Abstract/OtherAbstract:
The metabolite produced by Mycosphaerella pinodes, the causal agent of mycosphaerella blight on field peas, was detected by thin layer chromatography (TLC) and was analyzed for its chemical and pathogenic characteristics. One blue dot was detected using 254nm UV light on TLC plate, and a spray of rho-anisaldehyde (110 degrees C, 30 min) also produced a blue dot. The solvent systems used for TLC analysis were ethyl acetate/water/acetone (5/2/5), chloroform/methanol/glacial acetic acid (19/10/2), toluene/ethyl acetate/90% formic acid (6/3/1), diethylether/methanol/water/90% formic acid (95/4/1/1), and bezene/methanol/acetic acid (24/2/1), with R(f) values (min-max) of 0.09-0.18, 0.88-0.95, 0.06-0.15, 0.39-0.47 and 0.05-0.12, respectively. The recovered metabolite from the TLC plate displayed UV absorption peaks at 212, 244, 250, 256 and 261 nm. The proposed formula of the main component of the metabolite was C16H12N3O6. The TLC-purified metabolite induced symptom of discoloration on detached pea leaves.
