well as spotting the standard spinach extract. A beaker was used with the developing solvent‚ filter paper‚ and TLC plate inside and a watch glass over top of the beaker to perform the thin layer chromatography. After the solvent front (30% ethyl acetate in hexane) reached about an inch from the top‚ the TLC plate was removed from the beaker and the developing spots were marked. After implementing the column and thin layer chromatography‚ the Rf value for component one was .95‚ for component two it

The column fractions were collected in 25 ml test tubes. In that‚ fraction number 271-275th showed identical clear spot which were loaded on the activated silica gel TLC plates (20 cm × 20 cm). The plates were developed using methanol: ethyl acetate (60:40) solvent system. The single spot was located by exposing the plate to iodine fumes. Thus‚ it may indicate the presence of single

3. Results and discussion 3.1 Nutritional analysis In the present study‚ the potential benefits were shown by nutritional attributes of dried bathua (Table1). Moisture content and dry matter analysis‚ reporting during nutritional analysis is very important because it directly affects the nutritional content of vegetable. The moisture content was quite low (5.06%) which may be advantageous in view of increasing the sample’s shelf life. Bathua was found to be rich in carbohydrates (40.84%). There

Nitration of Methyl Benzoate Purpose: The purpose of this experiment was to synthesize methyl m-Nitrobenzoate from methyl benzoate‚ concentrated HNO3‚ and concentrated H2 SO4 by an electrophilic substitution reaction. The H2 SO4 and the HNO3 were initially combined to form nitronium ion which was then used as an electrophile in the reaction. Crystals that were collected after the formation of the methyl m-Nitrobenzoate were collected by vacuum filtration and the product was isolated and purified
