ABSTRACT The exercise was about the techniques in proper sectioning of plant tissues and staining techniques so that the study of plant structure will be easier. In free hand sectioning‚ the plant organ must be 45° upright and is held between the thumb and the base of the forefinger. A razor blade was used to cut the plant thinly in cross sections. Obliquely cut tissue is a big mistake since the surface of the tissue will not be even upon viewing under the microscope. Iodine-Potassium-Iodide

It has fruits or berries that are stalkless‚ spherical‚ and purple when mature. Studies of the pigment extracted from its fruits showed that the intensely purple juice from the

Separation of Plant Pigments from Tomato Paste ABSTRACT In column chromatography a mixture is dissolved in a solvent and poured over a column of solid adsorbent then eluted with the same or a different solvent. This method is often used for preparative purposes; when a relatively large amount of the mixture and the components need to be isolated. The two main pigments in tomato paste mixture are the yellow-orange β-carotene and the red lycopene. The colors of these pigments are because

NOTES AND COMMENT 343 DETERMINATION OF CHLOROPHYLL AND PHEO-PIGMENTS : SPECTROPHOTOMETRIC EQUATIONS~ It has been shown that chlorophyll degradation products may at times constitute a significant fraction of the total green pigments present in seawater (Yentsch and Menzel 1963; Lorenzen 1965; Yentsch 1965). These degraded forms‚ or inactive chlorophyll‚ absorb light in the red part of the spectrum; if they are present in concentrations significant relative to chlorophyll a‚ a serious error

INTRODUCTION SilCote aluminum pigment is manufactured by mixing aluminum paste with Monomer‚ SR-350 (trimethylolpropane trimethancrylate) and additive‚ Z-6040 which is an epoxy-functional Silane (3-glycidoxypropyl trimethoxy silane)‚ in a jacketed mixer with the presence of catalyst‚ ABIN (azo-bis-isobutyronitrile). White spirit‚ acts as the carrier solvent in the process. 2. PROCESS FLOW The aluminum paste is first loaded into the jacketed mixer‚ followed by introducing a pre-determined
