A Thin - Layer chromatographic(TLC) procedure has been developed for the separationand identification of Jingangmeisu aqueous solution which was separated on silica gel plate with propanol - glacial acetic acid - water (4:1:1) as the developer and detected at fluorescence.

Determination of Validamycin A Residues in Soil by Precolumn Derivatization and Capillary Gas Chromatography;

The active components,buprofezin,Shachongdan and validamycin A in the wettable powder were determined by RP-HPLC.

But validamycin A is hardly effective ((EC50=66.

Optimization of Production Processes of Agricultural Antibiotics Jinggangmeisu;

Synthesis of Polyacrylic Acid Resin and Its Application in Jinggangmeisu Extraction;

Controling of Bacterial-infection in the Fermentation Process of Jinggangmeisu;

Studies on the Toxicity and Mechanism of Jinggangmycin A on Rhizoctonia solani AG-1 IA[ in vitro (on PDA) and in vivo (in rice plant)];

Based upon the analysis of the physicochemica properties of soil,Influence of bacillus thuringiensis and jinggangmycin A on soil invertase activitiy in different concentration and PH were measured in simulated conditions with 3,5-Dinitrosalicylic Acid Colorimeitry.

jinggangensis Yen was treated by UV,60Coγ Radial and UV with HNO2 respectively, a high-yield Jinggangmycins A strain F-101 was obtained, the Jinggangmycin A yield was 33.
