Determination of Pure Carotene in Plant Tissue - A Rapid Chromatographic Method
RESEARCH project at this laboratory involved the A accurate determination of the carotene content of many samples of fresh and dehydrated vegetable products. (Carotene referred to in this paper includes both alphaand betacarotene, in most cases approximately 10 per cent alpha and 90 per cent beta.) The methods commonly used a t present for the determination of carotene in plant materials depend...
متن کاملpH DETERMINATION IN PLANT TISSUE.
In a recent investigation1 a procedure was found that permitted fairly accurate determinations of the pH of soils of low moisture percentages. One of the essentials of the method was the use of a horn spoon in spreading the moisture or soil films uniformly throughout the rather dry soil mass. When plant tissue is finely cut in a grinder, relatively few of the cells are actually opened. The impo...
متن کاملColorimetric Determination of Serum
In the past few years there has been renewed interest in the study of serum cholinesterase in various disease states, particularly those affecting the liver. Recently, a colorimetric method for the determination of this enzyme in the serum was reported by Ravin, Tsou, and Seligman (1). Their method, simple to perform, is as accurate as the gastrometric technique and more specific than the elect...
متن کاملDetermination of Carotene in Sweet Potatoes.
The determination of carotene in fresh plant tissue is complicated by the presence of large amounts of water. The tissue must be dehydrated before the carotenoids can be extracted with fat solvents. This has been accomplished in the past by the addition of acetone or ethanol with a fat solvent such as Skellysolve B (8, 5). These methods employ a Waring blendor for disintegrating the tissue in t...
متن کاملdetermination of maximal singularity free zones in the workspace of parallel manipulator
due to the limiting workspace of parallel manipulator and regarding to finding the trajectory planning of singularity free at workspace is difficult, so finding a best solution that can develop a technique to determine the singularity-free zones in the workspace of parallel manipulators is highly important. in this thesis a simple and new technique are presented to determine the maximal singula...
