Figure 3: Histochemistry of trichomes of Coleus forskohlii. Ferric chloride (a and b), aluminum trichloride (c and d), Sudan III (e and f), concentrated sulfuric acid (g and h), and 2.4-dinitrophenylhydrazine (i and j) staining showed secreted material stained bright green, week green, pink-red, yellow, and light black, respectively. Scale bars = 25μm (a, g and h), 10μm (b), 100μm (c and i), 50μm (d, e and j)
