Stachyose tetrahydrate, a functional oligosaccharide, acts as a prebiotic. Stachyose tetrahydrate can prevent indirectly colon cancer cell growth by promoting the proliferation of probiotics or producing beneficial materials in the intestine^[1][2].

Stachyose tetrahydrate inhibits Caco-2 cell proliferation and induces apoptosis in a dose-dependent manner^[1].
Stachyose highly promotes proliferation of lactic acid bacteria (LAB) by inducing LAB to produce more α-galactosidase to hydrolyze stachyose^[2].

Mice^[1]

Male Kunming mice in each group (n=8) are administered by intragastric gavage with saline, stachyose (250 mg/kg bw), genistein (100 mg/kg bw), and stachyose (50, 250, and 500 mg/kg bw) together with genistein (100 mg/kg bw) for 4 consecutive weeks, respectively, and then their urine, feces, blood, gut, and liver are collected^[1].
