The literature review shows that study of reactions of ninhydrin
is a subject of more interest and some of the useful reactions such as amidoalkylation, Knoevenagel condensation , oxidation [7,8], reduction [9,10], reaction with enols and aromatic compounds , synthesis of heterocyclic compounds , Friedel-Crafts type reaction [13-16], Kolbe-Schmitt , Passerini , Wittig  and Morita-Baylis-Hillman  have been investigated in this area.
test used here to evaluate honeydew production is widely used for antifeedant activity studies on aphids (Sadeghi et al.
On analytical balance 2 g of ninhydrin
was weighed, then dissolved in 3 ml ethanol, diluted with water to 100 ml, adjusted to pH 7.
Finger printing using cyanoacrylate fuming and ninhydrin
The amino acid contents in CV aqueous extract was determined by ninhydrin
colorimetric method (Oka et al.
Different plant Tests constituents Test for alkaloids Mayer's test, Dragendroff's test, Wagner's test, and Hager's test Test for proteins and Millon's test, Biuret test, and amino acids ninhydrin
test Test for anthraquinones Modified Borntrager's test Test for flavonoids Ferric chloride test and lead acetate test Test for carbohydrates Molisch's test Test for reducing sugars Fehling's test and Benedict's test Test for saponins Foam formation test Test for tannins Ferric chloride test and lead acetate test Test for steroids, Liebermann-Burchard test, triterpenoids, and Salkowski test, Noller's test, cardiac glycosides Legal's test, Baljet test, and Keller Kiliani's test TABLE 2: Effect on electrolyte excretion in urine.
The section then moves into discussion of fingerprints in blood, vacuum metal deposition, the cyanoacrylate fuming method, ninhydrin
analogues, nanoparticles, friction ridge detection, statistics and probability, and digital imaging.
As a result, it was confirmed that much protein was included in carbonate warm water by a ninhydrin
John Iwanik said ninhydrin
gas being used in the lab may have escaped from the ventilation system.
The eluted spots were sprayed with resorcinol-sulphuric acid, ammonium molybdate, ninhydrin
, a-naphthol and Dragendorff spray reagents for further confirmation (Prabhakara et al.
The A spot was positive for both Millon's and the Ninhydrin
in acetone by spraying with a solution of 0.
