Abstract: By HPLC resveratrol in grape purple peony, peanuts and giant peak distribution of each part the development and utilization of these plants can provide valuable data. The content of purple peony seed and pod was far higher than that in the peanut and the giant peak grapes. Peanut resveratrol content was the lowest. Grape purple peony, peanuts and giant peak resveratrol distribution of each part were as follows: purple peony leaf, purple peony collateral, purple peony stems and purple peony root did not contain resveratrol, and the purple peony seeds and purple peony pod contained resveratrol, the purple peony seed resveratrol content was 0.87‰, and purple peony pod resveratrol content was 0.26‰. Peanut leaf, peanuts, peanut embryo and endosperm did not contain resveratrol, peanut collateral, peanut stem, peanut shell, peanut coat, peanut lateral root and peanut root contains resveratrol contains resveratrol, and the contents were 3, 11, 12, 15, 5 and 10 mg·kg^-1 in lateral branch, peanut stalk, peanut shells, peanut coat, lateral root and peanut taproot, respectively. The grape flesh, grape skins and grape seed, grape pedicle, resveratrol were in four parts, including the resveratrol content in grape flesh 0.017‰, grape skin resveratrol content of 0.028‰, grape seed extract resveratrol content of 0.005‰, grape pedicle and its adjacent branch resveratrol content was 0.12‰. Therefore, peanut coat, peanut shell, grape skin and grape seed, grape pedicle, peony seed, and peony pod have the medical value and economic value.
