In fact, the term myristic acid comes from Myristica fragrans which is the scientific name for the most common commercially available species of nutmeg. Treatment is supportive, with the use of antipsychotic therapy when necessary.
We used the melting points to determine if we isolated a pure sample from both trimyristin and myristic acid.
To the round-bottomed flask, add the calculated volume of a 0. Rani P, Khullar N. Are you sure you want to delete this answer? Following the outcome of trimyristin, hydrolysis was performed to obtain myristic acid.
What did you see? During the extraction of trimyristin from nutmeg, two students were given different samples of nutmeg.
This melting point is higher than the melting point of the first recrystallized product because it is purer due to the additional recrystallization.
Alternately, remove the petroleum ether by rotary evaporation. Abuse of nutmeg Myristica fragrans Houtt. However, acetone is an organic solvent that can more easily dissolve trimyristin at a higher temperature than diethyl ether.
It has been suggested that the other components do not themselves contribute to the psychotropic activity, but promote absorption of myristicin by irritating the gastrointestinal tract.
Anggakusuma, Yanti, Hwang JK. Morton, Brown University 2. The hydrolysis is typically carried out by refluxing the ester in an aqueous base, such as KOH or NaOH, so the resulting myristic acid is produced in its salt form, a myristate. Extraction of Trimyristin from Nutmeg Weighed down by the sudden spurt in practical sessions at college?
Hydrolysis of one mole of a triglyceride affords one mole of 1,2,3-propanetriol glycerin and 3 moles of fatty acids, which are carboxylic acids containing the functional group at the end of a long alkyl chain.
Antifungal activity of some essential oils. The percent yields for all products were lower than expected. Comparison of effects of extract of Myristica fragrans and verapamil on the volume and acidity of carbachol induced gastric secretion in fasting rabbits.The extraction of trimyristin from nutmeg is a classic experiment.
Usually diethyl ether is used as the extraction solvent, but I tried using a different method.
To a ml conical flask, I. ORGO Experiment #2 Extraction of Trimyristin from Nutmeg. STUDY. PLAY. Heating under reflux. A familiar example is the HOT-WATER EXTRACTION OF CAFFEINE and the various OILS THAT CONSITUTE THE FLAVORS OF FRESHLY BREWED COFFEE AND TEA from beans and leaves.
What is the experimental/actual yield of trimyristin from solid/liquid extraction? b. If you utilized a saponification (hydrolysis) reaction to generate myristic acid and glycerol from the recovered trimyristin (see hydrolysis reaction scheme below), what would be your theoretical yield of glycerol (example calculation provided below)?
Extraction and Purification of Terpenes from Nutmeg (myristica fragrans) Essam F. Al-Jumaily and Maytham H.
A. Al-Amiry Department of Biotechnology, Genetic Enginerring and Biotechnology Institute for Post Graduate, Baghdad University, Baghdad-Iraq.
Abstract. Extraction, distillation, recrystallization, and chromatography are used the techniques that are used to isolate and purify chemical compounds from natural sources. The extraction of nutmeg seed to isolate trimyristin was performed in this lab.
Trimyristin consists of long saturated hydrocarbon chains and it is relatively nonpolar. Thus using a relatively nonpolar solvent, trimyristin can be easily extracted by the concept of "like dissolves like".Download
