The invention discloses an ethanol gradient extraction process and application of the ethanol gradient extraction process in plant extraction. The extraction process comprises the following steps: 1) crushing plants to 200 meshes or more; (2) soaking the crushed plants into deionized water, and adding ethanol for multiple times, so as to extract the plants for 3-5 hours through different ethanol concentration gradients; and 3) combining the extracting solutions, and performing rotary evaporation and concentration to obtain the plant extract. By adopting the extraction process disclosed by the invention, plant active matters can be extracted more sufficiently and more effectively, the extract is high in stability, and the antibacterial effect on dandruff pathogenic bacteria malassezia, gram-positive bacteria staphylococcus aureus, gram-negative bacteria escherichia coli, fungi candida albicans and mold aspergillus niger is remarkably improved. 本发明公开了一种乙醇梯度提取工艺及其在植物提取中的应用，所述提取工艺包括以下步骤：1)植物粉碎至200目以上；2)粉碎的植物浸泡入去离
