The paeoniflorin content in the root of Paeonia lactiflora in different years (1, 2, 3, 4), and the paeoniflorin content in the root of Paeonia lactiflora in different periods of the same year (germination, leaf expansion, flowering, fruit maturity, late withering) were determined to determine the best harvest year and the best harvest time. At the same time, according to the standards provided in the 2015 Chinese Pharmacopoeia, the quality evaluation of paeonia rubra in the nursery of Bayantohai Town, Ewenke Banner was made. The results showed that the content of paeoniflorin was the highest at the age of 4 years, 3.07%; The paeoniflorin content in the root was the highest at the late stage of withering in the same year, which was 3.34%. Therefore, the harvesting year and time of Paeonia lactiflora root are 4 years old and late withering respectively.
