Quercetin 3-(6″-caffeoylsophoroside) is an orally active compound exhibiting α-amylase inhibitory activity with an IC50 value of 73.66 μg/mL, and demonstrates antidiabetic effects through the reduction of oxidative stress. It is found in the hydro-methanolic extract of Cardamine hirsuta Linn and is utilized in diabetes mellitus research [1].

Quercetin 3-(6″-caffeoylsophoroside) at doses of 50, 100, 500, 1000, and 2000 mg/kg administered orally was found to be safe in acute oral toxicity tests with SD rats, indicating its potential for anti-diabetic research [1]. Additionally, this compound at 125, 250, and 500 mg/kg doses effectively improved type 2 diabetes in SD rats by reducing oxidative stress and inhibiting α-amylase activity [1].
