The invention provides a method for extracting platycodin D from platycodon grandiflorum and aims to mainly solve the problems that the prior art is complex to operate, low in product content, low in recycle rate and unsuitable for large-scale production operation. The method for extracting platycodin D from the platycodon grandiflorum comprises the following steps: (1) extraction; (2) primary ultrafiltration; (3) secondary nanofiltration; and (4) recrystallization. The method for extracting platycodin D from the platycodon grandiflorum can be used for preparing a platycodin D product of which the purity is higher than 98% by just a plurality of steps, and is convenient to operate, high in product content, high in recycle rate, small in harms caused by solvents and suitable for large-scale production operation.
