Embodiment 1
[0038] Embodiment 1 is a preparation method and application of a water-based safe plant antibacterial agent disclosed by the present invention, which specifically includes the following steps:
[0039] S1. Extraction: using supercritical extraction method, with CO 2 The fluid is the extractant, and pure water is used as the entrainer to extract plant essential oils from camphor leaves, citronella leaves, lavender leaves, eucalyptus leaves, lemongrass leaves, and jasmine leaves. The mass ratio of pure water to each raw material is 1: 1;
[0040] Among them, the supercritical extraction parameters of cinnamon camphor leaves are: extraction temperature is 45°C, extraction pressure is 20Mpa, CO 2 The fluid flow rate is 14L / min, the static extraction time is 70min, and the dynamic extraction time is 70min;
[0041] The supercritical extraction parameters of citronella leaves are: extraction temperature is 45°C, extraction pressure is 15Mpa, CO 2 The fluid flow rate is 35L / min, t...
