pharmacology activities such as antibacteria, antifungi and antioxidant. The pharmacology activities of a herbal drug are influenced by the phytochemistry content, so in order to do a quality determination that provides phytochemistry profile and consistent pharmacology activities, a standardization is required. Fingerprint is the main standard to perform quality control for herbal drug. TLC-spectrophotodensitometry was used as the method in order to provide fingerprint profile of phenol compound. In this experiment, Piper betle leaves samples were extracted by reflux method using ethanol 96% as the solvent. Identification of phenol compound was done using TLC-spectrophotodensitometry with Silica gel 60 F254 as the stationary phase, toluena: ethyl acetate (93:7 v/v) as the mobile phase, FeCl3 and Folin-Ciocalteau as the reagent. The fingerprint profile of phenol compund was shown in Rf value 0,19; 0,42; and 0,62. Positive results of phenol compound are black spot on FeCl3 colour test and dark blue spot  on Folin-Ciocalteau colour test. Maximum wavelength of phenol compound was 283 nm.

Abstract

A Research of the utilization of spectrum shift in confirmation test for barbiturate using TLC-Spectrophotodensitometry has been done. Analyte was analyzed using two mobile phases, that are TD (chloroform: acetone = 80 : 20) and TE (ethyl acetate: methanol: ammonia = 85 : 15 : 5) with Al-TLC Silica 60 GF254 plate as the stationary phase. Afterwards, plate was sprayed with HCl or KOH. The analyzed parameters were hRfc, normal UV-spectrum pattern and its shift. The correlation of spectrum or the shift of UV-spectrum for barbiturate compounds was determined with Wincats program. The analysis of barbiturates which based on hRfc in error window (±7) for TD system and in error window (±11) for TE, still produced hit factor 8-25 compounds. The confirmation test for barbiturates based on hRfc and r ? 0,95, produced hit factor 1-2 compounds. Barbiturate compounds showed spectrum shift in alkali solution, while in acid solution did not happen. However, all four analytes contained identical spectrum shift, therefore the data of these spectrum shift can not be utilized for confirmation test of barbiturate compounds.
