|---|---|---|---|
| 0.5% ninhydrin in acetone | Amino acid | Yellow spots | Absence of amino acid but presence of secondary amine |
| 10% SbCl3 in chloroform | Terpenoid | Green zones with different intensities | Absence of carotenoid; presence of terpenoids |
| Vanillin in H2SO4: CH3COOH:CH3OH |
Terpenoid | Purple zone | Presence of terpenoids |
| Dragendorff's reagent | Alkaloid | Orange zone | Presence of alkaloids |
| 5% FeCl3 (aq) | Phenolic compound | Some green zones | Presence of phenolic |
