实验法

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.

Methods:(1) Silica column chromatography and LH-20 were used in phytochemistry study.(2) Based on the extraction ratio of arctiin, the best extraction procedure was acheived under the direction of L9(34) orthogonal experimental design. From 10 types of resins, the one with the maximal binding ability for Arctii was selected and silica-column choramatograpy was used in its seperation and purification procedure.(3) The animal diabetic experimental model in Wistar rats was established with streptozotocin and many biochemical factors were used to indicate the pharmacological effects of arctiin, including glycosylated hemoglobin, serum creatinine, seralbumin, monoxide nitrogen, glycerin trilaurate, cholesterol, HDL-ch, LDL-ch, Blood urea nitrogen, creatinine, SOD, ET, MDA, total Urine protein and albuminuria.
