[0029] A new eight-membered ring diene compound containing amino and carboxyl groups, (2E,6Z)-2-amino-2,6-dienecarboxylic acid, its molecular structure is shown in (IV);
[0030]
Embodiment 2
[0031] Example 2: A preparation method of a new eight-membered cyclodiene compound containing amino and carboxyl groups
[0032] A preparation method of a new eight-membered ring diene compound containing an amino group and a carboxyl group, comprising the following steps:
[0033] 1. Fermentation broth preparation
[0034] Js-1 T After the strain was inoculated on PDA slant medium and cultured at 28°C for 7 days, the spores were scraped and inoculated in 100mL PDA liquid, and cultured at 28°C with 180r / min shaking for 48h, which was the seed medium; 5mL seed medium was inoculated into 100mL liquid fermentation medium (maltose 15g, glucose 10g, starch 5g, yeast powder 5g, KNO 3 2g, MgSO 4 0.5g, K 2 HPO 4 1g, NaCl0.5g, water 1000mL, pH7.0;), 28°C, 180r / min shaking culture for 6 days, the culture solution was centrifuged at 8000r / min for 10min, and the supernatant was Streptomyces Js-1 T of fermentation broth.

Embodiment 3
[0069] Embodiment 3, a kind of new eight-membered ring diene compound (C containing amino and carboxyl) 9 h 13 NO 2 )the use of
[0070] C 9 h 13 NO 2 The bacteriostasis rates to harmful Verrucospora, Phomopsis, Aspergillus niger, and longan scorch rot pathogens were 100%, 92.78%, 80.56%, and 58.33%, respectively. The specific bacteriostasis test methods are as follows:
[0071] Determination of fungal growth inhibitory activity adopts poisoned plate assay method, and the C prepared into 5mg / mL is taken 9 h 13 NO 2 Mother liquor, add the mother liquor to the solid PDA medium with a temperature of 50°C to obtain a poisoned medium with a final concentration of 25 μg / mL, mix it evenly and pour it into a flat plate, and inoculate the test medium with a diameter of 0.6cm after the medium is solidified. Bacteria cake of fungal pathogenic bacteria, with non-toxic medium as control. Cultivate at 25°C, measure the activity of the active substance by the growth rate method, tha...
