1. A water-purifying agent, comprising:
an extract, being formed of:
a fractionated component 1 of a water extract of a plant powder and a polymeric flocculant,
wherein the fractionated component 1 is a fractionated component having a fractionation molecular weight of 12,000 or greater,
wherein an ethanol-undissolved component of the fractionated component 1 exhibits a peak attributable to carboxylic acid in a Fourier transform infrared spectroscopy (FT-IR) measurement and exhibits a peak attributable to cellulose in a gas chromatography mass spectrometry (GC-MS) measurement,
wherein an ethanol-dissolved component of the fractionated component 1 exhibits a peak attributable to carboxylic acid in the FT-IR measurement and exhibits a peak attributable to a plant protein in the GC-MS measurement, and
wherein the water extract of a plant powder is a water extract of ethyl acetate extraction residue of a plant powder.
