abstract = {Tree peonies (Paeonia ostii and Paeonia rockii) are popular ornamental plants. Moreover,
these plants have become oil crops in recent years. However, there are limited compositional
studies focused on fatty acids. Therefore, this work aims to reveal compositional characteristics,
regarding fatty acids, sterols, γ-tocopherol and phenolic compounds, of tree peony seed oils from
all major cultivation areas in China, and to compare with herbaceous peony seed oil. For that,
an integrative analysis was performed by GC-FID, GC-MS and UHPLC-Q-TOF-MS technologies.
The main fatty acid was α-linolenic acid (39.0–48.3%), while β-sitosterol (1802.5–2793.7 mg/kg) and
fucosterol (682.2–1225.1 mg/kg) were the dominant phytosterols. Importantly, 34 phenolic compounds,
including paeonol and “Paeonia glycosides” (36.62–103.17 µg/g), were characterized in vegetable oils
for the first time. Conclusively, this work gives new insights into the phytochemical composition of
peony seed oil and reveals the presence of bioactive compounds, including “Paeonia glycosides”.},
