Anthocyanidin extract in methanol showed 3 absorption peaks, at 270, 340 and 520 nm, in the UV-vis spectrum, with bathochromic and hypsochromic shift with methanol+AlCl3 and methanol+AlCl3+HCl, respectively; the ratio of the absorbance at 440 nm to that at 520 nm was 0.29. No fluorescence occurred under UV irradiance, and 5 absorption peaks occurred at 270 nm after HPLC. Five molecular ion peaks occurred on MS: 595, 381, 611, 587 and 571, respectively, and monosaccharides in the extract were identified as rhamuose and glucose on HPLC.

The four protozoa had different changing patterns in rhizosphere and nonrhizosphere soil. About 90 times more Colpoda were determined in rhizosphere than in nonrhizospher at 52 days after sowing. There were more Anweba in rhizosphere than in nonrhizosphere at 74 days after sowing. Much more Bodo were found in rhizosphere at 32 days alter corn sowing. However, the number of the Bodo in rhizosphere soil was only 10% of that in the nonrhizosphere soil at 52 days after sowing. Rhizosphere always contains more Cercomonas than nonrhizosphere within the whole growing season of corn.
