Abstract

A research has been done to synthesize hexa-p-tert-butylhexaestercalix[6]arene using p-tert-butylcalix[6]arene as a starting material. The synthesis was carried out by esterifying p-tert-butylcalix[6]arene. Synthesis products were identified and characterized by melting point, TLC, FTIR, 1H-NMR, and 13C-NMR spectrometers. Synthesis products was obtained a white solid powder (68.45% recovery), melting point 349-351 °C, TLC (SiO2, ethanol: ethyl acetate = 1: 1 v/v, Rf = 0.90). The results of the analysis  of synthesis products with FTIR, 1H-NMR, and  13C-NMR spectrometer showed that the synthesis products compound is 5, 11, 17, 23, 29, 35-hexakis (p-tert-butyl)-37, 38, 39, 40, 41, 42-hexakis (ethoxy-carbonylmethoxy) calix[6]arene.

Abstract

The antioxidant activity test of methanol extracts of the leaves nasty shard Strobilanthes crispus has been done. This study aims to test the phytochemical and antioxidant activity of methanol extracts of the leaves nasty shard Strobilanthes crispus. The leaves nasty shard are macerated with methanol for 3x24 hours. Further methanol extract was tested phytochemically and antioxidant activity by DPPH method (1,1-Diphenyl-2-picrylhydrazil). The result of phytochemical test showed that the methanol extract of the leaves nasty shard Strobilanthes crispus contain secondary metabolites of alkaloids, flavonoids, and saponins. The result of antioxidant activity test showed that the methanol extract of the leaves nasty shard Strobilanthes crispus have antioxidant activity with IC50 of 100,363 ppm.

Abstract

N-p-Methylbenzyl-p-coumaramide has been synthesized from p-coumaric acid. The purpose of this study was to synthesize N-p-methylbenzyl-p-coumaramide compounds from p-coumaric acid. The N-p-methylbenzyl-p-coumaramide target compound was obtained by direct conversion method using a orthoboric acid catalyst. Target compounds were identified and characterized by melting point, TLC test, FTIR, 1H-NMR, and 13C-NMR spectrometer. The results showed that N-p-methylbenzyl-p-coumaramide compound obtained was white solid (yield 75.83%) with melting point 156-158 oC and TLC (SiO2, n-hexane : chloroform = 5: 3 v/v, Rf = 0.37).

Abstract

N-Benzenesulfonyl-p-Coumaramide has been synthesized from  p-qumarid acid. This research aimed to synthesized  N-Benzenesulfonyl-p-Coumaramidefrom p-qumarid acid. Targeted coumpound obtained  from two steps reaction. Whice were amidation and asilation. Shynthesized product was identified and characterized by melting point, thing Layer Chromatography analysis, FTIR Spectrhophotometer,  1H-NMR, dan 13C-NMR. The result showed the obtained N-Benzenesulfonyl-p-Coumaramide was white solid ( yield 78.58 %) with melting point was 145-147 oC  and KLT (SiO2, n-hexane : cloroform = 6 : 4 v/v, Rf = 0.45).
