3,5,4''-Trihydroxy-7-methoxyflavone

After oral administration of A. complanatus extract (10 mL/kg) to rats (equivalent to 17.6 mg/kg Rhamnocitrin), blood (approximately 0.3 mL) is collected from the ocular vein for analysis at 0, 0.083, 0.167, 0.25, 0.333, 0.5, 0.75, 1, 2, 4, 6, 9, and 12 hours after administration under ether anesthesia. The results shows that the plasma concentration of Rhamnocitrin reached its maximum at 0.65 hours, with an average C_max of 29.57 ng/mL^[1].
