The invention belongs to the field of plant processing and phytochemistry, in particular to an antibacterial active substance in a water chestnut rhizome and an extraction method thereof. The method comprises the following steps of S1, after washing and cutting the water chestnut rhizome, drying the water chestnut rhizome in the sun, grinding the water chestnut rhizome and obtaining water chestnut rhizome power; S2, fully mixing the water chestnut rhizome power obtained in S1 with an extractant in proportion and obtaining solution to be extracted, placing the solution to be extracted into an ultrasonic water bath to ultrasonic extract, and after that, carrying out suction filtration and slag removal, and obtaining clear extracting solution; S3, placing the extracting solution obtained in S2 into a rotary evaporator to carry out vacuum rotary evaporation and recycling the extractant, and after evaporating to dryness, obtaining the antibacterial active substance. The antibacterial active substance in the water
